Open the catalog to page 2HPV SERIES AXIAL PISTON PUMPS VARIABLE DISPLACEMENT, PRESSURE COMPENSATED PRESSURE COMPENSATED Delivers only the flow required by the system, while maintaining the set pressure. This will save horsepower and unnecessary wear on the system. Pressure compensation ranges from 200 to 3500 PSI continuous duty and up to 4000 PSI intermittently. ANSI SYMBOL SAE FLANGE MOUNTING Uses standard SAE industrial mounting for easy interchangeability. 5 DISPLACEMENTS .88, 1.26, 2.09, 2.62, and 3.78 cubic inches per revolution. SIMPLE CONSTRUCTION For a long and productive life. RUGGED CONSTRUCTION Cast...
Open the catalog to page 3HPV SERIES AXIAL PISTON PUMPS GENERAL SPECIFICATIONS Maximum Inlet Pressure Recommended Fluids The maximum inlet pressure is 50 PSI at all speeds. Fluids for use in the HPV series piston pumps should be petroleum based and designated by 6 fluid manufacturer for use in hydraulic systhe tems. These fluids should contain rust and oxidation inhibition, anti-wear, anti-foam, and deaerating agents. For other fluid types, please contact your Continental Application Engineer. Recommended Operating Viscosities For petroleum based fluids: • • • Optimum -- 140 sus (30 Cst.). Continuous Minimum -- 60...
Open the catalog to page 4HPV SERIES AXIAL PISTON PUMPS PRESSURE COMPENSATED CONTROL The 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 adjusts the...
Open the catalog to page 5HPV SERIES AXIAL PISTON PUMPS REMOTE PRESSURE CONTROL (Code 7) The remote pressure control works similar to the standard pressure compensated control, with some added features. This is a two stage compensator with two pressure adjustments: one for the lower pressure limit and one for the upper pressure limit. this line may be controlled by one or more relief valves. These should be direct acting and capable of pressures up to 3500 psi (241 bar). The setting of these relief valves will control the pressure setting of the pump. A vent line* is required to run back to the reservoir. When this...
Open the catalog to page 6HPV SERIES AXIAL PISTON PUMPS LOAD SENSING CONTROL (Code 19) The load sense control is designed to deliver a constant flow across an orifice and adjust the pressure to meet the system's demands. This type of control is often called flow compensating. This is accomplished by using a flow control valve between the pump outlet and the actuator. ments. There are two adjustments on this compensator. The adjustment on the back side will set the upper pressure limit. The adjustment on the front is used to set the pressure differential of the flow control valve. This setting comes preset to 250 psi...
Open the catalog to page 7HPV SERIES AXIAL PISTON PUMPS HORSEPOWER LIMITING CONTROL (Code 26) The horsepower limiting control is designed to be adjustable down to 35% of the maximum horsepower requirements of a normally pressure compensated pump. This control has three adjustments that can tailor the performance curve to the system requirements. A sense line* is required to be connected to the line between the pump and the actuator. A calibrated orifice is installed in the outlet of the pump so there is no need to add any additional components to achieve this type of control. This control would be used in systems...
