The PVM045ER06CS2A315000001AB pump belongs to the PVM Code B Piston Pumps series from Vickers and serves as a variable-delivery source for hydraulic automation circuits. Its geometric displacement of 45.1 cm³ per revolution defines the volume of fluid moved each shaft turn, providing predictable flow calculations. Clockwise input rotation aligns the pump with right-hand prime movers found in most mobile and industrial drives. A SAE J744-25-1 straight keyed shaft (B-B) permits direct coupling to standard electric motors without special adapters. The SAE B two-bolt mounting flange positions the housing on common pump pads for quick installation. Side-mounted main ports help shorten piping runs inside compact power units, while SAE J518 flange connections offer high-pressure sealing. A continuous rated pressure of 315 bar establishes the allowable working limit, and the pressure compensator is preset to 315 bar so flow is automatically reduced when that value is reached.
The unit employs a pressure-compensator control that modulates swashplate angle to maintain system pressure without external valving. Peak pressure capability of 350 bar accommodates temporary transients during load shocks. When driven at 1800 r/min under 315 bar, the pump delivers a maximum flow of 76 l/min, matching the requirements of medium-size cylinders and motors. A maximum input power demand of 41 kW defines the motor rating needed to avoid overload, and the allowable top speed of 1800 r/min matches standard four-pole electric motors. Maximum torque at 315 bar reaches 221 Nm, information used to size couplings and keys. The rated inlet pressure of 1.0 bar absolute indicates the minimum suction head necessary to prevent cavitation. A dry weight of 24 kg influences mounting support and facilitates single-person handling during service.
