Abstract
A mechanical seal assembly for use with centrifugal pumps including at least one unitized elastomer assembly for urging the seal faces of a pair of seal rings into sealing engagement with each other. The unitized elastomer assembly serves as a seal ring mounting arrangement and includes a spaced pair of metallic rings which are chemically bonded to an annular elastomer body disposed therebetween and whose cross section between the rings is loaded in shear when the elastomer assembly is operatively arranged in the pump. A mechanical seal is established between at least one of said rings and the elastomer body for protecting the chemical bond therebetween against attack by corrosive pump product.
