PLEASE NOTE!
The photos shown in this manual are for general instruction only. Your specific
model may not be shown. Always refer to the parts list and exploded view drawing
for your specific model when installing, disassembling or servicing your pump.
PRINCIPLE OF PUMP OPERATION
This ball 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 oppo-
site side. The diaphragm operates under a balanced condition during the dis-
charge 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) is not
recommended. For applications with higher suction heads, consult the factory.
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. Tighten all fasteners before pump startup.
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 10-15 feet (9-14
meters) or less. For suction lifts exceeding 15 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 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 an air dryer 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
Need for inspection or service is usually indicated by poor priming, unstable
cycling, reduced performance or the pump’s cycling but not pumping.
Remove the six flange bolts securing the inlet and outlet flanges to the manifold.
Inspect the surfaces of both check valve and seat for wear or damage that could
prevent proper sealing. If pump is to prime properly, valves must seat air tight.
DIAPHRAGM SERVICING
Remove the four bolts securing the manifold flange to the chamber. Remove the
eight nuts securing the outer diaphragm chamber flange and remove the chamber.
Loosen the capscrew securing the diaphragm and plate to the rod by leaving the
diaphragm engaged with the capscrews around the outer flange, preventing rotation
of the rod. DO NOT USE A WRENCH ON THE DIAPHRAGM ROD. FLAWS ON THE
SURFACE MAY DAMAGE BEARINGS AND SEAL.
During reassembly make certain that the rubber bumper is on the rod on each
side. Install the diaphragm with the natural bulge outward as indicated on the
diaphragm. Install the heavier plate on the outside of the diaphragm and make
certain that the large radius side of both plates are toward the diaphragm. Place the
sealing washer between the inner diaphragm plate and the end of the rod. Tighten
the capscrew to approximately 25 ft. lbs. (33.9 Newton meters). Torque while allowing
diaphragm to turn freely with plates. Except for EPDM Rubber, use a lightweight oil
between plates and diaphragm when doing this procedure. Use a wrench on the
capscrew of the opposite side to keep the rod from rotating. If the opposite chamber
is assembled, the rod need not be held.
When reassembling the outer chambers and the manifold, the bolts securing the
manifold flange to the chamber should be snugged prior to tightening the chamber
bolts, to insure that the chamber port flange is square with the manifold flange. Finish
tightening the manifold flange bolts after chamber bolting is secured.
AIR VALVE LUBRICATION
The SandPlPER 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.

520-146-000 7/03 Models SB1-A & SB25A Page 3
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. 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.
To receive the correct manual, you must specify the MODEL and TYPE information
found on the name plate of the pump.
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 a retaining ring (each end) securing the end cap on 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 abra-
sions. 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 equiva-
lent, 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).
Re-install one end cap, and retaining ring (see safety warning), 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. Re-install the
spool, opposite end cap and retaining ring (see safety warning), 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, at 150 in./lbs.
(16.94 Newton meters).
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 held in the inner chambers with retaining
rings. An o-ring is behind each bushing. If the plunger has any sideways motion,
check o-rings and bushing for deterioration or wear. The plunger may be removed for
SAFETY WARNING
To assure proper pump function
and safe installation of the retain-
ing ring, check the gap “G”
dimension for full installation into
the valve body grooves.

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.
SERVICE INSTRUCTIONS: TROUBLE SHOOTING
1. Pump will not cycle
A. Check to make sure the unit has enough pressure to operate and that the air inlet
valve is open.
B. Check the discharge line to insure that the discharge line is neither closed nor
blocked.
C. It the spool in the air distribution valve is not shifting, check the main spool. It must
slide freely.
D. Excessive air leakage in the pump can prevent cycling. This condition will be
evident. Air leakage into the discharge line indicates a ruptured diaphragm. Air
leakage from the exhaust port indicates leakage in the air distribution valve. See
further service instructions.
E. Blockage in the liquid chamber can impede movement of diaphragm.
2. Pump cycles but will not pump
A. Suction side of pump pulling in air. Check the suction line for air leaks and be sure
that the end of the suction line is submerged. Check flange bolting. Check valve
flanges and manifold to chamber flange joints.
B. Make certain the suction line or strainer is not plugged. Restriction at the suction
is indicated by a high vacuum reading when a vacuum gauge is installed in the
suction line.
C. Check valves may not be seating properly. To check, remove the suction line and
cover the suction port with your hand. If the unit does not pull a good suction
(vacuum), the check valves should be inspected for proper seating.
D. Static suction lift may be too high. Priming can be improved by elevating the
suction and discharge lines higher than the check valves and pouring liquid into
the unit through the suction inlet. When priming at high suction lifts or with long
suction lines operate the pump at maximum cycle rate.
3. Low performance
A. Capacity is reduced as the discharge pressure increases, as indicated on the
performance curve. Performance capability varies with available inlet air supply.
Check air pressure at the pump inlet when the pump is operating to make certain
that adequate air supply is maintained.
B. Check vacuum at the pump suction. Capacity is reduced as vacuum increases.
Reduced flow rate due to starved suction will be evident when cycle rate can be
varied without change in capacity. This condition will be more prevalent when
pumping viscous liquids. When pumping thick, heavy materials the suction line
must be kept as large in diameter and as short as possible, to keep suction loss
minimal.
C. Low flow rate and slow cycling rate indicate restricted flow through the discharge
line. Low flow rate and fast cycling rate indicate restriction in the suction line or air
leakage into suction.
D. Unstable cycling indicates improper check valve seating on one chamber. This
condition is confirmed when unstable cycling repeats consistently on alternate
exhausts. Cycling that is not consistently unstable may indicate partial exhaust
restriction due to freezing and thawing of exhaust air. Use of an air dryer should
solve this problem.
For additional information, see the Warren Rupp Troubleshooting Guide.
WARRANTY
This pump is warranted for a period of five years against defective material and
workmanship. Failure to comply with the recommendations stated in this manual
voids all factory warranty.
IMPORTANT
This pump is pressurized internally with
air pressure during operation. Always
make certain that all bolting is in good
condition and that all of the correct
bolting is reinstalled during assembly.
CAUTION
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 which
is hazardous or toxic, the air exhaust
must be piped to an appropriate area for
safe disposition.
CAUTION
Before maintenance or repair, shut off
the compressed air line, bleed the
pressure, and disconnect the air line
from the pump. The discharge line may
be pressurized and must be bled of its
pressure. When used for toxic or
aggressive fluids, the pump should
always be flushed clean prior to
disassembly.

Repair Parts shown in bold face (darker)
type are more likely to need replacement
after extended periods of normal use. They
are readily available from most Warren
Rupp distributors. The pump owner may
prefer to maintain a limited inventory of
these parts in his own stock to reduce
repair downtime to a minimum.
IMPORTANT: When ordering repair parts
always furnish pump model number, serial
number and type number.
