PV3-022-25

The PV3-022-25 pump is produced by Vickers within the Piston Pumps series. Designed for hydraulic automation circuits, it regulates fluid output with a pressure-compensated control that maintains delivery once system pressure reaches 1500 psi. The inline configuration simplifies mounting in compact manifolds, and its axial piston, variable displacement mechanism adjusts the swept volume to match load demand. Each revolution displaces 0.22 in³ per revolution (3.605 mL), providing predictable flow for servo valves and actuators. During normal duty the unit operates at 10 000 rpm, a speed that yields a theoretical flow of 9.52 gpm (36.05 L/min) for machines requiring steady medium-pressure supply.

For intermittent peaks the PV3-022-25 tolerates speeds up to 12 500 rpm without compromising durability. It uses MIL-H-5606 hydraulic fluid, ensuring compatibility with standard aerospace service oils. The assembly weighs 4.6 lb (2.1 kg), so a single technician can handle installation in confined power units. Compact construction helps low-mass skids meet weight limits, and the housing alignment streamlines hose routing to cut assembly time. An overspeed margin of 2500 rpm above the recommended limit provides operational flexibility during start-up transients or rapid deceleration recovery. Combined with the lightweight build, this capability supports mobile platforms that need high-speed pressure supply.
