HA4VSG variable displacement-axial -piston pump description:
| Swashplate axial piston pump | Flow is proportional to the drivek speed and to the displancement |
| Adjust the angle of awashplate to reslize the stepless variable | Nominal pressure resch to 35Mpa |
| Good suction charateristic | Long service life,high-precision besrings |
| Have the structural design of compact, lightweight, low noise characteristics | Hydrostatic balance slipper,improve the life of pump |
| The sensitivity of control system | With swashplate angle indicator |
