SANDPIPER RHDF2 Metallic - Manual (Page 3)

rhdf2dl1sm-rev0614 Model RHDF2 Page 1
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 oil. 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.
Santoprene ®: : Injection molded thermoplastic elastomer with no fabric layer. Long mechanical flex life.
Excellent abrasion resistance.
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 chlorine trifluoride or oxygen difluoride which readily liberate free fluorine 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.
Polypropylene:
UHMW Polyethylene:
HYTREL ® Good on acids, bases, amines and glycols at room temperature.

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.
