A drained seal for sealing, from the ambient, a pressurized fluid in the interior of a housing fitted with a rotatable shaft and for eliminating fluid leakage along the shaft. The seal is a drained face seal that minimizes or eliminates leakage from between the sealing faces and onto the shaft. The seal includes a drain cavity formed in the stator, a drain port formed in the seal cup, a sealing dam adjacent to the drain cavity, and a tapered rotor which cooperate to prevent fluid leakage.
