The PVQ20-B2R-SE1S-21-CM7-12 is a pump in the PVQ Piston Pumps series manufactured by Vickers for hydraulic automation duties. It provides 21.1 cc per revolution of displacement, supplying a steady flow to actuators that need medium volume delivery. A continuous rated pressure of 210 bar supports high-pressure circuits, while the 14.9 kW input power at maximum pressure aligns with common 20 hp electric motors. Right-hand (clockwise) rotation matches standard drive directions, and power is transferred through a straight keyed SAE B input shaft. The SAE J744 101-2 mounting flange centers the housing on SAE B equipment interfaces. Rear ports sealed with SAE O-rings shorten the installation envelope, and both inlet and outlet connections use 1.625-inch SAE O-ring fittings to ensure tight joints under pressure.
The CM7 low-pressure compensator controls standby pressure, and its 70 bar setting lowers energy use when full flow is not required. Case pressure must stay below 0.35 bar, so the drain line should return freely to tank to protect internal seals. Nitrile (Buna-N) sealing materials tolerate common petroleum-based fluids and maintain elasticity over standard temperature ranges. There is no thru-drive feature, which minimizes length when only one pump is needed in the circuit. An approximate weight of 14 kg (31 lb) allows a single technician to handle the unit during installation without lifting equipment.
