Abstract: A seal of a vertical pump with a front casing disposed on a main casing which has a motor disposed therein. A volute chamber is disposed inside the front casing to receive a centrifugal impeller. A suction inlet is disposed axially on the front casing opposite the motor. A water outlet is disposed thereon opposite the lateral side of the impeller to engage with a discharge pipe. The suction inlet and outlet are in communication with a volute chamber.
