3 These fluids should contain rust andoxidation inhibition, anti-wear, anti-foam, anddeaerating agents. For other fluid types, pleasecontact your Continental Application Operating ViscositiesFor petroleum based fluids: Optimum -- 140 sus (30 Cst.). Continuous Minimum -- 60 sus (10 Cst.). Continuous Maximum -- 750 sus (160 Cst.).Operating TemperatureThe operating temperature should be deter-mined by the viscosity characteristics of the fluidused. Because high temperatures degradeseals, reduce the service life of the fluid, andcreate hazards, fluid temperatures should notexceed 180 F. (82 C.) at the case Cleanliness ISO 16 line: To maintain the minimum pre-scribed cleanliness levels, a high quality returnline filter should be used. A filter with a 10micron rating is normally sufficient to start up asystem.

4 Because every system has uniquecharacteristics, this rating may need to bechanged. Periodic testing of fluid is highlyrecommended. The data collected from thesetests will tell if the current filter system is main-taining the cleanliness of the fluid to the ISO 16/13 Inlet PressureThe maximum inlet pressure is 50 PSI at PositionUnrestricted, however horizontal mounting Shaft AlignmentPump and motor must be within .003 inches( mm) TIR (Total Indicated Runout) for maxi-mum bearing CouplingJaw type with a flexible web is and Chain type couplings are not DrainAll HPV series Piston pumps have two casedrain ports. It is only necessary to connect acase drain line to one of these ports. The otherport is provided to fill the case with fluid on startup. All case drain lines should be as short aspossible with no restrictions or reduction in routing of the case drain line back to thereservoir must not allow the fluid in the case todrain back into the reservoir while the pump isnot in use.

5 This line should terminate below thesurface of the fluid in the reservoir. Please referto Continental Hydraulics HPV series installationand service literature for further ValvesSystem relief valves are recommended for allapplications to protect personnel and the systemfrom potentially damaging overloads. Thesevalves should be sized for the maximum flow ofthe pump and set approximately 200 psi abovethe pump compensator SERIESAXIAL Piston PUMPSPRESSURE COMPENSATED CONTROLThe standard pressure compensated control changesthe displacement of the pump to match the systemflow requirement by controlling the system stated: a pressure compensated pump willprovide variable flow at a constant pressure displacement of the pump is mechanicallycontrolled by the angle of the swashplate. Theswashplate angle is controlled by the extension of thecompensator plunger, which works against theswashplate bias spring.

6 The compensator senses thedownstream pressure and adjusts the displacementto maintain the set control would be used on systems where the flowrequirements are variable but the pressure require-ments are SERIESAXIAL Piston PUMPSREMOTE PRESSURE CONTROL (Code 7)this line may be controlled by one or more reliefvalves. These should be direct acting and capable ofpressures up to 3500 psi (241 bar). The setting ofthese relief valves will control the pressure setting ofthe control would be used on systems where theflow requirements are variable and multiple pressuresare remote pressure control works similar to thestandard pressure compensated control, with someadded features. This is a two stage compensatorwith two pressure adjustments: one for the lowerpressure limit and one for the upper pressure vent line* is required to run back to the this line is vented, the pump will go to the lowerpressure setting.

The adjustment on the back side will set theupper pressure limit. The adjustment on the front isused to set the pressure differential of the flow controlvalve. This setting comes preset to 250 psi ( ).This control can be combined with a variable flowcontrol (like a proportional valve) to deliver variableflow and variable pressure.* Maximum length of this line is 50 feet. Hard piping is recommended to maintain system SENSING CONTROL (Code 19)The load sense control is designed to deliver aconstant flow across an orifice and adjust the pres-sure to meet the system's demands.

8 This type ofcontrol is often called flow compensating. This isaccomplished by using a flow control valve betweenthe pump outlet and the sense line* must be connected between thedownstream side of the flow control and the pumpcompensator.
