Displacement:46 cc/rev

Application:Applied in Aerial work platform and other Construction machinery

  • Variable axial piston pump of swashplate 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 swashplate is adjusted from zero to its maximum value.
  • Flow direction changes smoothly when the swashplate 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 integrated charge pump can provide system replenishing and cooling fluid flow.
  • High reliability, long working lifetime
  • Compact structure, high power density.
