A self-priming lateral channel centrifugal pump having a pair of ribs formed in the suction chamber to enhance the self-priming features of the pump. The fluid traverses a substantial portion of the suction chamber before porting to the impeller, and the ribs are located just in advance of the impeller port. One of the ribs extends radially inwardly of the suction chamber and the other radially outwardly from the inner region of the chamber. The ribs are circumferentially spaced and both extend the entire axial width of the suction chamber and about half the radial depth of the chamber.
