Product Description

This main hydraulic pump, designed for large-tonnage excavators such as DX480LCA, DX520LCA, and DX520LC, is the core component of the entire machine's hydraulic power system. It directly controls the digging force of the entire machine, the response speed of compound actions, and the overall operational efficiency. This series of models is mainly used in heavy-duty work conditions such as mining, rock removal, and large-scale earthwork loading. There are strict standards for the pump's pressure resistance, wear resistance, and load adaptability.

The pump body shell is made of high-strength cast steel and is formed by a single casting process. It undergoes stress relief treatment to withstand frequent high-pressure impacts in mining environments, effectively preventing the shell from deforming or cracking. The internal key friction pairs, including the cylinder, piston assembly, flow distributor, and return disc, are made of high-hardness wear-resistant alloy materials. They undergo multiple precision grinding processes, with precise control of the part clearance, minimizing internal leakage losses and ensuring that the equipment can maintain a high volumetric efficiency for long-term continuous operation.
