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
HANJIU has been engaged in the hydraulic business since the beginning of the 20th century. It has a history of nearly 20 years and has always been upholding the principles of 'quality first', "credit first" and "zero complaint", and has become a new leader in the hydraulics industry. Hanjiu insists on good products, good service, and has been providing customers with better, more comprehensive hydraulic products, and constantly working hard.
At the beginning of the establishment of the factory, the industrial business started from the early OEM, and in the mid-term, the OEM and ODM as the main axis of industrial upgrading, recently began to develop its own brand 'HANJIU'.
Now our we have4 main business:
1, hydraulic motor and hydraulic steering unit
2, hydraulic piston pump
3, hydraulic gear pump
4, monoblock directional control valve
