The PVQ10-A2R-SS1S-20-C21-12 pump belongs to the PVQ Piston Pumps series manufactured by Vickers for hydraulic automation circuits that need compact variable-displacement performance. Its geometric displacement is 10.5 cm³ per revolution, so each shaft turn moves that volume of hydraulic fluid. At the rated speed of 1800 rpm, the device provides an output flow of 18.9 L/min to supply actuators and valves. The maximum working pressure reaches 210 bar, and a pressure compensator is preset to 207 bar to stabilize system pressure near this limit. Driving the pump at maximum pressure and speed demands 7.4 kW of input power. Rotation is right-hand (clockwise) to align with standard prime movers, and torque is transferred through a straight keyed input shaft built to the SAE A modified profile; this shaft measures 0.75 in in diameter.
The mounting flange complies with SAE J744 82-2 (SAE A) to fit common motor bell housings without adapter plates. Side ports use SAE O-ring connections to minimize leakage paths, and both inlet and outlet openings are 1.3125 in to keep plumbing uniform. The inlet can accept pressures up to 2 bar, while internal case pressure must stay below 0.35 bar to protect bearings and seals. Buna-N sealing elements ensure compatibility with standard petroleum-based hydraulic oils in typical temperature ranges. The complete assembly weighs 7.2 kg, allowing a single technician to position the unit during installation or service.
