Performance based on the following: elastomer fitted pump, flooded suction, water at ambient conditions.
The use of other materials and varying hydraulic conditions may result in deviations in excess of 5%.
Material Profile: Operating
Temperatures:
Max. Min.
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.
190°F
88°C
-10°F
-23°C
Santoprene®: Injection molded thermoplastic elastomer with
no fabric layer. Long mechanical flex life. Excellent abrasion
resistance.
275°F
135°C
-40°F
-40°C
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:
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.
