For the drum drive in mobile concrete mixers A4VTG071, A4VGT090 series.

  • Variable axial piston pump of swash plate design for hydrostatic drives in closed circuit
  • The flow is proportional to the drive speed and displacement.
  • The flow increases as the angle of the swash plate is adjusted from zero to its maximum value.
  • Flow direction changes smoothly when the swash plate is moved through the neutral position.
  • Two pressure-relief valves are provided 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 pump and control pressure supply.
  • The maximum boost pressure is limited by a built-in boost pressure-relief valve.
  • Tapered shaft option for direct drive shaft yoke installation.
