Features

axial piston variable displacement pump Swashplate design provides consistent hydrostatic power in closed circuits.
proportional flow control Flow rate adjusts in proportion to your system’s drive speed and displacement, offering smooth and accurate regulation.
infinitely variable displacement adjustment Output flow increases from zero to maximum based on the swashplate angle, giving you full control over hydraulic performance.
seamless flow direction changes Effortlessly reverse hydraulic flow by adjusting the swashplate movement.
versatile control options A range of control modes let you customize your system’s response and efficiency.
integrated pressure relief system Each high-pressure side is equipped with dual relief valves to protect your hydrostatic transmission from overload.
dual-function relief valves These also serve as charge valves, ensuring steady system operation.
built-in charge pump Maintains charge pressure and supplies control oil for greater reliability.
pressure limiting function An internal charge relief valve regulates the maximum charge pressure to prevent excess strain.
standard pressure cut-off valve Integrated by default to enhance system protection.
