For specic applications, always consult “Chemical Resistance Chart" Technical Bulletin
Nitrile General purpose, oil-resistant. Shows good solvent, oil, water and hydraulic uid 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 uorine and a few uoro-chemicals such as
chlorine triuoride or oxygen diuoride which readily liberate free uorine 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 ex life. Excel-
lent abrasion resistance.
Maximum Minimum
‡
CF-8M Stainless Steel equal to or exceeding ASTM specication A743 for corrosion resistant iron chro-
mium, iron chromium nickel, and nickel based alloy castings for general applications. Commonly referred
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 specication for nickel and nickel alloy castings.
