HYDRAULIC PUMP WHEEL

The hydraulic pump wheel in the Komatsu engine is connected to the operation of the hydraulic pump and transmits power from the combustion engine to the hydraulic pump. Using a belt system, the hydraulic wheel drives the hydraulic pump. This application is found in medium excavators, e.g. in the SAA6D107 model. On the other hand, in large machines in the SAA12V140 model, more advanced systems are used where the hydraulic wheel cooperates with gears. In smaller construction machines in the SAA4D95 model, light hydraulic wheels drive a hydraulic pump operating with a moderate load.
