Abstract
A sealing system includes a first seal, a second seal spaced apart from the first seal and a sealing chamber defined between the first and second seals. The sealing chamber is fluidly connected to a vacuum source. In operation, the sealing chamber is maintained at a pressure that is below atmospheric pressure. Contaminants that breach one of the first and second seals are pulled into the sealing chamber and removed by the vacuum source.
