CAUTION! Operating temperature limitations are as follows:
Materials
Santoprene
Excellent abrasion resistance.
Hytrel
Virgin PTFE Chemically inert, virtually impervious. Very few chemicals are known to react chemically
with PTFE: molten alkali metals, turbulent liquid or gaseous uorine and a few uoro-chemicals such
as chlorine triuoride or oxygen diuoride which readily liberate free uorine at elevated temperatures.
PVDF
Polypropylene
Conductive Acetal
For specic applications, always consult the Warren Rupp “Chemical Resistance Chart”
CAUTION: Nonmetallic pumps and plastic components are not UV stabilized. Ultraviolet
radiation can damage these parts and negatively affect material properties. Do not expose
to UV light for extended periods of time.
®
Injection molded thermoplastic elastomer with no fabric layer. Long mechanical ex life.
®
: Good on acids, bases, amines and glycols at room temperatures only.

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.
