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
spoolshifts to the opposite end of the valvebody,theporting of chambers is reversed.
The air distribution valve spool is moved by an internal pilot valve which alternately
pressurizesonesideoftheairdistributionvalvespool,whileexhaustingtheotherside.
The pilot valve is shifted at each end of the diaphragm stroke by the diaphragm plate
comingin contact with theendof the pilot spool.Thispushesit into position forshifting
of the air distribution valve.
The chambers are manifolded together with a suction and discharge flap-type
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
Forstart-up,openan airvalveapproximately 1/2"to3/4" turn.Afterthe unitprimes,
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.
Forthemostefficientuseofcompressedairandthelongestdiaphragmlife,throttle
the air inlet to the lowest cycling rate that does not reduce flow.
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 supply
wouldentailtheuseofanairlinelubricator(availablefromWarrenRupp)set todeliver
one drop of 10 wt., 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 to supplement a plant’s air drying
equipment.Thisdevice 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
thenumbershownbelow.Toreceivethecorrectmanual,youmustspecifytheMODEL
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.Thespooliscloselysizedtothesleeveandmustmovefreelytoallowforproper
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
cancause the spool to stick ina position that prevents the pumpfrom 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
thesleeve. At this point, inspect the o-rings onthesleevefor 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
includecleaning the spool and sleeve components with asafetysolventor equivalent,
inspecting for signs of wear or damage, and replacing worn components.
WARNING
Take action to prevent static sparking.
Fireor explosion canresult, especially
when handling flammable liquids. The
pump,piping,valves,containersorother
miscellaneous equipment must be
grounded. (See page 6)
BEFORE OPERATION
Before pump operation, inspect all
gasketedfastenersforloosenesscaused
by gasket creep. Retorque loose
fasteners to prevent leakage. Follow
recommendedtorquesstatedinthecard
attached to the new pump.
DANGER
Before doing any maintenance on the
pump, be certain all pressure is
completely vented from the pump,
suction,discharge,piping,andallother
openings and connections. Be certain
the air supply is locked out or made
non-operational, so that it cannot
be started while work is being done
on the pump. Be certain that approved
eye protection and protective clothing
are worn at all times in the vicinity
of the pump. Failure to follow
these recommendations may result
in serious injury or death.

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
materialnotcleanedfromthisareamaycauseairleakageafterreassembly.Takecare
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
flowandreducepumpperformance.When the product source is at a higher level than
thepump(floodedsuction),pipetheexhausthigherthantheproductsourcetoprevent
siphoning spills.
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
Whenusedformaterialsthattendto 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
valvesanddiaphragmsatre-start.Infreezingtemperatures,thepumpmustbedrained
between uses in all cases.
CHECK VALVE SERVICING
Valveinspectionrequiresremovalof(4)3/8"hexnuts.Onthesuctionsidetheflange,
whenremoved, carries the valve and seat as anassembly. On the discharge side, the
valve and seat will stay with the diaphragm housing. Visual inspection and cleaning
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 flanges. Remove (8) nuts around the chamber
flange, 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 matter
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:
Pullthe 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 assembly
(diaphragm, plates and screw) loose from the shaft. Once the assembly has turned,
itwillturnoutbyhandbyuseofthediaphragm.Nowtheoppositediaphragmassembly
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

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
inthevise jaws(about3/4"apart).Turn thecenterscrewloosefrom thebackplateand
the assembly will come apart.

REASSEMBLY
All procedures for reassembling the pump are the reverse of the previous
instructions 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
completed, thread one assembly into the shaft (held near the middle in a vise having
softjaws to protect the finish) making sure the stainless steel washer is inplaceonthe
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
istorquedto30ft.lbs.(40.67Newtonmeters)beforeplacing theouterdiaphragmover
the capscrews. If the holes in the diaphragm flange do not line up with the holes in the
chamber flange, turn the diaphragm assembly in the direction of tightening to align
the holes so that the capscrews can be inserted. This final 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
gradually 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
theassemblytothe pointwhere visualinspectionshows thatseat andvalve facemate
withoutgap. 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 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.
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 flange.
E. Suction line or strainer plugged.
F. Diaphragm ruptured.
IMPORTANT
Before pump operation, all external
gasketed fasteners must be inspected
for looseness caused by gasket creep
afterleavingthefactory.Retorqueloose
fasteners to insure against leakage.
Follow recommended torques where
called out. (A card is attached to each
new pump stating this fact.)
Thispumpispressurizedinternallywith

520-010-000 5/03 Model SA2-A 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 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.
