The PVM045ER06CS2B315110001AB piston pump is produced by Vickers and belongs to the PVM Code B Piston Pumps series. This variable-displacement unit supplies hydraulic power to automated machinery. Its displacement is 45.1 cm³ per revolution, allowing stable volume delivery for medium-sized circuits. A clockwise right-hand input rotation matches common electric motor drives, and the SAE J744-25-1 straight-keyed input shaft provides positive torque transfer to the pump element. The pump attaches to power units through an SAE B two-bolt mounting flange so installation aligns with standard industrial bell housings. A maximum speed of 1,800 rpm sets the upper operating envelope, and at this speed the pump can deliver 76 L/min when the system is held at 315 bar. Under the same conditions it absorbs up to 41 kW of input power, so motor sizing must accommodate that load. The rated operating pressure is 315 bar, defining the continuous duty point for closed-loop or open-loop hydraulic systems.
For transient events the pump can withstand a peak pressure of 350 bar, while a maximum case pressure of 3.5 bar limits backpressure on the housing seals. System designers can rely on 221 Nm of output torque at 315 bar, and the shaft is approved for up to 215 Nm of input torque so couplings must respect this value. Fluid connections are made with SAE J518 flanges on the main ports to simplify rigid pipe installation. The inlet line must maintain at least 0.85 bar absolute to avoid cavitation during high-demand starts, and the on-stroke response time is 140 ms, enabling rapid flow adjustment when control signals change. A dry weight of 24 kg permits manual handling during maintenance and aligns with common bracket ratings.
