Abstract
A centrifugal hydraulic seal between the rotating and non-rotating components of rotating process equipment is provided. The centrifugal hydraulic seal reduces toxic gases inside an operating machine from escaping to the atmosphere or reduces gas from the atmosphere entering into the operating machine by the placement of protruding vanes on the face of the rotating seal wall on the low pressure side of the seal.
