MODEL MAY NOT BE SHOWN. Always refer to the parts list and exploded view
drawing for your specific model when installing, disasembling or servicing
your pump.
PRINCIPLE OF PUMP OPERATION
This ball type check valve pump is powered by compressed air and is a 1:1 pres-
sure 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. Do not install on suction head in excess of 10 feet of liquid (3.048 meters).
Consult factory if conditions exceed this recommendation.
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 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 suc-
tion 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 pulsa-
tion in ow. Tighten all gaskets prior to start-up.
This pump was tested at the factory prior to shipment and is ready for operation.
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.

CAUTION
The air exhaust should be
piped to an area for safe
disposition of the product
being pumped, in the event
of a diaphragm failure.

hdb15dl6sm-REV0208 Models HDB1½-A, HDB40-A Page 3
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.
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.
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
For best priming and most efcient pumping performance, it is important to maintain
check valves and valve seats in good condition for proper sealing. Need for inspection
or service of ball valves is usually indicated by poor priming, unstable cycling, reduced
performance, or pump cycles but will not pump.
Inspection and service of check valves requires the removal of six bolts which
provide access to all four ball valves and both, suction and discharge, valve seats.
New ball check valves are 21/4" (5.715 cm) diameter and will require replacement when
worn to approximately 2" (5.08 cm) diameter.
DIAPHRAGM SERVICING
Need for inspection, or service, of diaphragm is usually indicated when unit pumps
from one chamber only and air is discharged out pump discharge port or when liq-
uid being pumped is discharged through air exhaust port. To service diaphragms,
remove V-Band clamp (no. 15) and two hex nuts (no. 29) which secure chamber port
to manifold. To remove diaphragms, loosen diaphragm assembly (outer plate no. 20,
diaphragm no. 21, inner plate no. 19) by turning out of the shaft using a wrench. A 1"
(2.54 cm) square lug is provided on the outer plate (no. 20) for this purpose. Removal
of opposite outer chamber will permit removal of second diaphragm assembly and
shaft as a unit. To disassemble the diaphragm assemblies, clamp the inner diaphragm
plate (no. 19) around the outer diameter between jaws of a vise to hold it while you
turn the outer diaphragm plate (no. 20) loose using a wrench. Interior components
consisting of shaft seals and sleeve bearings are now accessible for service if required.
REASSEMBLY
All procedures for reassembling the diaphragms are just in reverse of previous
instructions for disassembly. The diaphragms are to be installed with their natural
bulge outward or toward the outer diaphragm plate (no. 20). Make sure the inner plate
is installed with the at face against the diaphragm.
After all components are in position in vise and hand tight, tighten with wrench to
approximately 40 ft. lbs. (54.23 Newton meters) torque. After each diaphragm assembly
has been made, thread one assembly into shaft (no. 16) (hold shaft near middle in vise
having soft jaws to protect nish). Install this sub assembly into pump and secure by
placing the outer chamber (no. 22) on the end with the diaphragm. This will hold the

Models HDB1½-A, HDB40-A Page 4 hdb15dl6sm-REV0208
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). This nal torquing will lock
the diaphragm assemblies together. Place remaining outer chamber on open end and
secure. Snug ange bolts of chamber to port manifold to square the anges before
the nal tightening of the V-Band clamps. Tighten ange bolts securely after tightening
V-Band clamp. IMPORTANT: Do not tighten the V-Band clamp without loosen-
ing manifold flange bolts at outer chamber ports. The chamber flange may be
broken this way.
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
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 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. 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.
IMPORTANT
Do not tighten the V-Band clamp without
loosening maniford flange bolts at outer
chamber ports. The chamber flange
may be broken this way.

hdb15dl6sm-REV0208 Models HDB1½-A, HDB40-A Page 5
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. Re-install
the spool, the opposite end cap, gasket and bumper on the valve body. After inspect-
ing and cleaning the gasket surfaces on the valve body and intermediate, re-install
the valve body on the pump using new gaskets. Tighten the four hex head capscrews
evenly and in 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 (see #40 on drawing), located
inside the intermediate bracket, out of the path of the pilot valve spool ends to avoid
damage.
PILOT VALVE ACTUATOR
The bushings (no. 37) for the pilot valve actuators threaded into the intermediate
bracket (no. 17) from the outside. The plunger (no. 40) may be removed for inspection
or replacement from the inside by removing the air distribution valve body (no. 5) and
the pilot valve body (no. 34) from the pump. The plungers (no. 40) should be visible
as you look down into the intermediate from the top. Depending on their position, you
may nd it necessary to use a ne piece of wire to pull them out.
Under rare circumstances, it may become necessary to replace the o-ring seal
(no. 41). If it cannot be removed in much the same manner as the plunger (no. 40), the
bushing (no. 37) can be turned out through the inner chamber (no. 12) by removing
the manifold assembly (no. 31) and the outer chamber (no. 22) to reach the bushing
(no. 37).
