Operating Temperatures
PTFE 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.
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.

Dimension A
Standard Pump 7" (178)
Pulse Output Kit 7.9/16" (192)
EPDM Shows very good water and chemical resistance. Has poor resistance to oil and solvents,
but is fair in ketones and alcohols. 212 °F+ -10 °F 50 °F to 212°F
100 °C+ -23 °C 10 °C to 100°C
SANTOPRENE ® Injection molded thermoplastic elastomer with no fabric layer. Long mechanical
flex life. Excellent abrasion resistance.
212 °F+ -10 °F 50 °F to 212°F
100 °C+ -23 °C 10 °C to 100°C
BUNA-N 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.
VITON ® 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 Viton ® .
190 °F -10 °F 50 °F to 140°F
88 °C -23 °C 10 °C to 60°C
212 °F+ +32 °F 75 °F to 212°F
