Product Description

Hitachi EX120-5 hydraulic main pump assembly, HPV091 variable piston pump, perfectly compatible with Hitachi EX100-5 and EX120-5 excavators. The pump body is made of high-strength cast steel and is formed as a single piece. The cylinder body, piston, and flow distributor plate are all made of high-maintenance alloy materials, effectively reducing internal leakage and preventing pressure drop. The dual electromagnetic valve electronic control structure ensures rapid flow regulation response, smooth overall compound action, and abundant digging force. 

1. Hydraulic structure: Variable piston design ensures stable pressure output and continuous stable power supply, meeting the requirements of various working conditions such as earthwork and crushing.
2. Electrical control system: Dual proportional solenoid valves precisely control the displacement, allowing smooth switching between fast and slow movements, significantly improving the coordination of the entire machine and eliminating any stalling.
3. Durability: The core friction pairs are made using quenching and wear-resistant processes, which prevent overheating and leakage during long-term continuous operation, significantly extending the service life.
4. Installation advantages: The flange interface is exactly the same as that of the original vehicle, eliminating the need for modifying the pipelines. The installation and disassembly are convenient, enabling quick completion of equipment repair.
