ABSTRACT:
Longer shaft seal life in centrifugal pumps is realized by returning liquid from the pressure side of the pump to the seal area via a passage formed in a rib of the housing wall, and without porting the impeller, so that pump efficiency is kept high and its self-priming ability is retained.
