Product Descriptio

This hydraulic main pump is specifically designed for the Komatsu PC300-6 excavator and is the core hydraulic power assembly of the entire machine. It strictly replicates the original factory structure, dimensions, flow, and pressure parameters. The flange mounting holes, oil pipe interfaces, and regulator components are completely identical to the original parts, allowing for non-destructive direct replacement. It is suitable for various PC300-6 engineering equipment overhaul and replacement needs.

The internal plunger, cylinder block, and distributor plate are made of high-wear-resistant alloy material and processed with a high-precision mirror-polished finish, resulting in extremely low internal leakage during high-pressure operation. Pressure calibration ensures stable and powerful output during heavy-duty digging, breaking, and slewing operations, without pressure drop, vibration, or abnormal noise. It balances the explosive power of heavy-duty digging with fuel control logic, correcting common problems in older equipment such as power loss, slow speed, and lack of power, restoring the feel of a new machine.
