CHEMICAL RESISTANCE DATA
These recommendations are based upon information from material suppliers and careful examination of available published information and are
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, this information should be considered as a general guide rather than an unqualified guarantee. Ultimately,
the customer must determine the suitability of the pump used in various solutions. All recommendations assume ambient temperatures unless
otherwise noted.
The ratings for these materials are based upon the chemical resistance only. Added consideration must be given to pump selections when the
chemical is abrasive, viscous in nature, or has a Specific Gravity greater than 1.1.
