Pump impeller material CL what is the foreign material?
The corrosive wear of impeller is mainly caused by corrosive gas and corrosive stress in the conveying medium of fan. There are different kinds of corrosion due to different media. In order to prevent corrosion and corrosion wear of the impeller, usually adopt the following measures: selection of corrosion resistance strong stainless steel impeller material; in the impeller surface coating or spray coating and improve the surface quality of the impeller in order to solve the problem of corrosion and wear.
Non-metallic material compositionPPS plastic, phenolic resin and so on.There is no domestic impeller made of phenolic resin. In the United States, SIMS company is specialized in making this kind of graphite based reinforced phenolic fiber material SIMSITE, and has been applied to the impeller of centrifugal pumps. Phenolic resin has excellent alkali resistance and is extremely suitable for pumping seawater.
Common material for impellerCast iron, bronze, stainless steel, manganese bronze, Monel alloy, INCONEL, and non metal materials.
