characteristics

1. The capacity of the pump is in proportion to its rotating speed and displacement; the stepless adjustment of the displacement can be materialized by regulating the swivel angle of its swash plate.

2. With through-shaft structure, able to form combination pump.

3. Position constraint return mechanism.

4. Spherical flow distribution, the piston is inclined around the shaft.

5. Equipped with swivel angle indicator of swash plate.

6. Stepless variable displacement.

7. Excellent suction performance.

8. Rated working pressure of 35MPa.

9. Fast control response.

10. Low noise.

11. Long lifespan.

12. Excellent power/weight ratio.

13. Modular design.

14. The drive shaft is able to bear the axial and radial load.

15. Optional installation position.

16. It can operate with HF fluid to lower the operating parameter.

17.Completely interchangeable with original
