Product Description

This main hydraulic pump, designed for the new generation of medium-sized excavators E320GC and E323GC, is the core component of the entire machine's hydraulic power system. It directly determines the excavation force of the equipment, the sensitivity of compound actions, and the fuel consumption performance. The E320GC and E323GC, as the main models of the GC series, are widely used in various engineering scenarios such as earthwork excavation, infrastructure construction, mining stripping, and site loading. The entire machine has strict standards for the pressure control, load response, and durability life of the hydraulic pump in terms of new-generation models. 

The pump body shell is formed by a single piece of high-strength alloy cast iron through casting. It undergoes a complete aging stress-relieving process. The shell has strong rigidity and can withstand high-frequency and high-pressure impacts, resisting external losses caused by dust on the construction site, temperature differences, and vibrations. It is less likely to experience shell deformation or cracking. The internal core friction pairs such as the cylinder body, piston assembly, valve plate, and return plate are made of high-hardness wear-resistant materials. They undergo multiple precise grinding processes and are strictly controlled in the component clearance to effectively suppress leakage in the pump body and ensure that the equipment maintains a high volumetric efficiency for long-term continuous operation.
