Product Advantages

The swash plate is designed with an axial piston variable pump for closed circuit hydrostatic transmission.

When the swash plate passes the neutral position, the flow direction of the hydraulic oil will change smoothly.

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

The built-in charge pump acts as charge pump and control.

The maximum charge pressure is limited by the built-in low pressure relief valve.

Brand new slewing components and bearings, the transmission efficiency is improved, and the input speed increased.

One-piece design at the rear of the shell reduces leakage points.

Optimized shell design to reduce vibration and noise.

Electric proportional displacement control to meet the application requirements of multiple industries.

45° oil outlet design to optimize pipeline connection.

Optional flush valve, directly installed on the pump body.
