PSV-PSCF-80GRM-65

The PSV-PSCF-80GRM-65 pump is manufactured by Bosch Rexroth within the PSV Variable Vane Pumps series. It supplies variable flow to hydraulic automation systems that require consistent pressure under varying loads. A standard pressure compensator limits outlet pressure so energy is saved when flow demand drops. Screw volume control provides a mechanical adjustment point for setting maximum displacement during commissioning. The pump rotates right hand, matching the clockwise direction of common electric motor drives. A modified vane tip profile lowers internal leakage and keeps volumetric efficiency stable across the operating speed range.

The housing is flange mounted, giving a rigid interface that maintains shaft alignment without additional support hardware. A four-bolt flange on the ports sustains the clamping force needed for reliable connections and speeds assembly in the field. Suction and discharge openings are placed on the side of the casing, allowing straight routing of hoses in tightly packed power units. Viton sealing elements withstand elevated oil temperatures and resist degradation from many hydraulic fluids, reducing maintenance frequency and leakage risk.
