Materials
Operating Temperatures
For specific applications, always consult “Chemical Resistance Chart" Technical Bulletin
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.
EPDM Shows very good water and chemical resistance. Has poor resistance to oil and solvents, but is fair in
ketones and alcohols.
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 hydrocar-
bons.
HYTREL
®
Good on acids, bases, amines and glycols at room temperature.
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. Excel-
lent abrasion resistance.

‡
CF-8M Stainless Steel equal to or exceeding ASTM specification A743 for corrosion resistant iron chro-

to as 316 Stainless Steel in the pump industry.

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.
ALLOY C CW-12MW equal to or exceeding ASTM A494 specification for nickel and nickel alloy castings.
