A4VSO180DR Hydraulic Axial Piston Pump

The concept of HILEAD A4V series design applies oblique cylinder hole structure, spherical with flow, static pressure balanece, and shaft drive structural design. The hydraulic pump has a high rated working pressure, low noise, good self-priming ability, stable performance alternating load, can withstand the radial force, has multiple forms of variable, and long working life etc.

HILEAD A4V series hydraulic pump has a variety of variable form of matched control conditions for any hydraulic system applications.

Advantages:
1. Variable displacement swash plate axial piston pump
2. Flow is proportional to the drive speed and the displacement.
3. Adjust the angle of swashplate to realize the stepless variable
4. Rated working pressure reach to 350 bar
5. Good suction characteristic
6. Long service life, high-precision bearings
7. Have the structural design of compact, light weight, low noise characteristics
8. Hydrostatic balance slipper, improve the life of pump
9. The sensitivity of control system
10. With swashplate angle indicator
