ABSTRACT:
A seal arrangement for sealing a shaft with respect to a housing containing a fluid comprises a face seal exposed to a buffer gas on a portion thereof facing away from the fluid. Disposed upstream of the face seal at the fluid said portion thereof is a collecting chamber for receiving a leakage of the buffer gas having gained access to the fluid-side portion of the face seal. The collecting chamber is in communication with an external separating means for separating the gas phase from the fluid phase of a gas/fluid mixture having collected in the collecting chamber. The fluid phase can be returned into the interior of the housing.
