A centrifugal pump is a mechanical device that moves fluids by converting rotational energy from a motor into hydrodynamic energy using a rotating impeller. As the impeller spins, it creates a flow of fluid outward from the center, increasing the fluid's pressure and velocity. Centrifugal pumps are widely used in various applications, such as water supply, industrial processes, and automotive systems, due to their efficiency and ability to handle large volumes of fluid. They are essential components in many modern systems requiring fluid movement.
