Abstract
The present disclosure relates to a fluid pump having a pump housing and an inlet wall portion positioned adjacent the pump housing. The inlet wall portion has an extending portion which extends generally parallel to an inner surface of the pump housing. A motor is housed within the pump housing. An impeller is included which is responsive to the motor. An impeller retainer is disposed adjacent the impeller and includes a radiused corner portion. An O-ring is positioned at the radiused corner portion. The O-ring exerts a force non-perpendicular to the inner surface of the pump housing to form a seal against the inner surface of the pump housing and the extending portion of the inlet wall portion.
