PVH057R01AA10B252000001001AB010A

The PVH057R01AA10B252000001001AB010A pump is part of the PVH and PVE Open-Circuit Piston Pumps series from Vickers and is intended to deliver regulated hydraulic flow in automated machinery. It offers a geometric displacement of 57.4 cm³ per revolution, so each turn of the drive shaft moves 3.50 in³ of fluid through the circuit. At its rated speed of 1800 rpm the unit supplies 98 L/min, providing 26 gpm to cylinders, motors, or manifolds that demand steady volume. A maximum operating pressure of 250 bar permits the pump to support systems that work up to 3625 psi without internal damage. Pressure-compensated load-sensing control (PCLS) adjusts the swashplate angle to maintain flow while limiting excess pressure rise. Right-hand clockwise rotation matches common diesel or electric prime movers. The input shaft measures 1.25 in in diameter, and a standard 4-bolt C mounting flange aligns the housing with SAE C power take-offs.

Fluid enters through a 2-1/2 in suction port sized to reduce inlet velocity and prevent cavitation, then exits the housing via a 1-3/8 in pressure outlet that connects directly to system piping. A bottom-facing .750-16 SAE O-ring drain port returns case leakage to tank, keeping bearing cavities relieved of excess pressure. Sealing is handled by a single fluorocarbon shaft seal that resists heat and petroleum-based fluids during continuous duty. Internally, a Q250 valve plate meters the cylinder block passages to maintain volumetric efficiency across the entire pressure range. The design does not include an auxiliary output shaft, so side loads are limited to the primary drive end. Diagnostic pressure ports are not provided, which means pressure checks must be taken from external test points. Together these features support predictable performance in mobile or stationary hydraulic automation where compact, open-circuit piston pumps are preferred.
