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.

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.

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

-20°C to +100°C for models rated as category 2 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.

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

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.

Air Inlet

The air exhaust should
be piped to an area
for safe disposition
of the product being

pumped, in the event of

a diaphragm failure.

Installation And Start-Up

Locate the pump as close to the product being pumped as possible. Keep the suction line length and number of ttings to a minimum. Do not reduce the suction line

diameter.

Air Supply

Connect the pump air inlet to an air supply with sufcient capacity and pressure to achieve desired performance. A pressure regulating valve should be installed to

insure air supply pressure does not exceed recommended limits.

Air Valve Lubrication
The air distribution system is designed to operate WITHOUT lubrication. This is the standard mode of operation. If lubrication is desired, install an air line lubricator
set to deliver one drop of SAE 10 non-detergent oil for every 20 SCFM (9.4 liters/sec.) of air the pump consumes. Consult the Performance Curve to determine air
consumption.

Air Line Moisture
Water in the compressed air supply may cause icing or freezing of the exhaust air, causing the pump to cycle erratically or stop operating. Water in the air supply can
be reduced by using a point-of-use air dryer.

Air Inlet And Priming

To start the pump, slightly open the air shut-off valve. After the pump primes, the air valve can be opened to increase air ow as desired. If opening the valve
increases cycling rate, but does not increase the rate of ow, cavitation has occurred. The valve should be closed slightly to obtain the most efcient air ow to pump
ow ratio.

Diaphragm Servicing

Step 1: With manifolds and outer chambers
removed, remove diaphragm assemblies from dia­phragm rod. DO NOT use a pipe wrench or similar
tool to remove assembly from rod. Flaws in the rod
surface may damage bearings and seal. Soft jaws
in a vise are recommended to prevent diaphragm
rod damage.

Step 1.A: NOTE: Not all inner diaphragm plates
are threaded. Some models utilize a through hole in
the inner diaphragm plate. If required to separate dia­phragm assembly, place assembly in a vise, gripping
on the exterior cast diameter of the inner plate. Turn
the outer plate clockwise to separate the assembly.

Outer plate with a threaded stud, diaphragm, and
an inner plate with through hole. Secure threaded
inner plate in a vise. Ensure that the plates are being
installed with the outer radius against the diaphragm.

Step 3: Lightly lubricate, with a compatible material,
the inner faces of both outer and inner diaphragm plates
when using on non Overlay diaphragms (For EPDM
water is recommended). No lubrication is required.

Step 4: Push the threaded outer diaphragm
plate through the center hole of the diaphragm.
Note: Most diaphragms are installed with
the natural bulge out towards the fluid side.

Step 7: Install diaphragm rod assembly into
pump and secure by installing the outer cham­ber in place and tightening the capscrews.

Step 8: On opposite side of pump, thread the
remaining assembly onto the diaphragm rod. Us­ing a torque wrench, tighten the assembly to the
diaphragm rod. Align diaphragm through bolt holes,
always going forward past the recommended torque.
Torque values are called out on the exploded view.
NEVER reverse to align holes, if alignment cannot
be achieved without damage to diaphragm, loosen
complete assemblies, rotate diaphragm and reas­semble as described above.

Always inspect diaphragms for wear cracks or
chemical attack. Inspect inner and outer plates for
deformities, rust scale and wear. Inspect intermediate
bearings for elongation and wear. Inspect diaphragm
rod for wear or marks.
Clean or repair if appropriate. Replace as required.

Step 2: Reassembly: There are two different types
of diaphragm plate assemblies utilized throughout the
Sandpiper product line: Outer plate with a threaded
stud, diaphragm, and a threaded inner plate.

sb1dl5sm-rev0614

Step 5: Thread or place, outer plate stud into
the inner plate. For threaded inner plates, use a
torque wrench to tighten the assembly together.
Torque values are called out on the exploded view.

Repeat procedure for second side assembly. Allow
a minimum of 15 minutes to elapse after torqu­ing, then re-torque the assembly to compensate
for stress relaxation in the clamped assembly.

Step 6: Thread one assembly onto the diaphragm
rod with sealing washer (when used) and bumper.
