  • Centrifugal Pumps Selection Guide | Engineering360

    Centrifugal pumps operate using kinetic energy to move fluid, utilizing an impeller and a circular pump casing. A vacuum is created in the pump which draws fluid to the impeller by suction. The impeller produces liquid velocity and the casing forces the liquid to discharge from the pump, converting velocity to pressure.
