  • Bellows seal with spring-loaded radial secondary seal
    Patent number: 6464231
    Abstract: A mechanical seal of the invention includes relatively rotatable seal rings and a secondary seal therefore. The secondary seal is a C-shaped spring loaded gasket having upper and lower gasket legs. The gasket is provided between two of the seal components, for example, between an axially movable seal ring and a bellows flange. The gasket has one leg thereof confined axially to transmit axial loads between the seal ring and the bellows flange. Also, the upper and lower gasket legs are biased axially apart by a spring to permit radial movement between the seal ring and the bellows flange and also accommodate different rates of thermal expansion between the seal ring and bellows flange.
