The shaft seal type SDK40 is used in order to seal technical gases, dust and vapour mainly in tubines, compressors and other high pressure devices with sub- and overcritical rotors.
Use of the SDK80 can reduce leakage rates by up to 90%. The technical design of this sealing system is subject to meticulous information about the operating conditions and about the characteristic data of materials.SDK40 is a labyrinth seal system with non split housings and radial adjustable sealing rings. Compared to a rigid lip seal, the SDK40 is significantly more efficient, especially with supercritical rotors.
