Welded Metal Bellows

Metal bellow can operate in extremely high or low temperatures- they are formed to operate at far below their elastic limits, adding greatly to their reliability in extreme conditions. They can be installed anywhere - as simple seal or cartridge- in single, tandem, or double acting arrangements. Exotic materials layers can be function specific to resist corrosion, temperature, provide spring tension. Seals fluid pressure spring pressure can be resisted to heretofore unattainable levels. If one bellow layer fails other layers can carry on it.

 

Style MBC-609DIN Metal bellow seals

mbc690STYLE MBC609 DIN seal is specifically designed for the most demanding of High and Low temperature services as well as being suitable for high speed application in a wide range of media. The stationary configuration, in which the flexible bellows element is fixed into the equipment casing, eliminates damaging swashing motion due to casing distortion or shaft deflection. It also insulates the flexible element from direct shaft vibration and promotes more positive sealing while significantly extending seal life. Edge welded, heat treated high temperature metal bellows, integrally balanced, static die-formed graphite secondary seal,
