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

Grounding the Pump

To be fully groundable, the pumps must be ATEX Compliant. Refer to the nomenclature page for ordering information.

Optional 8 foot long (244 centimeters) Ground Strap is available for easy ground connection.

To reduce the risk of static electrical sparking, this pump must be grounded. Check the local
electrical code for detailed grounding instruction and the type of equipment required.

Refer to nomenclature page for ordering information.

WARNING

Take action to prevent static sparking.

Fire or explosion can result, especially
when handling ammable liquids. The
pump, piping, valves, containers or

other miscellaneous equipment must
be grounded.

Ambient temperature range: -20°C to +40°C
Process temperature range: -20°C to +80°C for models rated as category 1 equipment

In addition, the ambient temperature range and the process temperature range do not exceed the operating temperature range of the applied non-metallic parts as listed in the manuals of the pumps.

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.

Metals:

Alloy C: Equal to ASTM494 CW-12M-1 specication for nickel and nickel alloy.

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.

The main directional (air) control valve

As inner chamber pressure

together creating discharge on one side and suction on the
opposite side. The discharged and primed liquid’s directions

are controlled by the check valves (ball or ap)

The pump primes as a result of the suction stroke. The
suction stroke lowers the chamber pressure
the chamber volume. This results in a pressure differential
necessary for atmospheric pressure
through the suction piping and across the suction side check

valve and into the outer uid chamber

Suction (side) stroking also initiates the reciprocating
(shifting, stroking or cycling) action of the pump. The suction
diaphragm’s movement is mechanically pulled through its
stroke. The diaphragm’s inner plate makes contact with an
actuator plunger aligned to shift the pilot signaling valve.
Once actuated, the pilot valve sends a pressure signal to the
opposite end of the main directional air valve, redirecting the
compressed air to the opposite inner chamber.

Pump can be submerged if the pump materials of construction

must be piped above the liquid level. When the pumped product

source is at a higher level than the pump (ooded suction

prevent siphoning spills.
