Product Description

This main hydraulic pump, designed to be compatible with ZX330, ZX330-3, ZX330-5, and ZX350 heavy-duty excavators, is the core component of the entire machine's hydraulic power system. It directly determines the digging impact force, smoothness of compound actions, and long-term operational stability of the entire machine.

The pump body shell is made by casting high-strength alloy cast iron as a single piece and undergoes a complete stress-relieving treatment. The shell is extremely rigid and can withstand frequent high-pressure impacts in mining scenarios, resist continuous vibrations, dust erosion, and temperature changes between day and night, effectively avoiding shell deformation, cracking, and other faults. The internal key friction pairs such as the cylinder body, piston assembly, flow distributor, and return disc are made of high-hardness wear-resistant alloy materials. They undergo multiple precise grinding processes, with strict control over the clearance between parts, minimizing internal volume leakage of the pump body and ensuring that the equipment can maintain a high volumetric efficiency for long-term continuous heavy-load operation.
