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.

RECYCLING
Many components of SANDPIPER® AODD
pumps are made of recyclable materials.
We encourage pump users to recycle worn
out parts and pumps whenever possible,
after any hazardous pumped fluids are
thoroughly ushed.

PRINCIPLE OF PUMP OPERATION
This ap 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 spool. This pushes it into position for
shifting of the air distribution valve.
The chambers are manifolded together with a suction and discharge ap-type
check valve for each chamber, maintaining ow 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 ttings to a minimum. Do not reduce line size.
For installations of rigid piping, short exible 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 ow.
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, ll 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 sufcient capacity and pressure required for desired performance.
When the air line is solid piping, use a short length of exible 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 ow as desired. If opening the valve increases
cycling rate, but does not increase ow rate, cavitation has occurred, and the valve
should be closed slightly.
For the most efcient use of compressed air and the longest diaphragm life, throttle
the air inlet to the lowest cycling rate that does not reduce ow.
A NOTE ABOUT 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 sup-
ply would entail the use of an air line lubricator (available from Warren Rupp) set to
deliver one drop of 10 wt., non-detergent oil for every 20 SCFM of air the pump con-
sumed 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 freez-
ing 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 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.
ESADS: 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.

msa2dl5sm-REV0316 Models MSA2 MSA2-B MSA2-C Page 3
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).
Re-install one end cap, gasket and bumper on the valve body. Using the arbor press
or bench vise that was used in disassembly, carefully press the sleeve back into the
valve body, without shearing the o-rings. 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, 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 an alternating cross pattern.
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 ow and reduce pump performance .When the product source is at a higher level
than the pump (ooded suction), pipe the exhaust higher than the product source to
prevent siphoning spills. (See page 7)
Freezing or icing-up of the air exhaust can occur under certain temperature and
humidity conditions. Use of an air 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 ushed 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
Valve inspection requires removal of (4) 3/8" hex nuts. On the suction side the ange,
when removed, carries the valve and seat as an assembly. On the discharge side,
the valve and seat will stay with the diaphragm housing. Visual inspection and clean-
ing is possible. If parts are to be replaced, remove the self locking nuts and all parts
are accessible.
DIAPHRAGM SERVICING
Diaphragms can be inspected or the diaphragm assembly removed without
removing the suction and discharge anges. Remove (8) nuts around the chamber
ange, and the housing assembly will pull off. Check valves can be inspected for
proper seating at this point as well as the diaphragm. Use care to keep foreign mat-
ter from behind the diaphragm. The opposite diaphragm may be inspected by the
same procedure. If either diaphragm has to be replaced, follow closely these steps:
Pull the outer diameter of one diaphragm off the (8) capscrews. NOTE: One side
only! On the free diaphragm assembly, use a 3/8" allen wrench to turn the as-
sembly (diaphragm, plates and screw) loose from the shaft. Once the assembly
has turned, it will turn out by hand by use of the diaphragm. Now the opposite dia-
phragm assembly and the drive shaft will pull free from the capscrews and pump
intermediate assembly. The interior components consisting of sleeve bearings, rod
seals, and pilot valve actuator bushings are now accessible for service if required.
Hold the shaft in a clamping device making sure to protect surface of shaft so as not to
scratch or mar it in any way. The diaphragm assembly will turn loose. To disassemble
the components, turn a 1/4"-20 capscrew by hand into the tapped hole in the inner
plate. This keeps the plate from turning while the socket head capscrew is removed.
To do this, place assembly in a vise so the two protruding ends of screws are loose
in the vise jaws (about 3/4" apart). Turn the center screw loose from the back plate
and the assembly will come apart.

Models MSA2 MSA2-B MSA2-C Page 4 msa2dl5sm-REV0316
REASSEMBLY
All procedures for reassembling the pump are the reverse of the previous instruc-
tions with further instructions as shown:
1. The diaphragm assemblies are to be installed with the natural bulge outward or
toward the head of the center screw. Make sure both plates are installed with outer
radii against the diaphragm. After all components are in position in a vise and hand
tight, set a torque wrench for 480 inch pounds (40 ft. pounds) (54.23 Newton meters)
using a (3/8") allen head socket. After each diaphragm sub assembly has been com-
pleted, thread one assembly into the shaft (held near the middle in a vise having soft
jaws to protect the nish) making sure the stainless steel washer is in place on the
capscrew.
Make sure 1/4"-20 mounting screw has been removed and that the bumper (Item
#19 on drawing) is in place in the shaft.
Install this sub assembly into the pump and secure by placing the outer chamber
housing and capscrews on the end with the diaphragm. This will hold the assembly
in place while the opposite side is installed. Make sure the last diaphragm assembly
is torqued to 30 ft. lbs. (40.67 Newton meters) before placing the outer diaphragm
over the capscrews. If the holes in the diaphragm ange do not line up with the holes
in the chamber ange, turn the diaphragm assembly in the direction of tightening
to align the holes so that the capscrews can be inserted. This nal torquing of the
last diaphragm assembly will lock the two diaphragm assemblies together. Place
remaining outer chamber on the open end and tighten down the securing nuts gradu-
ally and evenly on both sides.
Caution should be used while reassembling check valves. The valves are designed
for some preload over the retainer hinge pad. This is done to insure proper face contact
with the seat. After all parts are in place, tighten the 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 prime. However, after priming action has started, valves will
function due to differential pressure without concern or trouble.
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 ne piece of wire to pull them out. The bushing can be turned out through the in-
ner chamber by removing the outer chamber assembly. Replace the bushings if pins
have bent.
TROUBLESHOOTING
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 seating properly.
D. Leakage at joint of suction manifold or elbow ange.
E. Suction line or strainer plugged.
F. Diaphragm ruptured.

msa2dl5sm-REV0316 Models MSA2 MSA2-B MSA2-C Page 5
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
supply 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.)
PROBLEM: Uneven discharge ow. (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 ange one side.
