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 used for toxic or aggressive uids, the pump should
always be ushed clean prior to disassembly.
Airborne particles and loud noise hazards. Wear eye and ear
protection.
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.
ATEX compliant pumps are suitable for use in explosive atmospheres when the equipment is properly grounded
in accordance with local electrical codes. Pumps equipped with electrically conductive diaphragms are suitable for
the transfer of conductive or non-conductive uids of any explosion group. When operating pumps equipped with
non-conductive diaphragms that exceed the maximum permissible projected area, as dened in EN 13461-1: 2009
section 6.7.5 table 9, the following protection methods must be applied:
• Equipment is always used to transfer electrically conductive uids or
• Explosive environment is prevented from entering the internal portions of the pump, i.e. dry running
For further guidance on ATEX applications, please consult the factory.
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.
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.
CAUTION
WARNING
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.
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.
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.
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.

Air-Operated Double Diaphragm (AODD) pumps are powered
by compressed air or nitrogen.
The main directional (air) control valve ①distributes
compressed air to an air chamber, exerting uniform pressure
over the inner surface of the diaphragm
②. At the same time,
the exhausting air ③ from behind the opposite diaphragm
is directed through the air valve assembly(s) to an exhaust
port ④.
As inner chamber pressure (P1) exceeds liquid chamber
pressure (P2), the rod ⑤connected diaphragms shift
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)⑥orientation.
The pump primes as a result of the suction stroke. The
suction stroke lowers the chamber pressure (P3) increasing
the chamber volume. This results in a pressure differential
necessary for atmospheric pressure (P4) to push the uid
through the suction piping and across the suction side check
valve and into the outer uid chamber ⑦.
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.

Exhaust)
In the event of a diaphragm rupture, pumped fluid can enter the air center section
of the pump and exit through the air exhaust port. When pumping hazardous fluids,
it is recommended to pump the exhaust air to a safe location.
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.

Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.
Check valve obstructed. Disassemble the wet end of the pump and manually dislodge obstruction in the check valve pocket.
Check valve and/or seat is worn or needs adjusting. Inspect check valves and seats for wear and proper setting. Replace if necessary.
Entrained air or vapor lock in chamber(s). Purge chambers through tapped chamber vent plugs. Purging the chambers of air can be dangerous.
Product Leaking
Through Exhaust
Diaphragm failure, or diaphragm plates loose. Replace diaphragms, check for damage and ensure diaphragm plates are tight.
Diaphragm stretched around center hole or bolt holes. Check for excessive inlet pressure or air pressure. Consult Chemical Resistance Chart for compatibility
with products, cleaners, temperature limitations and lubrication.
Premature Diaphragm
Failure
Cavitation. Enlarge pipe diameter on suction side of pump.
Excessive ooded suction pressure. Move pump closer to product. Raise pump/place pump on top of tank to reduce inlet pressure.
Install Back pressure device (Tech bulletin 41r). Add accumulation tank or pulsation dampener.
Misapplication (chemical/physical incompatibility). Consult Chemical Resistance Chart for compatibility with products, cleaners, temperature limitations
and lubrication.
Incorrect diaphragm plates or plates on backwards,
installed incorrectly or worn.
Check Operating Manual to check for correct part and installation. Ensure outer plates have not been
worn to a sharp edge.
Unbalanced Cycling Excessive suction lift. For lifts exceeding 20’ of liquid, lling the chambers with liquid will prime the pump in most cases.
Undersized suction line. Meet or exceed pump connections.
Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.
Suction side air leakage or air in product. Visually inspect all suction-side gaskets and pipe connections.
Check valve obstructed. Disassemble the wet end of the pump and manually dislodge obstruction in the check valve pocket.
Check valve and/or seat is worn or needs adjusting. Inspect check valves and seats for wear and proper setting. Replace if necessary.

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 air 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.
Step 9: Complete assembly of entire unit.
One Piece Diaphragm Servicing (Bonded PTFE
with integral plate) The One Piece diaphragm has
a threaded stud installed in the integral plate at the
factory. The inner diaphragm plate has a through
hole instead of a threaded hole. Place the inner
plate over the diaphragm stud and thread the rst
diaphragm / inner plate onto the diaphragm rod only
until the inner plate contacts the rod. Do not tighten. A
small amount of grease may be applied between the
inner plate and the diaphragm to facilitate assembly.
Insert the diaphragm / rod assembly into the pump
and install the outer chamber. Turn the pump over
and thread the second diaphragm / inner plate onto
the diaphragm rod. Turn the diaphragm until the
inner plate contacts the rod and hand tighten the
assembly. Continue tightening until the bolt holes
align with the inner chamber holes. DO NOT LEAVE
THE ASSEMBLY LOOSE.
