The PVQ20 B2R SE3S 21 C21 12 pump belongs to the PVQ Piston Pumps series from Vickers and supplies regulated hydraulic flow in automation circuits. Its geometric displacement of 21.1 cm³ per revolution defines the volume delivered each shaft turn, and a rated speed of 1800 rpm lets the unit pair with standard electric motors. The pump handles a maximum pressure of 210 bar to support medium-pressure actuators, requiring 14.9 kW of input power at that limit so drive sizing can be matched. Right-hand clockwise rotation aligns with common power-take-off arrangements, and an SAE J744 101-2 mounting flange enables direct attachment to a B-frame motor face. Fluid enters through a 1.625-inch SAE O-ring inlet and exits through an identical 1.625-inch outlet, both configured as rear ports to keep external plumbing parallel with the housing.
The pressure compensator is preset to 210 bar, allowing circuit relief devices to match the pump’s upper operating limit, while internal case pressure is restricted to 0.35 bar to protect shaft seals. Power transmits through a splined SAE B 13-tooth 16/32 DP input shaft that mates with common couplings, and Control Design 12 governs the compensator response for steady flow regulation. Nitrile seals provide compatibility with petroleum-based fluids, and the assembled unit weighs 14 kg for easy handling during installation or service. No thru-drive section is present, so the pump operates as a standalone prime mover without provisions for stacking additional hydraulic devices.
