PVM141ER14JS02AAB2311000 FA0A

The PVM141ER14JS02AAB2311000 FA0A is an axial piston pump manufactured by Vickers within the PVM Code A Piston Pumps series. It supplies hydraulics with a geometric displacement of 141.0 cm³ per revolution (8.60 in³/rev), so every rotation moves a fixed fluid volume for predictable flow control. The maximum operating speed is limited to 1800 rpm when used with valve plate E, which protects internal parts from excessive surface velocity. Clockwise right-hand rotation is specified, allowing direct coupling to prime movers that turn in the same direction. Power is transmitted through an SAE D 13-tooth spline input shaft, providing a durable connection to the drive motor. A four-bolt SAE J744-152-4 mounting flange secures the housing to the machine frame and maintains alignment under load. Low-pressure supply fluid enters through a 2.5 in SAE J518 suction port, while pressurized oil exits through a 1.25 in SAE J518 Code 62 discharge port sized to handle rated flow without excessive velocity. Both main ports are located on the side of the case, simplifying rigid pipe runs in horizontal installations.

System limits are set by a continuous pressure capability of 230 bar (3300 psi), allowing the pump to run steadily in high-duty circuits, and a peak pressure tolerance of 280 bar (4000 psi) for short duration load spikes. A pressure compensator is factory set to 230 bar so the unit automatically destrokes when outlet pressure reaches that value, preventing overloading. The integrated pressure and flow compensator type B combines this pressure control with a flow control loop, permitting automatic adjustment of displacement to match demand. Flow reduction begins at the 11 bar differential established by the flow compensator setting, enhancing efficiency during partial load conditions. A 9/16-18 UNF-2A load-sense port provides the external signal needed for remote pressure feedback, enabling coordinated control with directional valves. An SAE C-C 17-tooth spline auxiliary mounting pad is available to drive a secondary pump or accessory from the same prime mover. A single shaft seal confines hydraulic fluid within the housing and prevents contamination ingress, supporting long service life.
