Features below:
1. Variable axial piston pump of swash plate design for hydrostatic closed circuit transmissions
2. Flow is proportional to drive speed and displacement and is infinitely variable
3. Output flow increases with the swivel angle of the swash plate from 0 to its maximum value
4. Flow direction changes smoothly when the swash plate is moved through the neutral position
5. A wide range of highly adaptable control devices is available for different control and regulating functions
6. The pump is equipped with two pressure-relief valves on the high pressure ports to protect the hydrostatic transmission
(pump and motor) from overload
7. The high-pressure relief valves also function as boost valves
8. The integrated boost pumps acts as a feed and control oil pump.
9. The maximum boost pressure is limited by a built-in boost pressure relief valve.
10. The integral pressure cut-off is standard.
Hydraulic fluid Before starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions. The variable pump A4VG is unsuitable for operation with HFA, HFB and HFC. If HFD or environmentally acceptable hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in RE 90221 and RE 90223 must be observed. When ordering, please indicate the used hydraulic fluid.
