Materials

Operating Temperatures

For specic 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.

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.

Urethane

Shows good resistance to abrasives. Has poor resistance to most solvents and oils.

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 specication 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.

190°F -10°F

88°C -23°C

200°F -10°F

93°C -23°C

150°F +32°F

66°C 0°C

275°F -40°F

135°C -40°C

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.
