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
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 gas line,
bleed the pressure, and disconnect the gas 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.
Gasborne particles and loud noise hazards. Wear eye and ear
protection.
In the event of diaphragm rupture, pumped material may
enter the gas end of the pump, and be discharged into the
atmosphere. If pumping a product that is hazardous or toxic,
the gas 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 gas 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 Prole:
CAUTION! Operating temperature limitations are as follows:
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.
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.
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 triuoride or oxygen
diuoride 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:
Stainless Steel: Equal to or exceeding ASTM specication 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.
Forspecicapplications,alwaysconsulttheChemicalResistanceChart.

2: INSTAL & OP
The pump must be rigidly mounted in the horizontal position with
fasteners to a conductive base or natural ground.
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.
Gas Supply
Connect the pump gas inlet to an gas supply with sufcient capacity and pressure to achieve desired performance. A pressure regulating valve should be installed to
insure gas supply pressure does not exceed recommended limits.
Gas Valve Lubrication
The gas distribution system is designed to operate WITHOUT lubrication. This is the standard mode of operation. If lubrication is desired, install an gas line lubricator
set to deliver one drop of SAE 10 non-detergent oil for every 20 SCFM (9.4 liters/sec.) of gas the pump consumes. Consult the Performance Curve to determine gas
consumption.
Gas Line Moisture
Water in the compressed gas supply may cause icing or freezing of the exhaust gas, causing the pump to cycle erratically or stop operating. Water in the gas supply
can be reduced by using a point-of-use gas dryer.
Gas Inlet And Priming
To start the pump, slightly open the gas shut-off valve. After the pump primes, the gas valve can be opened to increase gas 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 efcient gas ow to pump
ow ratio.

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.

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.
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.
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. S05,
S07, and S10 non–metallic units are installed
with the natural bulge in towards the gas side.
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.
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.

PUMPING HAZARDOUS LIQUIDS
When a diaphragm fails, the pumped liquid or fumes enter the natural gas
end of the pump. Fumes are exhausted into the surrounding environment. When
pumping hazardous or toxic materials, the exhaust gas must be piped to an
appropriate area for safe disposal. See illustration #1 at right.
This pump can be submerged if the pump materials of construction are
compatible with the liquid being pumped. The natural gas exhaust must be
piped above the liquid level. See illustration #2 at right. Piping used for the gas
exhaust must not be smaller than 1" (2.54 cm) diameter. Reducing the pipe size
will restrict natural gas ow and reduce pump performance. When the pumped
product source is at a higher level than the pump (ooded suction condition), pipe
the exhaust gas higher than the product source to prevent siphoning spills. See
illustration #3 at right.
PIPING THE NATURAL GAS EXHAUST
The following steps are necessary to pipe the exhaust gas away from the
pump.The gas distribution valve assembly (item 1) has 1" NPT threads for piped
exhaust.
IMPORTANT INSTALLATION NOTE: The manufacturer recommends
installing a exible conductive hose or connection between the pump and any
rigid plumbing. This reduces stresses on the molded threads of the natural gas
exhaust port. Failure to do so may result in damage to the natural gas distribution
valve body.
Any piping or hose connected to the pump’s natural gas exhaust port must
be conductive and physically supported. Failure to support these connections
could also result in damage to the valve body.
If a high pressure gas spike is possible through the exhaust line, a pressure
regulator is required in the exhaust piping.
