PSV-SNSF-25ERM-110/115-56

The PSV-SNSF-25ERM-110/115-56 variable vane pump is produced by Bosch Rexroth for the PSV Variable Vane Pumps series. It supplies variable oil flow to hydraulic automation circuits where pressure and flow must be managed precisely. The pump is subplate mounted to integrate directly onto standardized valve manifolds and reduce external piping. Design series 56 marks the current mechanical revision so spare parts match the latest internal geometry. A flow output of 20.2 GPM is reached at the reference speed of 1800 RPM, providing a fixed performance point for system sizing. A pressure rating of 1000 psi supports medium-pressure machines without overstressing the housing or bearings.

Solenoid two pressure control gives the pump the ability to shift between two preset operating pressures on command, supporting load cycles that alternate between low and high demand. Right-hand rotation defines the correct drive orientation so the inlet and outlet ports align with standard power units. Viton seals protect against fluid swelling and maintain leakage integrity at elevated oil temperatures. The absence of any volume control means the delivered flow varies only with shaft speed and the internal vane displacement, simplifying commissioning when external throttling devices handle flow regulation.
