• 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.
