PSV80/SV20 6974033 62

The PSV80/SV20 6974033 62 variable vane pump belongs to the PSV Variable Vane Pumps series and is produced by Bosch Rexroth. It supplies regulated oil flow for hydraulic automation systems in which demand changes during the duty cycle. The unit is pilot operated so remote pressure feedback can shift the ring and vary delivery without stopping the drive. A displacement of 8.0 in³ per revolution determines the basic volume moved each shaft turn, and the pump delivers 62 gpm when run at 100 psi and 1,800 rpm. Operating speed can be reduced to 750 rpm for lower flow or raised to 1,800 rpm for full output. Installation flexibility is achieved because the housing can be mounted in any position, while an ISO 3019-1 flange aligns the shaft with common motors. Rotation is right-hand only, so the prime mover must drive the shaft clockwise.

Maximum system pressure is 1,500 psi, which defines the highest load the pump can sustain without overstressing internal components. The inlet circuit must remain between 11.6 psia and 24.5 psia to avoid cavitation and keep seals within design limits; maintaining this window supports consistent vane tracking and long bearing life. At 72 lb, the pump’s weight should be factored into bracket sizing and lifting plans during assembly or service. By observing these pressure and weight parameters, the unit integrates safely into presses, machine tools, and other automated hydraulic stations that need steady, adjustable flow from a compact variable vane source.
