PV3-022-18

The PV3-022-18 piston pump is part of the Piston Pumps series from Vickers and is intended for hydraulic automation systems. It operates on a positive-displacement principle, so every shaft revolution moves a fixed volume independent of outlet pressure changes. The displacement of 0.22 in³ per revolution (3.605 mL/rev) suits compact circuits where precise flow metering is required. Because the displacement is variable, the user can trim delivery to match load demand and limit energy waste. A recommended running speed of 10000 rpm maintains efficient swashplate motion and keeps internal loads within design limits.

At the 10000 rpm operating point the pump produces a theoretical flow of 9.52 gpm (36.05 L/min), supplying predictable oil volume for actuator sizing and heat balance calculations. A system pressure rating of 3000 psi (207 bar) allows the unit to work in medium-pressure machinery without exceeding case stresses. The maximum overspeed capability of 12500 rpm provides a safety margin during start-up or brief speed excursions. A dry weight of 4.6 lb (2.1 kg) simplifies handling and permits mounting on structures that have limited load capacity. These characteristics show how the PV3-022-18 can deliver adjustable flow while remaining compact and durable.
