The PVM074ER09GS02AAA28000001A0A pump belongs to the PVM Code A Piston Pumps series manufactured by Vickers for hydraulic automation circuits that require variable displacement pressure control. It employs a pressure compensator control so delivery is trimmed when system pressure reaches the 280 bar compensator setting. The geometric displacement is 73.7 cm³ per revolution, which allows 127 l/min flow at the maximum speed of 1800 r/min. Fluid enters through a 2.0 in SAE J518 inlet port and exits through a 1.0 in matching outlet, making line routing straightforward. A SAE C four-bolt mounting flange secures the case to the prime mover, and the dry weight of 45 kg keeps handling within standard lifting limits.
The input shaft tolerates up to 450 N·m torque while its 0.0078 N·m·s² rotating inertia minimizes load changes on the drive motor. Continuous operation is supported at 315 bar, and brief excursions to 350 bar peak pressure are acceptable during transient events. Dynamic response is defined by a 95 ms on-stroke rise time that brings the pump to full displacement and a 30 ms off-stroke time that returns it to standby flow, enabling rapid adjustment to actuator demand. These pressure and response capabilities let system designers achieve stable, high-performance motion control across the pump’s full displacement range.
