Metal Bellows Mechanical Seal

Metal Bellows Mechanical Seal

The metal bellows for our metal bellows mechanical seal is made using rolled sheet metal. Each piece of sheet metal is punched into ring type, S-shaped profile, and a metal bellows is achieved by overlaying and welding the sheet metals together. The two ends of the metal bellows is welded with the driving-base and the rotating ring together respectively.
A metal bellows mechanical seal has advantages that it requires no auxiliary sealing ring, and comes with wide working temperature range from -200℃ to 600℃. In addition, it offers good adaptability to the axis’s vibration and swing at high speed conditions, and also offers good compensation ability to make sure the sealing surfaces are in well condition.
