1. A shaft seal assembly comprising:
a. a stator configured to engage a housing, said stator comprising:
i. a stator main body;ii. a stator inward radial projection extending radially inward from said stator main body, wherein a distal end of said stator inward radial projection is configured to provide a stator/shaft clearance between said distal end of said stator inward radial projection and a shaft extending from said housing; and,iii. a collection groove adjacent said stator inward radial projection, wherein an inboard side of said stator inward radial projection forms an inboard wall of said collection groove; b. a rotor positioned within said stator, said rotor configured to engage said shaft, said rotor comprising:
i. a rotor main body;ii. a rotor axial projection extending from said rotor main body, wherein said rotor axial projection is positioned adjacent said distal end of said stator inward radial projection, wherein no surfaces of said rotor are directly exposed to an external environment. |
