Product Descriptio

This hydraulic pump is a dedicated main pump assembly for the Komatsu PC300-7 excavator. As the core of the machine's hydraulic power, it completely replicates the original factory assembly dimensions, pressure and flow parameters, and electronic control adjustment structure. The flange mounting holes, oil pipe interfaces, and solenoid valve components are fully compatible with the original parts, allowing for direct replacement without modification. It is a core component for equipment overhauls and old pump replacements.

1. The internal plunger, cylinder block, and distributor plate are made of high-hardness wear-resistant alloy and undergo high-precision mirror grinding, resulting in extremely low internal leakage under high-pressure conditions.

2. The output pressure is strictly calibrated according to original factory standards, providing smooth and powerful power output for digging, breaking, and slewing operations, without vibration, abnormal noise, or insufficient pressure relief.

3. It balances heavy-duty digging power with fuel-saving control, completely repairing problems such as power attenuation and slow operating speed in older equipment, restoring the operating feel of a new machine.
