Swash plate axial piston variable pumps for closed circuit hydrostatic transmission

1. The flow rate is proportional to the driving speed and displacement and can be infinitely variable.

2. The flow rate increases with the swashplate swing angle from zero to its maximum value; 3.

3. The swashplate swing through the center can smoothly change the direction of liquid flow.

4. Easy to match with a variety of control and regulation system of a variety of variable mode; 5.

5. The pump is equipped with two relief valves on the high-pressure oil side to protect the hydrostatic transmission (pump and motor) from overload.

6. The high pressure relief valve also functions as a charge valve.

7. Built-in auxiliary pumps are used as charge and control pumps.

8. Maximum charge pressure is limited by a built-in charge relief valve.

9. Full series with built-in pressure shut-off valve.
