The PVM045ER05CS01AAC2811000 AA0A pump belongs to the PVM Code A Piston Pumps series from Vickers and is intended to supply pressure for hydraulic automation circuits. It weighs 24 kg in dry condition, so mounting structures can be sized for moderate static loading. Each shaft rotation moves 2.75 in³, equal to 45.1 cm³, which determines reservoir sizing and cycle timing. Continuous operation is limited to a nominal system pressure of 315 bar, while a peak rating of 350 bar allows short-term overloads during rapid machine transitions.
The rotating group carries an inertia of 36.2 kg·cm², influencing motor acceleration requirements. When driven at 1800 r/min against 280 bar, the pump supplies 76 l/min, and the prime mover must provide 41 kW to sustain that flow. Maximum operating speed is 1800 r/min, yet the unit tolerates reduction down to 0 r/min for standstill conditions without damage. Shaft design must accommodate up to 221 Nm of torque at 280 bar, informing coupling choices and drive-train durability calculations.
