The PVQ32-B2R-SE1S-21-C14-12 piston pump is produced by Vickers as part of the PVQ Piston Pumps series for closed-loop hydraulic automation. Its displacement of 32.9 cc per revolution determines the theoretical flow rate generated at a given drive speed. A pressure-compensator control automatically trims the swashplate angle, and the compensator setting of 138 bar (2000 psi) defines the point at which this adjustment occurs to prevent excessive outlet pressure. The unit is designed for continuous operation up to 140 bar, establishing the maximum working pressure allowed in the circuit. A rated speed of 1800 rpm provides full volumetric output without overspeeding the rotating group, while the maximum input power of 15.6 kW (21 hp) indicates the motor capacity required at peak load. Right-hand clockwise rotation matches engines or electric motors that turn in a standard clockwise direction.
A straight keyed SAE B modified input shaft links the pump to the prime mover, and the 2.31 in shaft length supplies sufficient engagement for torque transfer. The SAE B two-bolt mounting flange, coupled with an SAE J744 101-2 interface, allows direct installation on common pump pads. Fluid enters and exits through 1.625 in ports located at the rear, sealed with SAE O-ring fittings to minimize leakage during pressure cycles. A maximum case pressure of 0.35 bar (5 psig) protects the Buna-N shaft seals from extrusion and extends service life. Buna-N sealing material also ensures compatibility with standard petroleum-based hydraulic oils. The pump is supplied without a thru-drive, so it cannot be used to tandem mount additional hydraulic units on the same shaft.
