What characteristic of centrifugal pumps makes them useful?

Centrifugal pumps are specifically designed to deliver fluids at various flow rates, particularly under conditions of low pressure. This characteristic stems from their operational mechanism, where the rotating impeller imparts velocity to the liquid, converting that velocity into flow. The ability to maintain high flow rates while overcoming relatively low pressure requirements makes centrifugal pumps highly efficient for a range of applications, especially in aquatic environments where continuous water movement is essential.

The high flow rate capability is vital in situations such as irrigation, water transfer, and managing aquatic pests, where a significant volume of liquid needs to be moved effectively. This feature underscores the preference for centrifugal pumps in scenarios demanding substantial fluid movement without the need for excessive pressure generation.
