✦ Synopsis

typically seals liquids such as lubricating oil from the surrounding atmosphere. Several seals have been designed where the faces have a "pumping" action i.e. the face in contact with the shaft acts to pump the liquid back towards the sealed area when the shaft is rotating, These face designs include ribs and groove portions orientated in the direction of shaft rotation. Unfortunately, this orientation means that the sealed fluid is only pumped back when the shaft is rotating in one direction. made from a semi-rigid material it exhibits much better wearing properties that increase the life of the shaft seal. Static area enhances seal's life Elastomers or other flexible materials are Title: Mechanical seal for water pump of heavy site also contains a good technical information section, which covers topics such as seal face materials, barrier and buffer fluids for dual seals and O-ring elastomer selection. Sealing Technology No.
