In drinking water treatment, what is the main function of the impeller in a centrifugal pump?

The main function of the impeller in a centrifugal pump is to create flow. The impeller is a rotating component designed to transfer energy to the fluid, increasing its velocity as it moves through the pump. When the impeller spins, it generates centrifugal force that pushes the water outward, causing it to flow through the pump and into the piping system. This mechanism is essential for transporting water throughout the treatment facility or distribution system, ensuring that the water reaches various treatment stages or consumers effectively.

The design and operation of the impeller are crucial to the efficiency of the pump. A well-designed impeller can optimize flow rates and pressure delivery, which are vital for maintaining the overall performance of the drinking water treatment process.
