The PVQ20-B2R-SE1F-21-CM7-12-S44 pump belongs to the PVQ Piston Pumps series and is manufactured by Vickers for hydraulic automation circuits that need steady flow and compact packaging. The unit displaces 21.1 cc per revolution (1.290 in³/rev), and this volume combines with a rated speed of 1800 r/min to set its nominal output. It can work against system pressures up to 210 bar (3000 psi), drawing 14.9 kW (20 hp) at that limit. Right-hand clockwise rotation matches common prime movers, while an SAE J744 101-2 (SAE B) mounting flange aligns with standardized motor faces. Power is transmitted through a straight keyed SAE B input shaft that is 2.31 in long, allowing direct coupling without adapters.
An internal low-pressure compensator is factory set to 70 bar (1000 psi) so the outlet pressure can be limited when full system capacity is unnecessary. Inlet conditions permit up to 2 bar (30 psig) positive pressure, and suction can reach 5 in Hg vacuum, while case pressure must stay below 0.35 bar (5 psig) to protect internal components. Rear SAE O-ring ports measuring 1.625 in handle both inlet and outlet flow paths, simplifying manifold connections. A fluorocarbon shaft seal resists hydraulic fluid and temperature cycling, and the design is supplied without a thru-drive, preventing tandem pump mounting. The assembly weighs 14 kg (31 lb), supporting installation on mobile or stationary frames without heavy reinforcement.
