Safety Information

IMPORTANT

Read the safety warnings and instructions in this manual
before pump installation and start-up. Failure to comply with
the recommendations stated in this manual could damage the
pump and void factory warranty.

When the pump is used for materials that tend to settle out

or solidify, the pump should be ushed after each use to

prevent damage. In freezing temperatures the pump should be
completely drained between uses.

CAUTION

Before pump operation, inspect all fasteners for loosening

caused by gasket creep. Retighten loose fasteners to prevent
leakage. Follow recommended torques stated in this manual.

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.

WARNING
Pump not designed, tested or certied to be powered by
compressed natural gas. Powering the pump with natural
gas will void the warranty.

WARNING

When used for toxic or aggressive uids, the pump should
always be ushed clean prior to disassembly.

Before maintenance or repair, shut off the compressed air line,
bleed the pressure, and disconnect the air line from the pump.

Be certain that approved eye protection and protective clothing
are worn at all times. Failure to follow these recommendations
may result in serious injury or death.

Airborne particles and loud noise hazards. Wear eye and
ear protection.

In the event of diaphragm rupture, pumped material may enter
the air end of the pump, and be discharged into the atmosphere.
If pumping a product that is hazardous or toxic, the air exhaust

must be piped to an appropriate area for safe containment.

Take action to prevent static sparking. Fire or explosion can

result, especially when handling ammable liquids. The pump,
piping, valves, containers and other miscellaneous equipment

must be properly grounded.

This pump is pressurized internally with air pressure during
operation. Make certain that all fasteners are in good condition
and are reinstalled properly during reassembly.

kg

Use safe practices when lifting.

Materials

Material Prole:

CAUTION! Operating temperature limitations are as follows:

Conductive Acetal: Tough, impact resistant, ductile. Good
abrasion resistance and low friction surface. Generally inert, with
good chemical resistance except for strong acids and
oxidizing agents.

EPDM: Shows very good water and chemical resistance. Has
poor resistance to oils and solvents, but is fair in ketones and
alcohols.

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(21°C)) will
attack FKM.

Hytrel®: Good on acids, bases, amines and glycols at room
temperatures only.

Neoprene: All purpose. Resistance to vegetable oils. Generally
not affected by moderate chemicals, fats, greases and many
oils and solvents. Generally attacked by strong oxidizing acids,
ketones, esters and nitro hydrocarbons and chlorinated
aromatic hydrocarbons.

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.

Nylon: 6/6 High strength and toughness over a wide
temperature range. Moderate to good resistance to fuels, oils
and chemicals.

Polypropylene: A thermoplastic polymer. Moderate tensile

and ex strength. Resists stong acids and alkali. Attacked by

chlorine, fuming nitric acid and other strong oxidizing agents.

PVDF: (Polyvinylidene Fluoride) A durable uoroplastic with

excellent chemical resistance. Excellent for UV applications.
High tensile strength and impact resistance.

Santoprene®: Injection molded thermoplastic elastomer with no
fabric layer. Long mechanical ex life. Excellent
abrasion resistance.

UHMW PE: A thermoplastic that is highly resistant to a broad
range of chemicals. Exhibits outstanding abrasion and impact
resistance, along with environmental stress-cracking resistance.

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

Virgin PTFE: (PFA/TFE) Chemically inert, virtually impervious.
Very few chemicals are known to chemically react 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.

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.

Stainless Steel: Equal to or exceeding ASTM specication A743 CF-8M 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.

IMPORTANT

When the pumped product source is at a higher

level than the pump (ooded suction condition),

pipe the exhaust higher than the product source
to prevent siphoning spills. In the event of a
diaphragm failure a complete rebuild of the
center section is recommended.
