Abstract
A self-priming centrifugal pump is disclosed in which major structural components of the pump housing are constructed from molded reinforced corrosion resistant plastic material. Internal parts of the pump housing which are subject to corrosion and abrasion from pumped liquids are formed using corrosion resistant metal and are permanently affixed to certain of the plastic pump housing components. The plastic components are reinforced against distortion resulting from pressure forces acting on them. Parts of the pump housing are detachably connected by clamping structure to permit replacement or repair of the pump impeller without requiring formation of load bearing threads in the plastic pump housing parts.
