hydrocarbons and chlorinated aromatic hydrocarbons.

PTFE Chemically inert, virtually impervious. Very few chemicals are known to react chemically with

PTFE: molten alkali metals, turbulent liquid or gaseous uorine and a few uoro-chemicals such as
chlorine triuoride or oxygen diuoride which readily liberate free uorine at elevated temperatures.

FKM (Fluorocarbon) shows good resistance to a wide range of oils and solvents; especially all aliphatic,
aromatic and halogenated hydrocarbons, acids, animal and vegetable oils. Hot water or hot aqueous solu
tions (over 70°F) will attack FKM.

PRINCIPLE OF OPERATION

All Warren Rupp SANDPlPER pumps, including this Containment Duty SANDPlPER
pump, operate on the same basic principle. They are designed to be powered by compressed
air only which alternately pressurizes the inner side of one diaphragm chamber while
simultaneously exhausting the other inner chamber. The diaphragms are connected by
a common rod; when the inner side of one diaphragm chamber is pressurized, moving
the diaphragm outward on a discharge stroke, the opposite diaphragm is pulled inward
on a suction stroke.

Alternate pressurizing and exhausting of the diaphragm chamber is accomplished
with an externally mounted pilot operated, four way, spool type, air distribution valve.
When the spool is at one end of the valve body, inlet air pressure is connected to one
diaphragm chamber while the other diaphragm chamber is exhausting. When the spool
is moved to the opposite end of the valve body, the porting of chambers is reversed. The
air distribution valve spool is moved from one end position to the other in the valve body
by an internal pilot valve which alternately pressurizes one end of the air distribution valve
spool while simultaneously exhausting the other. The pilot valve is positively shifted at
each end of the diaphragm stroke by the diaphragm plate contacting the end of the pilot
valve spool. This pushes it into position to shift the air distribution valve.

In all SANDPlPER pumps, this reciprocating diaphragm movement creates an alternating
suction and discharge action in the outer diaphragm chamber and the pumped material. A
manifold with a suction and discharge check valve for each chamber serves as a common
inlet and outlet for the pump.

This Containment Duty SANDPlPER unit differs from other SANDPIPER units only in
that it utilizes four (4) diaphragms instead of two (2). Two rod-connected diaphragms are
the driver diaphragms. The other two (outermost) diaphragms are the actual pumping
diaphragms. Each driver diaphragm (of neoprene or other elastomer), and the pumping

diaphragm (of PTFE), are separated by a chamber lled with liquid which transmits the

reciprocating motion of the driver diaphragm to the pumping diaphragm. The PTFE pumping
diaphragms, in turn, create the alternating suction and discharge action in the outer

diaphragm chambers, and are the only diaphragms in contact with liquid being pumped.

Model ST40 Type 4

Original Instructions

INSTALLATION PROCEDURES

CAUTION: This pump should not be applied in pumping applications where the driver

liquid coming in contact with the pumped liquid would create a hazardous condition.
This contact will occur if a PTFE pumping diaphragm fails since this diaphragm normally
separates the two liquids. Also note that care must be taken to guard against the operation
of this unit if it has been subjected to freezing temperatures. If the driver liquid freezes,
possible diaphragm failure may result.

Locate pump as close to product to be pumped as is practical to keep length of suction

line and number of ttings to a minimum. DO NOT REDUCE SUCTION LINE SIZE except
for very low ow rates or where higher velocities are required to keep pumped material

in suspension in the carrying liquid.

This unit is completely self-priming from a dry start up to a static suction lift of 10

feet (3.05 meters). For priming at suction lifts in excess of 10 feet (3.05 meters), ll the

pumping chambers with liquid prior to operation. POSITIVE SUCTION HEAD IN EXCESS
OF 10 FEET (3.05 METERS) OF LIQUID SHOULD ALSO BE AVOIDED FOR BEST
DIAPHRAGM SERVICE LIFE.

For installations involving the use of rigid piping, short exible sections of hose are

recommended between the pump and piping. This will reduce piping strains and
vibration.

FILLING THE DRIVER CHAMBERS WITH LIQUID

THE DRIVER CHAMBERS WILL BE FILLED WITH DISTILLED WATER AT THE
FACTORY. IF THE INNER CHAMBER IS CAST IRON, THE UNIT IS FILLED WITH
ETHYLENE GLYCOL.

If you prefer to substitute another liquid, to prevent system contamination consult the

factory rst to determine compatibility of the substitute with pump construction.

Follow the steps listed below to replace the liquid in the pump after disassembly or
liquid loss:

1. Disconnect air supply from pump before starting any work. Remove the ll and drain

plugs (¼ NPT) (.0635 cm) from the driver chambers. After the chambers are completely
drained of all liquid, replace the drain plugs and tighten them securely. NOTE: Use thread
sealant on plug threads.

2. Remove the two large (1 NPT) (2.54 cm) pipe plugs (one on each side) located in

the rear of the innermost air chambers.

3. Determine which side of the pump is on the discharge stroke and which side is on
the suction stroke by checking the positions of the diaphragm assemblies. The cast inner
diaphragm plate closest to the pump intermediate housing, or centerline, is the chamber
in the suction stroke position. The opposite chamber, with cast inner diaphragm plate
away from unit centerline, is in the discharge stroke position. NOTE: The diaphragm
assemblies (cast inner diaphragm plates) are visible through the two tapped holes in
the inner chambers from which the two large pipe plugs were removed.

4. Fill the driver chamber on the suction side of the pump with 1.20 liters or 40 to 41

uid oz. by volume accuracy to 1 oz. (28.41 ml) with the driver liquid chosen for use.
The driver liquid chambers must be lled with the correct amount of the driver liquid as

too little or too much liquid can cause premature diaphragm failure and erratic pumping.

5. After lling, the liquid will not come all the way to the top of the lling hole. Use a

screwdriver or similar tool to apply leverage on the inner diaphragm plate (diaphragm

assembly) forcing the driver diaphragm on the side you have just lled partially through
its discharge stroke until the liquid level in the chamber you are lling comes to the top of
the ll hole. This displaces any air in the chamber. CAUTION: Do not pry on or damage
the elastomer diaphragm while performing this step of the lling instructions.

6. Re-plug the ll hole and tighten securely. NOTE: Use thread sealant on plug threads

and tighten only until snug.

7. Using a screwdriver or similar tool apply leverage on the inner diaphragm plate

(diaphragm assembly), on the side just lled, forcing the pump to “shift” or reverse

diaphragm positions.

8. Follow steps (4) thru (6) to ll the opposite driver chamber.

9. Re-install the two large pipe plugs in the rear of the pump inner air chambers.
NOTE: Use thread sealant on plug threads.

Revised Filling Procedure:

For pumps with air valve 031-098-000

Insert the safety clip (210-008-330, item 61) on one side of the main air valve body

and cycle the pump at 5 to 10 psi. As you face the pump, the side with the pin should

be the rst driver uid reservoir to be lled. The driver diaphragm will be on a suction
stroke. Pour the correct amount of liquid into the reservoir. The uid level will not come

completely to the top. Loosely install the pipe plug, with pipe dope, PTFE tape or o-ring
(depending on pump model) placed on the threads. Release all air pressure to the pump
and remove the safety clip. The diaphragm will relax and will come to center. Watch the

loose pipe plug closely as air escapes and the driver uid level rises. Insert the safety

clip on the opposite side and add a small amount of air pressure. When you see liquid

weeping out between the loose pipe plug and ll hole, tighten the pipe plug. Repeat the
procedure for the unlled chamber.

If you have a problem getting the driver uid to come to the top, a blunt instrument

can be inserted into the chamber port of the pump and pressure can manually be applied
to the pumping diaphragm to cause the liquid to come to the top. Do this carefully.
A needle valve for precision stroking control is recommended at the air inlet for this
procedure. Please be aware that air left in the chambers will result in faulty operation of
the pump and will cause premature pumping diaphragm failure.

st15dl4sm-rev0614 Models ST1½, ST40 Page 6

ST1½-A volume for non-overlay = 1200ml / 40.6 . oz.
Use pipe dope on pipe plugs. Cast iron uid chambers typically lled with normal

antifreeze.

CHAMBER PORTING

This unit is equipped with ball check valves and is furnished with side chamber porting
as standard. This arrangement is suitable for most pumping applications. A conversion
kit of elbows is available for optional top or bottom porting when required. Top porting is

recommended for operation at extremely low ow rates and high discharge pressures,

to eliminate accumulated air or vapor from the pumping chamber.

AIR SUPPLY

DO NOT CONNECT unit to air supply in excess of 125 PSI (8.61 Bars). Install a shutoff
valve in the air supply line to permit removal of the unit for servicing. When connecting the

unit to an air supply of rigid piping, use a section of exible line to the pump to eliminate

piping strain.

OPERATION

This pump has been tested prior to shipment and is ready for use as received.

Make certain that the capacity at which the pump is operating is not limited by
the suction conditions involved (see installation procedures). Keep in mind that the

diaphragms will move at a rate proportional to inlet air ow. If the cycling rate is allowed

to exceed the rate that liquid can enter the chamber that is on the suction stroke the liquid
is simply pulled apart (cavitation) and the pump’s displacement is reduced. For the most

efcient use of compressed air and longest diaphragm service life, always throttle the air
inlet to the lowest cycling rate that does not decrease the ow rate.

Start the unit by opening the air inlet valve approximately ½ to ¾ turn. After the unit
starts pumping the air inlet valve can be opened to increase the pumping capacity as
desired. When further opening of the valve increases the cycling rate without an increase

in capacity, cavitation exists; and the valve should be closed slightly.

FREEZING OR ICING OF EXHAUST

Icing of air exhaust can occur under certain conditions of temperature and humidity
on all compressed air powered equipment. When performance loss due to icing is
experienced, use of an air dryer should eliminate this condition. Icing will be more

prevalent at high discharge pressures.

AIR EXHAUST

SANDPlPER pumps can be submerged if the materials of construction are compatible
with the liquid and the exhaust is piped above the liquid level. Piping used for the exhaust

should not be smaller than 1" (2.54 cm) pipe size. Reduced pipe size can restrict the

exhausted air and cause reduced pump performance.

When the product being pumped is at a level above the pump (ooded suction), the

exhaust should be piped to a higher level than the product in order to prevent spillage
caused by siphoning.

MAINTENANCE AFTER USE

When this pump is used to handle materials that settle out or transform from a liquid
to a solid form, care must be taken after each use and during idle periods to remove or

ush these materials from the pump as required. Failure to do this could result in possible

premature diaphragm failure.

To drain liquid from the pump, turn the unit over on the manifold side. This position
puts the chamber ports down and will allow the check balls to fall away from the seats
allowing complete draining of the unit. This procedure is important to ensure complete
draining in freezing weather. NOTE: See note concerning operation of unit in freezing

conditions in “Installation Procedures”.

On permanent installations the pump chambers can be drained by removing the drain
plug in each outer chamber.

MAINTENANCE NOTE

A preventative maintenance procedure should be established to check the PTFE
pumping diaphragms for wear. Even though this part was proven to be good for millions
of cycles, the service life will vary with each application depending on the abrasive nature
of the liquid being pumped.

The choice of the PTFE unit indicates that the material being handled is not compatible
with the standard materials of construction (Neoprene and aluminum). If a pumping
diaphragm (PTFE) were to fail, the unit would continue pumping via the driver diaphragm.
The elastomeric driver diaphragm would then be exposed to the liquid and failure of this
diaphragm due to attack would be the end result. At this point additional damage can

occur to the air valving portion of the pump and other internal parts and castings.

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 provides
access to all four ball valves and both, suction and discharge, valve seats. New ball

check valves are 2¼" (5.715 cm) diameter and will require replacement when worn to
approximately 2" (5.08 cm) diameter.

DIAPHRAGM SERVICING

DRIVER DIAPHRAGMS

Drain the driver liquid from the driver chamber on the side to be serviced. This is
accomplished by removing the drain plug in the bottom of the driver chamber. Remove the

four (4) ange nuts that secure the manifold assembly to the pump chambers. Remove

the manifold assembly from the pump. Remove the eight (8) hex nuts that secure the
inner pumping diaphragm chamber assembly to the driver inner diaphragm chamber and
remove the assembly by pulling axially off the studs. This will permit a quick inspection of
the PTFE pumping diaphragm as well as the driver diaphragm. It is not required that the
pumping diaphragm chambers be separated to get to the driver diaphragms.

To remove the driver diaphragm, loosen the diaphragm assembly by turning it out of
the shaft using a
turned out by hand by use of the diaphragm. Removal of the opposite pumping chamber
assembly will allow removal of the second driver diaphragm assembly and the shaft as
a unit. The interior components consisting of the shaft seals and sleeve bearing are now
accessible for inspection or service as required.

To disassemble the driver diaphragm assemblies, clamp the inner diaphragm plate
around the outer diameter in a vise to hold it while you turn the center screw loose from
the back plate and the assembly will come apart.

To remove the shaft from a diaphragm assembly, hold the shaft in a clamping device
making sure to protect the shaft surface so as not to scratch or mar it in any way. Then
the diaphragm assembly will turn loose using an Allen wrench
center screw.

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. Make sure that the inner diaphragm plate

is installed with the at face against the diaphragm.

After all the components are in position in a vise and hand tightened, tighten with a
wrench to approximately 45 Ft./Lbs. (61.01 Newton meters) torque reading. After each
driver diaphragm assembly has been made thread one assembly into the shaft. Install this
subassembly into the pump and secure it by placing the pumping chamber assembly over
it and secure it in place with the eight (8) hex nuts. This will hold the diaphragm assembly
in place while the opposite side is installed. Make sure the last diaphragm assembly is

torqued into the shaft at 30 Ft./Lbs. (40.67 Newton meters). This nal torquing will lock

the diaphragm assemblies together. Place the remaining pumping chamber assembly on
the open end and secure it by tightening the nuts gradually and evenly.

PUMPING DIAPHRAGMS

It is recommended that the above procedure be followed to the point of removing the
pumping chamber assembly from the unit. Remove the hex nuts and capscrews that
secure the assembly together and lift off the outer chamber from the assembly. This
exposes the PTFE pumping diaphragm and allows access to the o-ring seal behind it.

The re-assembly is just in reverse of the above as follows: Install the o-ring seal in the
groove provided on the inner chamber. Replace the PTFE diaphragm and place the outer
chamber on the assembly making sure that the chambers inlet-outlet port centerline is

perpendicular to the centerline formed by the ll and drain plugs in the inner chamber.

Replace all fasteners that secure the assembly together and torque them at 33 Ft./Lbs.

(44.74 Newton meters) alternating from one side to the other in the process. Do not

overtighten these bolts due to the nature of PTFE to cold ow.

Reinstall the pumping chamber assembly on the pump as it was removed and ll with

the driver liquid as called out in this text. After complete re-assembly the unit should be
tested prior to installation on the job simply to make sure the capscrews and hex nuts
are torqued down properly to ensure no leakage around the PTFE diaphragm surfaces.

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 in formation

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.

st15dl4sm-rev0614 Models ST1½, ST40 Page 9

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). Press
the set into the valve body easily, without shearing the o-rings. Re-install one end cap,
gasket and bumper on the valve body. Using the arbor press or bench vise that was used
in disassembly, press the sleeve back into the valve body. 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 inspecting 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.

PlLOT VALVE

This assembly is reached by removing the air distribution valve body from the pump
and lifting the pilot valve body out of the intermediate housing. Follow the instruction
above for the air distribution valve when servicing the pilot valve.

When reinserting an externally serviceable pilot valve, push both plungers out of the
path of the pilot valve so that they and the pilot valve are not damaged.

Service Note: If a problem arises with the pilot valve, it is usually corrected by
replacing only o-rings. Always grease the spool prior to inserting into the sleeve. If the
sleeve is removed from the body, reinsertion must be from the same side it was removed
from, the chambered side. Again, grease the o-rings so that it slides into the body. Make
sure the retaining ring has securely been inserted around the sleeve.

Service Note: When re-installing pilot valve (Item 6), make sure that plunger pins
(Item 5) are both pushed as far as possible in, toward the diaphragms. Large head as
close to casting as possible; otherwise, these items may be damaged.

PILOT VALVE ACTUATOR

The bushings for the pilot valve actuators are threaded into the intermediate bracket
from the outside. The plunger may be removed for inspection or replacement from the
inside by removing the air distribution valve body and the pilot valve body from the pump.
The plungers should be visible through 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 be necessary to replace the o-ring seal.

To replace the o-ring, the bushing can be turned out through the inner chamber by
removing the outer chamber assembly to reach the bushing.

IMPORTANT

This pump is pressurized internally with air pressure during operation—always make
certain all bolting is in good condition and that all of correct bolting is reinstalled during

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.
