Komatsu Excavator Main Pump | HPV95, HPV132, HPV95+95 | PC200-7, PC300-7, PC400-7

Komatsu Excavator HPV Series Hydraulic Main Pump Assembly (HPV95 / HPV132)

Product Overview: This series of HPV axial piston variable displacement pumps is the core hydraulic power component specifically engineered for the full range of Komatsu excavators. Covering models from the compact PC60-7 to the heavy-duty PC400-7, we provide high-power-density single pumps (e.g., HPV132) and perfectly synchronized tandem double pump assemblies (e.g., HPV95+95). Renowned for their extreme pressure resistance and precise flow distribution, these pumps ensure your excavator maintains efficient and smooth power output during complex multi-function operations.

Key Technical Advantages:

• Superior Load-Sensing Control: Fully compatible with Komatsu’s original OLSS (Open Center Load Sensing System). Models like the HPV95 offer highly sensitive displacement response, instantaneously modulating output based on real-time loads on the bucket and boom to significantly reduce fuel consumption.

• Mining-Grade Durability: Optimized for large-tonnage machines such as the PC300-7 and PC400. Reinforced internal piston groups and port plates are designed to withstand sustained high-pressure shocks of 35 MPa, extending the Mean Time Between Overhauls (MTBO).

• 100% OEM Compatibility: Manufactured strictly to Komatsu OEM standards. Mounting flanges, shaft splines, and servo valve interfaces provide a seamless “drop-in” match for PC200-6/7 and PC220-7, ensuring rapid field installation.

• Low Noise & High Volumetric Efficiency: An acoustically optimized housing design drastically reduces hydraulic vibration noise during high-pressure operations. Precision-ground components ensure peak volumetric efficiency even under full-load conditions.
