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.
Before permanent installation, test the equipment with the
chemicals and under the specific conditions of your application.
Ratings of chemical behavior listed in this chart apply at
a 48-hr exposure period.
PumpBiz does not warrant (neither express nor implied) that
the information in this chart is accurate or complete or that
any material is suitable for any purpose.
All recommendations assume ambient temperatures unless otherwise
Ratings - Chemical Effect
A - No effect-Excellent
B - Minor effect-Good
C - Moderate effect-Fair
D - Severe effect-Not recommended
1. P.V.C. - Satisfactory to 72° F.
2. Polypropylene - Satisfactory to 72° F.
3. Polypropylene - Satisfactory to 120° F.
4. Buna-N - Satisfactory for "O" Rings
5. Polyacetal - Satisfactory to 72° F.
6. Ceramag - Satisfactory to 72° F.
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.
Variations in chemical behavior during handling due to factors
such as temperature, pressure, and concentrations can cause
equipment to fail, even though it passed an initial test.
SERIOUS INJURY MAY RESULT.
Use suitable guards and/or personal protections when handling
