Piston Pumps - General Specifications:Recommended FluidsFluids for use in these pumps should be petroleum based and designated by the fluid manufacturer for use in hydraulic systems. These fluids should contain rust and oxidation inhibition, anti-wear, anti-foam, and deaerating agents.Recommended Operating ViscositiesFor petroleum based fluids:· Optimum -- 140 sus · Continuous Minimum -- 60 sus · Continuous Maximum -- 750 sus Operating TemperatureThe operating temperature should be determined by the viscosity characteristics of the fluid used. Because high temperatures degrade seals, reduce the service life of the fluid, and create hazards, fluid temperatures should not exceed 180°F. (82°C) at the case drain.Fluid CleanlinessISO 16/13FiltrationReturn Line: To maintain the minimum prescribed cleanliness levels, a high quality return line filter should be used. A filter with a 10 micron rating is normally sufficient to start up a system. Because every system has unique characteristics, this rating may need to be changed. Periodic testing of fluid is highly recommended. The data collected from these tests will tell if the current filter system is maintaining the cleanliness of the fluid to the ISO 16/13 level.Maximum Inlet PressureThe maximum inlet pressure is 50 PSI at all speeds.Mounting PositionUnrestricted, however horizontal mounting is preferred.Drive Shaft AlignmentPump and motor must be within .003 inches (0.8 mm) TIR (Total Indicated Runout) for maximum bearing life.Drive CouplingJaw type with a flexible web is recommended. Tire and Chain type couplings are not recommended.Case DrainAll HPV series piston pumps have two case drain ports. It is only necessary to connect a case drain line to one of these ports. The other port is provided to fill the case with fluid on start up. All case drain lines should be as short as possible with no restrictions or reduction in size. The routing of the case drain line back to the reservoir must not allow the fluid in the case to drain back into the reservoir while the pump is not in use. This line should terminate below the surface of the fluid in the reservoir.Relief ValvesSystem relief valves are recommended for all applications to protect personnel and the system from potentially damaging overloads. These valves should be sized for the maximum flow of the pump and set approximately 200 psi above the pump compensator setting.Pressure Compensated ControlThe standard pressure compensated control changes the displacement of the pump to match the system flow requirement by controlling the system pressure. Simply stated: a pressure compensated pump will provide variable flow at a constant pressure setting.The displacement of the pump is mechanically controlled by the angle of the swashplate. The swashplate angle is controlled by the extension of the compensator plunger, which works against the swashplate bias spring. The compensator senses the downstream pressure and adjust the displacement to maintain the set pressure. The control would be used on systems where the flow requirements are variable but the pressure requirements are unchanging. Optional ControlsRemote Pressure Control, Load Sensing Control, Horsepower Limiting ControlConstructionCast iron body designed to deliver years of reliable performance. When service is needed, the pump can be disassembled and brought back into service.RotationClockwise or counter clockwiseSealsBuna N or VitonPortsSAE O-ring thread rear ports, SAE O-ring threaded side port, or (in HPV-20 and higher) SAE 4 bolt flange side port.ShaftStraight key or male splineOperating Pressures· Intermittent -- 4000 psi· Continuous -- 3500 psi · Minimum -- 200 psi Operating Speeds· Maximum -- 1800-3000 rpm· Rated -- 1750 rpm · Minimum -- 500 rpm |

Vane Pumps - General Specifications:Recommended FluidPetroleum base and most phosphate ester fluids, water glycols and emulsions with water content not exceeding 40%. For other fluids, consult factory.Operating SpecificationsFluid Temperatures (pump inlet)· Petroleum............Recommended maximum, 130°F · Water-base.........Recommended maximum, 120°F · Synthetic.............Recommended maximum, 130°F Aniline Point for Buna N Elastomers(Viton is not affected by Aniline Point...........................190°/230°F ... specified for petroleum base fluids only Viscosity· Start-up.............Maximum, 1000 SUS· At operating temperature, consult sales · Nominal.............ISO Grade 46 or 32 Operating TemperatureFluid temperatures up to 160°F will not appreciably affect pump performance. However, from a safety standpoint, temperatures above 130°F are not recommended. Specified operating viscosities must be followed for optimum life and performance. For continuous operating temperatures above 140°F, consult the fluid manufacturer for correct fluid at elevated temperatures.FiltrationISO 16/13Suction:..........Petroleum Fluids ... 100 mesh screen ........Water Base Fluids ... 60 mesh screen ........Phosphate Esters ... 60 mesh screen Return:...........ISO 18/15 (25 micron) to 1000 psi ........ISO 16/13 (10 micron) to 2000 psi These recommendations are for maximum service life. Consult with your fluid and filter manufacturer for concurrence. Drive CouplingJaw-type with flexible web recommended. Tire type flexing elements and chain type not recommended. Belt, chain and gear drives, consult factory.Drive Shaft AlignmentPump and motor shaft alignment must be within .003" TIR for maximum bearing life.Relief ValvesA relief valve is not required or necessary for pump outlet pressures less than 1500 psi. For pressures greater than 1500 psi, it is recommended that a direct-operated, differential piston relief valve be used to relieve pressure spikes and/or surges.Use a Continental Relief Valve P10L-RD08-600-G-S. Pressure Compensated ControlContinental Hydraulics' variable volume, positive displacement pressure-compensated vane pumps are highly efficient and reliable sources of hydraulic power. As the rotor turns clockwise, the volume between two adjacent vanes (segments) increases at the suction porting. When these segments enter the pressure port area the volume is reduced and forces the fluid through the pressure port. Maximum output occurs when the cam is in the extreme eccentric position. When system requirements are less than maximum pump output, the system pressure forces the moving cam ring up (against the spring), reducing eccentricity ... resulting in less flow.From 0 to full displacement, constant pressure is maintained by the spring. When system volume demand falls to zero, the system pressure drives the ring to a concentric position. This changes the pump displacement to zero while the system pressure is maintained. Options and AccessoriesContinental Pumps may be tandem mounted to achieve multiple pump operation from a single power source for separate or auxiliary circuits. Pump options include handwheel pressure and volume controls; dual volume, dual pressure control combinations and a variety of mounting arrangements. |
