Selection of agitator seal

Selection of agitator seal

Selection of agitator seal

(OP)
Hi all,

I am working with an extremely aggresive chemical in a G/L reactor above 100C. Now I have problem selecting a suitable agitator seal. We have tested almost all fluoroelastomers like Kalrez, Chemraz etc. used in mechanical seals. Vapors of this chemical attacks all of these elastomers.

I am wondering what are my options now. Can you suggest me any other elastomer that I should try? Also do you know if it is possible to use mag drive agitator (w/ vendor info), which doesn't have any elastomer? What other options I can use like gas seal or a seal with gas purge etc? Let me know if you have experience with any of these alternatives or if you have any other suggestions.

Thanks much in advance.

RE: Selection of agitator seal

Call Seals Eastern and talk to them about Aflas.
Don't talk to anyone else.  If this won't work then you need a solid metallic system.
