The PVH74QPCRBM13S10C16V1731092 piston pump belongs to the PVH and PVE Open-Circuit Piston Pumps series manufactured by Vickers for hydraulic automation systems that require variable oil flow. Its displacement of 73.7 cm³ per revolution defines the volume delivered to cylinders and motors each shaft turn. A maximum operating pressure of 140 bar lets the unit handle medium-pressure circuits without overstressing components, while a top speed of 1800 rpm provides adequate flow in compact packages. Right-hand clockwise rotation aligns with common engine outputs to simplify direct coupling. A compensator pressure control keeps outlet pressure stable, and the 20 bar load-sensing differential decides when the compensator reacts so energy is conserved during partial loads. Pump design number 10 and control design number 31 mark internal revisions for replacement tracking and compatibility.
The mechanical drive is based on a 38.10 mm shaft diameter that transmits power from prime movers, seated against a 42.39 mm shoulder that positions the rotating group accurately. A 9.52 mm key width offers a secure torque path to couplings, and a single one-way shaft seal blocks external leakage while allowing case pressure to vent inward. The pump accepts up to 765 N·m of input torque on shaft code 13, enabling direct drive from high-power diesel engines. For multi-pump assemblies, the SAE-B thru-drive interface conforming to SAE J744-101-2/4 can pass 460 N·m to an additional pump, keeping overall package length short. These torque limits guide designers when selecting couplings, and the standardized thru-drive ensures alignment and vibration control in stacked pump arrangements.
