Abstract
A labyrinth seal device formed of a rotor and a stator connected together by an annular protrusion located within a recess. The rotor has a slinger located on the housing side of the rotor/stator interface. The stator has a plurality of alternating annular ridges and grooves which, together with an axial groove, direct fluid back into the housing to which the stator is attached. One of the ridges is positioned within the slinger recess, such that fluid traveling along a shaft to which the rotor is attached is slung off the slinger into the annular groove.
