Abstract
A seal assembly for sealing a space between a rotating shaft and a housing. In this regard, the seal assembly includes a rotating component connected to the shaft, and a stationary component connected to the housing. A first seal is connected to the rotating component and a second seal is connected to the stationary component. The first seal includes at least one dispersion member that generates a fluid disturbance in a region adjacent the space during rotation of the rotating component and a discontinuity that provide a pathway for a contaminant to exit the space.
