Product Descriptio

This hydraulic main pump is a universal main pump assembly for Komatsu PC350-7 and PC360-7 excavators. As the core hydraulic power source for the entire machine, its flow and pressure parameters, electronic control adjustment structure, and oil- and high/low temperature resistant sealing components make it suitable for high-intensity and harsh working conditions such as mining, large-scale earthmoving, infrastructure demolition, and river dredging.

1. The internal plunger, cylinder block, and distributor plate are made of high-hardness wear-resistant alloy steel, precision-assembled after high-precision mirror grinding, and equipped with high-temperature and aging-resistant sealing kits, resulting in extremely low internal leakage under high-pressure conditions.

2. The flange fixing holes, oil line interfaces, solenoid valves, and power regulators are completely universal, requiring no modification to pipelines or supports, and can be directly replaced without damage.

3. The output pressure is strictly calibrated according to the original factory standards, ensuring smooth and powerful power output for synchronized excavation, breaking, swinging, and traveling movements, without vibration, abnormal noise, or weak pressure relief.
