12 Bellows Convolutions
- Many (not all) mechanical seal suppliers produce edge welded
metal bellows with an 8 convolute stack. AESSEAL® produces
a 12 convolute bellows as standard. Maximum convolutions mean
maximum seal life.
The bellows range of seals were created with the aid of the
latest Computer Aided Design and Manufacture programmes including
Finite Element Analysis (FEA). This helped to predict how the
seal would perform under various conditions and also helped
decide on the best bellows convolution profile, which is optimized
at 45° on the inside diameter. |
