PVH57QICLF2S10C25V31027

The PVH57QICLF2S10C25V31027 piston pump belongs to the PVH and PVE Open-Circuit Piston Pumps series and is produced by Vickers. It supplies variable flow to hydraulic actuators in automated machinery. The pump carries design number 10, which aligns the internal components with the current parts catalog for interchangeability. A maximum displacement of 57.4 cm³ per revolution lets the unit deliver up to 98 L/min at 1800 rpm, giving sufficient oil volume for medium-power drives. The pressure limit reaches 250 bar, allowing the circuit to operate heavy cylinders without overstressing the housing. Pressure is regulated with a type C compensator so the outlet is trimmed automatically when system demand is met. Control design number 31 synchronizes the compensator response with other load-sensing elements, and the left-hand (CCW) rotation matches installations driven from engines or motors that turn counterclockwise.

For stable performance the factory setting fixes the compensator at 25 MPa, so the machine can be started without additional calibration. A load-sensing differential of 20 bar allows the controller to reduce swash-plate angle promptly when downstream pressure rises, improving energy efficiency during partial load. The pump mounts on an SAE C four-bolt flange defined by J744-127-4, and the main pressure and return lines connect through matching SAE four-bolt flanges to maintain standardized pipe geometry. A single one-way shaft seal prevents external leakage while accommodating internal case pressure. Quiet industrial trim reduces noise emissions on automated production lines, and a composite 2/4-bolt mounting feature coded 027 lets the housing interface with both rigid and flexible brackets, simplifying retrofits.
