Material of the pump impeller
Thread Content
What is the common material used for pump impellers? What material is the bearing made of?
It mainly depends on the type of pump; there are many materials available for the impeller. Those we have encountered include steel (including ordinary carbon steel, cast iron, stainless steel, CD4MCu, Cr30, etc.), plastic, and graphite. Bearing steel is a special-purpose steel (bearing steel).

Bearing steel is a special-purpose steel (bearing steel) ； Cast iron is rarely used; a specific analysis is required depending on the actual operating conditions.
The material of the impeller is primarily chosen based on considerations such as corrosion resistance, abrasion resistance, cavitation resistance, and mechanical properties
Check what medium is being used! Different media require different material specifications!
It is generally selected based on operating conditions; for specific details, refer to API610.
Check what medium is being used! Different media require different material specifications! Of course, cost considerations also need to be taken into account.
