The PVM045ER05CS01AAA2800000 CA0A axial piston unit is part of the PVM Code A Piston Pumps series from Vickers and supplies variable-displacement flow for hydraulic automation. A geometric displacement of 45.1 cm³ per revolution sets the theoretical volume transferred each shaft turn, while a dry weight of 24 kg affects support structure selection during installation. The rotating group inertia of 36.2 kg-cm² defines the acceleration load the drive motor must overcome. Operating range spans from 0 r/min to a ceiling of 1800 r/min with the E valve plate, enabling speed-controlled circuits that idle or ramp as needed. A nominal pressure rating of 315 bar covers continuous duty, and a peak capability of 350 bar allows brief overloads without damage. Shaft demand reaches 221 Nm at 280 bar, so the prime mover must be sized for that torque.
Flow capacity rises with speed when the pump is held at 280 bar: 42 l/min at 1000 r/min suits low-duty actuators, 49 l/min at 1200 r/min covers moderate work cycles, 65 l/min at 1500 r/min meets higher throughput needs, and 76 l/min at 1800 r/min supports full-output systems. The drive must also supply up to 41 kW at 1800 r/min and 280 bar, which defines the motor and power-train rating. Dynamic control is aided by a 140 ms on-stroke response time and a 40 ms off-stroke response time for Code A control, allowing the pump to adjust delivery quickly when system demand rises or falls.
