A seal cartridge (10) adapted to be mounted upon a rotating shaft (30), including a rotor (12) and a stator (40), the rotor and stator being arrange d to create a labyrinth portion (A) and a contact portion (B). The rotor includes a radially outwardly directed surface (18) and the stator includes a flange (5 6) biased toward the rotor surface to create the contact portion. The rotor and stator create a labyrinth portion with a pair of inwardly facing ridges (51, 53) positioned within a pair of outwardly facing grooves (15, 17). The stator may include a should er (44) for positioning the seal cartridge with respect to the housing, or instead a sloped surface. A spring may be used to bias the flange firmly toward the contact surface of the rotor. The rotor may also have a flange (14) which deforms an d fits within an annular notch (50) of the stator.
