Product Descriptio

This hydraulic main pump is custom-designed for the Komatsu PC350-6 excavator and is the core hydraulic power assembly of the entire machine. It completely replicates the original factory installation dimensions, flow and pressure parameters, and power adjustment structure. The flange mounting holes, oil line interfaces, and regulator components are completely interchangeable with the original parts, requiring no modifications to piping or supports. It can be directly replaced without damage, making it suitable for equipment overhauls and old pump replacements.

1. It adopts a thickened one-piece cast steel pump body, with a one-piece molding process that resists pressure and impact, preventing deformation and oil leakage during long-term high-pressure operation. It is equipped with a complete load-sensing regulator and control solenoid valve, precisely matching the PC350-6's original power control system. The power matching logic completely solves common problems such as pump stalling, unbalanced operation speed, and speed drop under heavy loads. The matte anti-rust paint surface resists corrosion from construction site mud, dust, and oil, making it resistant to rust during long-term outdoor operation.

2. The internal plunger, cylinder block, and distributor plate are made of high wear-resistant alloy steel and are processed by high-precision mirror grinding. Combined with high and low temperature resistant sealing kits, the internal leakage under high pressure conditions is extremely low. The combined action of digging, crushing, rotating, and walking is smooth and powerful, without problems such as vibration, abnormal noise, or weak pressure relief.
