The PVQ10-A2R-SE1F-20-C21D-12 piston pump is part of the PVQ Piston Pumps series from Vickers and is used to deliver controlled hydraulic power in automated machinery. It displaces 10.5 cm³ for every revolution, and when driven at its rated speed of 1800 r/min it supplies 18.9 L/min of oil to actuators. A right-hand clockwise rotation sets the drive direction for standard SAE A couplings, while a pressure compensator trimmed to 210 bar limits system pressure to protect downstream components. The inlet port is a 1.0625-12 UN-2B SAE O-ring connection, supporting easy hose attachment, and the circuit may admit up to 2 bar of inlet pressure or withstand a vacuum of 0.2 bar during suction conditions. These features combine to keep flow steady and cavitation low in compact hydraulic control loops.


A 0.75 in keyed SAE A input shaft that is 1.75 in long transfers torque from the prime mover, and the housing mounts on an SAE J744 82-2 flange for direct engine or motor installation. A 9/16-18 UN-2B case drain port returns leakage oil to tank, while an adjustable maximum displacement stop lets technicians fine-tune pump output to match circuit demand. The unit reaches full stroke in 0.040 s, enabling responsive pressure and flow changes, and the case vent can endure 0.35 bar of internal pressure without oil bypass. Fluorocarbon seals resist heat and fluid additives found in industrial systems, and the complete assembly weighs 7.2 kg, easing handling during service or retrofit work.
