Product Descriptio

This is a Komatsu PC120-6 excavator-specific HPV95 integrated variable displacement piston hydraulic pump assembly. The main pump and pilot pump are integrated into one unit. The flange mounting plate, port layout, and solenoid valve plug are completely compliant with original factory standards, allowing for a non-destructive replacement of the original pump body without modification.

1. Equipped with a load-sensing constant power regulation system, it dynamically matches the engine output power, effectively improving engine stalling and speed drops during heavy-duty excavation, reducing hydraulic overflow losses, and balancing strong digging force with fuel economy.

2. The internal plungers, cylinder block, and distributor plate are made with high-hardness alloy heat treatment technology, resisting wear from hydraulic oil impurities, suitable for long-term high-intensity construction site operations such as earthmoving, stone crushing, and municipal renovation.

3. The pump body integrates the main regulator, power solenoid valve, and pilot/auxiliary pump. All pumps undergo full performance testing on a bench for pressure, flow, and combined actions before leaving the factory; lifting, traveling, and swing operations are synchronously responsive and smooth without jamming.
