The PSV-PSAF-20DRM-66 pump belongs to the PSV Variable Vane Pumps series from Bosch Rexroth and provides adjustable hydraulic flow for automated machinery. A pressure compensator governs displacement to keep circuit pressure constant, while the unit withstands up to 2000 psi for medium-pressure tasks. At 1800 rpm it delivers 15.2 GPM, supporting consistent actuator speed under typical motor drive conditions. An eleven-vane set minimizes flow ripple and noise, and the variable volume vane design allows displacement changes without interrupting operation. Right-hand rotation matches common clockwise prime movers, aligning the shaft with standard power-unit layouts.
A flange mount with side SAE ports enables direct coupling to motors and compact pipe routing. The inlet connection is an SAE 24 straight thread (1 7/8-12) sized for the required flow, while the outlet uses an SAE 16 straight thread (15/16-12) to suit pressure lines; identical SAE straight threads on both ports simplify hose selection. Viton seals tolerate common hydraulic fluids at elevated temperatures to extend service intervals. A screw volume control lets technicians fine-tune displacement manually when system demand shifts.
