In water treatment, what does a centrifugal pump primarily do?

A centrifugal pump primarily moves water through mechanical force. This type of pump operates by utilizing a rotating impeller that transfers energy to the fluid, causing it to move. The rotation of the impeller creates a centrifugal force that pushes the water outward from the center of the pump, effectively lifting it and allowing it to flow through the discharge pipe.

This mechanical action is fundamental to the operation of a centrifugal pump, distinguishing it from other types of pumps that may rely on different mechanisms, such as creating a vacuum or electronic systems. While increasing the pressure of water is a result of the pump's operation, it is not the primary function described for centrifugal pumps; their main role is to facilitate the movement of water using mechanical means.
