Product Description

This K3V280 hydraulic main pump is the core power unit of the Hitachi ZX650 excavator. It is specially designed for heavy-duty operations in large-scale mines. With a large displacement dual piston structure, it provides sufficient flow and stable output pressure. It is matched with a high-power engine, ensuring that during heavy-load excavation and loading operations, there is no vehicle congestion or speed drop. 

The electronic control regulator precisely controls the displacement, ensuring balanced flow distribution. The multiple compound actions of the boom lifting, rotation, and movement are smooth and coordinated. The operational efficiency has been significantly improved. The cylinder body, piston, and flow distributor are all made of high-strength alloy steel, which have undergone high-precision matching and grinding. They can withstand high pressure and high temperature, and have extremely low internal leakage during long-term continuous operation. This effectively resolves common faults such as insufficient movement force, slow lifting, and excessive oil temperature.
