High-pressure Construction Machinery Piston Pump with 400 bar For Mining Equipment
Features:
1. Variable axial piston pump of swashplate design for hydrostatic drives in closed circuit.
2. The flow is proportional to the drive speed and displacement.
3. The flow can be infinitely varied by adjusting the swashplate angle.
4. Flow direction changes smoothly when the swashplate is moved through the neutral position.
5. A wide range of highly adaptable control devices with different control and regulating functions, for all important applications.
6. Two pressure-relief valves are provided on the high-pressure side to protect the hydrostatic transmission (pump and motor) from overload.
7. The high-pressure relief valves also function as boost valves.
8. The integrated boost pump acts as a feed pump and control pressure supply.
9. The maximum boost pressure is limited by a built-in low pressure relief valve.
10. As standard with integrated pressure cut-off.
