Wastewater Treatment Cast Iron Pump Problem

Wastewater Treatment Cast Iron Pump Problem

Wastewater Treatment Cast Iron Pump Problem

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?
