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

Neoprene:
All purpose. Resistance to vegetable oils. Generally
not affected by moderate chemicals, fats, greases and many
oils and solvents. Generally attacked by strong oxidizing acids,
ketones, esters and nitro hydrocarbons and chlorinated
aromatic hydrocarbons.

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.
Metals:
Alloy C:
Equal to ASTM494 CW-12M-1 specification for nickel and nickel alloy.
Stainless Steel:
Equal to or exceeding ASTM specification A743 CF-8M for corrosion
resistant iron chromium, iron chromium nickel and nickel based alloy castings for
general applications. Commonly referred to as 316 Stainless Steel in the pump industry.
For specific applications, always consult the Chemical Resistance Chart.
