Product Descriptio

This hydraulic main pump is specifically designed for the Komatsu PC300-5 excavator. As the core of the machine's hydraulic power, it replicates the original structural dimensions and pressure/flow parameters, perfectly adapting to older 30-ton Komatsu models. It is a high-quality replacement part for equipment overhauls and main pump replacements.

1. The entire pump body is made of one-piece cast steel. The flange mounting holes, pipe interfaces, and regulator mounting positions are completely interchangeable with original parts, requiring no modification and allowing for direct installation.

2. A complete set of electronic control regulators and power valve components is included, precisely matching the PC300-5's original power control system, resolving issues such as pump body mismatch, stalling, and uncoordinated operation in older equipment.

3. The internal plungers, cylinder block, and distributor plate are made of high-hardness, wear-resistant alloy material, precision-ground and assembled, resulting in minimal internal leakage under high-pressure conditions.
