PSV-PSSF-20HRD-56

The PSV-PSSF-20HRD-56 pump is a variable volume vane unit in the PSV Variable Vane Pumps series from Bosch Rexroth, intended to supply adjustable flow to hydraulic automation systems. At 1800 rpm it delivers 15.2 GPM, giving mid-range capacity for machinery that needs consistent oil delivery. A pressure compensator control keeps outlet pressure near the set point by trimming displacement as demand changes. Eleven vanes travel around the cam ring each revolution to produce smooth flow with minimal pulsation. Right-hand rotation aligns with standard clockwise drive shafts to simplify coupling arrangements.

A 2000 PSI pressure rating allows this model to serve moderate-pressure clamping, forming, or servo functions without overstress. Viton seals tolerate higher temperatures and many synthetic fluids, extending service life in demanding environments. Subplate mounting permits fast swap-out without disturbing hard plumbing, reducing downtime during maintenance. Displacement is set by a screw volume control so operators can fine-tune flow directly at the pump. Together these characteristics support precise, reliable performance wherever compact, easily regulated hydraulic power is required.
