SDK40 – labyrinth seal system with non split housings and radial adjustable sealing rings

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.
