Product Description

This K3V280DTH dual main pump is the core hydraulic power assembly for Hitachi EX2500-6, EX3600-6, EX5500, and EX8000 large-scale mining excavators. With an ultra-large displacement design, it provides abundant output flow, stable system pressure, and perfectly matches high-power engines. It offers sufficient power for mining operations in mines and heavy-load loading conditions, ensuring no problems such as stuck vehicles or reduced rotational speed.

1. The dual pumps adopt constant power cross-control, with balanced flow distribution. The lifting, rotation, and movement of multiple compound actions are smooth and fluent, significantly improving the efficiency of heavy-load mining operations.

2. The cylinder body, piston, and flow distributor plate are made of high-strength alloy steel and precisely matched and ground. They are resistant to high pressure and wear caused by impurities, with minimal internal leakage over a long period, effectively improving issues such as insufficient pressure, slow movements, and excessive oil temperature.

3. The installation flange, spline shaft, and oil ports are fully in accordance with the original factory standards. There is no need to modify the pipelines, and it can be directly installed in position, making it a reliable hydraulic assembly for major mine excavator overhauls and replacements.
