PVH57QICRF1S10C2531

The PVH57QICRF1S10C2531 piston pump belongs to the PVH and PVE Open-Circuit Piston Pumps series from Vickers and supplies pressurized oil for automated hydraulic machinery. It displaces 57.4 cm³ per revolution, so each shaft turn moves a precise fluid volume to the circuit. At its rated speed of 1800 rpm, the unit provides 98 L/min of flow, which supports medium-duty cylinders and motors without auxiliary boosters. An SAE C 4-bolt mounting flange (J744-127-4) lets the housing bolt directly to common electric or diesel prime movers. Right-hand clockwise rotation matches the drive direction of most industrial power units. Vickers assigns design number 10 to identify the mechanical configuration used in this build. The quiet industrial design application indicates internal porting and timing selected to lower airborne noise in plant installations.

Pressure regulation is handled by a “C” style pressure compensator that trims displacement to keep line pressure within limits during variable demand. The compensator is factory set to 250 bar, so the pump throttles once that pressure is reached. Continuous operation is permitted up to a maximum working pressure of 250 bar (3625 psi), protecting downstream valves and actuators from overload. Control design number 31 refers to the specific compensator hardware package installed for consistent response characteristics. SAE 4-bolt flange main ports provide rigid, leak-resistant pipe connections suitable for open-circuit layouts. A single, one-way shaft seal prevents external oil leakage while allowing internal pressure relief toward the case, reducing seal wear during long running periods.
