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.

Applications:

1. Mining Machinery: Closed-circuit design with 400 bar pressure ensures stable power for hydraulic excavators in heavy loads, while swashplate adjustment adapts to complex terrain.
2. Construction machinery travel drives: The closed-loop design and bi-directional displacement control of A4VG enable efficient energy conversion and smooth stepless speed regulation for construction machinery, adapting to dynamic loads on rugged terrains..
3. Marine Propulsion: Smooth neutral swashplate reversal enables bidirectional flow control for marine propulsion, eliminating power transition shocks.
4. Hydraulic systems for concrete pump trucks: Infinitely adjustable swashplate angle optimizes flow for pumping operations, while 450bar peak pressure enhances concrete delivery efficiency.
5. Hydrostatic drives in agricultural machinery: Closed-circuit hydrostatic drive with load-sensing system reduces fuel consumption in tractors while enabling precise control.

Competitive Advantage:

1. Closed-circuit piston pump with 400 bar pressure ensures stable power for mining machinery under heavy loads, integrated relief valves prevent system overload‌.

2. Swashplate axial piston pump enables infinite flow adjustment and smooth reversal for marine propulsion, achieving precise bidirectional flow control‌.

3. High-pressure piston pump with dual relief valves handles pressure spikes in tunnel boring machines, integrated boost pump ensures reliability in complex geology‌.

4. Closed-circuit energy recovery in axial piston pump reduces energy consumption for port cranes, swashplate angle control enhances operational efficiency‌.

5. Electrically controlled piston pump integrates with PLC for precise pitch system response in wind turbines, multi-position installation adapts to spatial constraints‌.
