The PVB10LSY41CM12 pump is manufactured by Vickers and belongs to the PVB Piston Pumps series, where it serves as a variable-delivery source for hydraulic automation circuits. A displacement of 21.1 cm³ per revolution defines the volume moved each shaft turn, while a flow of 37.5 L/min at 1800 r/min supports actuators that need moderate throughput. The unit tolerates a maximum drive speed of 3600 r/min so it can be coupled to fast electric motors, and its anticlockwise rotation suits powertrains built around left-hand drive direction. Threaded inlet and outlet ports sized 1.625-12 UN-2B (SAE) simplify attachment to common pipe fittings, and the housing places the inlet at port B and the outlet at port A to guide line routing. A 22.22 mm shaft diameter mates with standard hubs, and the 6.4 mm square × 22.3 mm key secures torque transfer without slip.
A 3/4-16 UNF-2B case-drain port vents internal leakage so housing pressure stays low and bearing life is protected. The 101.60 mm locating diameter centers the body in engine bell housings or pump pads for accurate alignment. A minimum ambient temperature of −20 °C allows cold-weather startup, and a maximum of +70 °C prevents thermal distress in hot enclosures. The pump requires hydraulic fluid no thinner than 13 cSt to maintain film strength across the pistons. System pressure is limited by a compensator that can be set between 17 bar and 100 bar; this range lets designers balance load response with energy use. Noise output is 61 dB(A) when running at 1000 r/min and 210 bar, helping facilities meet occupational sound limits.
