What are the advantages and disadvantages of the bronze impeller and stainless steel impeller of the pump? Is the price gap big?
Stainless steel used in some acid and alkali occasions. Or the need for clean water.Of course, these materials than the cast iron wear resistance will be better!
The price of bronze is less than that of 304 stainless steel, and 316 will be more expensive.Fire is most often used copper impeller (65, 85 copper prices are different)
The resistance of bronze to sea water is better than that of stainless steel (304316). Stainless steel is afraid of pitting of CL.
From the point of view of the material itself, the bronze has a low temperature resistance, and the strength of the 100 degrees below zero will not decrease in any way. For stainless steel, chilling temperatures, brittle like glass. At room temperature, the mechanical strength of stainless steel is higher.
