Product Description

This is the HPV091 main hydraulic pump of the Hitachi EX120-3 excavator, which is the core power unit of the entire machine. It perfectly fits the Hitachi EX120-3 model, and is also compatible with the EX120-2 model. The installation base and oil port layout are exactly the same as the original vehicle, without the need to modify the pipelines. It can be directly replaced with the entire machine, making it a high-quality assembly part for major repairs and pump replacements of 12-ton excavators.

The pump body is made of high-strength cast steel and is formed as a single piece. It has a stable structure and is equipped with a power regulating valve body. The flow output is stable and controllable. The overall compound action is smooth and coordinated, with abundant digging force. The internal pistons and flow distribution discs have undergone high-precision quenching and grinding, ensuring excellent sealing performance. They can withstand high pressure and resist wear. Long-term earthwork operations are less likely to encounter internal leakage, insufficient pressure, or slow movements.
