A centrifugal water pump is used to transfer water from one location to another. The pump uses the centrifugal force generated by a rotating impeller to push water through the discharge pipe and out of the pump. The impeller rotates inside a casing, drawing water into the center and throwing it outwards, creating a flow of water through the pump. The function of a centrifugal water pump is to provide a constant and consistent flow of water to various applications, including irrigation, fire suppression, and industrial processes.
