Metal bellows seals perform many functions. Unfortunately all the functions are not available in the same seal.

They can be used to eliminate elastomers (rubber like parts) in the chemical process industry. Most chemicals and chemical combinations can be sealed with either a good grade of Viton® or ethylene propylene, but someone has to make the decision and many responsible people are not capable, so mistakes are often made.

Metal bellows are also used to eliminate elastomers because of temperature limits. All elastomers have both an upper and lower temperature limit that prevents them from sealing many hot resins, polymers and cryogenic applications. Hot oils are another high temperature sealing problem, but their cokingcharacteristics dictates cooling of the stuffing box area.

The individual bellows convolutions can be formed in different ways:

 

Operating Limits:

Pressure: ≤ 2.5 MPa

Speed: ≤ 20 m/s

Temperature: -30℃+180℃


Materials:

● Rotary Ring :  Carbon, Sic, SSic, TC 

● Stationary Ring : Ceramic, Sic,TC

● Secondary Seal : NBR,EPDM,VITON, Kalrez.

● Spring & Other Parts : SUS304/SUS316/AM350, HAST .C.

Most often metal bellows seals are thought of as High Temperature seals. But metal bellows seals are often effective in a wide range of other seal applications. The most common of these is chemical, general water pump applications. For many years an inexpensive form of metal bellows seals have been used very successfully in the waste water / sewage industry and in the agricultural fields pumping irrigation water. These seals were generally made of a formed bellows rather than a welded bellows. Welded bellows seals are much stronger and have superior flex and recovery characteristics which are more ideal to holding seal faces together but cost more to manufacture. Welded metal bellows seals are less prone to metal fatigue ...
