The material of stainless steel centrifugal pump is generally 304 stainless steel, and stainless steel is usually the abbreviation of stainless acid-resistant steel. After long-term use, stainless steel centrifugal pump needs to be cleaned and maintained when the pump is stopped.

Stainless steel centrifugal pumps are widely used in many industrial fields due to their excellent corrosion resistance. However, different media have different corrosiveness, so how to optimize the material and surface treatment of stainless steel centrifugal pumps for specific corrosive media to extend their service life is a problem worthy of attention.
