PSV-PSSF-25ERM-56

The PSV-PSSF-25ERM-56 pump belongs to the PSV Variable Vane Pumps series from Bosch Rexroth and supplies regulated hydraulic flow for automated machinery. It is subplate mounted, allowing quick removal without disturbing external piping, and provides 20.2 gallons per minute at 1,800 rpm to satisfy medium-capacity circuits. A maximum working pressure of 1,000 psi supports common industrial loads, while right-hand rotation dictates drive motor orientation during installation. The unit employs a variable volume vane mechanism that adjusts displacement on demand to reduce energy use when the full rated flow is not required.

Screw-type volume control lets technicians set the displacement with basic tools and keeps the adjustment secure under vibration. A standard pressure compensator shifts the control element once outlet pressure reaches its preset point, diverting excess flow internally and stabilizing the circuit without an external relief valve. Viton seals resist hydraulic oil and elevated temperatures, extending service life in demanding environments. These features work together so the variable volume vane pump can deliver reliable flow modulation throughout repetitive press or material-handling cycles.
