Detailed Product Description

1.Our CA4VSO piston pump can interchange with A4VSO piston pump.

2. Variable displacement axial piston pump of awash plate design for hydraulics closed circuit transmission;

3. Flow is proportional to drive speed and displacement and is infinitely variable;

Output flow increases with swivel angle from 0 to its max value;

4. Swiveling the pump over centre smoothly changes the direction of flow;

A highly adaptable range of control and regulating devices is available;

5. The pump is equipped with two pressure relief valves on the high pressure ports to protect the hydraulics transmission (pump and motor from over load);

6. These valves also function as boost inlet valves;

7. An integral auxiliary pump serves as boost and pilot oil pump;

8. The integral pressure cut off is standards.
