PVH74QP25VS21RCPN343524

The PVH74QP25VS21RCPN343524 is a piston pump supplied by Vickers within the PVH and PVE Open-Circuit Piston Pumps series. It supplies hydraulic actuators in automation systems by converting mechanical input into fluid flow. A displacement of 73.7 cm³ per revolution establishes the nominal volume moved each shaft turn and defines the base flow rate available to the circuit. The pump can operate up to 1800 rpm, so users can scale output by adjusting drive speed within that limit. A maximum input torque of 450 N·m indicates the mechanical load the drive motor must furnish during peak duty cycles. The SAE C 4-bolt mounting flange simplifies direct coupling to standardized power units and keeps alignment consistent. Right-hand clockwise rotation aligns with common engine drives and avoids cross-porting issues when retrofitting existing machines.

System protection and control features are supported by additional characteristics. A maximum pressure rating of 140 bar enables the pump to supply medium-pressure circuits without exceeding housing stresses. The 20 bar load-sensing differential allows external compensators to trim flow so that only the pressure required by actuators is generated, improving efficiency. SAE 4-bolt flange ports provide robust pipe connections that withstand vibration and prevent leakage. A single one-way shaft seal limits external leakage while permitting the internal shaft sleeve to be lubricated by the working fluid. The SAE C 2- and 4-bolt thru-drive mount lets the unit pass mechanical power to a secondary pump for tandem arrangements. Maintaining an oil cleanliness level of ISO 16/14/12 or cleaner reduces wear in the swash-plate assembly and prolongs service life.
