KYB original PSVL-54CG excavator hydraulic main pump for Kubota KX40 KX151 KX155

The hydraulic pump is a critical component in excavators, responsible for converting mechanical energy into hydraulic energy. It supplies high-pressure hydraulic oil to various actuators (such as hydraulic cylinders and motors), enabling smooth and efficient operation of the excavator. High-quality hydraulic pumps ensure durability, energy efficiency, and precise control, making them essential for construction, mining, and other heavy-duty applications.
