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.

PRINCIPLE OF PUMP OPERATION
This flap swing check valve pump is powered by compressed air and is a 1:1
pressure ratio design. It alternately pressurizes the inner side of one diaphragm
chamber, while simultaneously exhausting the other inner chamber. This causes the
diaphragms, which are connected by a common rod, to move endwise. Air pressure
is applied over the entire surface of the diaphragm, while liquid is discharged from
the opposite side. The diaphragm operates under a balanced condition during the
discharge stroke, which allows the unit to be operated at discharge heads over
200 feet (61 meters) of water head.
Since the diaphragms are connected by a common rod, secured by plates to the
center of the diaphragms, one diaphragm performs the discharge stroke, while the
other is pulled to perform the suction stroke in the opposite chamber.
For maximum diaphragm life, keep the pump as close to the liquid being pumped
as possible. Positive suction head in excess of 10 feet of liquid (3.048 meters) may
require a back pressure regulating device. This will maximize diaphragm life.
Alternate pressuring and exhausting of the diaphragm chamber is performed
by means of an externally mounted, pilot operated, four-way spool type air
distribution valve. When the spool shifts to one end of the valve body, inlet air
pressure is applied to one diaphragm chamber and the other diaphragm chamber
exhausts. When the spool shifts to the opposite end of the valve body, the porting of
chambers is reversed. The air distribution valve spool is moved by an internal pilot
valve which alternately pressurizes one side of the air distribution valve spool, while
exhausting the other side. The pilot valve is shifted at each end of the diaphragm
stroke by the diaphragm plate coming in contact with the end of the pilot valve
spool. This pushes it into position for shifting of the air distribution valve.
The chambers are manifolded together with a suction and discharge check valve
for each chamber, maintaining flow in one direction through the pump.
INSTALLATION & START-UP
Locate the pump as close to the product being pumped as possible, keeping
suction line length and number of fittings to a minimum. Do not reduce line size.
For installations of rigid piping, short flexible sections of hose should be installed
between pump and piping. This reduces vibration and strain to the piping system.
A Warren Rupp Tranquilizer®Surge Suppressor is recommended to further reduce
pulsation in flow.
This pump was tested at the factory prior to shipment and is ready for operation.
It is completely self-priming from a dry start for suction lifts of 20 feet (6.096 meters)
or less. For suction lifts exceeding 20 feet of liquid, fill the chambers with liquid
prior to priming.
AIR SUPPLY
Air supply pressures cannot exceed 125 psi (8.61 bar). Connect the pump
air inlet to an air supply of sufficient capacity and pressure required for desired
performance. When the air line is solid piping, use a short length of flexible hose
(not less than 3/4" (19mm) in diameter) between pump and piping to eliminate
strain to pipes.
AIR INLET & PRIMING
For start-up, open an air valve approximately 1/2" to 3/4" turn. After the unit
primes, an air valve can be opened to increase flow as desired. If opening the valve
increases cycling rate, but does not increase flow rate, cavitation has occurred,
and the valve should be closed slightly.
For the most efficient use of compressed air and the longest diaphragm life,
throttle the air inlet to the lowest cycling rate that does not reduce flow.

AIR VALVE LUBRICATION
The Sandpiper pump’s pilot valve and main air valve assemblies are designed
to operate WITHOUT lubrication. This is the preferred mode of operation.
There may be instances of personal preference, or poor quality air supplies when
lubrication of the compressed air supply is required. The pump air system will
operate with properly lubricated compressed air supplies. Proper lubrication of
the compressed air supply would entail the use of an air line lubricator (available
from Warren Rupp) set to deliver one drop of 10 weight, non-detergent oil for every
20 SCFM of air the pump consumed at its point of operation. Consult the pump’s
published Performance Curve to determine this.
It is important to remember to inspect the sleeve and spool set routinely. It
should move back and forth freely. This is most important when the air supply is
lubricated. If a lubricator is used, oil accumulation will, over time, collect any debris
from the compressed air. This can prevent the pump from operating properly.
Water in the compressed air supply can create problems such as icing or
freezing of the exhaust air causing the pump to cycle erratically, or stop operating.
This can be addressed by using a point of use air dryer (available from Warren
Rupp) to supplement a plant’s air drying equipment. This device will remove excess
water from the compressed air supply and alleviate the icing or freezing problem.
Externally Serviceable Air Distribution System
Please refer to the exploded view drawing and parts list in the Service Manual
supplied with your pump. If you need replacement or additional copies, contact
your local Warren Rupp Distributor, or the Warren Rupp factory Literature
Department at the number shown below. To receive the correct manual, you must
specify the MODEL and TYPE information found on the name plate of the pump.
Models with 1" suction/discharge or larger and METAL center sections
The main air valve sleeve and spool set is located in the valve body mounted
on the pump with four hex head capscrews. The valve body assembly is removed
from the pump by removing these four hex head capscrews.
With the valve body assembly off the pump, access to the sleeve and spool set
is made by removing four hex head capscrews (each end) on the end caps of the
valve body assembly. With the end caps removed, slide the spool back and forth in
the sleeve. The spool is closely sized to the sleeve and must move freely to allow for
proper pump operation. An accumulation of oil, dirt or other contaminants from the
pump’s air supply, or from a failed diaphragm, may prevent the spool from moving
freely. This can cause the spool to stick in a position that prevents the pump from
operating. If this is the case, the sleeve and spool set should be removed from the
valve body for cleaning and further inspection.
Remove the spool from the sleeve. Using an arbor press or bench vise (with
an improvised mandrel), press the sleeve from the valve body. Take care not to
damage the sleeve. At this point, inspect the o-rings on the sleeve for nicks, tears
or abrasions. Damage of this sort could happen during assembly or servicing. A
sheared or cut o-ring can allow the pump’s compressed air supply to leak or bypass
within the air valve assembly, causing the pump to leak compressed air from the
pump air exhaust or not cycle properly. This is most noticeable at pump dead head
or high discharge pressure conditions. Replace any of these o-rings as required or
set up a routine, preventive maintenance schedule to do so on a regular basis. This
practice should include cleaning the spool and sleeve components with a safety
solvent or equivalent, inspecting for signs of wear or damage, and replacing worn
components.
To re-install the sleeve and spool set, lightly lubricate the o-rings on the sleeve
with an o-ring assembly lubricant or lightweight oil (such as 10 wt. air line lubricant).
Press the set into the valve body easily, without shearing the o-rings. Re-install
one end cap, gasket and bumper on the valve body. Using the arbor press or
bench vise that was used in disassembly, press the sleeve back into the valve
body. You may have to clean the surfaces of the valve body where the end caps
mount. Material may remain from the old gasket. Old material not cleaned from this
area may cause air leakage after reassembly. Take care that the bumper stays in
place allowing the sleeve to press in all the way. Reinstall the spool, the opposite
end cap, gasket and bumper on the valve body. After inspecting and cleaning the
gasket surfaces on the valve body and intermediate, reinstall the valve body on
the pump using new gaskets. Tighten the four hex head capscrews evenly and in

msa3dl7sm-REV0317 Models MSA3 Page 3
an alternating cross pattern.
PILOT VALVE
The pilot valve assembly is accessed by removing the main air distribution valve
body from the pump and lifting the pilot valve body out of the intermediate housing.
Most problems with the pilot valve can be corrected by replacing the o-rings.
Always grease the spool prior to inserting it into the sleeve. If the sleeve is removed
from the body, reinsertion must be at the chamfered side. Grease the o-rings to
slide the sleeve into the valve body. Securely insert the retaining ring around the
sleeve. When reinserting the pilot valve, push both plungers (located inside the
intermediate bracket) out of the path of the pilot valve spool ends to avoid damage.
PILOT VALVE ACTUATOR
Bushings for the pilot valve actuators are threaded into the intermediate bracket
from the outside. The plunger may be removed for inspection or replacement. First
remove the air distribution valve body and the pilot valve body from the pump. The
plungers can be located by looking into the intermediate. It may be necessary to
use a fine piece of wire to pull them out. The bushing can be turned out through
the inner chamber by removing the outer chamber assembly. Replace the bushings
if pins have bent.
AIR EXHAUST
If a diaphragm fails, the pumped liquid or fumes can enter the air end of the
pump, and be exhausted into the atmosphere. When pumping hazardous or toxic
materials, pipe the exhaust to an appropriate area for safe disposition.
This pump can be submerged if materials of construction are compatible with
the liquid. The air exhaust must be piped above the liquid level. Piping used for
the air exhaust must not be smaller than 1" (2.54 cm). Reducing the pipe size will
restrict air flow and reduce pump performance. When the product source is at
a higher level than the pump (flooded suction), pipe the exhaust higher than the
product source to prevent siphoning spills.
Freezing or icing-up of the air exhaust can occur under certain temperature and
humidity conditions. Use of a Warren Rupp Extractor/Dryer unit should eliminate
most icing problems.
BETWEEN USES
When used for materials that tend to settle out or transform to solid form, the
pump should be completely flushed after each use, to prevent damage. Product
remaining in the pump between uses could dry out or settle out. This could cause
problems with valves and diaphragms at re-start. In freezing temperatures, the
pump must be drained between uses in all cases.
CHECK VALVE SERVICING
For flap valve inspection or replacement, remove the flange bolts securing the
suction and discharge elbows and loosen Dresser-type couplings. The flap valves
are exposed for inspection or servicing upon removal of elbows.
DIAPHRAGM SERVICING
Diaphragms are serviced by removing the outer diaphragm chambers which are
secured with 12 bolts. After removing the outer chamber, unbolt the diaphragm
plate by removing 6 socket head capscrews (Allen wrench required). To remove
the diaphragm rod, remove the inner diaphragm plate secured by a nut on the end
of the diaphragm rod. The opposite diaphragm and rod can then be removed as
a unit. The interior components consisting of sleeve bearings, rod seals, and pilot
valve actuator bushings are now accessible for service if required.
REASSEMBLY
All procedures for reassembling the pump are the reverse of the above with
these further instructions:
1. Install the diaphragms with their natural bulge outward. Make certain that the
rubber diaphragm rod bumper is installed on the rod behind each inner diaphragm
plate. Re-torque the 6 socket head capscrews that secure the diaphragm between
the plates to 30 foot Ibs. (40.67 Newton meters) torque reading.
2. Caution should be used while reassembling the check valves. The valves
are designed for some preload over the retainer and the hinge pad. This is done
to insure proper face contact with the seat. After all parts are in place, tighten the

Model MSA3 Page 4 msa3dl7sm-REV0317
lock nuts down on the assembly to the point where visual inspection shows that
seat and valve face mate without gap. This is important for dry primes. However,
after priming action has started, valves will function due to differential pressure
without concern or trouble.
TROUBLE SHOOTING
PROBLEM: Pump cycles but will not pump. (Note: higher suction lifts require faster
cycling speed for priming.)
POSSIBLE CAUSES:
A. Air leak in suction line.
B. Excessive suction lift.
C. Check valve not closing.
D. Leakage at joint of suction manifold or elbow flange.
E. Suction line plugged.
F. Diaphragm ruptured.
PROBLEM: Pump will not cycle. (Note: Always disconnect air supply to relieve air
pressure before disassembling any portion of pump.)
POSSIBLE CAUSES:
A. Discharge hose or line plugged, or discharge head requirement greater than air
pressure. (Disconnect discharge line to check.)
B. Spool in air distribution valve not shifting. (Remove end cap and check spool
- must slide freely.)
C. Diaphragm ruptured. (Air will escape out discharge line in this case.)
D. Blockage in diaphragm chamber preventing movement. (Shut off air supply and
reopen after pressure is relieved.)
E. Plugged or dirty exhaust muffler.
PROBLEM: Uneven discharge flow. (Indicates one chamber not operating properly.)
POSSIBLE CAUSES:
A. Check valve not sealing properly in one chamber.
B. Diaphragm failure in one chamber.
C. Air leak at suction manifold joint or elbow flange one side.
