PSV-PSAF-10HRM-66

The PSV-PSAF-10HRM-66 hydraulic pump is part of the PSV Variable Vane Pumps series produced by Bosch Rexroth for automated machine tool and industrial motion circuits. It functions as a variable volume vane pump, so the internal cartridge varies displacement to match required actuator flow and improve efficiency. A pressure compensator control adjusts the cam ring position to hold delivery pressure within set limits when demand drops, preventing energy waste. Rotation is right-hand, meaning the shaft must be driven clockwise when viewed from the drive end. Volume is trimmed with a screw adjustment, giving technicians a simple mechanical method to set maximum output during installation.

This pump is designed for continuous duty at 2000 psi, allowing it to serve medium-pressure servo valves, cylinders, and hydraulic motors without overstressing components. Flange mounting provides a rigid, self-centering interface that aligns the shaft with electric or combustion prime movers and speeds replacement in the field. Fluid lines attach to side ports machined with SAE threads, enabling direct use of common tube fittings while keeping the envelope narrow. All dynamic sealing surfaces use Viton material, which resists hot oil and many additive packages to maintain leakage control over long service intervals.
