Experts,

What are the materials commonly used in electrical driven centrifugal pumps(Case, impeller, shaft) in CO2 capture amine units (H2S and chlorides free gas) ?

Google is your friend - pump material for amine.

The recommended elastomer for an Amine applications is Aflas. It has been a while since I did pump selections for Amine pumps so I don't remember if we used carbons steel or 316 SS for the wetted parts. You don't want any of the copper alloys since amine attacks copper, but any of your iron, carbon, or alloy steels should be suitable.

I was thinking more likely dressed in gold chains, rings, alligator shoes, greased hair and dark sun glasses.

Oh. I see. I don't know any, so I was just guessing.
