PVE47-QIL-2-22-C25-21

The PVE47-QIL-2-22-C25-21 piston pump is produced by Vickers within the Piston Pumps series for closed-loop hydraulic automation systems. It converts mechanical energy to hydraulic flow for actuators and proportional valves. The pump delivers a displacement of 6.00 in³ per revolution, establishing the volume moved every shaft turn and directly influencing circuit speed. At 1800 rpm the rated flow reaches 47 GPM, supplying medium-capacity drives with consistent volume. A pressure setting of 250 bar (3625 psi) defines the maximum outlet pressure tolerated before compensation, protecting downstream components from overload. Fluid cleanliness must meet ISO 19/15 so that particulate contamination does not accelerate wear on the rotating group or control surfaces.

For installation and control, the unit uses a pressure compensator, which modulates swash-plate angle to maintain the set pressure once demand falls and thereby minimizes wasted horsepower and heat generation. A splined input shaft coded as option 2 transfers torque without key slippage, streamlining coupling to electric or diesel primemovers and permitting higher cyclic loads. The 4-bolt flange port style secures inlet and outlet lines with uniform clamping force, maintaining seal integrity under high pulsation and simplifying maintenance in rigid manifolds. Design number 21 identifies this version’s internal revisions and ensures compatibility with the current parts list across the series.
