Abstract
A mechanical seal assembly associated with a rotatable shaft means and comprising a pair of seal rings, one stationary and one rotatable with the shaft means, the seal rings having generally radially disposed engaging faces. A bellows means connected to the stationary seal ring resiliently urges it toward the rotatable ring. Resilient means locating the position of the rotatable seal ring resiliently counters the resilient force on said stationary ring by the bellows means. The entire seal assembly is on a sleeve which can be assembled with a shaft or removed therefrom as a unit.
