Technical innovation in mixing
and agitation processes
NORD MAXXDRIVE® industrial gear units
are an excellent choice for use in large
mixers. With the SAFOMI adapter, NORD
is presenting a technical innovation in
this field of application: a flange with an
integrated oil expansion tank, increasing
operational reliability and requiring fewer
wearing parts.
MAXXDRIVE® industrial gear units have
been part of the NORD product range
for more than ten years and have proven
themselves in countless applications
throughout the world. They offer high
output torques from 15 to 250 kNm and
ensure smooth operation even under
demanding conditions.
NORD MAXXDRIVE® industrial gear units
ensure reliable operation in industries
using mixing and agitation processes
even under extreme conditions. The FEMoptimised
and compact design enables
operation under ultimate external
loads. The extensive MAXXDRIVE®
modular system provides many options
for tailored solutions. For agitator
applications, the MAXXDRIVE® industrial
gear units can be equipped with a
SAFOMI IEC adapter. SAFOMI is the
abbreviation for Sealless Adapter For
Mixers.
This special IEC adapter combines the
functions of a standard IEC adapter
and an oil expansion tank in a single
component. SAFOMI is available for
parallel gear units and in the sizes 7 to
11, i.e. for maximum output torques from
25 to 75 kNm. The compact combination
of MAXXDRIVE® industrial gear units,
SAFOMI IEC adapter and drive motor is
the best choice for mixer and agitator
applications to reduce wearing parts and
attached components.
LESS EFFORT, MORE
OPERATIONAL RELIABILITY
The SAFOMI IEC adapter has a compact
and simple design, and is equipped with
an integrated oil expansion volume. Oil
tanks and hoses as well as the radial
shaft seal subject to leakage and wear
between gear unit and IEC cylinder
are not required. As standard, the
combination of parallel gear unit and
SAFOMI-IEC adapter is only installed
in installation position M5, i.e. with an
output shaft pointing downwards.
The change to an SAFOMI-IEC adapter
instead of the standard IEC adapter on
the agitator drive increases operational
reliability and lowers maintenance costs.
The oil level as well as the required oil
volume is lower and thanks to missing
attached components, the installation
space is also reduced.
NORD MAXXDRIVE Parallel Gear Units deliver high performance every day in heavy duty
applications such as agitators, mixers, drums or crushers
