PSV-PNSF-20HRS-56

The PSV-PNSF-20HRS-56 pump belongs to the PSV Variable Vane Pumps series and is manufactured by Bosch Rexroth. Designed for hydraulic automation circuits, this variable volume vane pump adjusts displacement to match load requirements, reducing wasted energy. Output is governed by a pressure compensator that trims flow once system pressure reaches its setting, preventing over-pressurization. The unit delivers 15.2 gallons per minute at 1800 rpm, supplying actuators with stable flow for medium-duty machinery. Right-hand rotation matches standard clockwise drive shafts in industrial power units, and a maximum working pressure of 2000 psi accommodates common factory hydraulic levels without overloading components.

Subplate mounting allows the pump to be fastened directly to a manifold, shortening pipe runs and easing maintenance in tightly packed cabinets. A new port plate coating reduces wear from fluid friction, extending service life under continuous duty. Viton seals withstand high-temperature petroleum-based fluids and many synthetic blends, minimizing leakage during long operating cycles. Design revision 56 identifies the current engineering release so spare parts and settings can be matched accurately. Because dedicated volume control is not included, displacement changes rely solely on the pressure compensator, simplifying external control hardware.
