PSV-SSAF-20HRM-66-110/115-66

The PSV-SSAF-20HRM-66-110/115-66 pump belongs to the PSV Variable Vane Pumps series and is produced by Bosch Rexroth. It is installed in hydraulic automation circuits to modulate flow and maintain set pressure levels. The unit uses solenoid two pressure control so a machine can switch between a high and a low pressure setting without manual valve adjustment. When driven at 1800 rpm it supplies 15.2 gallons per minute, meeting medium flow demands in machine tools or presses. The pump mounts on a flange with side SAE ports, simplifying replacement in standardized manifolds. Its inlet connection accepts an SAE 24 straight-thread fitting to match common suction hoses and reduce turbulence at the entry.

Its outlet port is sized for SAE 16 straight-thread hardware, allowing compact return lines while sustaining the rated discharge pressure of 2000 psi. The right-hand rotation matches most clockwise prime movers so shaft coupling remains direct. Internal components are sealed with Viton, supporting hydraulic oils that operate at elevated temperatures or contain synthetic additives. The variable volume vane mechanism automatically trims displacement to maintain commanded pressure, lowering heat generation during partial load. SAE straight-thread porting across all connections eases leak-free assembly with O-ring boss adapters. Together these characteristics enable precise pressure changeover, stable flow, and reliable service in closed-loop industrial hydraulics.
