RECYCLING
Many components of BLAGDON air operated double diaphragm pumps are made of recyclable materials. We encourage pump
users to recycle worn out parts and pumps whenever possible, after any hazardous pumped fluids are thoroughly flushed.

Caution - Operating temperature limitations are as follows:
Materials
Buna-n - 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 oils and solvents, but is fair on
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 oxidising acids, ketones, esters, nitro hydro carbons and
chlorinated aromatic hydrocarbons.
Santoprene® - Injection moulded thermoplastic elastomer with no fabric layer. Long mechanical flex life.
Excellent abrasion resistance.
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.
Viton® - Shows good resistance to a wide range of oils and solvents : especially all alphatic, aromatic and
halogenated hydrocarbons, acids, animal and vegetable oils.
Polypropylene - High strength, light weight, corrosion resistant polyolefin which easily withstands most chemi-
cals, with no known solvent at room temperature.
