    Features:

     

    - Swashplate design Axial variable plunger pump for hydrostatic transmission in a closed circuit.
    - The flow is proportional to the drive speed and displacement.
    - As the swash plate angle increases from zero to its maximum value, the flow increases proportionally.
    - When the swash plate passes through the neutral position, the hydraulic oil flow direction changes smoothly.
    - Two pressure relief valves are fitted to the high pressure port to prevent overloading of the hydrostatic drive (pump and motor).
    - The high pressure relief valve can also be used as a charge check valve.
    - Built-in charge pump rushes current oil pump and controls variable use.

    - Optional with coupling flange for direct cardan shaft drive

    - Integrated boost pump for boost and pilot oil supply

    - Flow direction changes smoothly when the swashplate is moved through the neutral position

    - High-pressure relief valves with integrated boost function

    - Boost-pressure relief valve

    - Through drive for mounting of secondary pumps

    - Swashplate design
