ABSTRACT:
A system for providing a labyrinth seal and a contact seal between a housing and a shaft is formed of a stator and a rotor connected to each other. The stator includes a flange biased toward the rotating shaft to prevent fluid from exiting the housing. The rotor rotates frictionlessly relative to the stator, creating a two-piece non-contact labyrinth seal to prevent contaminants from entering the housing. The rotor and stator may be held together by an annular protrusion located within a recess.
