Product Description

This is the Hitachi ZX120-6 HPK055AT hydraulic main pump. The main component part number is 9227923. It integrates the main pump and the pilot pump into a single structure. It is the core power assembly of the 12-ton construction machinery. It precisely fits the Hitachi ZX120-6 model and is also compatible with models such as ZX110-6 and ZX130-5A. The installation flange and oil port positions are exactly the same as the original vehicle, so there is no need to modify the pipelines. The entire machine can be directly installed and replaced, making it a high-quality assembly component for major repairs of construction machinery or replacement of old pumps.

1. The pump body is precision cast from high-strength cast iron. The casing is thick and sturdy, resistant to impact and unlikely to crack.

2. It is equipped with the original power regulating valve body, with uniform flow distribution. The vehicle's lifting, rotation, and moving actions are smooth and coordinated, providing sufficient power, and effectively controlling fuel consumption.

3. The internal pistons and flow distribution discs have been quenched and finely ground. The sealing performance is stable, resistant to high pressure, and anti-wear. Long-term operations in earthwork and stonework do not easily cause internal leakage, pressure loss, or slow movements.
