PVE35QR122C21V1721

The PVE35QR122C21V1721 piston pump is manufactured by Vickers within the Piston Pumps series and provides regulated hydraulic power for automated machinery. It displaces 4.5 in³ per revolution, so a fixed shaft turn produces a predictable oil volume for accurate actuator control. When driven at 1800 rpm it supplies a rated flow of 35 GPM, covering medium-size circuits without supplementary boosters. Right-hand clockwise rotation lets the pump couple directly to standard prime movers found in industrial skids. A pressure-compensator control trims swash-plate angle to match load demand, while an internal limiter keeps outlet pressure at 250 bar to protect valves and piping from overload.

Energy efficiency and service life are improved by the integrated load-sensing control, which cuts displacement when downstream flow demand drops. Reliable operation requires hydraulic fluid cleanliness of ISO 19/15 or cleaner, limiting particulate wear on bearings and control edges. The casing uses an SAE J518 four-bolt flange, and the side-port flanged configuration eases rigid line connections inside compact manifolds. These ports remain aligned under pressure spikes, preserving seal integrity and reducing maintenance time. A quiet option is incorporated to lower airborne noise, making the pump suitable for installations where acoustic levels must stay within occupational limits.
