Fixed Displacement Motor

Max displacement:27.4-180 cc/rev

Application for high pressure open and closed circuit.

  • Swashplate type piston motor, integrated with mechanical brake, relief valve, charge valve and anti-reaction valve;
  • Compact structure design with the motor’s rotating group, integral mechanical brake element and the attached valve options are neatly packaged together.
  • Special design of the mounting flange, can be directly connected with the reducer.
  • Based on the mature technology, weight is less, the structure is more compact and the output power is improved significantly.
  • Applied in the rotation condition of excavators and drilling rigs.
