Product Description

This K3V280 main hydraulic pump is the power core assembly of Hitachi ZX670LC-3, ZX870H-3 and EX1200-3 large-sized excavators. The engine has a powerful displacement and can perform multiple operations in coordination without causing engine stalling. It has excellent sealing performance, is resistant to wear and has low internal leakage, making it suitable for high-intensity continuous construction in mines.

1. The constant power regulator has a sensitive response, and the flow distribution of the dual pumps is balanced. The compound actions of lifting the boom, rotating, and moving are smooth and continuous, fully exerting the operational efficiency of large-scale mining equipment.

2. The cylinder body, piston, and flow distributor plate are all made of high-strength wear-resistant steel. They have undergone high-precision matching grinding and are resistant to high pressure and high temperature. The internal leakage is extremely low during long-term continuous operation, effectively solving the problems of slow movements, insufficient power of the entire machine, and excessively high oil temperature.

3. The installation flange and oil ports are exactly the same as those of the original factory assembly. There is no need to modify the pipelines. They can be directly installed in position. It is a high-quality main pump component for major excavators during major repairs and complete machine renovations.
