HF 760 - HF 761 series - Harrier Filters

THE IMPORTANCE OF AN EFFICIENT FILTRATIONThe main cause of anomalies in hydraulic systems has tobe attributed to the presence of contaminants in the fluid.The nature of the contaminant may be: gaseous, namelyair mixed with the fluid; fluid, in most cases it is water thathas penetrated the fluid; solid, therefore particles of variousorigins and dimensions.The customers who operate equipment are always focusedon obtaining the best possible performance, lowerenergy consumptions and greater respect for the environment.These characteristics can be attained by using top qualitycomponents in the hydraulic system for generatingand regulating the fluid power, which are however rathersensitive to the presence of contaminants in the fluid.Starting from these requirements, we understand howimportant and fundamental it is to prevent the presenceof air and water from mixing in the fluid tank by using dedicatedsolutions.It is also crucial to limit the presence of solid particles inthe hydraulic circuit through a suitable filtering system,which is indispensable to maintain the project requirementsof the system over time and to keep running costslow.The correct choice of a filter and its optimum position inthe hydraulic system requires the same care and experienceneeded to choose all the other components.The use of filters with larger filtering surfaces reduces, atequal flow rates, the superficial contaminant load andtherefore the filter's life is extended proportionally.To maintain the maximum efficiency of the system, the filtersmust have a clogging indicator showing the differentialpressure on the filtering cartridge and to immediatelypoint out when the cartridge needs replacing in order toprevent the by-pass valve from opening.The following factors should be analysed when choosing the ideal filter: The filtration degree required to protect the most sensitive component from contamination The points of the circuit in which the filters have to be installed The working pressure of the system The maximum flow rate and the type of fluid to be filtered The duty cycle The retention efficiency of the filtering cartridge The contaminant accumulation capacity of the filtering cartridge The working ambient temperatureEach filter used generates a pressure drop that increases continuously as time goes by. This pressure drop representsan efficiency index of the filter itself.When the hydraulic system is about to be assembled, all the components must be perfectly clean and the fluid has to beadded through a device complete with a filter.During the test phase, it is advisable to run some work cycles at low pressure in order to create the best possible conditionsfor all the components.

HF 760 - HF 761TECHNICAL CHARACTERISTICSThe filters of the HF 760 and HF 761 series are connectedto the pressure line of the circuit and protect thesystem’s components against contaminant particles.The standard filters are supplied with by-pass valve calibratedat 87 psi (6 bar).HF 761 serie differs from the HF 760 one because adoptsHE K-86 elements.For applications which need maximum protection of thesystem, such as servo drives or proportional controls, thefilters are equipped with highly resistant filtering elements(versions “HC”) and do not have a by-pass valve.

HF 760 - HF 761SIZING – PRESSURE DROPThe total pressure drop of the filter is calculated by summing the pressure drop value in the housing to the one filteringelement.Total p p in housing + p in elementIn filters of series HF 760 and HF 761 in normal working conditions, the total p must not be more than 11 psi (0,75 bar)whereas, for use in harsh conditions, it must be within 14.5 22 psi (1 1,5 bar).To establish the values of pressure drop involved, the following pages provide some diagrams with curves referred tothe use of mineral oils SAE 10 with kinematic viscosity of 120 SSU (30 cSt) and density of 7.29 lb/gal (0,856 kg/dm 3 ).Calculation exampleFilter HF760-20.106-AS-FG010-LC-B60-GD-B-DD-GFlow rate= 12 US gpm (45 l/min)Kinematic viscosity: 120 SSU (30 cSt)Oil density : 7.29 lb/gal (0,856 kg/dm 3 )Filtering degree: 10 mData obtained from the diagrams:p in housing = 2.00 psi (0,14 bar) (page 4)p in element = 7,25 psi (0,50 bar) (page 5)Total p = 2.00 + 7.25 = 9.25 psi (0,64 bar) (p is lower than maximum value admitted – therefore sizing is correct)..If oil with different kinematic viscosity and different density is used, the values obtained from the diagrams will be re-calculatedconsidering the following indications:1) The pressure drop of the housing is proportional with the oil density, therefore for oil with density different to 7.29lb/gal (0,856 kg/dm 3 ) the value of the p in the head-bowl will be:p in housing =Orp in housing =p of diagram (psi) • Oil density ( lb/gal)7.29 (lb/gal)p of diagram (bar) • Oil density ( kg/dm 3 )0,856 (kg/dm 3 )[psi][bar]2) The pressure drop of the element is proportional with the oil density and kinematic viscosity, therefore for oil with densitydifferent to 7.29 lb/gal (0,856 kg/dm 3 ) and kinematic viscosity different to 120 SSU (30 cSt) the value of p in the elementwill be:p element = p of diagram (psi) •Orp element = p of diagram (bar) •Oil density (lb/gal) Oil viscosity (SSU)•7.29 (lb/gal) 120 (SSU)Oil density (kg/dm 3 ) Oil viscosity (cSt)•0,856 (kg/dm 3 ) 30 (cSt)Now you sum the values of the pressure drop of the housing to the value of the pressure drop of the filtering element, alwaysmaking sure the total p does not exceed the pressure limit of 11 psi (0,75 bar).[psi][bar]03/01.20102 002 ICAT011-002

HF 760 - HF 761ASSEMBLY AND REPLACING ELEMENT INSTRUCTIONSASSEMBLYOnce you have checked the integrity of the filter inside its package,proceed as follows:ABCDEFSecure the filter to the attachment device via the threadedholes in the head (pos.6).Take the protection caps off the oil inlet and outlet.Connect the circuit pipes to the filter, checking the flow direction,which is pointed out by the arrow on the head(pos.6).If the clogging indicator (pos.9 - 10 - 11) is immediately mountedin the filter, take the protection cap off and screw theindicator in the dedicated seat and tighten to a tighteningtorque of 266 lbf in (30 Nm). If the indicator is electric, completethe required connections.Start the circuit for a few minutes.Make sure there are no leaks.REPLACING ELEMENTOnce the working hours limit indicated in the maintenance instructionsof the system is reached, or when the clogging indicatorspoint out the limit pressure drop created inside the filter, thecartridge must be replaced, remembering that this procedure involvesthe drainage of hydraulic oil and therefore you need toprepare suitable containers to collect the oil.Proceed as follows:ABCDEFGHIStop the system in “Machine stopped” status.Secure any shut-off valves on the hydraulic circuit.Unscrew the filter container (pos.1).Remove the clogged filtering cartridge (pos.5), makingsure no residual particles have settled on the bowl bottom(pos.1).Make sure the O-ring (pos.2 - 4) and the anti-extrusion ring(pos.3) are not damaged, otherwise replace them and consequentlyposition the new ones correctly.Insert the new filtering cartridge, lubricating the sealingO-ring beforehand.Screw the container tight (pos.1) making sure the threadingis screwed correctly. Tighten to a tightening torque asindicated on pages 9,10,11.Start the machine for a few minutes.Make sure there are no leaks.03/01.2010Pos.
