Product Description

Suitable for Komatsu PC60-8 and PC70-8 hydraulic main pump assemblies, specially designed for small excavators of 6-ton and 7-ton class. The variable plunger pump adopts an integrated design in one unit. It integrates the main pump, pilot valve, power regulation solenoid valve, and control valve assembly into a single unit. This eliminates the cumbersome process of separate assembly and uses the original flange size. The original vehicle pump body can be directly replaced without any damage.

1.The core is equipped with high-maintenance-piston and alloy friction disc, which can withstand high temperatures and resist wear caused by oil impurities. It is suitable for the high-frequency operation conditions of small excavators.

2. Equipped with a built-in load-sensing power control system, it precisely matches the engine's output power, reducing overflow losses. Compared to ordinary aftermarket pumps, fuel consumption is reduced by 8% to 12%.

3. Precisely replicate the original factory oil circuit layout, installation flange dimensions, and electronic control circuit interface. It is compatible with the original vehicle engine and main control valve. Installation does not cause engine stalling or pressure loss.
