Artificial intelligence for industry<br />
Dear Readers,<br />
Artificial intelligence is a buzzword with distinct utopian overtones. Just about everyone has heard about ChatGPT,<br />
a program that can write texts of the same quality as a well educated person. Or about LamBDA, the computer that<br />
claims to have a consciousness and gives very human answers to questions. And who among us hasn’t seen a service<br />
robot? These are just three examples of a technology that is currently coming to the forefront in its first generation.<br />
Experience has shown that a better, stronger second generation of modern technologies quickly follows. Many<br />
renowned companies are already working on this. I am therefore confident that AI will establish itself in just a few<br />
years, just as the mobile phone and the Internet took hold and are now part of our daily routine. But what does that<br />
mean for our future? Soon, computers or robots will be able to do anything that is not directly creative, subject to<br />
changing requirements or mechanically complicated, and does not require strategic decisions linked to emotions to be<br />
made – even the production, assembly, monitoring and control of machines. On the other hand, AI can support the development<br />
of new products. Examples include circuit design, energy-optimised structures and social network effects.<br />
Is artificial intelligence a threat or an opportunity? But perhaps that isn’t the right question. Maybe I have to take a<br />
totally different approach: Central Europe is headed for a labour shortage crisis. According to the December 2022 edition<br />
of ZEIT magazine, the demand for workers is going to exceed the supply by up to 5 million people in 2035. Many<br />
jobs will be left without anyone to do them. So it would be better for us to reserve the challenging part of a job for ourselves,<br />
and to understand AI as a helpful technology that assists us in daily life. I would even go so far as to say that the<br />
country that makes this transition most effectively and quickly will have an advantage. This could mean faster, better<br />
product development or optimal system architectures. That being said, nobody really knows yet what areas are going<br />
to be affected. We should however assume that it will be of very high social and industrial relevance. Naturally one<br />
also has to consider the taxation of such services, the value of the work, working hours and the society that will subsequently<br />
establish itself. We will certainly have to reorganise ourselves and social factors must not be disregarded.<br />
Let’s take ChatGPT as an example. Using this program could streamline work processes in public or also industrial<br />
administration by having a few employees merely enter keywords, check the results that are produced, and then<br />
approve and send them out. Future workers, who are currently students, are already able to handle this.<br />
In an industrial application, for example, an AI system reports that a fault has been detected in a machine, indicating a<br />
damaged seal. The AI system could not only initiate the seal replacement but also order the new part. AI could propose<br />
how a circuit design can be improved, or assist with the programming of new software. AI is able to respond effectively,<br />
extremely quickly and rationally. Thus the first question we should ask is where using AI will be the most helpful. Have<br />
courage and seek advice. It’s worth your while.<br />

Artificial intelligence and the digitalisation<br />
of process components<br />
Prof. Dr.-Ing. Eberhard Schlücker, Dominik Haspel<br />
<strong>Process</strong> components and process<br />
technology systems have moving<br />
fixtures and fittings. Substances<br />
pass through them, they are controlled<br />
electronically or electrically,<br />
moved electrically or with flow<br />
forces. They move liquids, gases<br />
and solids. As a result, forces are<br />
exerted on the component that,<br />
when measurable, also provide information<br />
about the condition or<br />
state. Thus the response to a controlling,<br />
driving or conveying action<br />
necessarily contains information<br />
about the device or machine. This<br />
may be visible directly in the current<br />
profile or indicated by vibrations.<br />
The latter tends to be the result of<br />
pulsing disturbances (all natural frequencies<br />
are excited) and intermittent<br />
events, which are usually typical<br />
for the type of damage.<br />
While the signals that are visible in<br />
load curves and control characteristics<br />
can be analysed relatively well in<br />
a chronological sequence, are easily<br />
and well recognised by computers<br />
and can be used for control purposes,<br />
vibration signals are somewhat more<br />
difficult to analyse and comprehend.<br />
At the same time however, they are<br />
the more interesting sources of information<br />
for (early) fault detection.<br />
They are the first indication we have<br />
of a fault, as soon as a mechanism<br />
develops a very small defect that<br />
can still be repaired in many cases,<br />
but the damage is not yet significant.<br />
Vibration measurements therefore<br />
support genuine early fault detection.<br />
That being said, how do we analyse<br />
and interpret vibrations correctly?<br />
A first step of such an analysis is<br />
to convert the data from the time domain<br />
to the frequency domain with<br />
the Fourier transform (FT). Measurements<br />
in practice consist only of values<br />
at discrete times of measurement.<br />
Consequently, a discrete<br />
Fourier transform is applied that determines<br />
amplitudes for discrete frequency<br />
values. However, these are<br />
always burdened with deviations<br />
due to the leakage effect or frequencies<br />
between two discrete frequency<br />
values. Individual aspects of the discrete<br />
transform can be improved with<br />
the application of various window<br />
functions (Figure 1). For example,<br />
the mathematical leakage effect can<br />
be reduced or the amplitude can be<br />
correctly described, but not both at<br />
once. In addition, measurements always<br />
contain a certain amount of additional<br />
noise, which is also found in<br />
the Fourier-transformed spectrum.<br />
AI-based approaches can be used<br />
here to identify these influences and<br />
correct for the resulting deviations.<br />
Vibration analysis<br />
As a rule, vibration patterns for early<br />
fault detection are based on structure-borne<br />
sound measurements.<br />
Structure-borne sound sensors are<br />
therefore required. Since their functioning<br />
is non-invasive, they can be<br />
easily installed anywhere. Measuring<br />
close to the sound source of the functional<br />
component being monitored is<br />
important here.<br />
Frequency images obtained from<br />
these measurement data using FT<br />
represent an intransparent mass<br />
of information for many, even experts.<br />
One often puzzles over which<br />
peak means what. However, a basic<br />
rule can help: The higher the amplitudes<br />
are overall, the greater the<br />
probability of damage. But to find<br />
out exactly what the damage is, or<br />
to identify initial signs of impending<br />
damage early on, one needs to go<br />
deeper and quickly encounters difficulties.<br />
Algorithms that process the<br />
data and provide additional information<br />
can be extremely helpful here.<br />
The four diagrams in Figure 2<br />
show what errors can occur even<br />
during measurement. On the left,<br />
Fig. 1: Transform results with different<br />
window functions.<br />
you see the signal sequence with a<br />
high sampling rate. Below that is the<br />
Fourier transform that, corresponding<br />
to the measurement signal, exhibits<br />
numerous frequency peaks<br />
and seems difficult to interpret. On<br />
the right, you see the same signal sequence<br />
with a lower sampling rate<br />
and a transform result consisting of<br />
only a few discrete frequencies. It differs<br />
considerably from the spectrum<br />
on the left.<br />
The second rule we can derive<br />
from this is that we need a high sampling<br />
frequency to correctly capture<br />
reality. A good recommendation for<br />
this is based on the natural frequencies<br />
of small components, indicating<br />
a sampling frequency of 20 KHz.<br />
To evaluate such signals, one<br />
now attempts to extract those peaks<br />
from the spectrum as a whole that<br />
belong to actually occurring frequencies<br />
in the measurement signal, and<br />
to exclude those caused by interfering<br />
factors due to the transform.<br />
The peaks extracted in this way and<br />
their corresponding amplitude value<br />
are then used to reconstruct the<br />

unadulterated signal as accurately as<br />
possible.b Neural networks, for example,<br />
can be used to differentiate<br />
whether a large amplitude value corresponds<br />
to a peak or was caused by<br />
interfering factors. One can imagine a<br />
neural network as an extremely complex<br />
function with a very large number<br />
of variables. The input values for<br />
this function are the spectrum being<br />
evaluated, and the result is a statement<br />
whether there is a peak for<br />
each frequency of the spectrum. With<br />
the skilful construction of this “neural<br />
function”, it can be derived according<br />
to its individual variables. Assuming<br />
one now has training data (input<br />
values and the corresponding correct<br />
answers), these derivations can be<br />
used to determine how the individual<br />
variables have to be changed so<br />
that the result of the function corresponds<br />
as closely as possible to the<br />
correct answers. With a large volume<br />
of such training data, all variables can<br />
thus be optimised so that the total<br />
error of the function as a whole for<br />
the training set is as small a possible.<br />
With a sufficiently large and diverse<br />
training set, one can subsequently<br />

assume that the neural network can<br />
represent the underlying principles.<br />
It will therefore obtain corresponding<br />
good results for new, unknown input<br />
data as well.<br />
Results of such a neural network<br />
with corresponding training are<br />
shown in Figure 3. The Convolutional<br />
Neural Network (CNN) used in this<br />
case is composed of a series of mathematical<br />
convolutions. Here the individual<br />
entries in the respective convolution<br />
matrix are the variables to<br />
be optimised. With this construct, the<br />
same processing steps are applied<br />
at every position of the frequency<br />
spectrum. Hereby the principle that<br />
can be determined at a point in the<br />
spectrum from its surrounding values<br />
must be able to define whether<br />
this is a regular peak. Such peaks do<br />
not have to be “learned” separately<br />
for each frequency value, but are<br />
executed in the same way for every<br />
frequency. As a result, the network<br />
then supplies a value between 0 and<br />
1 for each frequency, reflecting how<br />
“certain” the network is that there is<br />
a real peak at the respective position.<br />
As a design parameter, one now still<br />
has to choose a suitable threshold<br />
at which one assumes that there is<br />
in fact a peak. Figure 3 presents an<br />
examination of the influence of this<br />
threshold. A signal of three vibrations<br />
(green markings) and additional<br />
white noise was examined for this<br />
purpose. Here the ratio of the vibration<br />
amplitude to the average noise<br />
intensity and the selected threshold<br />
were varied. The average noise intensity<br />
increases from no noise on the<br />
left to intense noise on the right. The<br />
required threshold for the positive<br />
identification of a peak (red markings)<br />
increases from top to bottom.<br />
One can see that increasing noise<br />
causes additional false positive identifications<br />
(see the right-hand column<br />
in particular). The number of false results<br />
can be reduced by choosing a<br />
higher threshold. However, note that<br />
setting the threshold too high can<br />
also cause false negative results (existing<br />
peaks are missed) (see the bottom<br />
row in particular).<br />
When a suitable threshold is selected,<br />
all real peaks can be identified<br />
and there are few false positive<br />
results, even with intense noise.<br />
Overall it was shown in this case that<br />
the detection of peaks using neural<br />
networks produced better results<br />
than comparable, conventional<br />
peak detection methods. Especially<br />
in cases with high noise levels, neural<br />
networks were able to produce<br />
signifi cantly better results.<br />
This example shows how AIbased<br />
algorithms can complement/<br />
improve classic approaches or support<br />
manual evaluations with additional<br />
information in the evaluation of<br />
vibration spectrums. Such methods<br />
also have potential for subsequent<br />
evaluation steps. A neural network<br />
could provide comparable support in<br />
obtaining a more exact, undisturbed<br />
value for the respective amplitudes of<br />
the individual frequencies.<br />
In contrast to manual evaluation,<br />
algorithms can, for example, take into<br />
account the information from numerous<br />
different window functions at<br />
the same time. Additional application<br />
possibilities for AI-based methods<br />
can also be identified for the subsequent<br />
evaluation of the peaks that<br />
are found. For example, grouping<br />
multiple peaks into a basic vibration<br />
and their corresponding harmonics<br />
is a task one should be able<br />
to automate using machine learning.<br />
Overall, AI-based methods have<br />
great potential for the automation of<br />
evaluation steps that currently have<br />
to be performed manually as a rule.<br />
More elaborate evaluations, which<br />
are currently carried out manually in<br />
isolated cases only, will therefore be<br />
automated in the future and available<br />
for live monitoring.<br />
Consequently, increasingly small<br />
changes in the spectrum can be evaluated.<br />
Changes (and possible impending<br />
damage) can be detected earlier,<br />
and discerning between different<br />
changes (for example, different types<br />
of damage) can be improved.<br />

Hydrogen<br />
Anything but standard: Elastomer seal<br />
challenges in hydrogen applications<br />
Dipl.-Ing. (FH) Michael Krüger<br />
Mobility, the energy sector and industry<br />
– there is tremendous potential<br />
for modern hydrogen technologies<br />
in many areas. Hydrogen is of<br />
central importance as a versatile<br />
energy carrier and offers new possibilities<br />
for production processes<br />
as a chemical raw material. Therefore,<br />
science and industry experts<br />
are conducting intensive research<br />
in the vast field of hydrogen technologies<br />
and continuously develop<br />
their practical applications. The optimal<br />
coordination of components is<br />
among the most important success<br />
factors here. In particular, the seals<br />
being used are of the greatest importance<br />
in terms of functionality.<br />
Countless projects in the mechanical<br />
engineering segment are therefore<br />
dedicated to this topic. A central difficulty<br />
at this juncture for both users<br />
and seal manufacturers is that hydrogen<br />
projects and their applications<br />
are rarely comparable to each other.<br />
This difficulty begins with the umbrella<br />
term “hydrogen applications”. It describes<br />
an extensive domain starting<br />
with H 2<br />
production and extending to<br />
transportation and distribution as well<br />
as the use and consumption of hydrogen.<br />
Many projects are still in the development<br />
phase, which means development<br />
teams are not making any<br />
project details public, protecting their<br />
development advantage for market<br />
strategy reasons. This in turn tends<br />
to produce individual solutions rather<br />
than standard applications.<br />
Choosing a suitable elastomer<br />
sealing material in the hydrogen environment<br />
is of vital importance. All<br />
operating parameters that occur in a<br />
real-world application must be taken<br />
into account.<br />
The following requirements for<br />
sealing materials (selection) have to<br />
be clarified:<br />
− Chemical resistance for all media<br />
that may come into contact with<br />
the seal (during operation, during<br />
assembly)<br />
− Temperature resistance (ambient<br />
temperature, operating temperature,<br />
also absolute short-term peak<br />
temperatures)<br />
− Pressure resistance, also in case of<br />
pronounced pressure fluctuations<br />
(resistance to explosive decompression<br />
where applicable)<br />
− Good physical properties (compressive<br />
deformation test, stress<br />
relaxation)<br />
− Low permeation (gas permeability)<br />
Hydrogen permeation<br />
Hydrogen permeation is an important<br />
selection criterion. Since the colourless<br />
and odourless H 2<br />
gas is highly<br />
inflammable and the production of<br />
molecular hydrogen is complicated<br />
and expensive, preventing volatilisation<br />
is essential for both safety and<br />
cost reasons. The H 2<br />
permeation coefficient<br />
varies considerably between<br />
the ASTM classes (elastomer material<br />
groups) and there are significant differences<br />
between the materials within<br />
an ASTM class as well. VMQ (silicone),<br />
for example, has a very poor<br />
permeation coefficient, EPDM has a<br />
much better one and FKM (fluororubber)<br />
has the best value in comparison.<br />
The temperature has a significant influence<br />
on the result as well. A value<br />
determined at 23 °C may, for example,<br />
exhibit a factor of +5 for EPDM<br />
Fig. 1: Test setup H 2<br />
permeation test (all photos © : COG<br />
materials and a factor of +3 to over 16<br />
for FKM at 80 °C. Tested materials are<br />
therefore clearly recommended in H 2<br />
applications.<br />
The field of application itself can<br />
also be an important selection criterion.<br />
Seals for natural gas containing<br />
hydrogen (in distribution/transport,<br />
for example) have to meet the<br />
requirements of the DVGW:<br />
− Gases according to DVGW worksheet<br />
G 260 (max. hydrogen content<br />
10 %)<br />
− DIN-DVGW certification of the sealing<br />
material according to DIN<br />
EN 549 and/or DIN EN 682<br />
− Typical operating temperature<br />
ranges:<br />
− DIN EN 549: -20 °C to +80 °C<br />
(class B2)<br />
− DIN EN 682: -15°C to +50°C<br />
(type GBL)<br />
− Typical pressure ranges:<br />
− Up to 5 bar (DIN EN 549)<br />
− Up to 100 bar (DIN EN 682)<br />

A comprehensive survey of the application<br />
process is essential for the selection<br />
of materials.<br />
Practical example –<br />
hydrogen electrolyser<br />
Permeability is not always the decisive<br />
selection criterion. A manufacturer of<br />
AEM (anion exchange membrane)<br />
electrolysers for hydrogen production<br />
experienced major problems with the<br />
elastomer seals. The chosen NBR material<br />
failed after a short time. The<br />
medium in the electrolyser was 5 %<br />
caustic potash solution (KOH) at max.<br />
65 °C. The seal manufacturer COG<br />
suggested a peroxide cross-linked<br />
EPDM as a suitable material. Surprisingly<br />
this too failed after approximately<br />
100 hours. Exposure tests in caustic<br />
potash solution (KOH 5 %) at 65 °C did<br />
not result in any significant material<br />
changes. It was therefore presumed<br />
that the material incompatibility was<br />
related to the materials used in the<br />
electrolyser itself. AEM electrolysis requires<br />
a catalyst and nickel was used<br />
in this case. Nickel is known to be<br />
“toxic” to rubber. Ethylene propylene<br />
diene monomers (EPDM) are terpolymers<br />
made of ethylene, propylene<br />
and diene. Dienes contain two carbon-carbon<br />
double bonds (C=C double<br />
bonds). Nickel attacks precisely<br />
those double bonds in diene and destroys<br />
the rubber.<br />
COG then proposed using an<br />
ethy lene propylene copolymer (EPM).<br />
This rubber does not contain diene<br />
and therefore has no double bonds<br />
in the polymer. Its resistance to caustic<br />
potash solution in the specified<br />
temperature range is very good. The<br />
chosen EPM O-ring exhibited no significant<br />
changes after being used for<br />
more than 6000 hours.<br />
This example shows that different<br />
and in part complex circumstances<br />
may play a significant role in the<br />
evalu ation of suitable sealing materials<br />
for hydrogen projects.<br />

Sealing flagship project<br />
The independent manufacturer<br />
C. Otto Gehrckens (COG) has developed<br />
the new H 2<br />
Sealing series of<br />
sealing materials for hydrogen applications.<br />
The company has accumulated<br />
extensive experience in<br />
various hydrogen projects and developed<br />
sealing solutions for a wide<br />
range of customers. This has resulted<br />
in two high-performance materials<br />
covering a broad range of hydrogen<br />
applications: An FKM and an EPDM<br />
compound specifically designed for<br />
hydrogen applications. Both materials<br />
are the result of intensive development<br />
efforts by the seal manufacturer<br />
and have proven their optimal<br />
suitability for use in hydrogen technologies<br />
in external tests of their hydrogen<br />
permeability (gas permeability)<br />
by an independent laboratory.<br />

Unafraid of hydrogen<br />
Dipl.-Ing. Norbert Weimer<br />
The topic in this paper is the sealing<br />
of hydrogen using static flat gaskets<br />
made of fibrous materials (FA). Hydrogen<br />
is being hailed as the “oil of<br />
the future”, underlining how many<br />
designers and practitioners will<br />
have to become familiar with using<br />
it in their construction projects,<br />
plant designs, procurement scenarios<br />
and assembly activities. This<br />
includes determining how to seal<br />
components properly when working<br />
with hydrogen. The aim of this<br />
article is to raise awareness of this<br />
issue and provide information to enable<br />
proper decision-making for the<br />
material selection and the installation<br />
situation.<br />
One of the most common forms of<br />
sealing is static sealing, where the<br />
components to be sealed remain<br />
immobile in relation to each other.<br />
With these connections, considerable<br />
pressure is exerted on the sealing<br />
material installed between the<br />
flanges - the high-pressure seal.<br />
To seal properly, the material<br />
used must be adaptable and migrate<br />
into the roughness of the flange surface<br />
as well as compensate for its<br />
waviness. Conversely, despite the<br />
high forces involved, the material<br />
must remain intact - a typical technical<br />
compromise.<br />
Klinger has developed a manufacturing<br />
process to meet this compromise:<br />
The calendering process involves<br />
processing a mixture of fibres<br />
and fillers with elastomer as a binder<br />
into a sealing sheet on a hot roller by<br />
exerting enormous pressure.<br />
The result is a highly resilient<br />
seal, typically capable of withstanding<br />
loads of over 200 MPa (approx.<br />
2 tonnes per cm²) at room temperature,<br />
which has the smallest of pores<br />
and allows adaptation to the surface<br />
roughness by compressing the pores<br />
and the elastomer.<br />
Pressing together, e. g. via screws,<br />
prevents surface leakage and leakage<br />
through the sealing material - the<br />
higher the sealing force, the tighter<br />
the connection.<br />
Leakage requirements<br />
for gas supply<br />
The DIN-DVGW type test according<br />
to DIN 3535-6 of April 2019 specifies<br />
corresponding values. The specific<br />
Static gaskets - Soft gaskets<br />
Fig. 2: Sealing surface and seal<br />
leakage rate must be ≤ 0.1 mg/(s x m).<br />
For FA gasket materials, a gasket<br />
thickness of 2.0 mm, internal pressure<br />
of 40 bar and surface pressure<br />
of 32 MPa are assumed. The test gas<br />
is nitrogen.<br />
So far, we have been using fossil<br />
media such as natural gas (predominantly<br />
methane) and propane and<br />
butane as standards for our energy<br />
supply. For these gases, the tightness<br />
requirements are sufficient - but<br />
what about hydrogen?<br />
Does hydrogen differ from the<br />
usual fuel gases?<br />
Fig. 1: Flange with high-pressure seal (Photo © : KLINGER)<br />
Hydrogen gas has a low density and<br />
the atom has very low spatial expansion.<br />
In fact, it is the smallest atom in<br />
16 PROCESS TECHNOLOGY & COMPONENTS <strong>2023</strong>
Hydrogen<br />
the periodic table of elements. This is<br />
why, in theory, it traverses the smallest<br />
channels with greater ease than<br />
larger atoms. The reality, however, is<br />
different, because hydrogen is only<br />
atomic when produced and immediately<br />
combines with the next hydrogen<br />
atom to form the hydrogen molecule<br />
H 2<br />
, which can be pictured in the<br />
shape of a dumbbell. Nevertheless,<br />
the fuel gases having proliferated to<br />
date, methane CH 4<br />
(the main component<br />
of natural gas), propane C 3<br />
H 8<br />
and butane C 4<br />
H 10<br />
are all clearly larger.<br />
Recent years have seen a growing<br />
shift in the use of helium (He) rather<br />
than nitrogen as the test gas for<br />
measuring any leakage from sealed<br />
joints. Accordingly, now we have the<br />
second-smallest atom in the periodic<br />
table of elements as our standard<br />
test gas, which is usable to detect<br />
the smallest leaks. Rather than being<br />
rigid, our gas particles move due<br />
to Brownian molecular motion. If we<br />
now compare the kinetic diameters<br />
of the relevant gas particles, we see<br />
that the helium atom and hydrogen<br />
molecule are comparable in size.<br />
In the table of kinetic diameters<br />
(www.arnold-chemie.de ) we see<br />
hydrogen H 2<br />
helium He<br />
and for methane CH 4<br />
3.8 Å<br />
where 1 Å = 0.1 nm<br />
2.3 – 2.9 Å<br />
2.6 – 2.7 Å<br />
And what we notice is that hydrogen,<br />
although “smaller” than methane,<br />
is on a par with our test gas helium,<br />
size-wise. Similarly, previous actual<br />
comparative measurements have<br />
shown that, despite differences in the<br />
quantities of hydrogen and helium<br />
leaking, they are of the same order of<br />
magnitude.<br />
One other thing to note about hydrogen<br />
is that it burns faster than natural<br />
gas, which explains the smaller<br />
distances between the burner nozzle<br />
and flame in gas burners. As a result,<br />
both the flame detection technology<br />
and the material selection of the<br />
burner nozzle and other parameters<br />
have to be adjusted. Furthermore,<br />
unlike other gases, hydrogen has a<br />
negative Joule-Thompson effect. But<br />
none of this is relevant in the context<br />
of tightness of connections.<br />
What practical experience<br />
do you have?<br />
Hydrogen has been a common raw<br />
material in the chemical industry for<br />
many years. According to the VCI, hydrogen<br />
is crucial here and forms the<br />
starting point of important chemical<br />
value chains. Already today, about<br />
12.5 billion cubic metres of hydrogen<br />
are used annually in Germany (according<br />
to vci.de).<br />
The town gas used in the past<br />
contained hydrogen up to around<br />
50 %. Hydrogen is not chemically aggressive<br />
and does not attack the usual<br />
fibre, graphite and PTFE sealing<br />
materials used.<br />
Ample proof of our strong familiarity<br />
with the medium and the fact<br />
we have long been successfully implementing<br />
corresponding sealing<br />
strategies.<br />
A look at the potential dangers<br />
of hydrogen<br />
As with all fuel gases, there is also a<br />
risk of unintentional combustion in<br />
the form of an explosion with hydrogen.<br />
And here, the explosion limits<br />
of the various fuel gases must be<br />
observed. The lower explosion limit<br />
(LEL) in air is 4 vol% for hydrogen and<br />
4.4 vol% for methane - which resembles<br />
the figures just mentioned. The<br />
upper explosion limits, however, at<br />
77 vol% H 2<br />
and 16.5 vol% CH 4<br />
are<br />
poles apart.<br />
Within CEN/TC 58 - Safety and<br />
control devices for Burners and appliances<br />
burning gaseous or liquid<br />
fuels - there is working group 15,<br />
which handles the subject of hydrogen<br />
and prepares information for international<br />
standardisation. Among<br />
other things, the “CEN/TC 58 WG 15<br />
evaluations 2022-04-14” presentation<br />
deals with a comparison of fuel<br />
gases methane, propane and butane<br />
with hydrogen and hydrogen/natural<br />
gas mixtures 20 % to 80 % with a view<br />
to gas installation equipment. Gas fixtures<br />
installed, like heating system<br />
burners, appliances and household<br />
devices, offer wide-ranging potential<br />
for future hydrogen applications.<br />
With all this in mind, the working<br />
group performed a hazard assessment,<br />
the scope of which included extensive<br />
calculations and initial measurements<br />
to get a clear picture.<br />
The danger from combustible<br />
gases is influenced not only by their<br />
leakage behaviour but also their<br />
ignit ability. So the working group assessed<br />
such influences and described<br />
them mathematically. Clearly, although<br />
the hazard potential of hydrogen<br />
exceeds that of natural gas<br />
(methane), it remains well below that<br />
of propane and butane.<br />
Conclusion<br />
1. We have positive experience with<br />
our well-known and high-quality<br />
fibre-based gaskets sealing materials<br />
from a history of safe sealing of hydrogen.<br />
2. Independent leakage measurements<br />
also show that we are within<br />
the usual ranges for fuel gases with<br />
hydrogen.<br />
3. And with the potential explosion<br />
hazard in mind, our experience with<br />
hydrogen underlines our progress<br />
within a familiar framework that<br />
has been safely controlled for many<br />
years.<br />
In sum, therefore, we see no need<br />
to fear hydrogen as a future carbon-<br />
free energy carrier. Contingent<br />
on appropriate design and having<br />
professionals in to install, hydrogen<br />
can be a safe means of achieving decarbonisation.<br />
The hydrogen age is<br />
on the horizon!<br />

blowers and compressors from<br />
Aerzen for the pneumatic conveying<br />
of its raw materials and products for<br />
more than 50 years. The packages<br />
provide absolutely oil- and absorption<br />
material-free air and guarantee<br />
a safe, reliable material flow. Service<br />

in every respect.<br />
Whether oat flakes, apricot kernels<br />
or bran: when it comes to the production,<br />

A+S BioTec GmbH. The family-owned<br />
company with headquarters in Völklingen,<br />
Saarland, specialises in grinding,<br />
drying, sieving, mixing, roasting<br />

leading companies in this branch.<br />
The company also makes no compromises<br />
when it comes to blower technology<br />
and has relied on the robust<br />

for over 50 years. Approximately 40<br />
positive displacement blowers and<br />

was founded as a milling company in<br />
1892. The company looks back on a<br />
long tradition, is characterised by innovations<br />
and is still family-owned<br />
today. In the meantime, the fifth generation<br />
has been steering the fortunes<br />
of the traditional company.<br />

locations around the globe.<br />
In Völklingen, the focus is still on<br />
mill technology. The core areas here<br />
are on comminution as well as mixing<br />
and drying. The spectrum ranges<br />
from powdered raw materials to fermented<br />
or thermally treated to protein-enriched<br />

From the delivery of the raw material<br />

steps and sometimes have to travel<br />
long distances for this. For example,<br />

“We produce 24 hours a day, five<br />
days a week. This is why we need 100<br />
per cent machine availability,” emphasises<br />
the Technical Manager at<br />
the Völklingen site. Reliability has top<br />
priority, and so has low downtime.<br />
“For this reason, we have been using<br />
blowers from Aerzen exclusively for<br />
more than 50 years. These machines<br />
are powerful, robust, need only little<br />
maintenance and are durable. It just<br />
fits nicely,” he says and adds: “What<br />
I particularly appreciate about the<br />
supplier is the availability of the employees.<br />
When the going gets tough,<br />
we have a contact person available<br />
at all times. A great product and a<br />
great team.”<br />

Positive displacement blowers are<br />

Fig. 4: Via the bent silver pipe, the end product enters the pre-silo for bagging<br />
The proverbial reliability of the positive<br />
displacement blowers has its reason:<br />
All core components itself, from<br />
the package to the control system,<br />
are manufactured in-house. In doing<br />
so, the family business attaches great<br />
importance to quality and sustainability.<br />
Only high-quality materials are<br />
used for the production. The development,<br />
production, distribution, assembly<br />
and maintenance of the company’s<br />
products as well as the quality<br />
management system have been certified<br />
several times. In 1868, the familyowned<br />
company from Lower Saxony<br />
brought Europe’s first positive displacement<br />
blower onto the market.<br />
floors until it reaches the pre-silo for<br />
grinding under the roof. Even the<br />
transport after grinding to the bagging<br />
plant, where the filling into 25 kg<br />
bags or big bags takes place, is not<br />
exactly a stone’s throw. This is where<br />
the positive displacement blowers<br />
from the specialists in Aerzen come<br />
into play. The approximately 40 positive<br />
displacement blowers provide<br />
air which is absolutely free of oil<br />
and absorption material. With volume<br />
flows between 3 and 20 m³/min,<br />
a conveying speed of 25 to 30 m/s<br />
and a conveying pressure of 300 to<br />
500 mbar, they ensure efficient, gentle<br />
and reliable transport of the sensitive<br />
bulk materials.<br />

These stages and packages are now<br />
among the most successful compressors<br />
ever.<br />
First choice for generating pneumatic<br />
conveying air<br />
The positive displacement blowers<br />
are characterised by high efficiency,<br />
low maintenance costs, reduced lifecycle<br />
costs, compactness as well as<br />
easy handling. They are considered<br />
the first choice for generating pneumatic<br />
conveying air due to their high<br />
quality and reliability. These blowers<br />
achieve intake volume flows between<br />
30 and 15,000 m³/h with a control<br />
range of 25 % to 100 % and conveying<br />
pressures of up to 1 bar positive<br />
pressure or differential pressures of<br />
up to 1,000 mbar(g). The drive concept<br />
with belt drive enables optimum<br />
volume flow design, and subsequent<br />
power adjustments can also<br />
be implemented quickly and easily.<br />
A+S BioTec GmbH and its production<br />
facility use this flexibility in order to<br />
react in a fast and easy way to customers’<br />
needs.<br />
The blower specialist is ISO<br />
22000 certified, guarantees oil-free<br />
operation according to ISO 8573-1,<br />
class 0 and trusts in silencers without<br />
absorption material. This means<br />
that the machines meet the highest<br />
food safety requirements and guarantee<br />
100 % product purity. The process<br />
air is guaranteed free of impurities<br />
such as oil, abrasion or insulation<br />
material.<br />
In addition to the 40 positive displacement<br />
blowers, the Saarland<br />
company also uses two VML screw<br />
compressors with start unloading<br />
device. The single stage packages<br />
can overcome a differential pressure<br />
Fig. 6: Two VML screw compressors are<br />
used to unload the trucks<br />
of 3,500 mbar and are thus the perfect<br />
choice for unloading the delivering<br />
silo vehicles high up into the silos.<br />
Annual maintenance guarantees<br />
optimum availability<br />
The supplier has been manufacturing<br />
quality products for over 150<br />
years and is today one of the world’s<br />
leading application specialists in the<br />
conveying and compression of gases.<br />
The high level of customer orientation<br />
is not only reflected in the product<br />
portfolio, but also in the range<br />
of services. Thanks to bespoke offers<br />
for every phase of the machines’<br />
lives, the specialist supports its customers<br />
in the maintenance and servicing<br />
of their packages. Abel+Schäfer<br />
at the Völklingen site also likes to rely<br />
on the know-how of the service technicians<br />
and has all blowers and compressors<br />
inspected thoroughly once<br />
a year. The maintenance work in-<br />
cludes, among other things, changing<br />
the oil, changing the suction filter<br />
and replacing the components for the<br />
power transmission (V-belts, clamping<br />
bushes). The condition of the<br />
packages is also examined and possible<br />
need for repair is determined.<br />
“The maintenance contract is a great<br />
advantage for us. This allows us to<br />
concentrate on our core tasks and at<br />
the same time benefit from optimal<br />
availabili ty,” the Technical Manager<br />
makes clear and is pleased: “Since we<br />
have had the maintenance contract -<br />
that is, for about ten years - there has<br />
not been a single machine failure.”<br />
Relying on the proven<br />
A+S BioTec GmbH is at home in the<br />
food world, but also produces for the<br />
cosmetics and technology industries.<br />
And the tendency is increasing, because<br />
natural, plant-based materials<br />
- as they are exclusively processed in<br />
Völklingen - are in vogue. For example,<br />
specially processed flour is needed for<br />
glue production, crushed grain husks<br />
for plastic profiles or ground apricot<br />
kernels for face and body scrubs.<br />
New fields of application, new<br />
methods, new processes: The company<br />
adapts to the requirements of<br />
its customers. One thing, however,<br />
will not change in the near future:<br />
the blower technology for pneumatic<br />
conveying comes from the supplier<br />
from Aerzen, which is considered to<br />
be well supplied all around.<br />

standstills mean sales losses. Due<br />
to more complex production systems<br />
and increasingly rigorous requirements<br />
for specific operator<br />
know-how, support from digital<br />
monitoring and analysis systems is<br />
necessary now in order to remain<br />
competitive in the future.<br />
1. Diaphragm metering pump<br />
trends in the process industry<br />
Pumps are often primary units in<br />
the process industry. Diaphragm<br />
metering pumps are particularly<br />
used in critical processes. The trouble-free<br />
and efficient operation of<br />
the installed pumps is crucial for a<br />
safe and profitable plant.<br />
The major driver of innovation<br />
in the process industry is digitalization<br />
– and it doesn’t stop at pumps.<br />
It is true that a diaphragm metering<br />
pump is initially a mechanical product<br />
and, with proper maintenance,<br />
it is also quite durable and troublefree.<br />
Nevertheless, continuous operational<br />
monitoring is necessary<br />
in order to detect process deviations<br />
and damage in time. In addition,<br />
the requirements for energy<br />
efficiency and safety are becoming<br />
more stringent.<br />
As a result, various trends are<br />
visible in numerous companies:<br />
Smart Factory<br />
The process industry is in the<br />
middle of a digital transformation.<br />
Factories are becoming increasingly<br />
networked and data exchange both<br />
within and between process chains<br />
is increasing. Since pumps are often<br />
operation-criti cal units but few have<br />
a digital moni toring system, there is<br />
neither data nor characteristic values<br />
for many processes. Many operators<br />
use their pump based on experience<br />
and follow cyclical or reactive<br />
maintenance strategies.<br />
System complexity<br />
The complexity of production systems<br />
is continuously increasing.<br />
This is related to the requirements<br />
for quality and process reliability, as<br />
well as to the general digitalization of<br />
many production facilities.<br />
Know-how<br />
The changes in the labor market also<br />
impact the day-to-day operations in<br />
the process industry. More and more<br />
experienced employees are retiring,<br />
turnover is rising and specific process<br />
and plant knowledge is declining.<br />
For this reason, many operators<br />
are increasingly turning to digital<br />
monitoring and support systems.<br />
Safety and environmental<br />
requirements<br />
The requirements for operational<br />
safety are increasing, and characteristic<br />
values that reflect the ecological<br />
footprint of production are taking<br />
on greater importance. The comprehensive<br />
environmental report has<br />
long been more than a marketing<br />
gimmick for companies. For investors,<br />
authorities and employees, it<br />
is an essential factor for evaluation,<br />
auditing or personal identification.<br />
Energy management<br />
The transformation in the energy<br />
sector directly affects the process industry.<br />
Pumps in the process industry<br />
often run 24/7 and are thus major<br />
consumers of energy. Optimizing<br />
their efficiency can have a significant<br />
impact on the energy efficiency of<br />
the entire plant. But here, too, evaluation<br />
requires characteristic values.<br />
2. Pump monitoring requirements<br />
Based on the trends in the process industry,<br />
various focal points can be derived<br />
for monitoring systems for diaphragm<br />
metering pumps.<br />
Condition monitoring and<br />
predication<br />
First of all, the operating states of the<br />
pump must be monitored and deviations<br />
from target values must be detected<br />
in good time. In the process,<br />
various parts of the pump must be<br />
monitored in a specific context:<br />
– Drive unit<br />
– Hydraulic system<br />
– Pump head<br />
– Valves<br />
System monitoring<br />
Within the plant, the pump can be<br />
used as a sensor for the complete<br />
system. With diagnostics collected<br />
in the pump, it is possible to derive<br />
statements about the system status:<br />
– Piping suction side<br />
– Piping pressure side<br />
– Pulsation<br />
– Flow rate<br />
– Fluid state<br />
Energy management and efficiency<br />
By measuring incoming energy<br />
and hydraulic power, it is not only<br />
possible to determine efficiency and<br />
CO 2<br />
balance, but also to diagnose material-related<br />
signs of wear.<br />
– Efficiency<br />
– CO 2<br />
balance<br />
– Load collectives<br />

data analysis for new and existing<br />
pumps. The system determines<br />
characteristic values and key performance<br />
indicators. There is no process<br />
control intervention or direct<br />
contact between the sensor system<br />
and the conveyed fluid.<br />
With parameter-based condition<br />
monitoring, operators detect<br />
and monitor their pumps proactively.<br />
They can also optimize the overall<br />
output and robustness of their<br />
pump and piping systems. This increases<br />
the efficiency of their entire<br />
production plant.<br />
Characteristic value determination<br />
is based on recording measured<br />
variables such as structure-borne<br />
noise, hydraulic pressure and trigger.<br />
To get results, 2,000 signals per<br />
pump head are processed per second.<br />
These signals are recorded by<br />
the connected PLC.<br />
The characteristic values and diagnoses<br />
are output and transmitted<br />
via various interfaces. The IPC has a<br />
web-based interface for making settings<br />
and visualizing the determined<br />
characteristic values and diagnoses.<br />
An OPC UA server is provided for<br />
transmission to a control center.<br />
In addition, characteristic values<br />
and diagnoses can be transmitted<br />
to the LEWA cloud and the customer<br />
portal via an Internet connection.<br />

precisely. Analyzing the individual<br />

the structure-borne noise has increased<br />
in the second pump head (B)<br />
(Cf. Fig. 6). In this case, the Smart<br />
Monitoring System issues a plain text<br />
message about the valve wear that<br />
is occurring and also indicates which<br />

Conclusion<br />
Valve monitoring not only enables<br />
valve wear to be measured before it<br />
affects plant operation. It also makes<br />
the exact localization of the affected<br />
valves possible. This creates the basis<br />
for targeted, condition-oriented and<br />
predictive maintenance.<br />
7. Prevent diaphragm ruptures<br />
Fig. 6: Structure-borne noise measurement<br />
across all pump heads<br />
Diaphragm ruptures are always critical<br />
for diaphragm metering pumps<br />
and lead to immediate process interruption.<br />
Since diaphragm ruptures<br />
can have various causes, prevention<br />
is difficult. While diaphragm ruptures<br />
due to foreign bodies in the fluid or<br />
wear cannot be predicted, hydraulically<br />
induced diaphragm ruptures are<br />
easy to identify in certain operating<br />
situations.<br />
The Smart Monitoring System<br />
determines the length of the “snifting<br />
phase” (leak supplement phase)<br />
for various diagnoses. In the sniffing<br />
phase, the hydraulic oil lost during<br />
the pressure phase due to internal<br />
leakage in the pump head is replenished.<br />
When the length of the sniffing<br />
phase (t 1<br />
) decreases, a condition develops<br />
that leads to diaphragm rupture<br />
(t 2<br />
) (Cf. Fig. 7). The system issues<br />
a warning when the sniffing phase<br />
can no longer be measured. In many<br />
cases, operators can see in good time<br />
when a hydraulically induced diaphragm<br />
rupture is imminent and can<br />
react accordingly.<br />
Fig. 7: Measurement of the sniffing phase<br />
at the pump head<br />
Conclusion<br />
Monitoring pump hydraulics enables<br />
undesirable conditions to be detected<br />
in good time and prevents hydraulically<br />
induced diaphragm ruptures.<br />
Monitoring makes controlled shutdown<br />
and maintenance possible.<br />
8. Avoid pulsations in the piping<br />
Piping and pulsation dampers are<br />
often subject to the inherent vibrations<br />
of the system, which can develop<br />
into pulsation shocks. These<br />
shocks not only endanger the process,<br />
but are also a safety risk. Monitoring<br />
the pump also simultaneously<br />
enables the vibration behavior of the<br />
peripher al systems to be monitored.<br />
Figure 8 shows a peak of the pressure-side<br />
pulsation in the piping, the<br />
“coupling pressure pulsation” (t 1<br />
). At<br />
the same time, the discharge pressure<br />
of the pump is constant during<br />

the same period. This means that<br />
pulsation cannot be detected in the<br />
opera tor's process control system by<br />
measuring the flow rate. The Smart<br />
Monitoring System issues warning<br />
messages when the coupling pressure<br />
pulsation exceeds the limit values.<br />
This enables operators to see in<br />
good time when pulsation impacts<br />
occur in the piping, even if the process<br />
control system measures a constant<br />
flow rate.<br />
Fig. 8: Coupling pressure pulsation and discharge<br />
pressure in the same time period<br />
Conclusion<br />
Monitoring the piping enables pulsation<br />
shocks to be detected. The characteristic<br />
values are a reliable indicator<br />
of the condition of the piping<br />
system and can be used as the basis<br />
for optimizing pulsation dampers.<br />
9. Detecting and preventing drive<br />
unit damage in good time<br />
Drive unit damage in diaphragm metering<br />
pumps is rare, but usually the<br />
result of bearing wear. Active bearing<br />
monitoring in the drive unit using<br />
sensors is complex and costly. For this<br />
reason, indirect bearing monitoring is<br />
easier to implement and is a good basis<br />
for diagnostics and prediction.<br />
In this case, passive bearing monitoring<br />
means that the bearing itself<br />
is not monitored. Instead, the energy<br />
input into the pump is set in relation<br />
to its hydraulic power. If the ratio<br />
deteriorates, there is a loss of energy<br />
due to heat input into the system.<br />
This is usually a sign of unwanted friction<br />
due to bearing wear, which in<br />
this case is detected at an early stage.<br />
Subsequent damage due to damaged<br />
bearings can be prevented by timely<br />
shutdown and maintenance.<br />
Figure 9 shows the efficiency<br />
of the drive unit and the hydraulic<br />
power of the pump. It shows that the<br />
efficiency of the drive unit decreases<br />
while the hydraulic efficiency remains<br />
the same. This means that the<br />
pump requires more energy to provide<br />
the same hydraulic power. This<br />
indicates that there is a loss of energy<br />
Fig. 9: Drive unit efficiency and hydraulic<br />
efficiency<br />
in the system – usually due to frictional<br />
heat. The Smart Monitoring System<br />
informs operators with a warning<br />
that the relative efficiency has fallen<br />
below a limit value. This leaves time<br />
for a drive unit inspection before subsequent<br />
damage from a damaged<br />
bearing occurs, which can have farreaching<br />
consequences.<br />
Conclusion<br />
With the indirect monitoring of bearings<br />
via the energy balance, the Smart<br />
Monitoring System offers an efficient<br />
and reliable alternative to sensorbased<br />
bearing monitoring.<br />
10. Overall conclusion<br />
Smart Monitoring is a comprehensive<br />
condition monitoring and prediction<br />
system that process plants‘ operators<br />
can use to increase availability<br />
and operational safety. The system<br />
also makes a valuable contribution<br />
in other areas of application such as<br />
energy management and KPI-based<br />
production optimization.<br />

Automatic adjustable pump makes<br />

Intelligent pump technology facilitates more sustainable<br />
operation at WWTP in Gelsenkirchen, Germany<br />
It's all a matter of adjustment:<br />
Municipal water supply is experiencing<br />
a smooth transition into the<br />
digital age and is becoming more<br />
sustainable. Intelligent pump technology<br />
from SEEPEX makes them<br />
fit for the future. One of the world’s<br />
leading specialists in progressive<br />
cavity pumps, pump systems and<br />
digital solutions was able to solve<br />
various technical challenges and<br />
help save time as well as energy in<br />
a municipal WWTP. The special feature<br />
of the pump is the digitally<br />
monitored, automated adjustment<br />
of the pumping elements. The SCT<br />

service life, leads to lower energy<br />
and resource consumption, increases<br />
operational reliability and process<br />
efficiency, and reduces maintenance<br />
requirements.<br />

Saving energy, preserving resources,<br />
in short: sustainable behavior is<br />
on everyone’s mind. This applies, in<br />
particular, to the field of environmental<br />
technology. The German Federal<br />
Environment Agency, for example,<br />

Fig. 1: SCT AutoAdjust - The progressive cavity pump with automatic stator clamping.<br />
Hydraulically adjustable and highly precise all at the touch of a button.<br />
high power consumption are “the<br />
continuously running pumps.” “With<br />
the automated progressive cavity<br />
pump, SEEPEX has been able to demonstrate,<br />
using the Gelsenkirchen<br />
WWTP as an example, that the investment<br />
in the new technology pays<br />
off both economically and for the<br />
climate,” says the Head of Product<br />
Mana gement, giving a positive summary<br />
after two years.<br />
Requirements placed on modern<br />
pump technology are getting more<br />
demanding in many places. The project<br />
at the WWTP in Gelsenkirchen<br />
demonstrates how the efficiency<br />
of conveying and processing highly<br />
abrasive sewage sludge can be fur-<br />

Intelligent pump technology<br />
ther improved. The high viscosity of<br />
the sewage sludge and the highly<br />
abrasive dry matter content - in this<br />
case of around 3 to 4 percent at a<br />
flow rate of 5 to 7 m³/h and 2 to 6 bar<br />
back pressure - have an increasing<br />
effect on energy requirements and<br />
wear, making it a demanding conveying<br />
task.<br />
In the past, the pump’s performance<br />
decreased over time because<br />
the stator and rotor - as in many sewage<br />
treatment plants - are subject<br />
to high abrasive wear. At constant<br />
speed, wear becomes noticeable in<br />
a steadily accelerating decrease in<br />
flow rate. The reduced flow rate can<br />
be compensated for by increasing the<br />
speed. However, this leads to an increased<br />
energy demand of the pump<br />
and an exponential increase in the<br />
wear rate. In addition to increased<br />
operating costs, this leads to a shortened<br />
rotor and stator life, increased<br />
downtime, more resource requirements<br />
and higher costs for spare<br />
parts and maintenance.<br />
Perfect operating point at the<br />
push of a button<br />
As part of the municipal water management<br />
system, the WWTP in the<br />
north of the city is responsible for<br />
treating the wastewater of a population<br />
of more than 57,000 in this region.<br />
The pump manufacturer from<br />
Bottrop replaced its standard progressing<br />
cavity pump, previously<br />
used here in discontinuous operation,<br />
with state-of-the-art technology.<br />
Fig. 3: The flow rate per rotor revolution is scaled to the set point or optimal operating point.<br />
100 % stands for the optimal required operating point of the pump. The pump should run<br />
between 80 % and 100 % (green area) due to normal operating conditions.<br />
“The auto mated pump combines a<br />
new type of hydraulic adjustment unit<br />
with simultaneous digital moni toring<br />
and control, making it the world’s first<br />
progressive cavity pump that automatically<br />
(Auto) adjusts its operating<br />
point (Adjust) at the push of a button,”<br />
says the Head of Product Management,<br />
explaining the prin ciple. In<br />
this way, it can compensate for any<br />
wear that occurs and always operates<br />
at maximum efficiency at the<br />
optimum operating point. The new<br />
technology made it possible by using<br />
a smaller sized pump, including a less<br />
energy consuming drive than before,<br />
resulting in lower costs in terms of resources<br />
and energy.<br />
Real-time data at a glance<br />
The modern pump can be operated<br />
from the control room, on a tablet<br />
or smartphone. Long distances for<br />
control and maintenance are a thing<br />
of the past. The SCT AutoAdjust is<br />
equipped with an innovative hydraulic<br />
adjustment unit with associated<br />
sensor technology which, together<br />
with the digital connection of the<br />
pump (Pump Monitoring and Connected<br />
Services), enables automated<br />
adjustment of the stator clamping.<br />
The stator clamping is performancedetermining<br />
for the operation of the<br />
pump and can now always be optimally<br />
adjusted to the operating conditions.<br />
The digital connection is established<br />
via sensors, which record important<br />
parameters such as flow rate,<br />
pressure, rotor speed or temperature<br />
in real time and analyzes them in<br />
Connected Services using modern algorithms<br />
and artificial intelligence. In<br />
this way, the operating status of the<br />

The pump manufacturer from Bottrop has continuously optimized its Smart Conveying<br />
<strong>Technology</strong> (SCT) since 2008. The proven design principle: the Smart Stator consists<br />
of two halves, which makes maintenance very easy, without removing suction or discharge<br />
lines. An integrated re-tensioning device ensures that the clamping between<br />
the rotor and stator can be adjusted for optimum conveying if the flow rate is reduced,<br />
for example, due to wear. This significantly extends the service life of the rotor and<br />
stator, reduces the need for spare parts, and lowers the life cycle costs of pumps -<br />
while maximizing energy yield.<br />
Digital Solutions provide real-time information<br />
To ensure that the pump is always in top shape, SEEPEX uses its Digital Solutions in<br />
numerous applications. The digital solutions are in alignment with the requirements<br />
of the industrial era 4.0 in which intelligent and interconnected machines exchange<br />
information directly with each other in real time. In addition to Pump Monitoring and<br />
Connected Services, the supplier has developed other products that provide users<br />
with important data and derived information about operations. The added value for<br />
customers lies in tailored solutions, simpler processes and greater transparency. The<br />
focus here is on improved know-how about the performance of the pumps and lower<br />
maintenance costs thanks to optimized operation.<br />
In addition to remote monitoring via Connected Services, apps are also available for<br />
service and maintenance. These include a remote monitoring package, the Advanced<br />
Analytics package for process optimization, and tool interfaces for transferring data<br />
and operating parameters. The free maintenance app offers step-by-step instructions<br />
and 3-D animations. In a logbook, the maintenance history of the pump as well as the<br />
respective status is noted and the location is clearly displayed. Users can also track operating<br />
parameters such as speed, flow rate and current consumption in the logbook,<br />
so that they have all the necessary data at hand for optimal readjustment of the rotor/<br />
stator clamping. The Service Point app supports uncomplicated spare parts procurement.<br />
Simply scan the QR code on the nameplate of the pump and various help functions<br />
and important data are available at the virtual Service Point. Suitable spare parts<br />
can be ordered easily. The operating instructions for the progressive cavity pump are<br />

As a result, pumping efficiency<br />
has increased by 20 percent with a<br />
reduced pump size compared to the<br />
predecessor pump, which consumes<br />
less energy. Our innovation has<br />
demonstrated its great potential and<br />

of abrasive sewage sludge at<br />
the Gelsenkirchen WWTP. As part of<br />
the plant, it makes an important contribution<br />
to sustainable, reliable and<br />

Water management benefits from<br />
innovative technology<br />
The more efficient use of resources<br />
on the one hand and the use of digital,<br />
intelligent technology on the<br />
other have long become a central issue<br />
in municipal environmental technology.<br />
For example, the German<br />
Association of Water, Wastewater<br />
and Waste (DWA) states in a position<br />
paper: “Digitalization affects all areas<br />
of water management, from planning<br />
tools and plant technology to staff<br />
training standards and use by the<br />
public. In this context, the automation<br />
and networking of water management<br />
plants, for example, has been<br />
standard practice for a long time. Extremely<br />

Bredel industrial hose pumps convey<br />
corrosive media in flue gas purification<br />
Bredel hose pumps, a brand of<br />
Watson-Marlow Fluid <strong>Technology</strong><br />
Solutions, offer a powerful and reliable<br />
solution for many pumping<br />
tasks in energy-from-waste plants.<br />
In the AVA Velsen waste treatment<br />
plant, the pumps were able to prove<br />
their suitability in the processing<br />
of corrosive and abrasive media in<br />
several process stages of flue gas<br />
purification. In the process, they<br />
offer longer service life and lower<br />
costs than the centrifugal and rotary<br />
lobe pumps previously used.<br />
The Zweckverband Entsorgungsverband<br />
Saar (EVS) is an association of all<br />
52 municipalities in the German state<br />
of Saarland. EVS is responsible for regional<br />
wastewater treatment and environmentally<br />
sound waste disposal<br />
throughout the state. The non-recyclable<br />
waste, especially a large part of<br />
the residual waste and commercial<br />
waste, is thermally recycled in the<br />
waste incineration plant AVA Velsen.<br />
In total, about 255,000 tonnes of<br />
residual waste are thermally recycled<br />
annually in AVA Velsen, generating<br />
about 150,000 MWh of electricity.<br />
This is achieved by optimised waste<br />
allocation and low-fault operation,<br />
based on the consistent use of modern<br />
and reliable technologies.<br />
Hose pumps in the flue gas<br />
cleaning system<br />
The flue gases produced during waste<br />
incineration are fed into a multi-stage<br />
flue gas cleaning system to remove<br />
pollutants. For flue gas scrubbing,<br />
the gas is first cooled in the so-called<br />
quench, by intensive spraying with<br />
water, which flushes out the first pollutants.<br />
The contaminated wash water<br />
(“quench water”) is later subjected<br />
to further treatment steps to precipitate<br />
and filter out more pollutants.<br />
Initially, several centrifugal pumps<br />
were used throughout the plant to<br />
transport the wash water. Since the<br />
wash water is very acidic (pH 0) and<br />
highly corrosive, these pumps repeatedly<br />
broke down: The mechanical<br />
seals of the centrifugal pumps<br />
proved to be especially susceptible to<br />
damage and had to be replaced frequently,<br />
reports the team leader of<br />
AVA Velsen GmbH responsible for the<br />
wastewater treatment and evaporation<br />
plant. In many cases, the damage<br />
even proved so serious that the<br />
entire pump head of the centrifugal<br />
pumps had to be replaced - with considerable<br />
costs for spare parts and<br />
downtime.<br />
Pumping without seals and valves<br />
AVA Velsen GmbH found a solution<br />
to these problems in the hose pumps<br />
from the supplier. These pumps require<br />
neither seals nor other additional<br />
equipment such as ball check<br />
valves, diaphragms, immersed rotors,<br />
stators or pistons, which can<br />
leak, clog or corrode and then have<br />
to be replaced at great expense. No<br />
moving pump components come into<br />
contact with the medium.<br />
The only spare part in the hose<br />
pumps is the precision-manufactured<br />
hose element. Depending on the application<br />
and purpose, it is available<br />
in a variety of different materials, including<br />
EPDM, which offers excellent<br />
resistance to aggressive chemicals<br />
and concentrated acids.<br />
A total of four centrifugal pumps<br />
in the wastewater treatment plant<br />
were replaced with industrial hose<br />
pumps. With great success: The service<br />
life of the EPDM hose elements<br />
enabled total costs to be reduced<br />
by more than 50 percent compared<br />
to the previously used centrifugal<br />
pumps.<br />

The industrial peristaltic pumps have<br />
already been able to prove their suitability<br />
for difficult and demanding<br />
pumping applications in another application<br />
at AVA Velsen: During a subsequent<br />
process step, limestone slurry<br />
(“milk of lime”) is added to the wash<br />

Fig. 2: Industrial hose pump for pumping very<br />
acidic (pH value 0) and corrosive washing water.<br />
Since only the hose elements made of EPDM<br />
touch the aggressive medium, it offers a long<br />
service life.<br />
water in a treatment plant, thus enabling<br />
the sulphur dioxide to be filtered off in the<br />
form of gypsum. A rotary lobe pump was<br />
initially used to transport the limestone<br />
slurry. Due to the abrasive character and<br />
relatively high solids content of the limestone<br />
slurry, this pump proved to be very<br />
susceptible to breakdowns and caused<br />
high repair and downtime costs. The solution<br />
here was also a robust industrial<br />
Fig. 3: Pump to process lime slurry with a high<br />
solids content without any problems.<br />
Fig. 4: The direct-coupled design combines the<br />
reliability of the long-coupled design with the advantages<br />
of the compact close-coupled design.<br />
hose pump from the manufacturer. The<br />
pump now delivers the milk of lime with<br />
a high degree of reliability. The hose elements<br />
used achieve a service life of about<br />
nine months, reports the team leader. For<br />
safety reasons, however, the hose element<br />
is replaced every six months as part<br />
of planned maintenance. The costs for this<br />
are very low compared to the repair costs<br />
of the rotary lobe pump and moreover, the<br />
replacement of peristaltic hose elements<br />
can be carried out quickly and easily onsite.<br />
For these reasons, the hose pumps in<br />
various sizes are now also used in the AVA<br />
Velsen for pumping a saturated NaCl solution<br />
as well as filtrates.<br />
As the pumps are exposed to a corrosive<br />
atmosphere, the components have<br />
been made of stainless steel wherever possible.<br />
The pumps are also painted according<br />
to the C4 painting standard or are protected<br />
with a double layer of paint. More over,<br />
the pump manufacturer offers pumps<br />
with a paint-free, galvanically coated pump<br />
housing for aggressive atmospheres.<br />
Ideal solution for many applications in<br />
energy-from-waste plants<br />
At various application at AVA Velsen, the<br />
pumps are demonstrating the numerous<br />
advantages of peristaltic hose pumps for<br />
processing aggressive or abrasive pumped<br />
media: They offer a suction head of up to<br />
9.5 metres, are self-priming and offer good<br />
dry-running capabilities. Without internal<br />
seals or valves, no moving parts come<br />
into contact with the medium, and they<br />
impress with their high reliability and low<br />
maintenance requirements.<br />
Maximum reliability is also ensured by<br />
the manufacturers patented direct-coupling<br />
technology: it combines the reliability<br />
of the long-coupled design with the advantages<br />
of the compact close-coupled design:<br />
An innovative buffer zone protects the<br />
gearbox, bearings and pump head in case<br />
of leakage. Heavy-duty pump rotor bearings<br />
support the radial load, so the drive<br />
shaft transmits only the torque and speed<br />
needed for the specific application.<br />
Depending on the pump model and<br />
size, the hose pumps offer a high flow<br />
rate of up to 108,000 litres at a pressure<br />
of up to 16 bar and convey abrasive slurries,<br />
pastes and viscous media with up to<br />
80 percent solids content with 100 percent<br />
volumetric accuracy.<br />
Therefore, the supplier’s peristaltic<br />
pumps are the first choice for many applications<br />
in the environmental and energy<br />
industries. In these industries, they are<br />
used wherever corrosive, viscous, abrasive<br />
or other difficult-to-handle media<br />

The heart of every industrial hose<br />
pump is the hose element. It is not<br />
only the single wearing part, but also<br />
the only component on the entire<br />
pump that comes into contact with<br />
the fluid. Only a perfect match of<br />
pump and hose element offers maximum<br />
reliability and performance: As<br />
one of few pump manufacturers, the<br />
supplier has its own production of<br />
high-performance hose elements -<br />
especially and exclusively for use with<br />
its own peristaltic pumps.<br />
Unlike many hoses from other<br />
manufacturers, the hose elements<br />
are precision-engineered. This means<br />
that only the highest quality rubber<br />
compounds are used, reinforced with<br />
several extruded layers of braided nylon,<br />
which ensure the automatic relaxing<br />
of the hose element and strong<br />
suction capabilities of the pump. As a<br />
result, the pump is self-priming and<br />
dry-running and can handle even high<br />
viscosity fluids with ease. Due to the<br />
extruded layers, the hose element offers<br />
higher strength and longer service<br />
life than hose elements with<br />
wrapped layers. The hose elements<br />
are ground to meet the tight tolerances<br />
in wall thickness thus providing<br />
maximum hose and pump life.<br />

60 % fewer production losses: Downhole<br />
progressing cavity pumps simplify replacment<br />
and reduce costs with special flush-by unit<br />
Pump service life is two to three times longer<br />
compared to previous models<br />
At one of Turkey’s largest and most<br />
productive oil fields, the BATMAN<br />
field in southeast Anatolia, different<br />
downhole progressing cavity<br />
pumps are used to pump a mixture<br />
of crude oil and water to the surface.<br />
To increase the service life of<br />
the pumps and to reduce the installation<br />
costs and the pump replacement<br />
time, the owners decided to<br />
test the use of insertable progressing<br />
cavity pumps. They chose the<br />
downhole variant of the proven<br />
progressing cavity pumps from<br />
the global manufacturer NETZSCH<br />
Pumpen & Systeme GmbH based in<br />
southern Germany. As all progressing<br />
cavity pumps, they use a special<br />
operating principle where a helical<br />
rotor rotates inside a fixed stator to<br />
form closed conveying chambers.<br />
These chambers continuously move<br />
the oil-and-water mixture to the delivery<br />
side with a consistent volumetric<br />
flow. While the efficiency of<br />
this system is between 40 and 70 %<br />
of the oil production maximum, the<br />
volumetric efficiency of a downhole<br />
progressing cavity pump reaches an<br />
impressive 75 to 95 % of the theoretically<br />
possible volume flow. Another<br />
essential advantage of the insertable<br />
pumps – three of which are<br />
now in use on the Turkish oil field –<br />
is that they are relatively easy to install<br />
directly in the conveying line. In<br />
addition, they can be replaced using<br />
a special flush-by unit without removing<br />
them from the pipe and uninstalling<br />
the well sensors. This significantly<br />
reduced the expenditures<br />
for workovers at the oil field, which<br />
minimised production losses by up<br />
to 60 per cent and significantly lowered<br />
costs. In addition to this, the<br />
Fig. 1: The Batı-Raman field in southeast Anatolia is one of the largest and most productive<br />
oil fields in Turkey. (Photo © : Adobe Stock/Inna)<br />
service life of the pumps is two to<br />
three times longer compared to the<br />
previously used conventional progressing<br />
cavity pumps.<br />
Various pump types from different<br />
manufacturers are used for pumping<br />
oil on the BATMAN field in Turkey,<br />
including NETZSCH standard downhole<br />
pumps. On this standard version,<br />
the stator is bolted to the tubing<br />
at the lowest point and, in a second<br />
step, the rotor is installed through<br />
the tubing together with the sucker<br />
rod. “To replace these pumps, however,<br />
they have to be removed together<br />
with the tubing in a complex<br />
process, which requires us to buy<br />
and use an expensive workover unit,”<br />
explains the Technical Support Engineer,<br />
Oil & Gas Upstream, NETZSCH<br />
Pumps and Systems Turkey. To lower<br />
rig costs and to shorten the pump<br />
replacement time, the owners therefore<br />
decided to use insertable down-<br />

hole progressing cavity pumps from<br />
the supplier. These pumps feature a<br />
very small outer diameter.<br />
Reliable pumping of<br />
multi-phase media<br />
Just like conventional progressing<br />
cavity pumps from the Bavarian supplier,<br />
these pumps are also based on<br />
a rotor that rotates in a geometrically<br />
adapted fixed stator in an oscillating<br />
motion. The precise geometry pairing<br />
produces conveying chambers during<br />
the rotation and the medium is gently<br />
transported in these chambers from<br />
the intake side to the delivery side.<br />
The chambers are closed, which not<br />
only prevents backflow but also ensures<br />
movement of the medium with<br />
stable volume and pressure so that<br />
no shear forces and hardly any pulsation<br />
occur. This is crucial because<br />
oil-and-water mixtures otherwise produce<br />
emulsification effects. These effects<br />
would make the subsequent<br />
separation of the mixtures at the surface<br />
much more difficult. This risk also<br />
exists for the medium that is pumped<br />
on the BATMAN field, because it consists<br />
of 25 % water and 75 % oil.<br />
The volumetric efficiency of the<br />
downhole progressing cavity pumps<br />
is between 75 and 95 % of the theoretically<br />
possible volume flow. While<br />
conventional pumping systems soon<br />
reach their limitations in the case of<br />
fluctuating consistencies, resulting<br />
in pumping interruptions, pressure<br />
loss, and material damage, the consistency<br />
and viscosity of the medium<br />
are irrelevant with this displacement<br />
technology. The pumps are therefore<br />
particularly suitable for difficult<br />
multi-phase media and can transport<br />
even highly viscous oils to the<br />
surface with over 50,000 mPas. The<br />
pumped volume is determined by<br />
the pump size and the speed of the<br />
unit, meaning it can be controlled<br />
with great precision. Another key feature<br />
of the downhole models based<br />
on the progressing cavity pump is the<br />
high level of flexibility with respect to<br />
the flow rate – it can be between 0.5<br />
and 475 m³/d. For the medium on the<br />
BATMAN field, which is pumped at<br />
60 °C with a pressure of 15 bar, the<br />
flow rate is 4.77 m³/d.<br />
Fig. 3: Like all progressing cavity pumps, they feature a special pumping principle where a<br />
helical rotor rotates in a fixed stator to form closed conveying chambers. These chambers<br />
move the oil-water mixture to the delivery side in a continuous, consistent volumetric flow.<br />

maintenance of the pump can be carried<br />
out with a special flush-by unit:<br />
The pump can be replaced with a rod<br />
pulling unit which is much less expensive<br />
than a workover unit.<br />
Installation directly in<br />
the tubing and replacement<br />
with rod pulling unit<br />
or the locking system. The installation<br />
is completed by lowering<br />
the pump until it reaches the<br />
nipple or the locking system once<br />
again and then securing it there<br />
with a friction anchor and an<br />
axial lock. Another advantage is<br />
that subsequent replacement or<br />
maintenance of the pump can be<br />
carried out with a special flush-by<br />
unit. The pump can be replaced<br />
with a rod pulling system which is<br />
much less expensive than a complex<br />
workover unit with special<br />
hydraulic tongs for bolting the<br />
tubing. Overall, this procedure<br />
can significantly reduce costs because<br />
the pump with the sucker<br />
rod can be removed through the<br />
tubing. The tubing, any well sensors,<br />
and the sensor cable do not<br />
have to be removed. This minimises<br />
the time required for the<br />
workover and reduces production<br />
losses by up to 60 %.<br />
The longer service life<br />
of the pumps<br />
World Class.<br />
The pumps used at the Anatolian<br />
oil field have other special<br />
features as well: They are insertable<br />
progressing cavity pumps<br />
designed with the main focus<br />
on minimising the costs for installation<br />
of the pumps in the<br />
well. The key feature of these<br />
pumps is therefore the installation<br />
through the tubing string.<br />
That means that the pump is not<br />
connected to the tubing, but installed<br />
directly inside it. The procedure<br />
is as follows: The pump<br />
is first lowered into the tubing<br />
string until the installation clamp<br />
reaches the wellhead and is then<br />
held by means of the pump rod.<br />
The installation clamp can then<br />
be removed and the sucker rod<br />
can be installed. The pump is<br />
subsequently lowered down to<br />
nipple N11 or the pump locking<br />
system N12 – one of these systems<br />
will have already been installed<br />
in the well beforehand.<br />
The engineers can then check the<br />
position of the pump by pulling<br />
the rod string upwards and releasing<br />
the pump from the nipple<br />
The first two models of these<br />
much easier-to-replace downhole<br />
pumps installed in the<br />
Turkish oilfield were so successful<br />
that a third model followed<br />
in the year after. “The purchaser<br />
is very satis fied with the result<br />
of this project because it<br />
not only reduced the plant costs<br />
but also increased the service<br />
life of the pumps,” summarises<br />
the Technical Support Engineer.<br />
“It is two to three times as<br />
long as the service life of conventional<br />
progressing cavity<br />
pumps from NETZSCH that are<br />
not installed inside the tubing.”<br />
The Bavarian pump manu-<br />
facturer also regards this as a<br />
highly successful project because<br />
this was the first time that insertable<br />
downhole progressing cavity<br />
pumps were used in Turkey.<br />

Energy savings potential with intelligent<br />

Energy crisis, 1.5 degree target, CO 2<br />
savings, science-based targets, water<br />
scarcity... these are all topics<br />
that we are currently encountering<br />
again and again. Turning down the<br />

for private households. But<br />
what are the possibilities for industry?<br />
How can water and energy consumption<br />
in the manufacturing sector<br />
be reduced?<br />
Many industrial applications like temperature<br />
control, water treatment<br />
and wash & clean are energy-intensive<br />
and consume a lot of water. And<br />
pumps always play a part. But at the<br />
same time, these areas offer relatively<br />
simple and quick ways on how to<br />
realise savings. Let’s take energy savings<br />
as an example, upgrading the<br />
current pump installation can pay<br />
for itself quite quickly due to the increased<br />
energy costs. How process<br />
optimisation can be realised in an<br />
existing plant is shown in the following<br />
example. The soft drink manufacturer<br />
Britvic is expecting ener gy savings of<br />
more than 430,000 € per year by investing<br />
in new pressure boosting<br />

of this includes the heating and cooling<br />
of water at its factory in Rugby, UK.<br />
The pump manufacturer<br />
Grundfos performed an Energy<br />

the actual energy use in the system.<br />
This is not simply a ‘nameplate’ check<br />
of efficiency; sensors are placed in<br />
Fig. 2: The Energy Check is a pump survey by the customer or a member of the pump<br />
supplier’s staff with subsequent analysis/calculation by the supplier<br />

Vacuum-based leak testing methods<br />
Vacuum-based methods for testing<br />
the packaging of pharmaceutical products<br />
for leaks<br />
Secure packaging of pharmaceutical products<br />
The quality and effectiveness of<br />
medicines depends to a significant<br />
extent on their proper packaging:<br />
Sterile products and medicines that<br />
are sensitive to moisture or oxygen<br />
must remain extremely well sealed<br />
throughout their entire shelf life to<br />
protect them from biological contamination<br />
and the ingress of water<br />
and oxygen. Otherwise, there may<br />
be serious consequences.<br />
The most important barrier for ensuring<br />
sufficient integrity of pharmaceutical<br />
products and for protecting<br />
them against harmful external influences<br />
is the so-called primary packaging.<br />
The most common types of<br />
primary packaging include plastic or<br />
glass bottles, vials and syringes, but<br />
also IV bags and blister packs.<br />
(1) Product development and<br />
process validation<br />
In the first part of the life cycle, the<br />
requirements for the primary packaging<br />
and the container closure system<br />
are defined. The goal is to define<br />
the minimum requirements for<br />
sealing. This includes testing using<br />
sensitive test methods such as helium<br />
leak detection. In the case of particularly<br />
sensitive products, such as<br />
sterile medicines, the so-called MALL<br />
(Maximum Allowable Leakage Limit)<br />
is checked, for example, which is defined<br />
in USP as < 0.2 μm de-<br />

directive divides the product life cycle defect size was determined in a study<br />
into three parts, each of which places by Kirsch, in which the microbial ingress<br />
failure rate was measured for<br />
different demands on the leak testing<br />
systems:<br />
various defect sizes. From a defect<br />
Fig. 1: Selection of common primary packaging used for pharmaceuticals.<br />
Necessity of leak detection<br />
The primary packaging must be subjected<br />
to leak tests at various times<br />
throughout the life cycle of the pharmaceutical<br />
product. The United<br />
States Pharmacopeia (USP), which is<br />
the government body responsible for<br />
standards and directives in the pharmaceutical<br />
industry in the USA, introduced<br />
a new directive in 2016: USP<br />
. This describes methods and<br />
procedures for the leak testing of<br />
pharmaceutical packaging and gives<br />
the user guidelines on how to evalu-<br />
size 0.2 μm onward, no microbial ingress<br />
can be detected. By means of<br />
a helium leak test, this value has also<br />
been quantitively determined with a<br />
gas flow measured in mbar*l/s. [1]<br />
(2) Product manufacturing<br />
The second step involves regular testing<br />
and monitoring of the quality of<br />
the chosen packaging during the production<br />
process. Here, random inspections<br />
are often performed, but<br />
also 100-percent checking of the containers.<br />
Since sterility has already<br />
been demonstrated during product<br />

development, the chosen methods<br />
prioritize faster testing times rather<br />
than higher sensitivity.<br />
(3) Assessment of the<br />
commercial shelf life<br />
Integrity tests are then carried out on<br />
a sufficient number of samples during<br />
various periods throughout the<br />
entire shelf life of the products. The<br />
objective here is to ensure that the integrity<br />
of the packaging is maintained<br />
even if the product is stored for long<br />
periods.<br />
Different test methods<br />
The high risk involved with leaks in<br />
pharmaceutical container closure integrity<br />
(CCI) testing has resulted in a<br />
strictly regulated environment. The<br />
FDA (USA) and the EMA (Europe), for<br />
example, are two of the key authorities.<br />
These bodies have published directives<br />
that stipulate reliable, physical<br />
measurements to ensure proper<br />
CCI. In practice, however, these directives<br />
are rather broad and give<br />
no concrete recommendations. Often,<br />
the official regulations fail to give<br />
detailed instructions on how the CCI<br />
tests should be carried out.<br />
USP was introduced in<br />
order to provide more clarity in this<br />
respect. This directive concentrates<br />
on sterile and critical pharmaceutical<br />
products and therefore does not<br />
attempt to describe all possible test<br />
methods. It does, however, provide a<br />
good overview and basic guidelines<br />
for the evaluation of various different<br />
methods.<br />
The test methods are divided into<br />
so-called probabilistic and deterministic<br />
test methods, whereby the latter<br />
are generally recommended. By<br />
way of example, we take a closer<br />
look, here, at the blue dye test as a<br />
proba bilistic method, and the three<br />
va cuum test methods as deterministic<br />
test methods.<br />
a) Probabilistic test methods<br />
A probabilistic leak testing procedure<br />
is based on a series of sequential<br />
and/or simultaneous events, each<br />
of which is associated with uncertainties.<br />
These methods are therefore inherently<br />
stochastic, since the results<br />
are randomly affected by probability<br />
distributions. To compensate for<br />
this uncertainty as much as possible,<br />
larger random sample sizes and strict<br />
monitoring of the test conditions are<br />
necessary.<br />
The blue dye test is a probabilistic<br />
test method. This test involves<br />
submerging the test packaging into<br />
a methylene blue solution. The dye<br />
bath is placed in a temporary vacuum<br />
chamber, from which some of<br />
the air is evacuated in the first stage<br />
of the test. After a predefined evacuation<br />
time, the chamber is returned<br />
to atmospheric pressure, or is pressurized.<br />
Finally, after a defined resting<br />
period, the packaging is taken<br />
out of the bath and then cleaned and<br />
visu ally inspected to see whether or<br />
not the blue liquid has penetrated<br />
the packaging.<br />
b) Deterministic test methods<br />
In contrast to probabilistic test<br />
methods, deterministic test methods<br />
are based on phenomena that follow<br />
a predictable chain of events. This is<br />
because the leaks are measured via a<br />

Vacuum technology<br />
Vacuum-based leak testing methods<br />
physical or chemical end point, which<br />
can be easily checked and monitored.<br />
In the vacuum test methods, for example,<br />
the gas flow through an open<br />
leakage channel is measured as a<br />
specific differential pressure is applied,<br />
and the results are then evaluated.<br />
Below, three of the deterministic vacuum<br />
test methods are described in<br />
more detail:<br />
Mass extraction technology<br />
With mass extraction technology, the<br />
packaging specimen is placed in a volume-optimized<br />
vacuum chamber. A<br />
mass extraction sensor, which measures<br />
the gas flow, is installed between<br />
the vacuum reservoir of the test device<br />
and the vacuum chamber (see<br />
Figure 3).<br />
pressure of < 1•10 -02 mbar. In the sensor,<br />
a plasma is ignited with the gas<br />
that escapes through defects in the<br />
specimen, and the gas-specific light<br />
emission is intercepted by an optical<br />
spectrometer. Information about the<br />
integrity of the packaging is then provided<br />
based on the intensity of the<br />
light emission. This test method is selective<br />
for different gases and does<br />
not necessarily require the use of a<br />
volume-optimized chamber, which<br />
means that several test specimens<br />
can be tested simultaneously.<br />
that the test packaging must have<br />
previously been filled with helium.<br />
The helium-filled test specimens are<br />
placed in a vacuum chamber, as with<br />
the other methods. The escaping gas<br />
is ionized in the detector by a heating<br />
filament, and is deflected by the magnetic<br />
field along different curves depending<br />
on the mass.<br />
The incoming ion current is processed<br />
by the electronics in the device<br />
and displayed as a leakage rate<br />
signal. The helium selectivity ensures<br />
high sensitivity.<br />
Fig. 4: Illustration showing the operating principle of O.E.S.<br />
Fig. 3: Operating principle of mass extraction<br />
technology<br />
The first step involves evacuating the<br />
entire device and the chamber to a<br />
pressure of around 1 mbar. The differential<br />
pressure between chamber and<br />
the inside of the packaging now allows<br />
gas to escape through any prevailing<br />
leaks and to flow toward the vacuum<br />
reservoir. The sensor installed in<br />
the flow path measures the gas flow<br />
quantitively and provides information<br />
on the integrity of the test specimen.<br />
With mass extraction technology, the<br />
test specimen does not need to contain<br />
a specific type of test gas.<br />
Helium mass spectrometry<br />
The helium leakage test is the most<br />
sensitive of the deterministic test<br />
methods. The sensor used here is a<br />
magnetic sector mass spectrometer,<br />
which is set up selectively for helium<br />
atoms with a mass of 4. This means<br />
Study comparing different defects<br />
In addition to the aforementioned<br />
study by Kirsch, there is a further<br />
study, by Burrel et al, that compares<br />
the sensitivity of the blue dye test<br />
and the microbial ingress method.<br />
Optical emission spectroscopy<br />
No special test gas is required for the<br />
optical emission spectroscopy (O.E.S.)<br />
procedure either. The gas mixture<br />
present in the head room inside the<br />
packaging specimen is used – usually<br />
ambient air or nitrogen. A multigas<br />
sensor is used to detect gases<br />
that escape from a leaking specimen.<br />
This method involves placing the<br />
test specimen into a vacuum chamber<br />
and evacuating the chamber to a<br />

specimens were then brought to atmospheric<br />
pressure and cleaned before<br />
being visually inspected by three<br />
technicians, in order to obtain the<br />
most objective results possible. The<br />
diagrams in Figure 7 and Figure 8<br />
summarize the results of the study.<br />
With a measured detection limit<br />
of 20 µm for the capillaries and 5 µm<br />
for the micro-pipettes, the blue dye<br />
test is found to have the lowest sensitivity.<br />
The most sensitive method,<br />
even with a helium concentration of<br />
just 20 %, was found to be the helium<br />
mass spectrometry method with approximately<br />
4 µm for the capillaries<br />
and 0.1 µm for the micro-pipettes. If<br />
a helium concentration of 100 % is<br />
assumed, then even the 2 µm capillaries<br />
are measurable. Both the O.E.S.<br />
method, with a detection limit of<br />
~ 7 µm for the capillaries and ~ 0.6 µm<br />
for the micro-pipettes, and the mass<br />
extraction method, with 15 µm for the<br />
capillaries and ~ 1-2 µm for the micropipettes,<br />
lie somewhere between the<br />
other two methods. It must be noted,<br />
however, that the O.E.S. method is<br />
quicker and more sensitive for both<br />
types of defect.<br />
Pros and cons of the<br />
different test methods<br />
There are other factors, in addition<br />
to sensitivity, that may be taken into<br />
account when deciding whether to<br />
switch from the blue dye test to a<br />
vacuum-based test method. A few of<br />
these factors are shown in Table 3.<br />
To allow a comparison of the sensitivity<br />
of the three deterministic vacuum<br />
methods with the known studies<br />
and, above all, with the blue dye test,<br />
a comparative study of different defects<br />
was carried out. Here, the defect<br />
types from the Kirsch study as well<br />
as those from the Burrel study were<br />
used. The types of specimen are explained<br />
in Table 2.<br />
The gas composition makes it<br />
possible to use all three deterministic<br />
methods. The vials were filled with the<br />
gas mixture before they were sealed.<br />
The tests were carried out sequentially<br />
and non-destructively with the<br />

The time required for testing depends<br />
on the type of packaging. In practical<br />
applications, significantly shorter test<br />
durations are usually chosen for the<br />
blue dye test, which further reduces<br />
the sensitivity. The test duration for<br />
vacuum-based methods is significantly<br />
shorter, even taking into account<br />
that several specimens can be<br />
tested at once with the blue dye test.<br />
Furthermore, the evaluation time for<br />
the blue dye test is longer.<br />
With regard to the latest directives,<br />
the great advantage of the<br />
vacuum-based test methods is that<br />
all three deterministic test methods<br />
meet the criteria of USP . Both<br />

As shown in the comparative study,<br />
the vacuum-based test methods are<br />
significantly more sensitive than the<br />
blue dye test. This is a plus point,<br />
since the test requirements for primary<br />
packaging of pharmaceutical<br />
products have become increasingly<br />
stringent in recent years. It must<br />
also be noted, here, that the sensitivity<br />
results for the blue dye test were<br />
achieved based on a lengthy test duration<br />
(60 minutes under vacuum and<br />
the mass extraction method and helium<br />
mass spectrometry method<br />
are explicitly listed as deterministic<br />
methods in this directive.<br />
Also, the vacuum-based test<br />
methods are non-destructive, which<br />
44 PROCESS TECHNOLOGY & COMPONENTS <strong>2023</strong>
Vacuum technology<br />
Vacuum-based leak testing methods<br />
means that the specimens can be<br />
used again, e. g. for additional tests<br />
at a later date. Only the helium test is<br />
limited insofar as it can only be used<br />
for open packaging or packaging that<br />
has already been filled with helium.<br />
Although helium is the most sensitive<br />
method, this limitation means that it<br />
is not usually possible to use the test<br />
during production. Also, setting up<br />
a system for helium testing is more<br />
challenging compared to the other<br />
methods, since helium as a test gas is<br />
not easy to handle.<br />
Only the O.E.S. and mass extraction<br />
methods can be expediently<br />
automated in order to increase<br />
the throughput of tested packaging<br />
units during production. With these<br />
methods, throughput can be increased<br />
relatively easily and cost-effectively<br />
by introducing automated<br />
loading and unloading, for example.<br />
The O.E.S. method can also be used<br />
to test several vials in one chamber,<br />
which can significantly increase the<br />
throughput at little extra cost.<br />
The use of vacuum-based test<br />
methods is subject to the additional<br />
basic restriction that the primary<br />
packaging must be able to withstand<br />
a differential pressure of approximately<br />
1 bar. This can be mitigated<br />
by using volume-optimized vacuum<br />
chambers that have been prepared<br />
for special use, but the method is still<br />
limited, to non-porous primary packaging/packaging<br />
types in general.<br />
Summary<br />
The steadily increasing demands<br />
placed on the integrity of packaging<br />
for pharmaceutical products are<br />
leading to a shift toward different CCI<br />
leak testing methods. Directives such<br />
as USP promote a move away<br />
from probabilistic test methods such<br />
as the blue dye test, which has been<br />
well established for decades, and toward<br />
deterministic test methods,<br />
which also include the vacuum-based<br />
test methods (helium mass spectrometry,<br />
optical emission spectroscopy,<br />
and mass extraction).<br />
The comparative study shows<br />
that a significantly lower detection<br />
limit can be achieved with vacuumbased<br />
test methods than with the<br />
conventional blue dye test. The first<br />
step for users to take when switching<br />
to one of the deterministic test<br />
methods is to carry out a series of<br />
tests to determine the detection limit<br />
currently achieved with their blue dye<br />
test. Users should also be clear about<br />
the critical detection limit that needs<br />
to be achieved in regular testing, for<br />
example during production. This may<br />
already narrow down the range of<br />
possible new test methods.<br />
The area of application must also<br />
be determined. Helium mass spectrometry,<br />
for example, is the most<br />
sensitive test method, but the difficulties<br />
of handling helium make it more<br />
suitable for use in R&D, or in the development<br />
and validation of packaging.<br />
Where in-process testing during<br />
production is required, the blue dye<br />
test can best be replaced by the O.E.S.<br />
or mass extraction test method.<br />

Reduction of production downtime<br />
7 ways to reduce production downtime<br />
Production downtime is one of the<br />
biggest risks in the manufacturing<br />
industry. From equipment failures<br />
to shortages of raw materials, any<br />
production downtime can result in<br />
major losses in revenue and market<br />
share.<br />
There are two types of downtime:<br />
planned and unplanned.<br />
Planned downtime is a scheduled<br />
shutdown of manufacturing equipment<br />
or processes to perform maintenance,<br />
inspections, repairs, upgrades<br />
or manufacturing setups. It is<br />
essential to plan downtime for maintenance<br />
to keep the equipment in<br />
its optimum condition and to avoid<br />
unplanned downtime. Although<br />
planned downtime interrupts the<br />
manufacturing process, you are still<br />
in control of productivity processes.<br />
Thus, preventing production downtime<br />
is key to ensuring productivity.<br />
Follow our seven tips to reduce<br />
machine downtime in your production<br />
line.<br />
1. Develop a system for quickly<br />
identifying and resolving production<br />
issues<br />
The system should gather and analyze<br />
data that gives insight into the<br />
equipment’s total maintenance requirements.<br />
Interpretation of the<br />
data can help your teams resolve<br />
production issues by carrying out<br />
preventive maintenance. The implementation<br />
of such a system allows<br />
factories cut down on time lost due to<br />
production issues and prevent costly<br />
unplanned downtime by alerting employees<br />
of possible upcoming equipment<br />
failures.<br />
2. Use predictive analytics to<br />
identify potential problems before<br />
they occur<br />
Predictive analytics detect patterns<br />
in real-time machine data that could<br />
lead to the onset of a problem. Data<br />
analytics can inform you weeks in<br />
advance about which parts of a machine<br />
are likely to fail. This allows you<br />
to plan your maintenance schedules<br />
and order spare parts in advance,<br />
effectively reducing downtime and<br />
lessening the likelihood of issues reoccurring.<br />
3. Implement a preventive maintenance<br />
program<br />
Preventive maintenance programs are<br />
one of the most effective ways to minimize<br />
unplanned machine downtime.<br />
You can routinely collect valuable<br />
information about your equipment for<br />
Unplanned downtime occurs when<br />
there is an unexpected shutdown or<br />
failure of the manufacturing equipment<br />
or process. It causes foodstuffs<br />
to spoil if they are not packaged, as<br />
well as expensive delays in production<br />
and delivery schedules. Additionally,<br />
when operations are unstable, it<br />
is more difficult to adhere to environmental<br />
regulations and comply with<br />
sustainability measures. This could<br />
result in an increase of environmental<br />
incidents.<br />
a systematic maintenance approach.<br />
With the right targeted maintenance,<br />
you can react to predicted equipment<br />
failures or accidents before they occur.<br />
By reducing the possibility of unexpected<br />
downtime, your staff can focus<br />
on more profitable tasks.<br />
4. Create a system for dealing with<br />
glitches and problems as they arise<br />
Having a system that tracks and monitors<br />
glitches as they arise allows you<br />
to identify the root cause of an issue<br />
in your production line. This will en-<br />

downtime in your manufacturing<br />
process. If operators know how to<br />
use equipment correctly, they are<br />
less likely to halt production and can<br />
respond faster in emergency situations.<br />
Proper training also prevents<br />
unplanned downtime caused by human<br />
error and decreases the risk of<br />
workplace accidents.<br />
able you to understand how production<br />
failures occur and how to prevent<br />
them from happening again.<br />
This reduces unplanned machine<br />
downtime while increasing manufacturing<br />
efficiency.<br />
5. Automate as many processes as<br />
possible to reduce human error<br />

production process is stopped. There<br />
How do you calculate production<br />
downtime?<br />
Use the following equation to calculate<br />
production downtime costs:<br />
Downtime % = (amount of downtime/<br />
planned operating time) * 100<br />
What is the average production<br />
downtime?<br />
Manufacturers lose an average of<br />
800 hours per year, or more than 15<br />
hours per week, of production time<br />
due to equipment downtime.<br />
Let's consider a common scenario for<br />
a parmesan cheese factory:<br />
A parmesan cheese block weighs an<br />
average of 42 kg. The estimated price<br />
is 9 Euro per kilo, amounting to one<br />
parmesan block having a total value<br />
of 378 Euro. Three cheese blocks can<br />
be produced per minute, resulting in<br />
68,040 Euro per hour.<br />
If the parmesan factory experienced<br />
15 hours of unplanned downtime<br />

Conveyance made easy<br />
Powerful rotary lobe pumps for demanding environments<br />
The more demanding the liquid, the higher the demands on the technology<br />
of the pump – a principle that also applies to industrial pumps.<br />
This is because in branches of industry such as the oil or chemical sectors,<br />
pumps must be capable of conveying abrasive, aggressive or viscous<br />
media in a reliable and safe manner. To be able to meet these<br />
requirements, robust, powerful, sophisticated and flexible pump technology<br />
is needed. In addition, it is necessary for the pumps to meet<br />
special industry-specific norms and standards in order to be approved<br />
for use in potentially explosive environments.<br />
High efficiency pump series<br />
With its EP and VY series, Vogelsang GmbH & Co. KG offers two pump<br />
series designed for use in demanding industrial environments. Both<br />
pump series feature rotary lobe pumps made of a flow-optimised onepiece<br />
housing. This ensures a particularly high degree of efficiency.<br />
The pumps reliably convey thin-bodied as well as highly viscous, pure<br />
and solids-laden media at temperatures of up to 200 degrees. They<br />
can be flexibly equipped with variable sealing systems and are ATEX<br />
and TA-Luft compliant. This makes them suitable for use in demanding<br />
areas such as the oil and gas sectors or the chemical industry. Thanks<br />
to increased efficiency and new seal versatility, Vogelsang is opening<br />
up new areas of application for its proven pump technology.<br />
EP series: high performance in extreme conditions<br />
The EP series is designed for extreme conditions such as use in explosive<br />
environments. Unique on the market so far: the high-performance<br />
gearbox, which is built into the pumps and allows for a uniform<br />
pressure output of up to 18 bar. Helical gears in the gearbox<br />
ensure smooth performance and reduce noise emissions. In addition,<br />
pulsation-free conveying reduces wear on the adjacent pipeline to a<br />
minimum. The pumps’ performance spectrum ranges from 1 m³/h to<br />
120 m³/h at a pressure of 10 to a maximum of 18 bar. The free ball passage<br />
is 40 mm. The high-pressure performance and temperature limit<br />
of 200 °C along with its seal versatility make the EP series suitable for<br />
application areas in which companies previously used primarily screw,<br />
gear and progressive cavity pumps. These are usually larger and have<br />
difficulty maintaining the conveyance volume when the viscosity of the<br />
medium changes. The new areas of application include the oil and gas<br />
sector, tank farms, the petrochemical industry and the production of<br />
paints and varnishes, paper, glue and sugar.<br />
For greater operational reliability and temperature resistance,<br />
Vogelsang has also equipped the EP series with an AirGap. This air gap<br />
atmospherically separates the gearbox and the pump chamber, ensuring<br />
that in the event of a leak, liquid will drain off to the outside rather<br />
than entering the gearbox. At the same time, the AirGap protects the<br />
gearbox when conveying hot media. If required, integrated sensors in<br />
all chambers provide information about the current operating status.<br />
VY series: the all-rounder with high efficiency<br />
With the VY series, Vogelsang has further developed its VX series,<br />
opening up new fields of application for its proven pump technology.<br />
Thanks to its highly versatile sealing, the VY series is an all-rounder for<br />
demanding applications such as the chemical industry or the paper<br />
and textile sectors. The VY pumps’ performance spectrum ranges from<br />
1 m³/h to 120 m³/h at a maximum pressure of 10 bar. Integrated sensors<br />
provide all important information about the pump’s operating status.<br />
The VY series is also available with axial and radial wear protection<br />
for media with abrasive components.<br />

temperatures and pressures.<br />
Fig.1: The Vogelsang Automatic Supply Unit (ASU) is compact and increases the<br />
service life of a seal by up to 100 percent.<br />
Wide range of seals for even more flexibility<br />
Depending on the industry-specific standards and requirements, a variety<br />
of different sealing systems can be used in the housings of the<br />
new pump series. In addition to the Vogelsang Quality Cartridge, a<br />
completely pre-assembled mechanical seal in a cartridge design, additional<br />
special mechanical seals are available for the EP and VY series.<br />
Vogelsang has developed the double-acting, TA-Luft compliant mechanical<br />
seal CoX-Cartridge together with leading manufacturers. The<br />
company consequently offers the right solution for various fields of<br />
application, such as for use in the oil and gas industry or in the chemical<br />
sectors. If required, the new pump series can also be equipped with<br />
robust mechanical seals according to API 682.<br />

Service-friendly assembly and cleaning<br />
For a high degree of service-friendliness, both pump series feature<br />
a quick connection in addition to a variety of seals. This allows pipelines<br />
to be connected to pumps in a matter of minutes, thus minimising<br />
time, effort and costs for installation and conversion. Maintaining<br />
the pumps is also quick and easy. Via a quick service cover, wear parts<br />
can be replaced quickly without removing the pump from the pipeline.<br />
The design of the new housings, which minimizes dead space, also allows<br />
for easy cleaning.<br />

New framework concept: even easier maintenance and service<br />
To protect the pump casings of the EP series from abrasive or aggressive<br />
media, the interiors can be fitted with radial casing protection<br />
plates. The innovative framework concept makes it possible to loosen<br />
the screw connection from the outside. It is based on an intelligent fastening<br />
system consisting of four modules that are screwed together<br />
from the outside. This way, the radial protection plates are optimally<br />
positioned and can be changed very easily for servicing. For maintenance<br />
or service purposes, the user only has to remove the covers and<br />
take out the modules. This straightforward handling greatly simplifies<br />
access and reduces downtimes during maintenance or servicing, which<br />
also saves time and money.<br />

seal supply systems and can be easily installed even in tight installation<br />
spaces. The patented system is much less expensive than<br />
currently available options while extending the service life of seals by<br />
up to 100 percent. To maintain the barrier pressure, the ASU consists<br />
of a reciprocating piston pump that adds barrier fluid to the seal with<br />
each revolution. This keeps the overpressure at either 2.0 or 4.3 bar.<br />

means: bpsense integrates unregulated pumps into automated processes<br />
and takes companies a big step further in their efforts to meet<br />
Industry 4.0 conditions. The integration of unregulated pumps into the<br />
digital landscape ensures complete transparency of the fluid system.<br />
bpsense – Entry into the digital world of pumps<br />
Digital. Integrated. Simple. This is the short formula for entering<br />
the digital pump world of BRINKMANN PUMPS. Thanks to the intelligent<br />
onboard sensor technology, bpsense enables the continuous<br />
monitoring of unregulated pumps. The simultaneous evaluation of<br />
acceleration, vibration, sound and temperature sensor signals makes<br />
it possible to detect the status of unregulated pumps in real time. Furthermore,<br />
extensive analysis functionality allows plant operators to enhance<br />
the system availability. bpsense is already prepared for wear<br />
detection of centrifugal pumps, which is a feature that is currently developed.<br />
Among the most important benefits of the digital pump monitoring<br />
system is that bpsense significantly helps to increase production<br />
quality through the traceability of production steps and continuous<br />
process monitoring.<br />
bpsense – seamless integration into digital system landscapes<br />
The pump monitor integrates into digital architectures – even as part<br />
of a retrofit of existing pumps. bpsense is IIoT-capable (Industrial Internet<br />
of Things) and enables the monitoring of complex systems by integrating<br />
unregulated pumps. In addition to optimal process monitoring,<br />
bpsense enables the entry into predictive maintenance – one of the<br />
key elements of Industry 4.0. bpsense impresses with good scalability.<br />
It can be used both as a stand-alone solution and in an online network,<br />
for example when combined with Brinkmann Pumps’ bplogic or a comparable<br />
pump controller. An NFC (Near Field Communication) connection<br />
allows the display of basic data such as energy consumption or<br />
operating hours even when the device is removed from the system or<br />
operating in off-grid environments. All you need is a smartphone and<br />
a standard NFC app, meaning, no cables or special tools are required.<br />
bpsense – Monitoring without additional wiring effort<br />
The bpsense pump monitor can be easily integrated into existing system<br />
landscapes. Optionally, the connection can be made via fieldbus<br />
or a data gateway such as bplogic. Two analog inputs on the bpsense<br />
provide all the prerequisites for the integration of additional sensors.<br />
In addition, there is an IEPE input for connecting external vibration sensors<br />
and an analog output for external actuators. bpsense fits into the<br />
terminal box of the pump drive and uses the existing power supply of<br />
the pump system. Additional wiring or batteries are not required to<br />
mount the pump monitoring system.<br />

Vertical inline twin-screw pumps in block design<br />
The universal pump solution<br />
for space problems<br />
In many companies, lack of space is a major problem. However, relocating<br />
production to another location is usually not an alternative.<br />
So, another solution must be found. It is often difficult do replace a<br />
positive displacement pump in a narrow room or to integrate it into<br />
a new plant if the available installation space is limited. While some<br />
models can be arranged vertically, this usually requires a near wall<br />
or side support frame for vertical mounting. The versatile HYGHSPIN<br />
and CHEMSPIN inline twin-screw pumps offer new approaches that effectively<br />
solve these problems. Thanks to special block design, these<br />
pumps allow free vertical installation in space without lateral structures<br />
for horizontally running pipelines.<br />
Fig. 2: The models of the CHEMSPIN and HYGHSPIN series are also available in<br />
vertical version<br />
The HYGHSPIN and CHEMSPIN pumps have a wide speed range. The<br />
pumping is almost pulsation-free. The low mass inertia of the rotors and<br />
an imbalance-free design also contribute to the smooth running.<br />
Not only for space reasons, but also because of the high viscosity<br />
and volume flow ranges, these twin-screw pumps can effectively replace<br />
other pump types. Thus, HYGHSPIN and CHEMSPIN pumps can also be<br />
used for CIP and SIP processes without an additional bypass. Furthermore,<br />
the pumps are characterized by a low risk of cavitation even when<br />
pumping viscous media. The pumps are available in five sizes each.<br />
Hygienic HYGHSPIN twin-screw pumps are used in the beverage and<br />
food industry, for cosmetics and pharmaceutical products, and animal<br />
feed. Examples of applications for CHEMSPIN pumps are adhesives, underbody<br />
protection, paints, lacquers, cleaning agents as well as tank<br />
farms. Manufacturing is carried out exclusively in Germany.<br />
Fig. 1: Vertical inline twin-screw pumps in block design<br />
The block design is a construction characteristic of the north German<br />
pump manufacturer Jung <strong>Process</strong> Systems, which has been building<br />
hygienic stainless steel pumps according to this principle since 2009.<br />
The pump and the motor shaft are positioned by geometry therefore<br />
cannot shift. Problems caused by unaligned or strained couplings are<br />
avoided. The twin-screw pumps in block design can thus be mounted<br />
vertically on the front cover free-standing like multi-stage centrifugal<br />
pumps.<br />
The modules are very compact and can be easily integrated into<br />
existing plants. When installed vertically, the footprint of a HYGHSPIN<br />
or CHEMSPIN twin-screw pump is reduced up to 70% compared to<br />
other pumps types. The pumps are self-emptying via the lower connection<br />
on the front cover. The main difference to the well-known horizontal<br />
pumps is the front cover especially designed for vertical installation.<br />
This makes it possible to retrofit existing pumps if changes in the<br />
plant require this.<br />

Polymers are used mostly in coagulation and dewatering applications<br />
in the sludge treatment process. Dewatering sludge minimises sludge<br />
bulk, which can reduce the cost associated with storage and disposal<br />
by up to 75 per cent.<br />
There are strong regulatory drivers globally for efficient sludge<br />
dewatering. In <strong>2023</strong>, sludge treatment will be included under the UK<br />
Government's environmental permitting system to encourage use of<br />
sludge as a beneficial resource.<br />
Accurate and reliable metering of polymers in the sludge dewatering<br />
process is essential to ensure it is managed properly.<br />
The Qdos 60 PU offers precise and repeatable flows for many hard<br />
to handle fluids, including viscous flows and aliphatic hydrocarbons, at<br />
linear flow rates of up to 60 l/h and pressures of up to 5 bar. The pump<br />
provides excellent compatibility for complex polymers such as polyacrylamide<br />
(PAM) and other flocculants and coagulants used in wastewater<br />
treatment.<br />
Peristaltic pumps have notable advantages over diaphragm pumps in<br />
PAM metering applications, including enhanced accuracy and reliability.<br />
There is no need for diaphragms, valves, or seals that risk clogging.<br />
The highly innovative design of Qdos pumps means the only part<br />
of the pump that ever requires replacing is the patented ReNu pumphead.<br />
The ReNu pumphead offers repeatable, accurate flow rates,<br />
and lasts longer for tough applications in the field. It takes less than<br />
a minute to replace the ReNu pumphead - a new pumphead is a new<br />
peristaltic pump, ready to serve again.<br />
Adeel Hassan, product manager at WMFTS said, “The new Qdos<br />
ReNu PU pumphead has extended the range of applications of our<br />
Qdos series. These versatile pumps can be used for accurate and safe<br />
dosing of liquids up to 120l/h and 7 bar pressure in various applications<br />
across a range of sectors. They are available in different sizes and<br />
control options depending on requirements.”<br />
WMFTS expects market scope to grow significantly, particularly<br />
with the pump’s integral leak detection and chemical containment<br />
capability, which reduces operators' exposure to chemicals during<br />
maintenance.<br />
Customers in the food and beverage industry can also benefit from<br />
the Qdos 60 PU pump as it is also compatible with fats, oils, and grease,<br />
and is Food and Drug Administration (FDA) and European Commission<br />
(EC) 1935/2004 certified.<br />

The JP-810 is self-priming and, with the selection of suitable conductive<br />
materials and the pneumatic drive, can be used in explosion-prone<br />
areas. It is suitable for ATEX zone 2 or 1 depending on the chosen materials.<br />
Particles or pieces of fruit can also be conveyed thanks to gentle<br />
pumping, depending on the pump size. A major advantage of this<br />
pump is that it can also run dry in addition to being self-priming.<br />
The robust and handy double diaphragm pump is designed<br />
specifi cally for the customer’s medium. All components with media<br />
contact can be carried out in various materials. Aside from the food<br />
industry, these pumps have therefore been established in the chemicals<br />
sector for many years as well. The JP-810 pumps have a pump capacity<br />
of 8 –1050 l/min.<br />
the operating panel after each stroke. The pump stops automatically<br />
after a configured number of strokes or just counts the strokes (no action),<br />
depending on the configuration.<br />
A hose reel is mounted on the carriage so the customer does not<br />
have to search for the compressed air hose. This application is possible<br />
with smaller or larger pumps as well. The smallest volume is 18 ml, the<br />
largest is 9750 ml per stroke.<br />
Sample application 2<br />
Customers have a choice of various connections (flanged, NPT thread,<br />
BSP or Triclamp). A CIP-compatible pump for food applications can<br />
be realised as well. To prevent the (sometimes) unwanted vibration<br />
in the line, a damper can be installed as a sensible accessory in the<br />
pressure line or screwed directly onto the pump. Precise operation<br />
of these pumps can be guaranteed with optional stroke counters.<br />
The pumps are suitable for viscosities up to 55,000 mPas. JP-810 diaphragm<br />
pumps are easy to disassemble and just about all parts can be<br />
replaced quickly.<br />
A customer has an aggressive liquid medium with smaller particles.<br />
However, a suction pipe similar to the Jessberger drum pumps is<br />
needed, rather than a suction hose.<br />
Sample application 1<br />
A customer wants a portable pump for the flexible conveying of chemicals.<br />
The pump needs to be air operated, with an adjustable volume.<br />
The solution<br />
Jessberger configures a JP-810 double diaphragm pump for the customer.<br />
All materials are tailored to the chemicals in question. A damper<br />
is permanently mounted on the pump to prevent pulsation of the<br />
medium. Installed on a carriage, it can now be moved from site to site.<br />
The volume is precisely adjustable per stroke using a handheld<br />
panel. The pump used in this application conveys 700 ml per stroke. To<br />
count the strokes, a pneumatic signal is transmitted from the pump to<br />

The solution<br />
A JP-810 with a threaded bottom suction opening is provided for the<br />
customer. This permits the installation of a fixed suction pipe that is<br />
screwed to the pump, which then sits on the tap hole. The pump can<br />
convey small particles of 2–12 mm, depending on the pump size.<br />
Leakage detection is implemented here so the customer knows<br />
immediately if a diaphragm breaks, even before medium leaks out<br />
of the pump.<br />
This leakage detection is optional and screwed directly into the<br />
pump’s air-side pressure section. It monitors the pressure chamber on<br />
the air side and emits a signal when moisture enters.<br />
The drum pump<br />
The drum pump is one of Jessberger’s best-known products. It always<br />
comprises two components, a motor and a pump unit. The pump unit<br />
consists of a pipe with a rotor or impeller, which pushes the medium<br />
up towards the discharge. Pump units are configured according to the<br />
conveying medium. The pump units can be made of PP, PVDF, stainless<br />
steel or aluminium. A suitable motor (electric or pneumatic) is manually<br />
screwed onto the pump according to the required delivery volume.<br />
No tools are needed. Motors are available up to IP classification 55<br />
and for ATEX applications. Typical fields of application include emptying<br />
IBCs or drums in the chemicals industry and food sector.<br />
Aside from ease of operation, an advantage of the drum pump is that<br />
it can be combined with a nozzle and, depending on the medium, also<br />
with a meter or even volume pre-selection.<br />
Jessberger employees are happy to help you in case of questions<br />
and to support your projects. Many pumps in different versions are<br />
available directly from stock or at short notice. Please visit our website<br />

THINK BIG – Exhaust gas cleaning<br />
for large engines<br />
Users of diesel vehicles are familiar with “AdBlue”. The pollutants produced<br />
during combustion are usually effectively removed directly in<br />
the engine, the exhaust gas drives the turbocharger and then passes<br />
through the oxidation catalytic converter. Now AdBlue - a mixture of<br />
synthetic urea and water - is added. Through a chemical reaction, the<br />
SCR catalytic converter then converts the nitrogen oxides into water<br />
and nitrogen. With the introduction of the EURO 6 emissions standard<br />
in 2015, the use of AdBlue in new cars has become mandatory -<br />
commercial vehicle owners and drivers have been obliged to do so for<br />
much longer.<br />
Jessberger supplies a comprehensive range of accessories for its products.<br />
Hoses and nozzles are offered to customers as a rule in addition<br />
to the pump units and motors. Please note that the pump units always<br />
have to be positioned vertically in the drum or tank. Suitable adapters<br />
are offered. Liquids up to 1000 mPas can be conveyed with this solution.<br />
Jessberger also offers a version of this pump that allows the drum<br />
to be completely emptied.<br />
Industrial and large engines, such as those on ships, are now also subject<br />
to increasingly stringent emission guidelines. Engine manufacturers<br />
are therefore forced to significantly reduce emissions of both soot<br />
particles and nitrogen oxides.<br />
The reduction of nitrogen oxide emissions can be achieved on the<br />
one hand through lower-pollution combustion, i. e. an internal engine<br />
solution, and on the other hand through exhaust gas post-treatment<br />
with an SCR catalytic converter (SCR: selective catalytic reduction). Often,<br />
a combination is used - first lower-pollution combustion, then SCR.<br />
The chemical reaction at the SCR catalytic converter is selective, i.e.<br />
the nitrogen oxides (NO, NO 2<br />
) are reduced preferentially, while undesirable<br />
side reactions such as the oxidation of sulphur dioxide to sulphur<br />
trioxide are largely suppressed.<br />
The reaction requires ammonia (NH 3<br />
), which is mixed into the exhaust<br />
gas. When urea is used, it must first be decomposed in a thermolysis<br />
and subsequent hydrolysis reaction in order to release the ammonia<br />
necessary for the SCR reaction.<br />
The dimensions of industrial and large engines make the use of<br />
dosing systems possible and necessary. The dosing system from sera<br />
is used in exhaust gas post-treatment. The urea solution is dosed from<br />
a day tank with a sera dosing pump. The urea is finely atomised by<br />
means of a nozzle lance. The urea quantity required for optimum pollutant<br />
reduction is specified via a control system by means of a control<br />
signal of the iSTEP series metering pump.<br />

In depth filtration, diatomaceous earth, due to its fine structure, is<br />
washed up with water on cellulose cloths, thus forming a filter cake<br />
that holds back the yeast particles. To prevent this layer from sticking<br />
together, diatomaceous earth continues to be dosed in during filtration,<br />
thus building up new filter layers. Accurate dosing under increasing<br />
counterpressure is therefore crucial to ensure that the beer does<br />
not undergo any negative changes in taste.<br />
A large German private brewery has therefore switched to hose<br />
pumps with the support of AxFlow. A peristaltic metering pump of the<br />
brand realAx is now used for the addition of diatomaceous earth. In<br />
this application, the hose pump delivers at a rate of 125 l/h and a pressure<br />
of 2.5 bar. The realAx ISI 22 model in use operates with roller compression.<br />
In this process, the hose is compressed by the movement of<br />
the rollers and the filter medium in the hose is gently conveyed. Rollers<br />
generate significantly less friction on the hose than shoes. As a result,<br />
the hose wears slower and needs to be replaced less frequently. In<br />
addition, a drive with lower power consumption is sufficient, so that<br />
energy costs are saved during operation.<br />
The dosing of the urea is monitored with pressure and volume flow<br />
sensors. Since optimal atomisation and evaporation of the aqueous<br />
urea solution is crucial for the process, the nozzle lance is also supplied<br />
with compressed air. The compressed air cools the nozzle lance. Furthermore,<br />
the compressed air is used to flush the urea line via a bypass<br />
function between the compressed air and the urea line, so that blockages<br />
caused by crystallising urea are avoided.<br />
In this way, sera products ensure clean air by post-treatment of exhaust<br />
gases from industrial and large engines.<br />

Beer filtration with improved results<br />
thanks to the right pump technology<br />
In breweries, diatomaceous earth is often used to filter the beer. Its<br />
fine-pored structure absorbs the suspended particles from the beer,<br />
resulting in a clear product. In diatomaceous earth filtration, it is therefore<br />
essential that the particles are pumped gently and that the porous<br />
surface of the diatomaceous earth is preserved. AxFlow has used hose<br />
pumps in many breweries here, most recently in a large German private<br />
brewery.<br />
After the new beer has been given its taste 'finishing touches' in the<br />
maturation cellar, the turbid matter must be filtered off in the case of<br />
clear beer varieties. This filtration removes residual yeast cells and other<br />
turbidity from the beer. Depth filtration and screen or surface filtration<br />
are common processes in this case, using both feed and discharge<br />
pumps for diatomaceous earth.<br />
Composed mainly of the constituents of fossil algae, diatomaceous<br />
earth is an excellent filter medium. Optimized filtration improves the<br />
appearance, shelf life and saleability of the beer.<br />
realAx ISI 22 roller hose pump in a large German private brewery<br />
As part of the installation, AxFlow service engineers assisted with the<br />
initial cleaning of the hose pump and system. In a first step, the pump<br />
was cleaned with diluted caustic solution in a second step with an acid<br />
mixture and then rinsed.<br />
As a valveless technology, hose pumps stand out for their troublefree<br />
operation. Despite the highly abrasive properties of diatomaceous<br />
earth, hose pumps operate reliably and require less maintenance than<br />
comparable pump technologies. At the same time, realAx brand hose<br />

pumps with high-strength hoses have strong resetting forces and thus<br />
excellent suction performance. The food-grade hoses, made of natural<br />
rubber, are reinforced with multiple layers of nylon fabric. They are<br />
manufactured with precision surfaces so that there is even less friction,<br />
resulting in a high efficiency and long durability.<br />
The brewmaster is very satisfied with the filtration result. Gentle<br />
conveying with roller hose pumps preserves the surface structure of<br />
the diatomaceous earth and results in a safe product that is attractive<br />
to the end customer.<br />

Wide-range Speed Control for Diaphragm Metering Pumps<br />
Energy efficient in accordance with<br />
class IE5+: Compact permanent magnet<br />
synchronous motor extends control<br />
range and reduces total cost of<br />
ownership<br />
In many applications, metering ingredients in the pharmaceutical or<br />
food industry for example, pumps are required that not only can be<br />
precisely controlled in terms of flow rate and dosing time, but also<br />
convey the ingredients particularly gently. To enable the proven pump<br />
units of the ecodos series from LEWA GmbH to fulfill this demanding<br />
task with even more flexibility and energy efficiency in the future, the<br />
manufacturer is expanding the portfolio to include a new form of widerange<br />
speed control. Alongside asynchronous motors and servomotors,<br />
permanent magnet synchronous motors, or PMSMs for short, are<br />
also used now. They are characterized by high energy efficiency and a<br />
control range greater than 1:200. This significantly expands the range<br />
of applications.<br />

be dispensed with and the required flow rate can be realized by speed<br />
control only. The PMSM also has a constant torque, from engine<br />
speed 0 rpm (standstill) up to the rated speed of the motor. This ensures<br />
particularly smooth and gentle system start-up, since each process<br />
can be started with a pump capacity of 1 percent instead of the<br />
usual 10 percent.<br />
The diaphragm metering pumps in the LEWA ecodos series are particularly<br />
well suited for applications in the food or pharmaceutical industries.<br />
All materials in contact with the fluids used in the pump units<br />
meet the FDA and USP Class VI requirements, and the EU directives for<br />
the food industry. In the hygienic version, for example, the pump head<br />
is made of PP or electropolished stainless steel with a surface roughness<br />
< 0.5 µm. This facilitates cleaning of the surfaces in contact with<br />
the product.<br />
Wide-range speed control with permanent magnet synchronous<br />
motor extends the range of applications<br />
Unlike the asynchronous motor, the rotor of this drive consists of<br />
permanent magnets and rotates synchronously, i.e. without loaddependent<br />
slip. Among other things, it features an extreme control<br />
range, which often makes the use of multiple pumps for different flow<br />
rates unnecessary. Particularly in the case of multiple pumps, an additional<br />
manual stroke adjustment or electric stroke adjustment can<br />
Fig. 2: In contrast to the ASMs shown, the constant torque of the PMSM enables<br />
continuous operation at low speeds. Oversizing for the required pump starting<br />
torque has become unnecessary due to the high overload capability of the PMSM.<br />
(Source: LEWA GmbH)<br />
It also features a high short-term overload capacity, which enables<br />
a drive design without oversizing for the starting torque. As a result,<br />
smaller, more cost-efficient sizes can be realized than with classic<br />
drives. Like the asynchronous motor, the PMSM can be controlled via<br />
a standard frequency converter, so users can rely on common parts.<br />
The compact drive can be easily cleaned due to its fanless design and<br />
offers high IP protection. If required an additional conversion process<br />

From the outside the KAMAT unit looks like an ordinary 20-foot-long<br />
container with soundproofing on the inside but it is filled with hightech.<br />
The compact format allows it to be transported and operated<br />

industrial engine with eight cylinders arranged in a V-shape, an automated<br />
ZF Traxon transmission and a high-performance pump work in<br />
a perfect triad here.<br />
New pump concept at KAMAT:<br />
Perfect triad of industrial engine,<br />
automated transmission and KAMAT<br />
high-performance pump<br />
In cooperation with Scania from Sweden KAMAT has developed a technically<br />
complete new mobile high-pressure pump unit. The made in<br />
Witten container unit represents a never seen unity of a Scania industrial<br />
V8 diesel engine, the automated Traxon-gearbox by ZF and our<br />
tried and true high-pressure plunger pumps. The innovation of the<br />
high-pressure pump unit lies in the interaction and communication of<br />
all of these three outstanding components.<br />
A central control unit steers all three components instead of the usual<br />
three separate controls. The control with three separate controls usually<br />
led to an inefficient operation at non optimal rpm. This led to a reduction<br />
in longevity of all parts of the high-pressure pump unit while<br />
also reducing the energy efficiency of the entire application.<br />
The well tested and intelligent V8 Scania with its 450 kW of KAMAT’s<br />
supplier ScanDiesel, the ZF gearbox as well as the KAMAT pumps are<br />
now controlled by a singular fully automated control unit. All the user<br />
has to do is to enter the wanted working pressure into the main control<br />
panel. After that, the fully automated control unit recognizes which<br />
water tools are being used and adjusts all three components to work at<br />
optimal efficiency for the pressure and flow rate needed. This doesn’t<br />
just increase the longevity of any component but also reduces fuel consumption<br />
and therefore costs of running drastically.<br />
Fig. 2: The turnkey unit viewed from the outside: A normal 20-foot container but<br />
with a perfect interior.<br />
The mission of this unique development is to change the way mobile<br />
units are operated. It is delivered key-ready and can be operated with<br />
very little knowledge needed. It reduces the chances of operator error<br />
induces inefficiencies to minimum and therefore achieves to date unseen<br />
efficiencies. “With our new system, we replicate what only experienced<br />
operators have been able to do so far, for everyone” explains<br />
KAMAT general manager Dipl. Ing. Jan Sprakel, who came up with the<br />
idea for the development, always striving for improvement.<br />
The unit is now set up in a way that it recognizes all kind of tools<br />
without any need for manual input. Therefore, long working task with<br />
multiple different tools can be done without the time-consuming<br />
breaks needed for adjustment of the parameters. “From now on, the<br />
user only has to enter the wanted working pressure and from there<br />
on the control unit takes over and adjusts everything as needed.” Jan<br />
Sprakel summarizes the advantages of the new designed high-pressure<br />
pump unit.<br />
The design of the new high-pressure unit is mainly aimed at industrial<br />
service providers. It is not unusual to accumulate above 10 hours<br />
of runtime a day for a unit like this when it comes to industrial cleaning<br />
of tanks for example. In this environment, the sustainability of the<br />
drive plays an important role. Therefore, the new unit can drastically<br />
reduce the running cost and increase the maximum runtime of each<br />
of the components. The fuel efficiency being important in two different<br />
ways, firstly the cost of running and secondary reducing the time it<br />
takes to finish a task. Every litre and minute that a unit safes is money<br />
for the entrepreneur.<br />

receives order for pilot project testing<br />
H 2<br />
-pressure tanks<br />
The year <strong>2023</strong> starts with an unusual and green order at KAMAT which<br />
we received at the end of 2022: Within a project of the federal ministry<br />
for digital affairs and transport, trying to decrease pollution caused by<br />
traffic, KAMAT is delivering two high-pressure pump units to be used in<br />
pressure testing systems for hydraulic pressure tests on H 2<br />
gas tanks.<br />
chokes, sensors and controls) is to precisely hit and control the desired<br />
pressure.<br />
Due to the design of the KAMAT pump, upper pressures of up<br />
to 1350 bar can be achieved in this setup. This raises the question<br />
of how exactly the pumps can be pressure-controlled. A suitable solution<br />
was designed with the engineering department, including the<br />
necessary valve, control and automation technology. All of the parts<br />
needed are designed and manufactured in-house at KAMAT – All<br />
from one provider.<br />
Last year the company Industrieanlagenbetriebsgesellschaft mbH with<br />
headquarters in Ottobrunn (IABG) reached out to us with a contract<br />
within the pilot project commissioned by the ministry for the pressure<br />
testing of hydrogen tanks. The IABG is building a hydraulic testing<br />
unit for hydrogen tanks that are to be used in various vehicles. This<br />
includes the technology for the filling of such tanks. IABG asked us to<br />
check whether KAMAT’s high-pressure units could meet the requirements<br />
needed for the project. Sales director Fabian Hoff didn’t hesitate<br />
for long. He was confident that KAMAT could meet the requirements.<br />
Straightaway he started talks with the head of the project. He requested<br />
more information to create the best possible technical solution for<br />
the application.<br />

specialize in hydrogen tanks, filling of tanks, testing and commercial<br />
vehicles. This consortium is supported by the Ministry of Digital<br />
Affairs and Traffic with 25 million Euro for a period of three years<br />
that started 2020. The consortium’s aim is to provide a market ready<br />
solution for hydrogen driven vehicles, applications and filling technology<br />
by 2025.<br />

The task: Impinging tanks with a minimum volume of 600 l with cyclic<br />
pressure using water as media. According to the IABG, there are only<br />
very limited test options for tanks of this size class, which is why IABG<br />
cannot fall back on existing systems and they therefore weren’t sure<br />
for the feasibility of the project. “The customer, before starting talks<br />
with us, had talked to other companies about possible solutions. But<br />
all of them were limited by volume due to the use of pressure transducers.<br />
The tanks that are to be tested in this project needed a lot<br />
more volume than others were able to work with, that is where we<br />
came in to play with our high-pressure plunger pumps. Because our<br />
high-pressure pumps are basically also suitable for volumes well over<br />
600 l”, says a delighted Fabian Hoff.<br />
At any rate, a key function our units have to fulfil is both to run<br />
1-10 full cycles per minute and to be able to release that pressure after<br />
ramping it up. Accordingly, that means that our pumps have to be<br />
operated in intervals or with swelling loads. Another unique challenge<br />
when strength testing for pump systems (including valves, regulating<br />

By means of the Smart Pump Assistant detailed operational parameters<br />
like temperature and pressures can be visualized. If parameters<br />
are exceeded, the customer receives an alert.<br />
The implementation of the knowledge gained through the ABEL<br />
Smart Pump Assistant results in the customer saving significant quantities<br />
of time, costs and energy in the production process while at the<br />
same time accelerating the productivity throughout the company.<br />
Figure 2 below shows that the ABEL pumps have managed 46 filter<br />
press cycles in 5 production days without any standstill.<br />
On the whole, the company SOLVALOR is very satisfied with the<br />
performance of the ABEL pumps as well as the ABEL services.<br />
The plant<br />
In spring 2021, two ABEL hydraulic diaphragm pumps were put into operation<br />
at the plant of this French customer. These diaphragm pumps<br />
of the type HMD-G-80-1000 are used for filter press feeding at a level<br />
of 80 m³/h and 12 bar.<br />
Fig. 2: “The ABEL pumps have allowed me to increase the productivity dramatically<br />
and to transfer more slurry, because – compared with the prior technology –<br />
I can manage more filtration cycles in the same time. Also, it doesn’t matter any<br />
longer what kind of slurry I transfer – the ABEL pump will get the job done!”, says<br />

The ABEL piston diaphragm pump is an important component in filter<br />
press feeding. Among the advantages of ABEL pumps compared with<br />
other types of pumps are:<br />
– High wear resistance<br />
– Robustness and durability<br />
– Very long service intervals<br />
– Low energy requirements<br />
– Reduction of operating costs<br />
The ABEL piston diaphragm pumps fulfil the requirements of filter<br />
press feeding in various ways.<br />
Equipped with an analogue pressure transducer and a frequency<br />
converter, the initial flow rate, the break-point and the minimum flow<br />
rate can be set easily. It is particularly important that these components<br />
can be varied if required, which is crucial for some applications.<br />
Compared with other feeding pumps, whose feed rate – due to<br />
the design – is dependent on the counterpressure, the flexibility of the<br />
ABEL pumps provides a real added value – particularly so when the<br />
customer needs filtration times to be as short as possible and a high<br />
solids content.<br />
The ABEL hydraulic diaphragm pumps are extremely energy-efficient<br />
and durable and they have a high efficiency rate when used as<br />
filter press feed pumps.<br />
Due to their robust design, the ABEL piston diaphragm pumps are<br />
also employed in other industrial areas throughout the world for the<br />
transport of difficult media. ABEL pumps are used, for example, in<br />
mining for dewatering mines and in the water and sewage industry<br />
as transport pumps. Furthermore, many customers in a wide range of<br />
industrial sectors use the ABEL pumps for spray dryer feed and rotary<br />
kiln charging.<br />

DIAM & DDM<br />
DIAM & DDM <strong>2023</strong> - Double pack<br />
for the 10 th anniversary<br />
A special year is coming for all DIAM<br />
& DDM interested parties. In addition<br />
to the double pack this year,<br />
the trade fair for industrial valves<br />
& sealing technology celebrates its<br />
10 th anniversary. The DIAM & DDM<br />
will kick off the anniversary year on<br />
June 14 th and 15 th <strong>2023</strong> in Leipzig/<br />
Schkeuditz. This is already the third<br />
time that the national meeting takes<br />
place in the Central German Chemistry<br />
Triangle. On the grounds of the<br />
Globana Trade Center, all conditions<br />
for an uncomplicated trade fair presence<br />
are in place. You will find an optimal<br />
connection by the airport and<br />
motorway, the hotel right next to the<br />
exhibition hall as well as a comfortable<br />
parking situation.<br />
The Bochum edition of the DIAM &<br />
DDM will be on agenda in the autumn<br />
of this year, exactly on November<br />
the 8 th and 9 th . Since the beginning<br />
in 2013, it will be held for the 6 th time<br />
in the Jahrhunderthalle Bochum. In<br />
October 2021, the DIAM & DDM returned<br />
to the face-to-face event<br />
during the ongoing pandemic. More<br />
than 1.600 visitors came to Bochum.<br />
The consequence of this consistently<br />
very successful event was a high rebooking<br />
rate of exhibitors. Since the<br />
start of the fair, this was the highest<br />
percentage rebooking rate.<br />
Exactly 10 years ago, the premiere<br />
took place with 90 exhibitors in<br />
the Jahrhunderthalle Bochum. At that<br />
time, the event was still under the<br />
sole DIAM flag and developed steadily<br />
from time to time, before the DDM –<br />
the trade fair for sealing technology<br />
was added for the first time in 2017.<br />
This is how the trade fair for industrial<br />
valves & sealing technology<br />
was created. Since the beginning, the<br />
organiser has been in close cooperation<br />
with its exhibitors. Many exhibitors<br />
use the term “family reunion”.<br />
The initiator of the DIAM & DDM –<br />
Malte Theuerkauf – takes a stand on<br />
this: “It is precisely this term “family<br />
reunion” that makes it all. The entire<br />
team is looking forward to our two<br />
trade fairs in this special year for all<br />
of us. Personally, I am thrilled with<br />
the popularity of the DIAM, which was<br />
launched in 2013. There were more<br />
and more exhibitors, the DDM joined<br />
the DIAM in 2017 and the exhibition<br />
concept has established itself. It fills<br />
me with pride how the DIAM & DDM<br />
has matured into the familiar and national<br />
industry meeting for industrial<br />
valves & sealing technology. For this<br />
I would like to thank all exhibitors,<br />
partners, visitors and employees.<br />
With two of our own events and our<br />
10th anniversary, for which we have<br />
some surprises, there is every reason<br />
to be excited about the DIAM & DDM<br />
anniversary events.<br />

Energetic use of biogas<br />
Farm energy independence –<br />
for a crisis-proof future<br />
Helei Ammura<br />
Natural gas has been in short supply<br />
since the start of Russia’s war against<br />
Ukraine. The energy supply has been<br />
a leading topic in Germany over the<br />
past year. Germany does however<br />
have a very large pool of biomass.<br />
Around 9,600 biogas plants (as of<br />
August 2022) are producing more<br />
than 5,600 megawatts of electricity<br />
in Germany right now. At the latest<br />
since 1 January 2021, the operators of<br />
biogas production plants have been<br />
forced to reconsider their operations.<br />
Funding under the Renewable Energies<br />
Act (EEG) for renewable energy<br />
plants, which have been subsidised<br />
for the last 20 years, has ended. The<br />
good news: Notwithstanding the end<br />
of funding, an economically viable<br />
solution is available to operators by<br />
converting to an intelligent own use<br />
concept. This is particularly beneficial<br />
for operators in the current situation.<br />
Using biogas to produce biomethane<br />
as an energy carrier makes a significant<br />
contribution to sustainable development,<br />
especially in rural areas.<br />
It considerably improves the security<br />
of the energy supply.<br />
Biogas processing is the first step in<br />
using biogas as biomethane. It primarily<br />
involves separating the accompanying<br />
carbon dioxide gas and other<br />
components from the raw biogas<br />
using various technical processes.<br />
The resulting biomethane is chemically<br />
equivalent to natural gas. It can<br />
be fed into the natural gas network<br />
and thus used just like natural gas.<br />
Biomethane made from biogas is a<br />
renewable energy source. It is an important<br />
part of the energy transformation<br />
and can be readily used anywhere<br />
that natural gas is consumed.<br />
Plants that produce biogas and<br />
process this into biomethane have<br />
increasingly established themselves<br />
in recent years. Martin Schulze<br />
therefore implemented the concept<br />
described above in his farming<br />
operation in 2022. BAUER<br />
KOMPRESSOREN supplied the filling<br />
station technology required for<br />
the project. Mr Schulze was willing<br />
to discuss several points and explain<br />
them in more detail from the perspective<br />
of a farming operation:<br />
Mr Schulze, what exactly prompted<br />
you to process biogas produced on<br />
your farm when EEG funding ended?<br />
I believe we need to explore new fuel<br />
supply sources, regardless of compensation<br />
for electricity produced<br />
from biogas under the EEG or in the<br />
market. Using biomethane in agriculture<br />
became possible with the advent<br />
of biomethane-fuelled tractors. A degree<br />
of energy supply independence<br />
also played a role.<br />
To what extent was this compatible<br />
with your farming concept?<br />
Since we have our own biogas plant,<br />
the only questions that remained after<br />
the methane-fuelled tractor from<br />
New Holland became available was<br />
how to produce our own fuel-quality<br />
biogas and get it into the tank. I<br />
studied a do-it-yourself gas purification<br />
solution for a few months because<br />
small processing plants are not<br />
available in the market. Then I was offered<br />
a pilot plant by chance. Now I<br />
have my own biomethane supply on<br />
the farm along with the compressor<br />
system and filling station.<br />
Biomethane fuelling solutions –<br />
economical for the future<br />
As a premium manufacturer and natural<br />
gas compression pioneer with<br />
more than 40 years of global experience,<br />
BAUER KOMPRESSOREN has<br />
the required state-of-the-art technology<br />
in the form of tailor-made,<br />
turnkey fuelling systems from one<br />
source. The sustainability-oriented,<br />
ISO 14001 certified company puts<br />
great emphasis on actively working<br />
towards reaching climate protection<br />
and energy transformation<br />
targets. Thus the company firmly<br />

Compressors and Systems<br />
Energetic use of biogas<br />
supports the continued operation<br />
of existing renewable energy<br />
plants for bio methane production.<br />
Its fuelling systems are<br />
generally designed to be used<br />
with biome thane as well as conventional<br />
natural gas. As a rule,<br />
they consist of a high or medium-pressure<br />
compressor system<br />
that is tailor-made for fuelling, a<br />
gas drying and filtering system,<br />
an appropriate storage solution<br />
and the fuel dispenser. The practical,<br />
modular design of the system<br />
supports fast, straightforward<br />
installation and integration<br />
into existing infrastructures.<br />
System versions with a low,<br />
moderate or high daily output are<br />
available, tailored to the respective<br />
demand. This is illustrated by<br />
the following example of farmer<br />
Martin Schulze’s concept:<br />
Martin Schulze work yard<br />
filling station – a compact,<br />
energy-independent and<br />
highly economical solution<br />
The small, compact module<br />
consists of a compressor with<br />
a flow rate of 11-51 Nm 3 /h or<br />
7.9-36.7 kg/h, an intake pressure<br />
of 0.05-4 bar (gauge) and a discharge<br />
pressure of 250-300 bar.<br />
In continuous operation, the daily<br />
delivery rate of the compressor<br />
unit is 190-880 kg in 24 hours.<br />
The system has integrated filter<br />
and final drying cartridges installed<br />
on the high pressure side.<br />
These clean the compressed gas<br />
and remove residual moisture.<br />
The high-pressure gas reservoir<br />
is comprised of individual<br />
Fig. 2: B3360 storage module<br />
Fig. 3: Fast fill/slow fill post filling station<br />
high-pressure cylinders mounted<br />
on one frame. The standard<br />
capacity is up to 42 high-pressure<br />
storage cylinders, with a filling<br />
volume of 80 litres per storage<br />
module. Capacities of 265 m 3<br />
to 1105 m 3 of geometric gas filling<br />
volume at 300 bar can thus<br />
be realised.<br />
A “fill post” is used as the fuel<br />
dispenser since public fuelling<br />
is not provided. This model was<br />
developed especially for simple,<br />
temperature-compensated and<br />
low-cost fuelling. The fuel dispenser<br />
series is frequently used<br />
for natural gas filling stations in<br />
work yards that are not staffed.<br />
Depending on the filling<br />
capa city, fuel volume and compressor<br />
model, fuelling times of<br />
around 5 minutes are obtained<br />
with the “fast fill post” version<br />
used here. The Munich-based<br />
manufacturer offers the “slow fill<br />
post” version without the integrated<br />
storage module for applications<br />
where the fuelling time is<br />
less important. Here vehicles are<br />
fuelled directly from the compressor.<br />
For technical reasons,<br />
fuelling times vary considerably<br />
in this case. Overnight vehicle<br />
fuelling is an ideal application<br />
scenario.<br />
Using a fuel dispenser is required<br />
by law for the operation<br />
of public filling stations. Fuel<br />
payment at the dispenser, without<br />
staff, can be realised with<br />
a customer activated terminal.<br />
The dispenser can also be realised<br />
with a calibratable flow meter<br />
(display of the delivered fuel<br />
volume in kg or m³) and a display<br />
panel that shows the specific gas<br />
price and the total price in the desired<br />
currency.<br />
Core competence –<br />
economical and comprehensive<br />
project development<br />
First the project engineers select<br />
the best site for the filling station<br />
according to the customer’s<br />
speci fications and in close coordination<br />
with them. Special attention<br />
is paid to exact compliance<br />
with legal regulations. By<br />
mini mising explosion protection<br />
zones and tailoring the size<br />
of the filling station, the Munichbased<br />
supplier is able to find<br />
an optimal installation solution,<br />
even when the available space<br />
presents a challenge. Installation<br />
comprises the complete pipe-<br />
work for the system according to<br />
the applicable directives. This includes<br />
all pressure lines from the<br />
compressor to the reservoir and<br />
from there to the filling station<br />
and dispenser. An inspection by<br />
an approved regulatory authority<br />
such as TÜV follows. The project<br />
team manages and coordinates<br />
the necessary scheduling with<br />
the companies and authorities<br />
that are involved.<br />
Service technicians install the<br />
electrical wiring for the compressor<br />
system and the filling station/<br />
dispenser according to the approved<br />
plans. The operator only<br />
has to provide a high-voltage<br />
connection. After installation, the<br />
compressor system is started up<br />
for the first time and inspected<br />
again in detail.<br />
End-to-end project organisation<br />
is handled by the supplier.<br />
This includes the installation<br />
and putting into operation<br />
of the compressor/storage unit<br />
and fuel dispenser technology<br />

Biomethane supply with BAUER<br />
Aside from filling stations, the compressor<br />
manufacturer from Munich<br />
has developed special compressor<br />
systems for biomethane production<br />
based on its expertise acquired<br />
over many years and successfully established<br />
them in the market. They<br />
are used among other things for<br />
the seasonal compensation of transport<br />
fluctuations and network overloads:<br />
When a low-pressure line is<br />
overloaded, for instance by an increase<br />
in the biomethane supply,<br />
the excess biomethane-natural gas<br />
mixture can be supplied to a highergrade<br />
network. Existing buffer volumes<br />
in high-pressure transmission<br />
networks are more effectively utilised<br />
as a result. Biomethane is supplied<br />
to a natural gas network in various<br />
network types with pressure ratings<br />
from PN10 to a maximum of PN100.<br />
Climate-neutral mobility for the<br />
hydrogen future<br />
Based on its sustainability-oriented<br />
philosophy, the company stands for<br />
climate-friendly mobility concepts<br />
without compromise. The manufacturer<br />
as a technology leader in mechanical<br />
engineering and a member<br />
of Zentrum Wasserstoff.Bayern<br />
(H2.B) therefore consistently supports<br />
the broad establishment of this<br />
future energy carrier with a recently<br />
launched development offensive for<br />
H 2<br />
filling station systems.<br />

system will have a cooling capacity<br />
of 15 kW at about -269°C.<br />
The ions are accelerated with<br />
high electric fields. Magnets are<br />
used to direct and bundle them.<br />
The ions can be accelerated to a<br />
maximum speed of around 90 percent<br />
of the speed of light, i.e. almost<br />
270,000 km/s. Researchers from all<br />
over the world use the accelerated<br />
ions at GSI for experiments in a variety<br />
of research fields, from particle,<br />
nuclear and atomic physics to plasma<br />
physics, materials research, biophysics<br />
and tumor therapy.<br />
Together with its partners such<br />
as Enerproject S.A. and Linde<br />
Kryotechnik AG, both from Switzerland,<br />
the compressor manufacturer’s<br />
team faced major challenges - and<br />
mastered them. To cool the magnets,<br />
it is not possible to use ammonia<br />
or any other refrigerant to<br />
reach the required temperature.<br />
This is only possible with helium, the<br />
“coldest” element on earth. The normal<br />
boiling point of helium is 4.2 K,<br />
which corresponds to about -269 °C.<br />
The entire plant contains 12.5 tons<br />
of helium. The project manager and<br />
key account for gas compressors<br />
(DACH), explains: “Helium is an expensive<br />
and extremely rare chemical<br />
element that cannot be produced artificially.<br />
Therefore, the loss and contamination<br />
of helium must be minimized<br />
in order to reduce costs for<br />
the customer. For this reason, the installation<br />
of a second O-ring seal for<br />
the low-pressure compressors, as<br />
well as a leak test (sniff test) with helium<br />
were necessary.”<br />
For the evaluation phase, the supplier<br />
was able to recruit an expert for<br />
the team: a specialist for screw compressors<br />
and with a cryo technical<br />
background due to his research<br />
time at the Technical University of<br />
Dresden. He provided valuable technical<br />
advice to the various parties<br />
involved in the project phase and is<br />
keen to promote the use of the supplier’s<br />
screw compressors for helium<br />
and hydrogen applications.<br />
Reference for future projects<br />
The FAIR project is an important reference<br />
for the compressor manufacturer<br />
for further future projects<br />
in the application of helium in refrigeration<br />
for such low temperatures<br />
as for the FAIR ring accelerator. Another<br />
challenge was to coordinate<br />
this long-term project in close cooperation<br />
with all parties involved<br />
so that the compressors could be<br />
de livered on time. For example, leak<br />
testing by the ILK Institut für Luftund<br />
Kältetechnik Dresden had to<br />
be organized after completion and<br />
prior to shipment. According to current<br />
planning, the helium compressor<br />
plant is scheduled to be commissioned<br />
in 2024 and the first jet<br />
in 2025.<br />

FAIR mega construction project<br />
The FAIR particle accelerator facility in Darmstadt is one of the world's largest construction projects for cutting-edge<br />
international research. Among other things, an underground accelerator ring tunnel 1,100 meters long, laboratories<br />
and other operational and utility buildings are being built on an area of around 150,000 square meters. The transfer<br />
building is the most complex building in the facility. It is the central hub of the facility beamline. The 1,100-meter tunnel<br />
for the SIS100 particle accelerator will also be up to 17 meters underground. Adjacent to the accelerator tunnel itself<br />
will be a supply tunnel that will house, among other things, lines for electricity and liquid helium, space for power<br />
supply equipment and facilities for controlling ion beam quality.<br />
An integrated construction schedule was developed for the multinational, highly complex mega-construction project,<br />

GER4TECH relies on BOGE<br />
Uninterrupted compressed air supply<br />
with added efficiency<br />
From simple sheet metal parts to<br />
complex assemblies and entire<br />
machine parts, GER4TECH GmbH<br />
in Redlham (Austria) offers a<br />
broad wide range of metalworking<br />
services. The company also has substantial<br />
expertise in developing customer-driven<br />
solutions for automated<br />
manufacturing processes.<br />
It depends on compressed air<br />
in almost all of its production<br />
areas, which is where compressed<br />
air expert BOGE comes in – ensuring<br />
an efficient and reliable supply to<br />
the company thanks to three of its<br />
screw compressors. But that’s not<br />
all – the supplier has also helped the<br />
company achieve excellent system<br />
availability levels of over 95 per cent<br />
and a significant increase in efficiency<br />
thanks to consistent recirculation<br />
of waste heat.<br />
a broad range of services in the laser<br />
cutting and bending to machining<br />
(turning, milling) and welding sectors.<br />
In addition to metalworking with the<br />
latest technology, it also provides<br />
customised automation projects and<br />
currently employs 75 members of<br />
staff in its metal and mechatronics<br />
departments. The family-owned company<br />
requires compressed air for<br />
numerous metalwork processes: as<br />
pneumatic actuator for the laser cutting<br />
machines, for the break forming<br />

All the compressors are frequencycontrolled<br />
and guarantee a constant<br />
compressed air supply throughout<br />
all three shifts every day. An oil-water<br />
separator purifies the condensate<br />
and reduces the residual oil content<br />
to under 10 ppm.<br />
Flexibility and efficiency<br />
The compressors from the Bielefeld<br />
supplier with tried and tested airends<br />
and high-quality components ensure<br />
maximum efficiency, with SLF<br />
devices offering the highest standards.<br />
On one hand, the fully designed<br />
in-house airend permits high free air<br />
delivery combined with a low power<br />
demand and the highly developed<br />
oil separation system with horizontal<br />
receiver results in optimum efficiency<br />
yield. The direct drive and frequency<br />
control complete the highly<br />
flexible system that can adapt to the<br />
actual demand. The clear layout of<br />
the functional areas ensures fast and<br />
simple maintenance. The ingenious<br />
construction concept, high-grade<br />
components and flexible fields of application<br />
make the screw compressors<br />
particularly reliable and longlasting.<br />
As a belt-driven compressor<br />
with integrated frequency regulation,<br />
the C 25 F screw compressor also<br />
adapts the volumetric flow rate to the<br />
actual demand, meaning the energy<br />
consumption falls as the compressed<br />
air demand drops. Idling is also minimised<br />
which, especially in the metalworking<br />
sector with its wildly fluctuating<br />
compressed air demand, is a<br />
huge advantage. Soft starts and stops<br />
conserve the material and prolong<br />
the service life of the device. And, in<br />
addition, thanks to its compact, integrated<br />
construction, pressure losses<br />
are kept to a minimum.<br />
“We really value maximum reliability<br />
and high system availability,<br />
which for compressors from the supplier<br />
reaches an impressive 95 per<br />
cent,” tells the Managing Director.<br />
“If we should ever need any repairs,<br />
we know we can count on 24/7 support,<br />
too”. Certified technicians are<br />
available around the clock for any<br />
questions and technical assistance.<br />
On top of that, the Austrian company<br />
also benefits from high spare part<br />
availability from the compressed air<br />
specialist. Regular maintenance using<br />
original spare parts guarantee continued<br />
high system efficiency and a<br />
five-year warranty on all replacement<br />
parts round off the service package.<br />
“We’re extremely happy with the<br />
quality of the compressed air and the<br />
reliable operation of the systems”,<br />
concludes the Managing Director. “In<br />
addition to the technology itself, we<br />
appreciate the extremely extensive<br />
customer-focused service. We feel<br />
very well supported and prepared for<br />
whatever the future might hold”.<br />

Milchwerke Oberfranken West eG<br />
has been a leading international<br />
manufacturer of fine cheese<br />
speciali ties for many years now<br />
and its products are becoming ever<br />
more popular around the world.<br />
Production, which has been constantly<br />
growing for years, requires<br />
a reliable source of premium-quality<br />
compressed air around the clock,<br />
seven days a week. This state-of-theart<br />
company has been using remote<br />
monitoring for some time now,<br />
which is a service package that not<br />
only ensures smooth compressed<br />
air supply, but also makes costs<br />
fully predictable at a fixed price over<br />
multiple-year terms.<br />
The delivered milk – separated according<br />
to type – is purified, pasteurised,<br />
cooled and subsequently stored<br />
in tanks. From there, it passes into the<br />
production stage. Prior to processing,<br />
the milk is heated and enriched with<br />
cheese-specific cultures, depending<br />
on the intended type of cheese being<br />
manufactured. Only then does<br />
the actual cheesemaking process begin.<br />
Once complete, 60 different varieties<br />
leave the company, including<br />
hard cheese, soft cheese, mozzarella<br />
and ready meals such as baked and<br />
grilled cheese products. 70 percent of<br />
the cheese stays in Germany and customers<br />
include all major retail chains;<br />
the rest is exported throughout the<br />
world, from China to Canada.<br />
As in many industrial production<br />
facilities, compressed air is essential<br />
for almost every application<br />
Milchwerke Oberfranken processes<br />

Production runs around the clock in<br />

stringent food-industry quality<br />
standards. Accordingly, the compressed<br />
air supply must also be of a<br />
suitably high quality.<br />

conditions analysed in order to<br />
gain an overall picture of the operation.<br />
The Sigma Air Manager “learns”<br />
the behaviour of the compressed air<br />
system, including the reaction times<br />
of the individual components, and<br />
uses this “knowledge” in the event of<br />
fluctuating consumption to adjust the<br />
compressed air supply to the most<br />
energy-efficient operation possible,<br />
based on past experience and the<br />
measured values available. Here, the<br />
master controller is also guided by<br />
the required pressure – i. e. the network<br />
pressure actually required by<br />
the customer at the air station outlet.<br />
The controller endeavours to maintain<br />
this pressure as low as possible,<br />
whilst at the same time ensuring that<br />
it does not drop below the minimum<br />
permissible value.<br />
If remote monitoring is used, the<br />
controller simultaneously transmits<br />
operating, service and energy performance<br />
data from the compressed<br />
air system to the service provider’s<br />
data centre. In this instance, the dairy<br />
plant works in close partnership with<br />
Kaeser Kompressoren. The service<br />
provider’s data centre contains a<br />
“digi tal twin” of the customer air station,<br />
which identically mirrors the actual<br />
station and, thanks to data transfer,<br />
is constantly updated in real time,<br />
rently responsible for ensuring reliable<br />
operation of the dairy-production<br />
facility in Upper Franconia. Compressed<br />
air is used for everything<br />
from delivery right through to the industrial<br />
wastewater treatment plant.<br />
Unsurprisingly, a highly reliable and<br />
economical supply of dry, technically<br />
oil-free compressed air is essential,<br />
with even higher-quality sterile<br />
air being required in the maturing<br />
rooms. Due to the high and constantly<br />
growing demand, the systems almost<br />
always run at high load. The<br />
stations were kept in peak condition<br />
by the compressed air systems provider<br />
for a long time on the basis of a<br />
classic maintenance contract. In 2021<br />
however, the dairy plant decided to<br />
switch to the very latest maintenance<br />
concept: remote monitoring.<br />
This was possible because the<br />
dairy plant’s compressed air station<br />
was already centrally controlled by<br />
an advanced master compressed air<br />
management system. Such a system<br />
is an optimal prerequisite to enable<br />
users to benefit from all of the advantages<br />
that Industrie 4.0 services<br />
have to offer. This master controller<br />
constantly monitors and evaluates<br />
compressed air generation and<br />
always selects the most efficient solution<br />
for the respective needs of the<br />
business in everyday operation. It<br />
achieves this by collating and analysing<br />
all operating data from the components<br />
in the system; not only the<br />

Compressed air remote monitoring<br />
Fig. 6: Data are transmitted to the service provider via the advanced master controller<br />
(Sigma Air Manager). The service technician performs demand-optimised maintenance.<br />
monitored and analysed for any further<br />
requirements. Data transmission<br />
is encrypted in real time via a<br />
proprietary network that is specially<br />
developed for this purpose. Access<br />
to the operator’s network is therefore<br />
not required to perform this task.<br />
The service package offers many<br />
advantages. With a classic maintenance<br />
contract, service technicians<br />
are scheduled to make visits and perform<br />
certain checks at fixed intervals.<br />
With remote monitoring, thanks to direct<br />
insight into station performance<br />
data, maintenance is performed on<br />
a system-specific basis according to<br />
actual system status. Maintenance<br />
is therefore needs-based and takes<br />
place only when actually necessary.<br />
This is where the provider’s expertise<br />
comes into play to facilitate predictive<br />
maintenance. Through the availability<br />
of the compressed air system’s<br />
process data and the resulting analysis,<br />
it is possible to determine the ideal<br />
time to implement maintenance<br />
work. Consequently, necessary service<br />
measures are recognised early<br />
on and can be carried out in a timely<br />
manner as required. This not only reduces<br />
downtime and increases energy<br />
efficiency, but also saves time and<br />
money. This combination of remote<br />
diagnostics and needs-based, preventative<br />
maintenance ensures maximum<br />
dependability for the operator’s<br />
compressed air supply.<br />
Maintenance costs can also be<br />
significantly reduced. With a classic<br />
Fig. 7: If a station is being serviced, the relevant<br />
compressors can be bridged externally<br />
using a portable compressor.<br />
maintenance contract, the operator<br />
bears all of the costs incurred, even<br />
if a major repair is needed. With the<br />
remote monitoring model, the operator<br />
pays a fixed service rate per<br />
year based on the actual volume of<br />
compressed air generated. All costs<br />
for maintenance and any repairs, regardless<br />
of the amount, are borne by<br />
the service provider. The service rate<br />
is fixed for five years, so that the operator<br />
knows exactly what to expect<br />
and is able to plan precisely, regardless<br />
of potential market price increases<br />
or actual repair costs.<br />
In addition to these maintenancerelated<br />
aspects, remote monitoring<br />
also provides further benefits for<br />
compressed air station operators.<br />
Since data are transmitted live and<br />
constantly monitored and analysed,<br />
the key figures generated will quickly<br />
show if a business’ compressed air<br />
demand should change. The smart<br />
service package includes monitoring<br />
of key figures such as service costs,<br />
reserve levels and specific package<br />
input power. When an operation<br />
grows, so too does its compressed<br />
air consumption. When this happens,<br />
it may be that the existing air station<br />
soon reaches the limit of its capacity,<br />
whereby the back-up compressors installed<br />
for reserve must be operated<br />
constantly. Or indeed the reverse<br />
may be the case; e. g. due to a change<br />
in production processes, a company’s<br />
compressed air consumption actually<br />
drops. Constant data monitoring<br />
identifies such developments early<br />
on, giving the operator the opportunity<br />
to verify the need for any expansion<br />
or investment plans they may<br />
have in good time.<br />
Furthermore, remote monitoring<br />
makes energy and life-cycle management<br />
possible throughout the air station’s<br />
entire service life. Up-to-date<br />
key energy management figures from<br />
a single source provide the basis for<br />
energy management in accordance<br />
with ISO 50001.<br />
In contrast to so-called “Contracting”,<br />
where the service provider<br />
makes the air system available and<br />
the user only purchases the compressed<br />
air that is used, with this service<br />
package the operator continues<br />
to be the owner of the compressed<br />
air station. After almost a year, the<br />
dairy plant is highly satisfied with the<br />
new service model. Based on past experience,<br />
the company is more than<br />
confident that it made the right decision<br />
in terms of economy, reliability<br />
and safety.<br />

How to protect pumps<br />
from air and gas inclusions<br />
New sensor technology for intelligent gas bubble<br />
detection prevents pumps from running dry<br />
Julian Budde<br />
When pumps fail, production stops,<br />
cooling systems are interrupted,<br />
and machines must be stopped.<br />
That is why effective pump protection<br />
is a crucial task for both plant<br />
engineers and technicians. It is particularly<br />
important to detect unwanted<br />
gas inclusions in fluid media<br />
at an early stage. This is remedied<br />
with a novel sensor technology detecting<br />
gas bubbles before they<br />
damage pumps.<br />
Fig. 1: By detecting gas bubbles in the supply pipe, the sensor protects pumps from running<br />
dry. (Photo: Baumer)<br />
Pumps are a key component to ensure<br />
consistent process flow where<br />
fluids are involved. They can be found<br />
virtually everywhere and are used to<br />
keep industrial processes moving forward,<br />
heat homes, and supply machines<br />
with lubricant. To ensure a<br />
process runs smoothly, pumps must<br />
be prevented from running dry and<br />
any cavitation must be identified, as<br />
both can lead to damage or failure.<br />
Dry running describes the situation<br />
that occurs when gas bubbles get<br />
into a pump and cannot be released.<br />
This means that there is too little or no<br />
fluid in the pump housing. One reason<br />
for this may be the improper commissioning<br />
of systems with, for example,<br />
an empty tank or closed suction pipe.<br />
Another may be the improper installation<br />
of pumps – if plant engineers do<br />
not pay sufficient attention to differences<br />
in height, this can lead to pump<br />
suction problems in the future.<br />
Possible damage caused by<br />
dry running<br />
So, what happens when pumps run<br />
dry? Depending on how quickly gas is<br />
detected in the pipes and on the volume<br />
of the gas inclusions, the effects<br />
may be more or less severe. At best,<br />
components are temporarily overloaded;<br />
in the worst-case scenario,<br />
the pump is destroyed. Dry running<br />
can cause, among other things, the<br />
following pump damage:<br />
– Considerable overheating of<br />
the bearings<br />
– Leakage due to destroyed sealing<br />
– Loss of performance, pressure<br />
loss, increased noise levels<br />
– Stiffness<br />
– Increased energy consumption and<br />
labor-intensive maintenance work<br />
– Complete destruction of the pump<br />
Bubble formation by cavitation<br />
Cavitation in fluid occurs when bubbles<br />
form on fast-moving objects or<br />
in constricted areas and dissipate<br />
again abruptly. This often occurs on<br />
ship propellers and in pumps and can<br />
cause considerable damage, or worst<br />
case, total failure. How does cavitation<br />
occur and why does it damage<br />
pumps? The reason behind cavitation<br />
is explained by Bernoulli’s principle<br />
stating that the faster a fluid moves,<br />
the lower its static pressure will be.<br />
When it comes to the fast-moving<br />
parts of a pump, the static pressure<br />
can even drop below the evaporation<br />
pressure of the fluid. If the static<br />
pressure falls below this threshold,<br />
gas bubbles form on these parts. As<br />
soon as the ambient pressure rises<br />
again as the flow continues, the gas<br />
bubbles implode loudly and cause vibrations.<br />
These implosions are characterized<br />
by high pressures which<br />
can damage or destroy the impeller<br />
and pump housing through pitting if<br />
they are not stopped in time. Cavitation<br />
does not only occur in pumps,<br />
but also in constricted areas of the<br />
supply pipes. This can also result in<br />
gas bubbles which damage the pump<br />
interior.<br />

How does gas get into pumps?<br />
There are various causes behind gas<br />
inclusions in systems. The most common<br />
reasons include:<br />
– Leakages<br />
– Leakages due to the manufacturing<br />
process (for example, when stirring<br />
and mixing ingredients and components)<br />
– Valves<br />
– Outgassing of media<br />
– Air pockets in the medium<br />
– Cavitation<br />
The more complex the system, the<br />
greater the likelihood of gas getting<br />
into pipes and pumps. Given the<br />
damage often associated with downtime<br />
and high maintenance costs, it<br />
would be ideal to detect gas in the<br />
system at an early stage. Reliable gas<br />
bubble detection provides the following<br />
benefits:<br />
Novel sensor detects even the<br />
smallest of gas bubbles<br />
To ensure effective pump protection,<br />
gas bubbles must be reliably detected<br />
before they enter the pump interior.<br />
No sensor was able to do this to<br />
date. The Baumer analysis sensor now<br />
closes this gap, which reliably detects<br />
even the smallest gas bubbles and air<br />
bubbles in the medium. Thanks to the<br />
smart sensor principle, it will immediately<br />
report any individually adjustable<br />
limit for gas inclusions being exceeded.<br />
The sensor measuring principle is<br />
dc-value based detection (dc = dielectric<br />
constant) of air and gas bubbles in<br />
fluids with a minimum conductivity of<br />
dc > 1.5. Thanks to sophisticated algorithms,<br />
the sensor will recognize very<br />
precisely any presence of gas and fluid<br />
in the flow. It measures independently<br />
of the medium, providing maximum<br />
flexibility. The “Gas bubbles in the medium”<br />
signal can be used to shut down<br />
the pump or report an alarm warning.<br />
The analysis sensor has its origins<br />
in the food industry. For years,<br />
dairy company Sachsenmilch GmbH<br />
was unable to completely empty the<br />
delivery containers containing an expensive<br />
fruit concentrate for the production<br />
of fruit yogurt. The problem<br />
was that if the yogurt manufacturer<br />
wanted to use nearly all the fruit concentrate,<br />
it ran the risk of gas pene-<br />
– Increased service life of pumps<br />
– Less maintenance and downtime<br />
– Increased system availability<br />
– <strong>Process</strong> safety<br />
– Higher product quality<br />
– System effectiveness and process<br />
efficiency<br />
– Cost reduction<br />
– Food safety in hygienic applications<br />
How have plant operators protected<br />
their pumps from harmful gas bubbles<br />
to date? In closed systems not<br />
allowing for visual inspection, operators<br />
can only guess at the presence<br />
of gas bubbles. Pump protection is<br />
therefore mostly based on acoustic<br />
monitoring – in other words, when<br />
an attentive technician hears something<br />
unusual. Given that machines<br />
suddenly generate much more noise<br />
when there is gas in the pumps, this is<br />
usually quite easy to detect.<br />
A sensor solution for detecting<br />
empty pipes has also been available<br />
for several years. A limit level sensor,<br />
which is embedded in the pipe<br />
from above, checks whether the pipe<br />
is filled with fluid or not. This method<br />
is primarily intended to provide the<br />
start-up signal for the pump as soon<br />
as it no longer draws gas, but only the<br />
fluid medium.<br />

trating the system which then had to<br />
be exhausted at great expense. For<br />
this reason, the company always left a<br />
safety reserve of the expensive ingredient<br />
in the container when changing<br />
containers. Working together<br />
with Sachsenmilch GmbH, Baumer<br />
developed the solution, which is ideal<br />
for protecting pumps. At the dairy<br />
company, the analysis sensor detects<br />
air and gas bubbles in the pipe system,<br />
pinpointing the imminent emptiness<br />
of the container and defining<br />
the best point in time for exchanging<br />
containers.<br />
The benefits for Sachsenmilch<br />
GmbH can be quantified precisely.<br />
By completely emptying the transport<br />
containers, the dairy company<br />
can use up to 8 kilograms more fruit<br />
concentrate per product type and<br />
production line than before. What’s<br />
more, the company can produce up<br />
to an extra 10000 cups of yogurt.<br />
This is because the sensor prevents<br />
the 15-minute downtimes that used<br />
to be required for cleaning and reconditioning<br />
the system when the<br />
container was empty.<br />
Ideal for the food industry and<br />
heating/cooling systems<br />
Wherever fluids are moved in closed<br />
systems, the analysis sensor can protect<br />
pumps from air and gas: in industrial<br />
applications, food production,<br />
building technology, or water<br />
supply. More target applications include<br />
monitoring cooling circuits and<br />
dry run prevention, process monitoring<br />
and ensuring process safety in<br />
terms of pump protection. The application<br />
is particularly beneficial for the<br />
food industry and in heating/cooling<br />
systems. In heating systems, a similar<br />
phenomenon happens right at home.<br />
When there is air in the system,<br />
household radiators do not properly<br />
heat up and energy is wasted. This<br />
is even more true for industrial heating<br />
and cooling systems. Gas bubble<br />
detection therefore ensures both resource-efficient<br />
operation and system<br />
effectiveness. <strong>Process</strong> safety and<br />
pump service life are increased, while<br />
the maintenance effort is reduced.<br />
In industrial applications, functioning<br />
pumps are all the more important<br />
because downstream processes can<br />
also be jeopardized if a failure occurs.<br />
In food production, unwanted gas<br />
bubbles in the system are particularly<br />
problematic because they can endanger<br />
not only the pumps but also food<br />
safety. This is because contact with<br />
air or gas during processing, filling,<br />
or packaging can have a direct impact<br />
on the quality of the food produced.<br />
In this scenario, early gas detection<br />
can reduce waste and increase system<br />
efficiency.<br />
The analysis sensor is particularly<br />
suited to protecting centrifugal<br />
pumps, gear pumps, and piston<br />
pumps.<br />

Pure and affordable drinking water<br />
for a whole region<br />
Sliding gate valves are optimising Belgium’s largest facility<br />
for RO water purification<br />
Veolia Water Technologies has built<br />
an ultra-modern plant to produce<br />
drinking water in Ostend, Belgium.<br />
In a multi-stage filtration process,<br />
the local water supplier is now producing<br />
drinking water of excellent<br />
quality – far above the statutory<br />
requirements. At critical points of<br />
the process – during reverse osmosis,<br />
filtration with activated carbon<br />
and remineralisation of the water<br />
– sliding gate valves made by<br />
Schubert & Salzer Control Systems<br />
are responsible for regulating pressure<br />
and flow rate.<br />
The water supplier, FARYS, produces<br />
drinking water for the city of Ostend<br />
and its surrounding area from<br />
the brackish water in the Bruges-<br />
Ostend Canal. In the current development<br />
stage of the waterworks built<br />
by Veolia Water Technologies, up to<br />
1,200 cubic metres of drinking water<br />
per hour can be fed directly into the<br />
pipe network. The plant constructed<br />
by the leading specialist for water<br />
Fig. 1: One DN125 and one DN50 sliding<br />

reverse osmosis units. (Photo © : Schubert &<br />
Salzer Control Systems)<br />
Fig. 2: In reverse osmosis, microcontaminants<br />
down to particle sizes of 0.1 nanometres<br />
are filtered out of the water. The<br />
fine-pored, semi-permeable filter layers are<br />
rolled up in pressure tubes.<br />
treatment is the largest Belgian drinking<br />
water production facility using<br />
RO technology and the production<br />
speed is among the fastest in the<br />
world. It is also unique that the installation<br />
can be used very flexibly within<br />
a variety of canal water qualities and<br />
that the entire process is done within<br />
consider ably reduced energy costs.<br />
The project manager of Veolia<br />
Water Technologies Belgium, describes<br />
the process as follows: “The<br />
canal water is treated in eight stages.<br />
First, in coarse, fine and microfiltration,<br />
all suspended particles, microbiological<br />
substances and pathogenic<br />
microorganisms are removed. During<br />
the subsequent reverse osmosis,<br />
fine-pored, semipermeable membranes<br />
filter microcontaminants up<br />
to particle sizes of 0.1 nanometre as<br />
well as minerals and salts.” Only water<br />
molecules remain. This water is<br />
sent through activated carbon filters<br />
and after injection with carbon<br />
dioxide, remineralised with limestone.<br />
Finally, the water is disinfected<br />
with UV light and then chlorinated.<br />
The result – drinking water of the<br />
highest quality – is fed into the pipe<br />
network via buffer storage tanks.<br />
“The operator of the waterworks<br />
wanted a facility that works cost-<br />
effectively. Maximum energy efficiency<br />
was required everywhere – even at<br />
the control valves”, explains the International<br />
Sales Manager at Schubert &<br />
Salzer Control Systems. “Equally, reverse<br />
osmosis and the subsequent<br />
process stages are demanding applications.<br />
There are special requirements<br />
here in terms of the control<br />
accuracy and reaction speed of the<br />
valves used.”<br />
Sliding gate valves provide effective<br />
protection against damage<br />
“During the reverse osmosis process,<br />
precise and fast pressure regulation<br />
is very important”, emphasises the<br />

eight activated carbon filters (pictured here) and 13 remineralisation tanks are<br />

Veolia engineer. “The highly sensitive<br />
filtration layers are rolled<br />
up in pressure pipes. Pressure<br />
shocks and excessive flow quantities<br />
have to be reliably prevented.<br />
Even the slightest overshoots<br />
in the control process could damage<br />
the expensive membranes.<br />
That is why we use one DN125<br />
and one DN50 sliding gate valve<br />
in each of the twelve reverse osmosis<br />
units. They ensure the exact<br />
regulation of the high process<br />
pressures that are ne cessary to<br />
compensate for the osmotic pressure<br />
of the brackish water and<br />
keep the reverse osmosis going.<br />
The decisive factor for the<br />
high precision and extremely<br />
short response time of the sliding<br />
gate valves is their special design<br />
principle. The sliding gate technology<br />
controls the flow rate in<br />
milliseconds, by two slotted sealing<br />
discs arranged vertically to<br />
the direction of flow moving on<br />
top of each other. The pneumatic<br />
actuator only has to overcome<br />
the sliding friction between the<br />
two discs. This means that the<br />
required actuating force is up to<br />
90 per cent less than on other<br />
types of valves. The actuators can<br />
be dimensioned consider ably<br />
smaller and the need for control<br />
air can be reduced. Simultaneously,<br />
the short strokes of only a<br />
few millimetres and the reduced<br />
kinetic masses of the throttle element<br />
protect the actuator and<br />
the spindle seal.<br />
Material and energy efficiency<br />
help overall cost-effectiveness<br />
The special design principle of<br />
the sliding gate valves has a double<br />
positive effect on the weight<br />
and dimensions. On the one<br />
hand, the valves are smaller and<br />
lighter due to the intermediate<br />
flange design and the smaller actuators.<br />
On the other hand, the<br />
significantly better flow properties<br />
due to the particularly high<br />
KVS values also allow the use<br />
of smaller nominal sizes, which<br />
makes these valves even more<br />
compact and lighter than common<br />
alternative solutions. Hence<br />
the 45 sliding gate valves in the<br />
plant weigh just 1,100 kilograms<br />
altogether. Seat valves in comparison<br />
would weigh in at around<br />
5 tonnes. This difference is considerable<br />
and, due to the savings<br />
on resources and CO 2<br />
, has positive<br />
effects over the valve’s entire<br />
life cycle – from manufacture to<br />
transport through to its operation<br />
in the plant. The maintenance<br />
and hence the operating<br />
costs are also reduced because<br />
of the more compact dimensions<br />
and low weight.<br />
The long service lives of the<br />
sliding gate valves were also a decisive<br />
point. These result, among<br />
other things, from the fact that<br />
they neutralise the damaging effects<br />
of cavitation. In alternative<br />
globe valves, imploding cavitation<br />
bubbles often cause cost-intensive<br />
wear due to erosion. Due<br />
to the special design of the sliding<br />
gate valves without flow deflection,<br />
the cavitation bubbles<br />
implode clearly behind the valve<br />
in the pipeline. This can easily be<br />
designed so that no damaging effect<br />
arises from the cavitation.<br />
Fig. 5: Size comparison between a normal seat valve and a sliding gate valve. In<br />
the example, the nominal size of both valves is identical.<br />
For this purpose, it is sufficient to<br />
run the pipe straight for a short<br />
distance after the valve. The control<br />
valves remain more or less<br />
untouched even in case of water<br />
shocks. The force of any water<br />
shock occurring in the pipework<br />
is not transferred to the actuator<br />
for the sliding gate valves, meaning<br />
that this cannot be damaged<br />
by pressure spikes.<br />
Even utilisation due to<br />
high-precision positioners<br />
“Before the treated water is fed<br />
into the region’s pipe network,<br />
we use DN150 sliding gate valves<br />
during the activated carbon filtration<br />
and remineralisation with<br />
limestone and CO 2<br />
”, adds the Project<br />
Manager. Here too, the supplier’s<br />
high-precision positioners,<br />
combined with the sliding gate<br />
valves, guarantee extremely accurate<br />
flow control, such that<br />
the eight activated carbon filters<br />
and 13 remineralisation tanks<br />
are evenly utilised. In this application,<br />
a linear flow characteristic<br />
curve proves to be particularly<br />
suitable for the regulation of the<br />
flow quantities to keep the process<br />
stable.<br />
Reliable, regional water supply<br />
guaranteed<br />
With an average output of 24,000<br />
cubic metres per day, the plant<br />
makes an important contribution<br />
to the reliable and cost-effective<br />
supply of drinking water to the<br />
people in the Ostend region.<br />
Periods of water shortage – as<br />
Belgium has experienced in the<br />
past summers and which will become<br />
even more frequent due to<br />
climate change - will be avoided in<br />
the future. For this reason, FARYS<br />
is already planning a second similar<br />
plant in Nieuwpoort.<br />

Operation under high pressure<br />
Specially adapted automatic basket strainer<br />
for pressures up to 1,160 psi (80 bar)<br />
Ulrich Latz<br />
In a hydroelectric power plant of the<br />
Swiss energy company Kraftwerke<br />
Oberhasli AG, specially modified<br />
Eaton automatic basket strainers<br />
minimize the wear on the hydraulic<br />
control valves caused by glaciers<br />
and suspended solids. They are designed<br />
for water pressures of up to<br />
1,160 psi (80 bar) and filter out particles<br />
with a fineness of 25 μm.<br />
the runoff into the reservoir and collect<br />
there together with other suspended<br />
matter brought in by rainfall.<br />
These 25 to 200 micron particles pose<br />
a problem for the huge turbines in<br />
the KWO power plants, as they cause<br />
heavy wear of the slide valves. These<br />
valves use the pressure of the water to<br />
control the ball valves which, in turn,<br />
control the intake to the turbines. Due<br />
sis, but now they are no longer available<br />
on the market. In order to reduce<br />
or, ideally, eliminate costly and<br />
time-consuming repairs, the hydroelectric<br />
power plant operator was interested<br />
in finding a new solution.<br />
“The installation of larger settling<br />
tanks was not an option,” continues<br />
the manager. “At water pressures of<br />
870 psi (60 bar), 1,160 psi (80 bar) or<br />
even more than 1,450 psi (100 bar),<br />
very large and complex tanks would<br />
be needed. But that would not be feasible<br />
for economic and environmental<br />
reasons, and for lack of space. Converting<br />
to oil hydraulics was likewise<br />
not feasible for the same reasons.”<br />
Therefore, KWO decided to install<br />
filter systems directly upstream of<br />
the control valves and turned to BT-<br />
Hydraulik, a leading company in the<br />
field of hydraulic drive technology.<br />
The experts from the Bernebased<br />
company advised KWO to use<br />

The Kraftwerke Oberhasli AG power<br />
plant (KWO) can generate energy<br />
on demand at any time using water<br />
dammed in the Grimselsee, 1909 meters<br />
above sea level. The Swiss energy<br />
company makes an important contribution<br />
to generating electricity and<br />
stabilizing the grid in Switzerland and<br />
Europe from its hydroelectric power<br />
plants in the Grimsel area. In addition,<br />
reservoirs act as natural batteries<br />
in which energy can be stored in<br />
the form of water and later used to<br />
generate electricity. However, the use<br />
of natural glacial runoff and rainwater<br />
poses a problem-suspended matter.<br />
The glacier is continuously eroding<br />
very fine stone particles from the<br />
mountains. These solids, derived from<br />
glacial abrasion, are transported by<br />
to the water’s drop height of 670 meters,<br />
very high pressures occur in the<br />
valves and their supply lines.<br />
Heavy wear on hydraulic<br />
control valves<br />
Sand settling tanks are in place upstream,<br />
which prevent the entry<br />
of coarse particles into the control<br />
valves, however they have demonstrated<br />
only limited success. “Until<br />
now, the valves had to be cleaned and<br />
repaired by the KWO every three to<br />
four months,” explains the Sales and<br />
Technical Manager at BT-Hydraulik<br />
AG, which was commissioned by KWO<br />
to find a solution to the problem. In<br />
the past, the valves even had to be<br />
completely replaced on a regular ba-<br />

Valves<br />
need to be serviced and replaced at<br />
regular intervals. An automatically<br />
self-cleaning filter is the more economical<br />
solution. The problem is that<br />
standard backwash filters are not designed<br />
for the high pressures in a hydroelectric<br />
power plant. BT-Hydraulik,<br />
together with Eaton, continued<br />
to work on refining the strainer. This<br />
motor-driven strainer provides continuous<br />
removal of solids from fluids<br />
in pipework systems - though only<br />
within a standard pressure range up<br />
to a maximum of 232 psi (16 bar).<br />
However, the supplier provides customization<br />
of this filter system to<br />
serve customer-specific applications.<br />
Modified automatic basket<br />
strainer withstands pressures up<br />
to 1,160 psi (80 bar)<br />
A version of the automatic basket<br />
strainer was developed for KWO<br />
that is designed for pressures of up<br />
to 1,160 psi (80 bar). However, a variety<br />
of measures were required to<br />
make this possible: First of all, in order<br />
to withstand the high pressures,<br />
Eaton modified the entire housing<br />
by increasing the wall thickness and<br />
making the cover considerably sturdier.<br />
In addition, the flushing arm<br />
drive shaft was sealed with a quadruple<br />
mechanical seal. A particularly<br />
challenging problem was to find<br />
a filter element that offers the highest<br />
possible filter fineness that could<br />
also withstand the high pressures<br />
and was backwashable. A reinforced<br />
version of the DuraWedge ® filter elements<br />
proved the solution: Made of<br />
V-shaped stainless steel wire profiles,<br />
even the standard version is capable<br />
of being used in demanding applications.<br />
After being further reinforced,<br />
they now can withstand the high pressures<br />
in the hydroelectric power plant,<br />
filtering out a large part of the suspended<br />
matter due to a filter fineness<br />
of 25 μm. The system had to be ad-<br />

ditionally adjusted so that the screen<br />
baskets would not be deformed in the<br />
backwash phase. A pressure reduction<br />
of 870 psi (60 bar) to the ambient<br />
pressure would have been problematic<br />
despite the reinforcement.<br />
The high-pressure basket strainers<br />
used in KWO’s hydroelectric power<br />
plant – so far there are four – have<br />
also been adapted to the operating<br />
parameters used there. The connector<br />
size for two of the filters is<br />
2 inches and for the other two is<br />
3 inches, with a flow rate of between<br />
53 and 106 gallons per minute (200<br />
and 400 liters per minute). How ever,<br />
the design of the high-pressure strainer<br />
basket developed jointly by Eaton<br />
and BT-Hydraulik can also be adapted<br />
to other parameters – in line with<br />
whatever the application requires. The<br />
backwash is triggered by a control – in<br />
KWO’s case, whenever the differential<br />
pressure reaches 11.6 psi (0.8 bar). Alternatively,<br />
control using predetermined<br />
time intervals or permanent<br />
backwashing would also be feasible.<br />
Wear and repair costs significantly<br />
reduced<br />
Even though the test phase of the<br />
new filter system is scheduled to run<br />
for several years, initial results are<br />
already clear. “The results are very<br />
good,” says KWO. “So far we have<br />
had no outages and the system perfectly<br />
meets our needs in terms of<br />
maintaining and cleaning the baskets.”<br />
Especially compared to the<br />
turbine lines where the sliding gate<br />
valves have not yet been retrofitted,<br />
it is clear that wear and tear has been<br />
significantly reduced – the amount of<br />
maintenance required and the associated<br />
costs have been minimized by<br />
the high-pressure automatic basket<br />
strainer.<br />

Every pneumatic actuator in the actubar ® series is now equipped<br />
with the additional pneumatic interface of the bar-vacotrol ® system<br />
as standard. The openings of the pneumatic air duct as a direct connection<br />
between actuator and control unit are closed with a blow-outproof<br />
and reusable screw. When retrofitting control units from the<br />
bar-vacotrol ® series, only the screw plug is unscrewed from the actuator<br />
housing to open the direct connection. The control unit can be<br />
mounted directly and put into operation.<br />
bar-vacotrol ® as an integrated air duct realises an increased level in<br />
the reduction of interfaces between actuator and control unit and is<br />
predestined for an optimal realisation according to VDI/ VDE 3847-2.<br />
The suitably developed generation of control components makes external<br />
piping unnecessary, is easily accessible and logical to operate.<br />
This applies to the bar-positrol ® and bar-positurn2 positioners as well<br />
as to the bar-posiswitch ® and bar-valve&switch ® limit switch boxes.<br />
Thus, devices with internal as well as external solenoid valves can be<br />
selected for more flexibility in adapting to the installation situation and<br />
environment.<br />
In the 4 largest actubar ® actuators of the 18 available sizes, the solenoid<br />
valve interface can be flexibly adjusted to ¼" or ½" air flow with<br />
additional mounting plates, which also achieves better adaptation to<br />
existing process conditions.<br />

BOGE at the <strong>2023</strong> Hanover Trade Fair<br />
Increasing efficiency of<br />
compressed air systems with<br />
digital transformation<br />
Smart compressed air management in the age of Industry 4.0 – at the<br />
Hanover Trade Fair, BOGE will show how compressed air systems can<br />
easily be analysed and optimised using BOGE connect. The smart service<br />
tool has been expanded with additional connection options and is<br />
therefore even more versatile. Trade fair visitors can find out for themselves,<br />
thanks to the C 14 PM screw compressor on display.<br />
A constant overview of all operating data – BOGE connect records,<br />
monitors and visualises all important parameters, thus significantly<br />
simplifying administrative work. All relevant data is saved in a digital<br />
machine file. Continuous monitoring allows conclusions to be drawn<br />
regarding the device’s status at all times. Anomalies can be detected<br />
and malfunctions fixed early, thanks to data analysis. BOGE connect<br />
will provide timely automatic reminders of upcoming maintenance<br />
or servicing. Data can be retrieved in real-time from anywhere and is<br />
available on all mobile end devices.<br />
Clean business: Pipe-free connection with bar-vacotrol ® .<br />
Advantages<br />
Emissions due to leakage are minimized by eliminating susceptible<br />
pneumatic fittings and the small number of robust sealing points. There<br />
is no dead volume in lines. <strong>Process</strong> operation is less susceptible to faults<br />
and less sensitive to vibrations. External influences lead to damage<br />
and failures much less frequently. This results in longer running times<br />
and higher availability for the systems. When changing components,<br />
the modular system makes adjustments to pipelines super fluous. The<br />
changeover process of components can be easily integrated into the<br />
workflows and assembly times are considerably reduced.<br />
New connection options<br />
Thanks to numerous interfaces, even older models and products from<br />
other brands as well as various components can be connected. The re-<br />
NAMUR+<br />
In addition, a new adapter plate has been developed with which the<br />
NAMUR interface can be an extension to the Namur+ connection. Solenoid<br />
valves with NAMUR+ interface can be screwed onto the free flange<br />
surface of the adapter plate. Connections for supply compressed air,<br />
control air and venting are easily accessible from the side. Assembly or<br />
replacement is possible without having to tighten and seal the pneumatic<br />
fittings.<br />

vised version features new interface modules 2.0 for the connection of<br />
compressors and loose as well as built-in accessories. Additional Modbus<br />
TCP components can be connected using the 5-way switch with<br />
four free Ethernet ports. Overall, BOGE connect, in the bigger switch<br />
cabinet version, now offers more space for modules and therefore optimised<br />
connection options. Visitors to Hannover Trade Fair can test<br />
the comprehensive functions of the advanced service tool using the example<br />
of the C 14 PM screw compressor. The compact compressor is<br />
equipped with a permanent motor and, even by itself, delivers incredible<br />
performance, combined with a very low noise level. However, with<br />
BOGE connect, performance can be increased again. Seamless reporting<br />
across the entire life cycle ensures low operating costs, maximum<br />
planning reliability and maximum efficiency. The service tool, as an industrial<br />
IoT platform, paves the way for future smart services such as<br />
predictive maintenance.<br />
At Hanover Trade Fair, BOGE experts will report on current trends<br />
in technology and support at Booth D27 in Hall 7 from 17 th to 21 st April.<br />

Hydrogen on the rise – from small<br />
projects to large-scale plants<br />
Fig. 2: High pressure safety valves for technical gases up to 1500 bar<br />
Hydrogen has long since become our focus. Initially, we supplied fittings<br />
for small projects, but now we also supply large plants.<br />
The initial situation is clear: a way is needed to make electricity from<br />
renewable sources storable. The technology required for this ranges<br />
from electrolysis to pure hydrogen and oxygen to the production of<br />
ammonia and synthetic hydrocarbon compounds produced with PtX<br />
processes. Fittings are needed for all these processes.<br />
Well prepared<br />
We are well prepared and have qualified our product range for use<br />
with the medium hydrogen. This ranges from specific material testing<br />
to the fulfilment of special standards for seals. Especially for the application<br />
for storing high-pressure hydrogen, we have significantly expanded<br />
the possibilities in production with new test benches.<br />
As a manufacturer of safety valves, pressure reducing valves and<br />
overflow valves, Goetze products are used in almost all areas of the<br />
hydrogen value chain - from generation via electrolysis or other thermal<br />
processes and via storage at high pressures or cryogenic liquefied<br />
up to the point-of-use at the end user. We regulate the pressure before<br />
electrolysis, secure the feedwater pump circuit and ultimately the<br />
tanks for storing the hydrogen against impermissible overpressure.<br />
Employees already trained<br />
The hydrogen industry needs suitable fittings, for which certain materials<br />
are to be used. We focus in particular on stainless steels with a higher<br />
nickel content, for example, to prevent hydrogen embrittlement. For<br />
seals, compliance with certain standards is important. The very small<br />
H 2<br />
molecule can accumulate in sealing materials, penetrate them and<br />
destroy them from the inside. The seal must therefore be manufactured<br />
and specially tested with this in mind.<br />
We do not see the use of hydrogen as a challenge, but rather the way<br />
to get there, in order to have it widely available as quickly as possible. Internally,<br />
we are looking at proven designs that we can improve and optimise<br />
for hydrogen applications and realise with high-quality, tested materials.<br />
Our employees have already been trained on this topic.<br />
Valves get bigger<br />
As a company, we are globally positioned, but we see a focus in Europe,<br />
due to the lack of gas from Russia.<br />
Like the markets, the hydrogen projects are also growing. While<br />
pressures of up to 350 bar were common in the past, the valves are<br />
now required for significantly higher pressures, e. g. protection against<br />
overpressure in vehicle refuelling systems for 700 bar. Here, our Goetze<br />
valves protect the system components at up to 960 bar. We could<br />
go even higher. An end? Not in sight...<br />

ChemBall - A revolution in PFA-lined<br />
ball valves<br />
The PFA-lined ball valve ChemBall is the new flagship of the Swiss company<br />
ChemValve-Schmid AG. The TrueFloat ® technology, developed<br />
in-house and patented worldwide, is revolutionary and strict on-site<br />
production ensures that this ball valve always bears the hallmark<br />
“Swiss Made”.<br />
ChemValve-Schmid AG, based in Welschenrohr, Solothurn is synonymous<br />
with insourcing instead of outsourcing. The independently<br />
owned company is a leading European manufacturer of PTFE-lined<br />
butterfly valves. Continuous research and development is the driving<br />
force behind the company and its production, the most recent example<br />
being the ChemBall.<br />
Maiden voyage of the flagship<br />
The first prototypes of the ChemBall were delivered to a European textile<br />
fibre manufacturer in October 2020 in a unique venture. After a<br />
two-year test phase, the product specification was successfully completed.<br />
Today, the ChemBall is also on sale throughout North America<br />
and Asia.<br />
PFA-lined ball valve ChemBall<br />
The PFA-lined ball valve ChemBall is based on the TrueFloat ® technology<br />
developed and patented in-house. Specifically, this means that a<br />
single-piece PFA jacket encloses the floating ball stem, which is able to<br />
move within itself. The ball is suspended by means of a metal-to-metal<br />
connection, which eliminates wear. The result is maximum tightness<br />
combined with an extended service life. The valve can be used in temperatures<br />
ranging from -20° C to 200° C. Whereas development and<br />
production initially focused in particular on the chlor-alkali industry,<br />
the further-developed ChemBall is ideal for use with all types of aggressive<br />
media.<br />
The ball valve is currently available in the EN sizes DN 25, 40, 50,<br />
80, 100 and 150 and in the ASME nominal diameters 1″, 1-1/2″, 2″, 3″,<br />
4″ and 6″. In the first half of <strong>2023</strong>, the product range will be expanded<br />
to include the nominal diameters DN 15, 20, 32 and 65.<br />
Swiss-made for shorter paths to success<br />
ChemValve-Schmid AG has outstanding expertise in PFA manufacturing.<br />
Dedicated PFA-injection-moulding machines have been specially<br />
developed for the production of these unique valves. Both metal and<br />
PTFE valves, such as the ChemBall, are developed, produced, tested<br />
and prepared for shipping in Dünnernstrasse 540, Welschenrohr,<br />
Switzer land. “We are a down-to-earth team, the decision-making process<br />
is short, and people find it easy to talk to us” says the managing director,<br />
Christoph Schmid. Despite a high workload, it only takes a short<br />
space of time from the quotation stage to production. The standard<br />
delivery time is four weeks. Every PFA ball valve and every PTFE butterfly<br />
valve from ChemValve-Schmid AG is given a unique “valve ID” so<br />
that it can still be clearly identified years later. Every product test and<br />
certificate is fully traceable.<br />
Join the Valve Revolution! Now!<br />
The declared objective of ChemValve-Schmid AG is to increase its presence<br />
in the German market. “As a medium-sized Swiss company that<br />
develops and produces valves itself, we are on the lookout for trade<br />
partners as well as end users. We welcome every contact” says Managing<br />
Director Christoph Schmid. He has been on board for around 17<br />
years now, but the flagship, the ChemBall, is new.<br />

The SAUER Orkan series is suitable for the compression of many gases<br />
and a variety of applications. The first standard types of the series are<br />
two high-pressure air compressors with a final pressure of up to 350 and<br />
500 barg respectively, a high-pressure helium compressor with a final<br />
pressure of up to 350 barg, and a high-pressure nitrogen booster with<br />
a final pressure of up to 350 barg and an inlet pressure of 4 to 8 barg.<br />
Next to developing completely new compressor platforms Compressors<br />
focuses on the enhancement and expansion of existing compressor<br />
series. The air-cooled series SAUER Hurricane is a good example<br />
for that. The new nitrogen boosters SAUER Hurricane WP4366LH<br />
B3-8 and WP4399LH B3-8 provide a final pressure of up to 350 barg<br />
and an inlet pressure of 3 to 8 barg. They are specially designed for the<br />
compression of nitrogen and are based on the robust platform of the<br />
series, that has proven itself under toughest operating conditions for<br />
years. The new launches complement Sauer Compressors’ portfolio of<br />

in Germany. The Series TRI-CON contains nominal<br />
sizes from 2” to 82” as well as pressure classes<br />
from Ansi 150 lbs to 1500 lbs. The check valves of<br />
the series TRI-CHECK are based on the same metal<br />
seated triple off-set design, equipped with counter<br />
weight and hydraulic damper. The Double Block and<br />
Bleed design features every technical advantage,<br />
which the series TRI-CON has, plus there is a true<br />
double block and bleed feature. TRI-SHARK control<br />
valves have excellent throttling characteristics and<br />
provide aerodynamic noise attenuation as well as a<br />
reduction of cavitation.<br />
