The PVB5FLSY20CM11 pump belongs to the Piston Pumps series and is produced by Vickers. It is an axial piston unit intended for hydraulic automation where consistent volume delivery is needed for actuators and valves. The design operates in an open circuit so reservoir fluid returns directly to the inlet, simplifying cooling loops. At its rated speed of 1800 rpm, the pump displacement of 10.55 cm³ per revolution yields a calculated flow of 18.9 L/min (5.0 gpm), enabling moderate power transmission in mobile or industrial machinery.
For pressure limitation, the unit uses a CM pressure compensator that automatically throttles swash-plate angle as system pressure approaches the 100 bar (1500 psi) setting. Displacement is available on one side of center, giving the pump a single directional stroke that reduces complexity in mounting fixtures. When viewed from the shaft end, the rotating group turns anticlockwise, which determines motor coupling orientation during installation.
