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.
