Air Operated Double Diaphragm Pump 6/05 Page 1
Buna N 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 190°F -10°F
hydrocarbons and nitro hyrdrocarbons. 88°C -23°C
EPDM Shows very good water and chemical resistance. Has poor resistance to oil and solvents, 280°F -40°F
but is fair in ketones and alcohols. 138°C -40°C
Neoprene All purpose. Resistant to vegetable oil. Generally not affected by moderate chemicals,
fats, greases and many oils and solvents. Generally attacked by strong oxidizing acids, ketones, 200°F -10°F
esters, nitro hydrocarbons and chlorinated aromatic hydrocarbons. 93°C -23°C
Santoprene
®
Injection molded thermoplastic elastomer with no fabric layer. Long mechanical flex 275°F -40°F
life. Excellent abrasion resistance. 135°C -40°C
Virgin 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 220°F -35°F
chlorine trifluoride or oxygen difluoride which readily liberate free fluorine at elevated temperatures. 104°C -37°C
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 350°F -40°F
(over 70°F) will attack Viton. 177°C -40°C
Polypropylene 180°F 32°F
82°C 0°C
