Our wastewater treatment center provides treatment to all plant runnoff. We are a soda bottling plant where the runoff is dilute soda (ph-3.8-5.0), line lube, sugar water, sanitation caustic, facultative anaerobes aka natural flora, small fragments of plastic aluminum wood. They are centrifigual pumps with a SS impelar and cast iron housing. We have had two pumps go out that are 2 years old. On both pumps the cast iron housings have been corroded away while the SS impelar is fine. My question is with such acidic solution (ph-3.8-5.0; temp - 50-70 F) should the pump housing been made out of SS?

You may have answered your own question, if the St Steel Impeller is fine, ten i would say yes, go for a St Steel casing also !! You will find that the cost difference in this day and age is not as big as it was a few years ago, and most chemical pump companies use St Steel as a base material now.
Hope this helps

I can't understand why the cost of a SS impeller was put in an iron case in the first place.
