CAUTION! Operating temperature limitations are as follows:

Operating Temperatures
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.
Nitrile
General purpose, oil-resistant. Shows good solvent, oil, water and hydraulic fluid resistance. Should not be used with highly polar solvents
like acetone and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.
PVDF
A durable fluoroplastic with excellent chemical resistance. Excellent for UV applications. High tensile strength and impact resistance.
NEOPRENE
All purpose. Resistant to vegetable oils. Generally not affected by moderate chemicals, fats, greases and many oils and solvents. Generally
attacked by strong oxidizing acids, ketones, esters, nitro hydrocarbons and chlorinated aromatic hydrocarbons.
PTFE
Chemically inert, virtually impervious. Very few chemicals are known to react chemically 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.
FKM (Fluorocarbon)
shows good resistance to a wide range of oils and solvents; especially all aliphatic, aromatic and halogenated hydrocarbons, acids,
animal and vegetable oils. Hot water or hot aqueous solutions (over 70°F) will attack FKM.
Santoprene
® Injection molded thermoplastic elastomer with no fabric layer. Long mechanical flex life. Excellent abrasion resistance.
Polypropylene
A thermoplastic polymer. Moderate tensile and flex strenght. Resists strong acids and alkalie. Attacked by chlorine, fuming nitric acid and
other strong oxidizing agents.

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.
