Serial Advantage

  • Swash plate design axial piston variable displacement pump for closed-loop hydrostatic transmission.

  • As the swash plate passes through the center, the direction of hydraulic oil flow changes smoothly.

  • Two pressure relief valves are installed on the high pressure side to prevent overloading.

  • Built-in make-up pump acts as make-up pump and control pump.

  • The maximum make-up pressure is limited by the built-in low-pressure relief valve.

  • New slewing components and bearings for improved transmission efficiency and higher input speed.

  • Optimized shell design, shock absorption and noise reduction.

  • Electrical proportional displacement control to meet the requirements of multi-industry applications.

  • A variety of oil outlet connection methods to optimize the pipeline connection.

  • Optional flushometer for direct mounting on the pump body.
