Salt Water Pumps
Hello to the great minds at CE.
I work alot with pumps. How would a stainless steel impeller or shaft stand up in salt water conditions?
I have soem idea but feel free to tell me what you know.

More info needed. Salt concentration, temperature and whether the fluid is static for long. Also the grade of SS used. Coorosion depends a lot on operating conditions. Generally for sea water at temperatures below 50C and continuously flowing (satuarated with dissolved air) 306 SS should work without problem.CE DesignerHello to the great minds at CE.

ISHAN TOPREYou see, stainless steel has 16% chromium. So it is well guarded against salinity. These pumps are widely used in many places. What is the idea behind you asking this query?

CE DesignerJust exploring possibilities. Currently we use SS for the shaft only, just trying to figure out, lets say how a SS impeller will perform in salt water. I cant say what temperatures but they run between 1200-1800 RPM. Sandy environment.
