ABSTRACT:
A floating seal arrangement is provided between the drive shaft of an electric motor and the cover plate of an inducer housing, through which the shaft extends. This allows radial movement of the shaft within the housing opening, while at the same time preventing the migration of a liquid from the inducer housing to the motor.
