| Description |
Control devices: HD, HD3, HW, DG, DA1, DA2, EP3, EP4, EZ1, EZ2, etc.
Nominal pressure 4350 psi (300 bar); Peak pressure 5100 psi (350 bar)
Control device: MD, HD, HW, DG, DA, EP, EZ, etc.
The A10VG variable axial piston pump of swash plate design for hydrostatic closed circuit transmission
- 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
