PSV-PNSF-25ERD-56

The PSV-PNSF-25ERD-56 pump is produced by Bosch Rexroth as part of the PSV Variable Vane Pumps series. Designed for hydraulic automation, it supplies variable flow while maintaining compact integration in power units. The unit is a variable volume vane pump, which adjusts its displacement to match circuit demand and reduce energy loss. A rated operating pressure of 1000 psi defines the maximum system load it can sustain without damage. At 1800 rpm it delivers 20.2 gallons per minute, a volume suited to medium-capacity actuators and manifolds. Right-hand rotation coordinates with standard electric motor drives, and a subplate mounted interface permits quick replacement or service without disturbing piping.

Flow regulation is achieved through a two-stage compensator that reacts to pressure changes in consecutive steps for stable delivery. The control configuration is a pressure compensator, so outlet flow decreases automatically as system pressure approaches the set point. Because there is no separate volume control, displacement changes rely solely on this internal pressure feedback rather than manual adjustment. Viton sealing elements are used to contain hydraulic oil and tolerate elevated temperatures common in industrial duty. Together these features allow the PSV-PNSF-25ERD-56 to maintain consistent pressure, prevent overshoot, and simplify circuit design in automated machinery.
