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 a flange 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 positioned within a pair of outwardly facing grooves. The stator may include a shoulder 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 which deforms and fits within an annular notch of the stator.
