The PVM074MR11GS02AAC2820000AA0A pump belongs to the PVM Code A Piston Pumps series and is manufactured by Vickers for closed-loop hydraulic automation circuits. This variable displacement unit delivers 73.7 cm³ per revolution and produces a maximum flow of 163 L/min when it runs at the rated 2400 r/min under a system pressure of 280 bar. Continuous operation is supported at a nominal pressure of 315 bar, while short-term peaks up to 350 bar are permitted. A pressure compensator is factory-set to 280 bar so the pump automatically trims displacement once that level is reached. Output power is transmitted through an SAE C 14-tooth spline defined by SAE J744-32-4, allowing direct coupling to industrial drive shafts. The assembly weighs 99 lb, making it suitable for mounting on medium-frame power units without additional structural reinforcement.
For power delivery, the pump absorbs up to 63 kW at 1800 r/min and can accept an input torque of 334 Nm when the circuit reaches 280 bar. It is capable of running at speeds down to 150 r/min for low-flow standby modes and up to 1900 r/min when inlet pressure is 0.8 bar, provided the displacement is adjusted accordingly. Oil viscosity must be kept between 16 cSt and 40 cSt to maintain bearing film integrity and response accuracy. Stroke transition dynamics are characterized by an on-stroke response time of 85 ms and an off-stroke response time of 30 ms, enabling rapid flow adjustment in servo-controlled systems. These operating limits define the pump’s integration envelope for applications that require stable displacement control across varying load demands.
