A4VG rexroth series equivalent high pressure axial variable hydraulic piston pumps

Rexroth series A4VG28, 40, 56, 71, 90, 125, 180 hydraulic piston pump

All of HYLEMAN products are completely equivalent and interchangable with the original.

Features 

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

2. The flow is proportional to the drive speed and displacement.

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

4. 2 drain ports

5. Excellent suction performance

6. Low noise level

7. Long service life

8. Favorable power/weight ratio

9. Versatile controller range

11. Short control time

12. The through drive is suitable for adding Gear Pumps and axial piston pumps up to the same size, i.e., 100% through drive.

13. Suitable for operation with mineral oil and HF hydraulic fluids.

The A4VG axial piston variable pump in swash plate design for hydrostatic closed circuit transmissions
- Flow is proportional to drive speed and displacement and is infinitely variable
- Output flow increases with the swivel angle of the swash plate from 0 to its maximum value
- Flow direction changes smoothly when the swash plate is moved through the neutral position
- A wide range of highly adaptable control devices is available for different control and regulating functions
- The pump is equipped with two pressure-relief valves on the high pressure ports to protect the hydrostatic transmission (pump and motor) from overload
- The high-pressure relief valves also function as boost valves
- The integrated boost pump acts as a feed and control oil pump
- The maximum boost pressure is limited by a built-in boost pressure relief valve
- The integral pressure cut-off is standard
