Chemical Resistance Data

The information below was gathered from several material and pump suppliers and a careful examination of available published information. We believe the information is fairly 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 components used in various solutions.

All recommendations assume ambient temperatures unless otherwise noted.

RATINGS - CHEMICAL EFFECT
A - No effect-Excellent
B - Minor effect-Good
C - Moderate effect-Fair
D - Severe effect-Not recommended

FOOTNOTES
1. P.V.C. - Satisfactory to 72ƒ F.
2. Polypropylene - Satisfactory to 72ƒ F.
3. Polypropylene - Satisfactory to 120ƒ F.
4. Buna-N - Satisfactory for "O" Rings
5. Polyacetal - Satisfactory to 72ƒ F.
6. Ceramag - Satisfactory to 72ƒ F.

The ratings for these materials are based upon the chemical resistance only. Added consideration must be given to component selections when the chemical is abrasive, viscous in nature, or has a Specific Gravity greater than 1.1.
