CAUTION! Operating temperature limitations are as follows:

Operating Temperatures

CAUTION: Nonmetallic pumps and plastic components are not UV stabilized. Ultraviolet radiation can damage these parts and negatively affect material properties.

Do not expose to UV light for extended periods of time.

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.

PVDF A durable uoroplastic with excellent chemical resistance. Excellent for UV applications. High tensile strength and impact resistance.

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.

PTFE Chemically inert, virtually impervious. Very few chemicals are known to react chemically with PTFE: molten alkali metals, turbulent liquid or gaseous

uorine and a few uoro-chemicals such as chlorine triuoride or oxygen diuoride which readily liberate free uorine at elevated temperatures.

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°F) will attack FKM.

Santoprene

Injection molded thermoplastic elastomer with no fabric layer. Long mechanical ex life. Excellent abrasion resistance.

Polypropylene A thermoplastic polymer. Moderate tensile and ex strenght. Resists strong acids and alkalie. Attacked by chlorine, fuming nitric acid and

other strong oxidizing agents.

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.
