This hydraulic main pump perfectly fits multiple Komatsu excavator models, including PC300-7, PC300-7-AA, PC300HD-7L, PC300LC-7, PC300LC-7-BA, PC300LC-7L, PC340LC-7K, PC340NLC-7K, PC350-7, PC350-7-AA, PC350LC-7, PC350LC-7-BA and PC360-7. All mounting interfaces and installation dimensions fully match OEM standards for seamless replacement.
Manufactured strictly in accordance with original OEM specifications and dimensional standards. The hydraulic pump features the same installation ports and assembly structure as the original part, requiring no modification during installation. It can directly replace old or damaged pumps to quickly restore excavator working performance and reduce equipment downtime.


Adopts high-strength alloy cast iron and precision-machined internal components. Key parts such as piston and cylinder block undergo professional heat treatment to enhance surface hardness, wear resistance and high-pressure resistance. The integral reinforced pump body effectively avoids deformation and oil leakage under long-term high-load and harsh working conditions.
Optimized internal flow channel design reduces hydraulic energy loss and pressure fluctuation. This main pump delivers stable output pressure and flow, ensuring smooth operation of boom, arm and bucket actions. It improves overall working efficiency and reduces fuel consumption, maintaining consistent performance during continuous heavy-duty excavation work.
We provide brand new and professionally remanufactured hydraulic pumps for selection. The new pump achieves 100% original performance, while the remanufactured pump is fully disassembled, cleaned, replaced with worn parts and strictly tested. Both versions meet OEM working standards, realizing high cost performance for different maintenance demands.
Every hydraulic main pump passes professional factory tests including pressure test, sealing test and load operation test. Strict quality inspection from raw materials to finished products ensures zero leakage, stable operation and long service life, fully adapting to mining, road construction and other harsh engineering scenarios.
Compared with expensive original factory parts, our Komatsu hydraulic main pump has the same reliable performance with a more competitive price. It effectively reduces equipment maintenance costs and later operating expenses, being the ideal replacement accessory for excavator maintenance companies and construction teams.
