Product Descriptio

The Komatsu PC150-5 and PC180-5 excavator hydraulic main pump assembly features an original dual-piston pump structure, precisely compatible with the hydraulic systems of older 5th generation 15/18-ton models. It boasts a one-piece cast pump housing, and the valve block, servo regulator, and flange mounting plate are all replicated from the original, requiring no modification and allowing for direct replacement.

1. Employing load-sensing variable control logic, it dynamically adjusts the output flow according to the excavation load. This provides ample power for heavy-duty excavation and smooth, gentle leveling movements under light loads, effectively improving common issues such as stalling, lack of power when warmed up, and sluggishness during complex movements.

2. The internal plunger, distributor plate, and return plate are made of high-hardness wear-resistant alloy, and the oil seals are made of aging-resistant fluororubber. This design prevents internal and external leakage during prolonged high-temperature operation, making it suitable for various engineering conditions such as earthwork excavation, site leveling, and crushing.

3. The integrated main control valve block is molded in one piece, reducing the number of external oil pipe joints and minimizing oil leakage problems at the source. It precisely matches the original engine power curve, providing load-sensitive energy-saving control. Compared to ordinary replacement pumps, it has lower fuel consumption and is more cost-effective in the long run.
