The PVH057R01AA10A250000001001AB010A pump is produced by Vickers within the PVH and PVE Open-Circuit Piston Pumps series and supplies variable flow for hydraulic automation systems. Its displacement of 57.4 cm³ per revolution fixes the volume delivered each shaft turn, while right-hand clockwise rotation matches prime movers that turn in the same direction. A 1.25 in shaft diameter defines the coupling size and transmits torque to the rotating group. A single fluorocarbon shaft seal contains case pressure and resists hot petroleum fluids. The 4-Bolt C mounting flange aligns the housing to standard SAE C faces for straightforward installation. A 2-1/2 in inlet port admits fluid with low restriction, and a 1-3/8 in outlet port carries pressurized flow to actuators. The pressure-compensator controller trims the swashplate angle so outlet pressure stays at a preset level when demand varies.
The pump employs a Q250 valve plate that times port openings to minimize cross-port leakage and improve volumetric efficiency. A bottom drain port with a 0.750-16 SAE O-ring thread vents case oil while helping purge trapped air. There is no auxiliary mount, leaving no pad for piggyback gear pumps and keeping the unit compact. Torque sensing is not provided, so load feedback other than pressure cannot influence displacement. The absence of an unload valve means standby flow must be diverted by external circuitry. Control special features are not included, simplifying service and reducing adjustment points. No diagnostic ports are present, so pressure checks require external fittings.
