Product Description

This hydraulic main pump is the hydraulic assembly for Hitachi ZX470-3 excavator, and it is also compatible with ZX450-3 electronically fuel-injected models. The pump body integrates an independent fan-driven auxiliary pump, perfectly matching the original vehicle's hydraulic cooling circuit, effectively controlling the oil temperature and enabling the machine to adapt to long-term continuous heavy-duty operations in mines.

1. The dual variable piston structure ensures balanced power distribution of the two pumps, stable flow output, and effectively avoids vehicle stalling and speed drop during heavy-load excavation. It is equipped with the original electric control regulator, with sensitive action response, and the lifting, rotation, and traveling compound actions are coordinated and smooth.

2. The core friction pair is made of high-strength wear-resistant material, which has been precisely ground. Long-term use results in low internal leakage, effectively curing common problems such as slow operation, weak overall performance, and pressure drop under high temperatures.

3. The flange installation holes, oil ports, and pipelines are exactly the same as the original components. There is no need to modify the pipeline, and it can be directly aligned and installed. Maintenance and replacement are time-saving and efficient.
