Single seals allow for a containment’s level of emissions suitable for limited heavy-duty applications in terms of emissions of pollutants. The emissions come from the liquid film that is established between the seal faces to get adequate lubrication, the liquid can vaporize to the heating effect between the faces accelerating the dispersion. Fluiten has developed systems of single mechanical seals, Atex certified, for those uses in which the process fluid is at risk of fire, but there are no high environmental risks.
The mechanical seal SC, single with double hydraulic balancing and multiple springs external to the process fluid, is provided with a flange, shaft sleeve and fixed compass auxiliary cartridge in preparation and in accordance with the requirements of API 682.
