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.
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.
Safety Information
ATEX Pumps - Conditions For Safe Use
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.

kg
WARNING
The use of non-OEM replacement parts will void (or negate)
agency certications, including CE, ATEX, CSA, 3A and EC1935
compliance (Food Contact Materials). Warren Rupp, Inc. cannot
ensure nor warrant non-OEM parts to meet the stringent
requirements of the certifying agencies.
1. Ambient temperature range is as speci ed in tables 1 to 3 on the next page (per Annex I of DEKRA 18ATEX0094X)
2. ATEX compliant pumps are suitable for use in explosive atmospheres when the equipment is properly grounded in
accordance with local electrical codes
3. Non-Metallic ATEX Pumps only — See Explanation of Pump Nomenclature / ATEX Details Page
Conductive Polypropylene, conductive Acetal or conductive PVDF pumps are not to be installed in applications where the
pumps may be subjected to oil, greases and hydraulic liquids.
4. The optionally provided solenoids shall be protected by a fuse corresponding to its rated current (max 3*Irat according
to EN 60127) or by a motor protecting switch with short circuit and thermal instantaneous tripping (set to the rated
current) as short circuit protection. For solenoids with a very low rated current, a fuse with the lowest current value
according to the indicated standard will be suffi cient. The fuse may be accommodated in the associated supply unit
or shall be separately arranged. The rated voltage of the fuse shall be equal or greater than the stated rated voltage of the
solenoid. The breaking capacity of the fuse shall be as high as or higher than the maximum expected short circuit current
at the location of the installation (usually 1500 A). The maximum permissible ripple is 20% for all dc solenoids.
*Not applicable for all pump models — See Explanation of Pump Nomenclature / ATEX Details Page
5. When operating pumps equipped with non-conductive diaphragms that exceed the maximum permissible projected area,
as de ned in EN ISO 80079-36 : 2016 section 6.7.5 table 8, the following protection methods must be applied
- Equipment is always used to transfer electrically conductive fl uids or
- Explosive environment is prevented from entering the internal portions of the pump, i.e. dry running.
6. Pumps provided with the pulse output kit and used in the potentially explosive atmosphere caused by the presence of
the combustible dust shall be installed in such a way that the pulse output kit is protected against impact

Principle of Pump Operation
Air Line
Discharged
Fluid
Discharge
Stroke Suction
Stroke
Primed
Fluid
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.
This Containment Duty SANDPlPER unit differs from other SANDPIPER units only in that it utilizes four
(4) diaphragms instead of two (2). Two rod-connected diaphragms are the driver diaphragms. The other
two (outermost) diaphragms are the actual pumping diaphragms. Each driver diaphragm (of neoprene
or other elastomer), and the pumping diaphragm (of PTFE), are separated by a chamber lled with liquid
which transmits the reciprocating motion of the driver diaphragm to the pumping diaphragm. The PTFE
pumping diaphragms, in turn, create the alternating suction and discharge action in the outer diaphragm
chambers, and are the only diaphragms in contact with liquid being pumped.

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.

If you prefer to substitute another liquid, to prevent
system contamination consult the factory rst to
determine compatibility of the substitute with pump
construction.
Follow the steps listed below to replace the liquid
in the pump after disassembly or liquid loss:
Step 1. Disconnect air supply from pump before
starting any work. Remove the ll and drain
plugs (¼ NPT) (.0635 cm) from the driver chambers.
After the chambers are completely drained of all
liquid, replace the drain plugs and tighten them
securely. NOTE: Use thread sealant on plug threads.
 . Remove the two large (1 NPT) (2.54
cm) pipe plugs (one on each side) located in
the rear of the innermost air chambers.
Step 3. Determine which side of the pump is on the
discharge stroke and which side is on the suction
stroke by checking the positions of the diaphragm
assemblies. The cast inner diaphragm plate closest
to the pump intermediate housing, or centerline,
is the chamber in the suction stroke position. The
opposite chamber, with cast inner diaphragm plate
away from unit centerline, is in the discharge stroke
position. NOTE: The diaphragm assemblies (cast
inner diaphragm plates) are visible through the two
tapped holes in the inner chambers from which the
two large pipe plugs were removed.
Step 4. For pumps with air valve assemblies
031.098.010 or 031.098.156
Insert the safety clip (210-008-330) on one side
of the main air valve body and cycle the pump at 5
to 10 psi. As you face the pump, the side with the pin
should be the rst driver uid reservoir to be lled.
The driver diaphragm will be on a suction
stroke. Pour the correct amount of liquid into the
reservoir. The uid level will not come completely to
the top. Loosely install the pipe plug, with pipe dope,
PTFE tape or o-ring (depending on pump model)
placed on the threads. Release all air pressure to the
pump and remove the safety clip. The diaphragm will
relax and will come to center. Watch the loose pipe
plug closely as air escapes and the driver uid level
rises. Insert the safety clip on the opposite side and
add a small amount of air pressure. When you see
liquid weeping out between the loose pipe plug and
ll hole, tighten the pipe plug. Repeat the procedure
for the unlled chamber.
If you have a problem getting the driver uid to come
to the top, a blunt instrument can be inserted into the
chamber port of the pump and pressure can manually
be applied to the pumping diaphragm to cause the
liquid to come to the top. Do this carefully. A needle
valve for precision stroking control is recommended
at the air inlet for this procedure. Please be aware that
air left in the chambers will result in faulty operation of
the pump and will cause premature pumping
diaphragm failure.
For pumps not equipped with Visual Leak Detection
sight tubes, ll with 1200ml/ 40.6 . oz.
For pumps equipped with Visual Leak Detection sight
tubes, ll with 1250ml/ 42.3 . oz.
Use pipe sealant on pipe plugs. Cast iron fluid
chambers typically lled with normal antifreeze.
Step 5. After lling, the liquid will not come all the
way to the top of the lling hole. Use a screwdriver or
similar tool to apply leverage on the inner diaphragm
plate (diaphragm assembly) forcing the driver
diaphragm on the side you have just lled partially
through its discharge stroke until the liquid level in the
chamber you are lling comes to the top of the ll hole.
This displaces any air in the chamber. CAUTION: Do
not pry on or damage the elastomer diaphragm while
performing this step of the lling instructions.
Step 6. Re-plug the ll hole and tighten securely.
NOTE: Use thread sealant on plug threads and tighten
only until snug.
Step 7. Using a screwdriver or similar tool apply

Pump Cycles Once Deadhead (system pressure meets or exceeds air
supply pressure).
Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero ow.
(Does not apply to high pressure 2:1 units).
Air valve or intermediate gaskets installed incorrectly. Install gaskets with holes properly aligned.
Bent or missing actuator plunger. Remove pilot valve and inspect actuator plungers.
Pump Will Not Operate
/ Cycle
Pump is over lubricated. Set lubricator on lowest possible setting or remove. Units are designed for lube free operation.
Lack of air (line size, PSI, CFM). Check the air line size and length, compressor capacity (HP vs. cfm required).
Check air distribution system. Disassemble and inspect main air distribution valve, pilot valve and pilot valve actuators.
Discharge line is blocked or clogged manifolds. Check for inadvertently closed discharge line valves. Clean discharge manifolds/piping.
Deadhead (system pressure meets or exceeds air
supply pressure).
Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero ow.
(Does not apply to high pressure 2:1 units).
Blocked air exhaust mufer. Remove mufer screen, clean or de-ice, and re-install.
Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.
Pump chamber is blocked. Disassemble and inspect wetted chambers. Remove or ush any obstructions.
Pump Cycles and Will
Not Prime or No Flow
Cavitation on suction side. Check suction condition (move pump closer to product).
Check valve obstructed. Valve ball(s) not seating
properly or sticking.
Disassemble the wet end of the pump and manually dislodge obstruction in the check valve pocket.
Clean out around valve ball cage and valve seat area. Replace valve ball or valve seat if damaged.
Use heavier valve ball material.
Valve ball(s) missing (pushed into chamber or
manifold).
Worn valve ball or valve seat. Worn ngers in valve ball cage (replace part). Check Chemical
Resistance Guide for compatibility.
Valve ball(s) / seat(s) damaged or attacked by product. Check Chemical Resistance Guide for compatibility.
Check valve and/or seat is worn or needs adjusting. Inspect check valves and seats for wear and proper setting. Replace if necessary.
Suction line is blocked. Remove or ush obstruction. Check and clear all suction screens or strainers.
Excessive suction lift. For lifts exceeding 20’ of liquid, lling the chambers with liquid will prime the pump in most cases.
Suction side air leakage or air in product. Visually inspect all suction-side gaskets and pipe connections.
Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.
Pump Cycles Running
Sluggish / Stalling,
Flow Unsatisfactory
Over lubrication. Set lubricator on lowest possible setting or remove. Units are designed for lube free operation.
Icing. Remove mufer screen, de-ice, and re-install. Install a point of use air drier.
Clogged manifolds. Clean manifolds to allow proper air ow.
Deadhead (system pressure meets or exceeds air
supply pressure).
Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero ow.
(Does not apply to high pressure 2:1 units).
Cavitation on suction side. Check suction (move pump closer to product).
Lack of air (line size, PSI, CFM). Check the air line size, length, compressor capacity.
Excessive suction lift. For lifts exceeding 20’ of liquid, lling the chambers with liquid will prime the pump in most cases.
Air supply pressure or volume exceeds system hd. Decrease inlet air (press. and vol.) to the pump. Pump is cavitating the uid by fast cycling.
Undersized suction line. Meet or exceed pump connections.
Restrictive or undersized air line. Install a larger air line and connection.
Suction side air leakage or air in product. Visually inspect all suction-side gaskets and pipe connections.
Suction line is blocked. Remove or ush obstruction. Check and clear all suction screens or strainers.
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.
Entrained air or vapor lock in chamber(s). Purge chambers through tapped chamber vent plugs.
