Heavy Duty Flap Valve
PRINCIPLE OF PUMP OPERATION
This ap swing 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
valve for each chamber, maintaining ow in one direction through the pump
Type 6
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
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 sufcient 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 efcient 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
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.

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).
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

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.
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.
FLAP VALVE SERVICING
Valve inspection requires removal of 3/8" hex nuts and elbows. When the top suction elbows are removed, the valve and
seat are connected as an assembly. When the bottom discharge elbows are removed, the valve and seat stay with the outer
chamber. 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 anges.
Remove (8) nuts around the chamber ange, and the housing assembly will pull off. Flap 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:
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 assembly (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 diaphragm 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.
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) or, 600 inch pounds (50 ft. pounds)
(67.79 Newton meters) for Santoprene, 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 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
gradually and evenly on both sides.
Caution should be used while reassembling Flap 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 as-
hdf2dl6sm-rev0614 Model HDF2 Page 8
sembly 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
inner chamber by removing the outer chamber assembly. Replace the bushings if pins
have bent.
WARRANTY:
This unit is guaranteed for a period of ve years against defective material and workmanship.
TROUBLESHOOTING - For additional information, see the Warren Rupp Troubleshooting Guide.
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. Flap valve not seating properly.
D. Leakage at joint of suction manifold or elbow ange.
E. Suction line or strainer 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 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. Flap 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.
For additional information, see the Warren Rupp Troubleshooting Guide.
