Abstract
A cartridge seal for sealing a space between a housing and a rotatable shaft includes a rotary sealing member having an inner surface defining a bore for receiving the shaft and a circular outer flange extending radially outwardly from and circumferentially about a central axis, the outer flange having a radial sealing surface. A static seal assembly is disposed about the rotary member and includes an annular casing coupleable with the housing and an annular static sealing member disposed within the casing and having a radial sealing surface engageable with the rotary member sealing surface to form a sealing interface. A biasing member axially biases at least a portion of the static sealing member toward the rotary member flange. An annular collar is disposed within the casing and axially retains the rotary member within the casing such that the seal assembly is mountable on a shaft as a single unit.
