Abstract
A seal cartridge adapted to be mounted upon a rotating shaft, including a rotor and a stator, the rotor and stator being arranged to create a labyrinth portion and a contact portion. The rotor includes a radially outwardly directed surface and the stator includes one or more flanges biased toward the rotor surface to create the contact portion. The rotor and stator create a labyrinth portion with an inwardly facing ridge positioned within an outwardly facing groove. The stator may include a shoulder for positioning the seal cartridge with respect to a housing, or instead a sloped surface. The rotor may also have a flange which deforms and fits within an annular notch of the stator.
