ABSTRACT:
A non-contacting shaft seal for preventing the flow of fluid through a shaft passageway in a housing wall includes a collar fixedly attached to a rotating shaft for creating a zone of turbulence around the passageway. The collar has a diameter larger than the diameter of the shaft passageway and is slightly physically spaced from the housing wall to confine the turbulence to the area between the collar and the housing wall to thereby create a generally annularly shaped zone of turbulence or turbulence barrier around the passageway.
