Materials
CAUTION!
Operating temperature limitations are as follows:
Ambient temperature range
-20 C to +40 C
Process temperature range
-20 C to +80 C for models rated as category 1 equipment
-20 c to +100 C for model rated as category 2 equipment
In addition, the ambient temperature range and the process temperature range do not
exceed the operating temperature range of the applied non-metallic parts as listed in the
manuals of the pumps .
For specific applications, always consult the Chemical Resistance Chart.
Note:
This document is a high level guide. Please be aware that not all model and or material
combinations are possible for all sizes. Please consult factory or your distributor for specific details.

Virgin PTFE:
(PFA/TFE) Chemically inert, virtually impervious .
Very few chemicals are known to chemically react with PTFE;
molten alkali metals, turbulent liquid or gaseous fluorine and
a few fluoro-chemicals such as chlorine trifluoride or oxygen
difluoride which readily liberate free fluorine at elevated
temperatures .

Maximum and Minimum Temperatures are the limits for which these materials can be operated.
Temperatures coupled with pressure affect the longevity of diaphragm pump components.
Maximum life should not be expected at the extreme limits of the temperature ranges.
