CHEMICAL RESISTANCE GUIDE

This chart has been compiled from Sigmamotor Inc.’s study of a variety of sources. As such the information contained within is, at the date of issuance, believed to be accurate. However, since the resistance of metals, plastics and elastomers can be affected by concentration, temperature, presence of other chemicals and other factors the information should be considered a general guide not an unqualified guarantee. Sigmamotor Inc. therefore does not express or imply any warranty. Ultimately it is the users responsibility to determine the suitability of the pump used for various solutions.
