OEM Parts for KOBELCO SK250-8 Main Pump | Partsdic®

The main pump for the KOBELCO SK250-8 is a high-performance hydraulic pump designed to deliver efficient and reliable power to the excavator's hydraulic system.

It is a variable displacement axial piston pump that operates under high-pressure conditions. The pump is specifically designed to meet the demands of heavy-duty excavator applications, ensuring optimal performance and productivity on the job site.

The main pump features a robust construction and is made from high-quality materials to ensure durability and longevity. It is engineered to withstand the rigors of demanding working environments, including extreme temperatures, heavy loads, and constant vibrations. The pump's design incorporates advanced technologies to minimize wear and maximize efficiency, resulting in extended service life and reduced maintenance requirements.

The main pump has a displacement of X cubic centimeters per revolution (cc/rev). This displacement value determines the amount of hydraulic fluid the pump can deliver with each revolution. A higher displacement value indicates a greater flow rate, which translates into increased power and faster operation of the excavator's hydraulic functions. The main pump for the KOBELCO SK250-8 is designed to deliver a substantial flow rate to meet the machine's requirements.

The pump operates at a maximum pressure of Y bar, where the pressure is measured in bars. This high-pressure capability ensures that the excavator can handle heavy loads and perform demanding tasks with ease. The pump's ability to maintain consistent pressure throughout its operation contributes to smooth and precise control of the excavator's movements and functions.

To ensure efficient and reliable operation, the main pump features advanced control mechanisms.

It is equipped with a pressure compensator that adjusts the flow rate based on the load requirements, optimizing energy consumption and minimizing heat generation. The pump also incorporates a torque limiter that protects against overload situations, preventing damage to the pump and other components.

The main pump is driven by the excavator's engine through a power take-off (PTO) system. It is designed to work seamlessly with the engine, providing a reliable power source for the hydraulic system. The pump's connection to the engine ensures synchronized operation and efficient power transfer.
