Materials
Operating Temperatures
For specific applications, always consult “Chemical Resistance Chart" Technical Bulletin
Nitrile/FDA White 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.
EPDM Shows very good water and chemical resistance. Has poor resistance
to oil and solvents, but is fair in ketones and alcohols.
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.
HYTREL ® Good on acids, bases, amines and glycols at room temperature.
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.
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 flex life. Excellent abrasion resistance.

CF-8M Stainless Steel equal to or exceeding ASTM specification A743 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.
To order a pump or replacement parts, first enter the Model Number MHDF1, or MHDF25, followed by the Type Designation listed below in the far left column.
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.
