PVH74QPCRM1S10C16V1931091

The PVH74QPCRM1S10C16V1931091 piston pump is manufactured by Vickers within the PVH and PVE Open-Circuit Piston Pumps series. Designed to supply variable flow in hydraulic automation circuits, it is built on pump design number 10, indicating the specific internal component set adopted for this model. Control design number 31 identifies the version of the control cartridge that interfaces with external regulators. The pump moves a maximum of 73.7 cm³ per revolution, so displacement establishes the volume transferred each shaft turn. When driven at the rated maximum speed of 1800 rpm, it produces up to 125 L/min of flow for actuators or manifolds. A standardized SAE C 4-bolt mounting flange simplifies coupling to electric or diesel prime movers, and right-hand clockwise rotation matches drives that turn in that direction.

System pressure management relies on a type C pressure compensator that throttles swash plate angle to hold pressure. The unit tolerates a maximum working pressure of 250 bar, while a factory pressure setting of 160 bar is pre-adjusted so startups occur without field calibration. A load-sense differential of 20 bar maintains a small margin above load demand, permitting proportional valves to shift reliably. Fluid connections are provided through SAE 4-bolt main ports with metric threads, enabling secure high-pressure piping. A single shaft seal blocks oil from escaping at the drive end and keeps contaminants out of the case. These characteristics support consistent performance in open-circuit systems that require quick response to varying flow and pressure demands.
