Abstract
An coolant pump for an internal-combustion engine including a housing, a cover sealingly coupled to the housing, an impeller assembly located between the housing and the cover, the impeller assembly defining a longitudinal axis and being rotatable about the longitudinal axis; and a flange positioned between the housing and the cover adjacent the impeller assembly such that the flange and the cover define a first cavity, the flange and the housing define a second cavity, and the flange includes an opening fluidly connecting the first and second cavities, the flange being contoured to at least partially surround the impeller assembly. Preferably, the pump also includes a nozzle contoured to direct a coolant from the first cavity toward the second cavity and onto the impeller assembly, and wherein the nozzle has an intake side communicating with the first cavity and a discharge side communicating with the second cavity.
