The essential components of a centrifugal pump are the fast-rotating impeller and the casing. Water flows into the centre “eye” of the impeller, where centrifugal force pushes the water outwards, to the casing. The kinetic energy of the water is partly converted to useful pressure that forces the water into the delivery pipe. Water leaving the central eye of the impeller creates a suction, which draws water from the source into the pump. An impeller and the matching section of the casing is called a “stage”.
