Abstract
A fluid pumping assembly in which an electrically operated motor is operatively connected to an impeller disposed in a volute housing. The volute housing is formed of two portions of a molded synthetic material which are joined together and which have rib means integrally formed on their inner faces for defining a priming chamber in the volute housing. A seal plate of a dielectric material extends within the volute housing and defines an opening for receiving drive means for the impeller.
