Variable Displacement Piston pump A10VO 53 series for Tractor & Mini Excavator, China Variable Displacement Piston pump A10VO 53 series for Tractor & Mini Excavator Manufacturers, Suppliers, Factory - Wenzhou Prance Hydraulic Equipment Co., Ltd

Feature:

1.Variable pump with axial piston rotary group in swashplate design for hydrostatic drives in open circuit.

2. Flow is proportional to drive speed and displacement.

3.The flow can be infinitely varied by adjusting the swashplate angle.

4.Stable bearing for long service life.

5. High permissible drive speed.

6. Favorable power-to-weight ratio – compact dimensions.

7 Low noise.

8.Excellent suction characteristics.

9.Electro-hydraulic pressure control.

10. Power control.

11.Electro-proportional swivel angle control.

12.Short control response times.
