The PVQ10-A2R-SE1S-20-C21-12 belongs to the PVQ Piston Pumps series and is produced by Vickers for closed-loop hydraulic automation. It is an inline piston unit with variable volume control, so flow adjusts automatically to demand. A geometric displacement of 10.5 cc per revolution delivers moderate circuit flow while limiting pump size. The rated speed of 1800 rpm matches common electric motors used on industrial machinery. At a compensator setting of 210 bar the swashplate shifts to hold pressure, preventing overloads in actuators. When running at that pressure the input power reaches 7.4 kW, identifying the motor horsepower required for continuous operation. The inlet side tolerates up to 2 bar positive pressure, helping reduce cavitation during high cycle duty. Drive torque is transmitted through a 0.75-inch diameter shaft with a 1.75-inch straight key, and right-hand clockwise rotation aligns with standard SAE drive patterns. Installation uses the SAE J744 82-2 mounting flange which allows direct coupling to an A-frame motor pad.
The pump weighs 7.2 kg, light enough for single-person handling during maintenance. Hydraulic lines connect to 1.0625-inch SAE O-ring ports located at the rear, which simplifies manifold block layout and keeps hoses inside the envelope. An on-stroke response time of 0.040 s produces rapid flow increase, aiding servo valves that require quick pressure recovery. Case drain pressure must stay below 0.35 bar to avoid loading internal bearings, and the shaft seal is Buna-N to retain oil against that low backpressure. The inlet can tolerate a vacuum of 5 in Hg, so reservoirs may be placed slightly below pump level if the suction line is short. Together, these features define the operating envelope and support efficient flow regulation in compact hydraulic systems.
