Chemical resistance table

The resistance of a material to corrosion is a key criterion in material selection for components in centrifugal pumps. The complex collective load profile of the materials calls for a highly differentiated approach and many years of experience when making selections.

Chemical resistance tables are often used as a basic guide. The table below is intended as a guide for material selection solely from a corrosive stress perspective. Other criteria, such as economic efficiency, are not taken into account here at all.

The table covers only cast metal materials such as those used by KSB for the pump casing and impellers. When selecting materials for other product types, please refer to the relevant technical literature (e.g. DECHEMA materials table). This applies equally to plastics and engineering ceramics.
