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
