A pump shaft seal works on the rotating pump shaft where it passes through the non-rotating housing parts. Fluids enter your pump through the suction nozzle at the centre of a rotating impeller. As the impeller rotates, the vanes fill with fluid and are forced out of the pump housing through the discharge nozzle.
