NOTE: Not all materials are available for all
models. Refer to Section 2 for the material
options available for your pump.
CAUTION: When choosing pump materials, be
sure to check the temperature limits for all wetted
components. Example: Viton® has a maximum
limit of 177°C (350°F), but polypropylene has a
maximum limit of only 79°C (175°F).
CAUTION : Maximum temperature limits are
based upon mechanical stress only. Certain
chemicals will significantly reduce maximum
safe operating temperatures. Consult Chemical
Resistance Guide for chemical compatibility and
temperature limits.
WARNING : Prevent static sparking — If static
sparking occurs, fire or explosion could result.
Pump, valves and containers must be grounded
to a proper grounding point when handling
flammable fluids and whenever discharge of
static electricity is a hazard.
CAUTION: Do not exceed 8.6 bar (125 psig) air
supply pressure.
CAUTION: The process fluid and cleaning fluids
must be chemically compatible with all wetted
pump components. Consult Chemical Resistance
Guide.
CAUTION: Do not exceed 82°C (180°F) air inlet
temperature for Pro-Flo® SHIFT models.
CAUTION: Pumps should be thoroughly flushed
before installing into process lines. FDA- and
USDA-approved pumps should be cleaned and /
or sanitized before being used.
CAUTION: Always wear safety glasses when
operating pump. If diaphragm rupture occurs,
material being pumped may be forced out air
exhaust.
CAUTION: Before any maintenance or repair is
attempted, the compressed air line to the pump
should be disconnected and all air pressure
allowed to bleed from pump. Disconnect all
intake, discharge and air lines. Drain the pump
by turning it upside down and allowing any fluid
to flow into a suitable container.
CAUTION: Blow out air line for 10 to 20 seconds
before attaching to pump to make sure all pipeline
debris is clear. Use an in-line air filter. A 5μ
(micron) air filter is recommended.
NOTE: Before starting disassembly, mark a line
from each liquid chamber to its corresponding air
chamber. This line will assist in proper alignment
during reassembly.
CAUTION: Pro-Flo® SHIFT is available in
both single-point exhaust (submersible) and
standard (non-submersible) options. Do not use
standard Pro-Flo® SHIFT models in submersible
applications.
CAUTION: Tighten all hardware prior to installation.

Section 1
HOW IT WORKS—PUMP
The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show flow pattern
through the pump upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke.
FIGUR E 1 The air valve dire cts pre ssurized
air to the back side of diaphragm A. The
compressed air is applied directly to the
liquid column separated by elastomeric
diaphragms. The diaphragm ac ts as
a separation membrane bet ween the
compressed air and liquid; a balanced
load removes mechanical stress from the
diaphragm. The compressed air moves
the diaphragm away from the center of
the pump. The opposite diaphragm is
pulled in by the shaft connected to the
pressurized diaphragm. Diaphragm B
is on its suction stroke; air behind the
diaphragm has been forced out to the
atmosphere through the exhaust port of
the pump. The movement of diaphragm
B toward the center of the pump creates
a vacuum within chamber B. A tmospheric
pressure forces fluid into the inlet
manifold forcing the inlet valve ball off its
seat. Liquid is free to move past the inlet
valve ball and fill the liquid chamber (see
shaded area).
HOW IT WORKS—AIR DISTRIBUTION SYSTEM
FIGURE 2 When the pressurized
diaphragm, diaphragm A, reaches the limit
of its discharge stroke, the air valve redirects
pressurized air to the back side of diaphragm
B. The pressurized air forces diaphragm
B away from the center while pulling
diaphragm A to the center. Diaphragm B is
now on its discharge stroke. Diaphragm B
forc es the inlet valve b all onto its se at due to
the hydraulic forces developed in the liquid
chamber and manifold of the pump. These
same hydraulic forces lift the discharge
valve ball off its seat, while the opposite
discharge valve ball is forced onto its seat,
forcing fluid to flow through the pump
discharge. The movement of diaphragm A
toward the center of the pump creates a
vacuum within liquid chamber A. Atmospheric pressure forces fluid into the inlet
manifold of the pump. The inlet valve ball
is forced off its seat allowing the fluid
being pumped to fill the liquid chamber.
FIGURE 3 At completion of the stroke,
the air valve again redirects air to the
back side of diaphragm A, which starts
diaphragm B on its exhaust stroke. As
the pump reaches its original star ting
point, each diaphragm has gone through
one exhaust and one discharge stroke.
This constitutes one complete pumping
cycle. The pump may take several cycles
to completely prime depending on the
conditions of the application.
The heart of the patented Pro-Flo® SHIFT Air Distribution
System (ADS) is the air valve assembly. The air valve design
incorporates an unbalanced spool with the small end of the
spool being pressurized continuously while the large end of
the spool is alternately pressurized, then exhausted to move
the spool. The air valve spool directs pressurized air to one
chamber while exhausting the other. The air forces the main
shaft/diaphragm assembly to move to one side – discharging
liquid on that side and pulling liquid in on the other side. When
the shaft reaches the end of the stroke, the inner piston actuates
the pilot spool, which controls the air to the large end of the air
valve spool. The repositioning of the air valve spool routes the
air to the other air chamber. The air control spool allows air to
flow freely into the air chamber for the majority of each pump
stroke, but it significantly restricts the flow of air into the air
chamber when activated by the inner piston near the end of the
each stroke.

Section 6
SUGGESTED INSTALLATION
Wilden pumps are designed to meet the performance
requirements of even the most demanding pumping
applications. They have been designed and manufactured
to the highest standards and are available in a variety of
liquid-path materials to meet your chemical-resistance
needs. Refer to the performance section of this manual for
an in-depth analysis of the performance characteristics of
your pump. Wilden offers the widest variety of elastomer
options in the industry to satisfy temperature, chemicalcompatibility, abrasion-resistance and flex concerns.
The suction pipe size should be at least the equivalent or
larger than the diameter size of the suction inlet on your
Wilden pump. The suction hose must be non-collapsible,
reinforced type as these pumps are capable of pulling a high
vacuum. Discharge piping should also be the equivalent
or larger than the diameter of the pump discharge which
will help reduce friction losses. It is critical that all fittings
and connections are airtight or a reduction or loss of pump
suction capability will result.
INSTALLATION: Months of careful planning, study,
and selection efforts can result in unsatisfactory pump
performance if installation details are left to chance.
Premature failure and long term dissatisfaction can be
avoided if reasonable care is exercised throughout the
installation process.
LOCATION: Noise, safety, and other logistical factors usually
dictate where equipment will be situated on the production
floor. Multiple installations with conflicting requirements
can result in congestion of utility areas, leaving few choices
for additional pumps.
Within the framework of these and other existing conditions,
every pump should be located in such a way that six key
factors are balanced against each other to maximum
advantage.
ACCESS: First of all, the location should be accessible. If
it is easy to reach the pump, maintenance personnel will
have an easier time carrying out routine inspections and
adjustments. Should major repairs become necessary, ease
of access can play a key role in speeding the repair process
and reducing total downtime.
AIR SUPPLY: Every pump location should have an air line
large enough to supply the volume of air necessary to
achieve the desired pumping rate. Use air pressure up to
a maximum of 8.6 bar (125 psig) depending on pumping
requirements.
For best results, the pumps should use a 5µ (micron) air
filter, needle valve and regulator. The use of an air filter
before the pump will ensure that the majority of any pipeline
contaminants will be eliminated.
SOLENOID OPERATION: When operation is controlled by a
solenoid valve in the air line, three-way valves should be
used. This valve allows trapped air between the valve and
the pump to bleed off which improves pump performance.
Pumping volume can be estimated by counting the number
of strokes per minute and then multiplying the figure by the
displacement per stroke.
MUFFLER: Sound levels are reduced below OSHA
specifications using the standard Wilden muffler. Other
mufflers can be used to further reduce sound levels, but
they usually reduce pump performance.
ELEVATION: Selecting a site that is well within the pump’s
dynamic lift capability will ensure that loss-of-prime issues will
be eliminated. In addition, pump efficiency can be adversely
affected if proper attention is not given to site location.
PIPING: Final determination of the pump site should not be
made until the piping challenges of each possible location
have been evaluated. The impact of current and future
installations should be considered ahead of time to make
sure that inadvertent restrictions are not created for any
remaining sites.
The best choice possible will be a site involving the
shortest and straightest hookup of suction and discharge
piping. Unnecessary elbows, bends, and fittings should
be avoided. Pipe sizes should be selected to keep friction
losses within practical limits. All piping should be supported
independently of the pump. In addition, the piping should
be aligned to avoid placing stress on the pump fittings.
Flexible hose can be installed to aid in absorbing the forces
created by the natural reciprocating action of the pump. If the
pump is to be bolted down to a solid location, a mounting
pad placed between the pump and the foundation will assist
in minimizing pump vibration. Flexible connections between
the pump and rigid piping will also assist in minimizing
pump vibration. If quick-closing valves are installed at any
point in the discharge system, or if pulsation within a system
becomes a problem, a surge suppressor (SD Equalizer
should be installed to protect the pump, piping and gauges
from surges and water hammer.
If the pump is to be used in a self-priming application, make
sure that all connections are airtight and that the suction lift is
within the model’s ability. NOTE: Materials of construction and
elastomer material have an effect on suction lift parameters.
Please refer to the performance section for specifics.
When pumps are installed in applications involving flooded
suction or suction head pressures, a gate valve should be
installed in the suction line to permit closing of the line for
pump service.
Pumps in service with a positive suction head are most efficient
when inlet pressure is limited to 0.5–0.7 bar (7–10 psig).
Premature diaphragm failure may occur if positive suction
is 0.7 bar (10 psig) and higher.
SUBMERSIBLE APPLICATIONS: Turbo-Flo™ pumps can be
used for submersible applications. Pro-Flo
are available in a single-point exhaust (submersible)
configuration.
ALL WILDEN PUMPS ARE CAPABLE OF PASSING SOLIDS.
A STRAINER SHOULD BE USED ON THE PUMP INTAKE TO
ENSURE THAT THE PUMP'S RATED SOLIDS CAPACITY IS
NOT EXCEEDED.
CAUTION: DO NOT EXCEED 8.6 BAR (125 PSIG) AIR
SUPPLY PRESSURE.

NOTE: In the event of a power failure, the shut-off
valve should be closed, if restarting of pump is not
desirable once power is regained.
AIR-OPERATED PUMPS: To stop the pump from
operating in an emergency situation, simply close the
shut-of f valve (user-supplied) installed in the air supply
line. A properly functioning valve will stop the air supply
to the pump, therefore stopping output. This shut-off
valve should be located far enough away from the
pumping equipment such that it can be reached safely
in an emergency situation.

SUGGESTED OPERATION & MAINTENANCE
OPERATION: PS Stallion pumps are pre-lubricated,
and do not require in-line lubrication. Additional
lubrication will not damage the pump, however if the
pump is heavily lubricated by an external source, the
pump’s internal lubrication may be washed away. If
the pump is then moved to a non-lubricated location,
it may need to be disassembled and re-lubricated as
described in the DISASSEMBLY/REASSEMBLY.
Pump discharge rate can be controlled by limiting
the volume and/or pressure of the air supply to the
pump. An air regulator is used to regulate air pressure.
A needle valve is used to regulate volume. Pump
discharge rate can also be controlled by throttling
the pump discharge by partially closing a valve in
the discharge line of the pump. This action increases
friction loss which reduces flow rate. (See Section 5.)
This is useful when the need exists to control the pump
from a remote location. When the pump discharge
pressure equals or exceeds the air supply pressure,
the pump will stop; no bypass or pressure relief valve
is needed, and pump damage will not occur. The
pump has reached a “deadhead” situation and can be
TROUBLESHOOTING
restarted by reducing the fluid discharge pressure or
increasing the air inlet pressure. PS Stallion pumps
run solely on compressed air and do not generate
heat, therefore your process fluid temperature will not
be affected.
MAINTENANCE AND INSPECTIONS: Since each
application is unique, maintenance schedules may
be different for every pump. Frequency of use, line
pressure, viscosity and abrasiveness of process fluid
all affect the parts life of a Wilden pump. Periodic
inspections have been found to offer the best
means for preventing unscheduled pump downtime.
Personnel familiar with the pump’s construction and
service should be informed of any abnormalities that
are detected during operation.
RECORDS: When service is required, a record should
be made of all necessary repairs and replacements.
Over a period of time, such records can become a
valuable tool for predicting and preventing future
maintenance problems and unscheduled downtime. In
addition, accurate records make it possible to identify
pumps that are poorly suited to their applications.
Pump will not run or runs slowly.
1. Ensure that the air inlet pressure is at least 0.4 bar
(5 psig) above startup pressure and that the differential
pressure (the difference between air inlet and liquid
discharge pressures) is not less than 0.7 bar (10 psig).
2. Check air inlet filter for debris (see SUGGESTED
INSTALLATION).
3. Check for extreme air leakage (blow by) that would
indicate worn seals /bores in the air valve, pilot
spool and main shaft.
4. Disassemble pump and check for obstructions in
the air passageways or objects that would obstruct
the movement of internal parts.
5. Check for sticking ball check valves. If material being
pumped is not compatible with pump elastomers,
swelling may occur. Replace ball check valves and
seals with proper elastomers. Also, as the check
valve balls wear out, they become smaller and can
become stuck in the seats. In this case, replace balls
and seats.
6. Check for broken inner pistons that will cause the
air valve spool to be unable to shift.
7. Remove plug from pilot spool exhaust.
Pump runs, but little or no product flows.
1. Check for pump cavitation; slow pump speed down
to allow thick material to flow into liquid chambers.
2. Verify that vacuum required to lift liquid is not
greater than the vapor pressure of the material
being pumped (cavitation).
3. Check for sticking ball check valves. If material being
pumped is not compatible with pump elastomers,
swelling may occur. Replace ball check valves and
seats with proper elastomers. Also, as the check
valve balls wear out, they become smaller and can
become stuck in the seats. In this case, replace balls
and seats.
Pump air valve freezes.
1. Check for excessive moisture in compressed
air. Either install a dryer or hot air generator for
compressed air. Alternatively, a coalescing filter
may be used to remove the water from the
compressed air in some applications.

REASSEMBLY HINTS & TIPS
AS SEM B LY:
Upon performing applicable maintenance to the air
distrib ution system, t he pump can now be re assembled .
Please refer to the disassembly instructions for photos
and parts placement. To reassemble the pump, follow
the disassembly instructions in reverse order. The air
distribution system needs to be assembled first, then
the diaphragms and finally the wetted path. Please
find the applicable torque specifications on this page.
The following tips will assist in the assembly process.
• Lubricate air valve bore, center section shaft
and pilot spool bore with NLGI grade 2 white EP
bearing grease or equivalent.
• Clean the inside of the center section shaft bore to ensure
no damage is done to new shaft seals.
• A small amount of NLGI grade 2 white EP bearing grease
can be applied to the muffler and air valve gaskets to
lubricate gaskets during assembly.
• Make sure that the exhaust port on the muffler plate is
centered between the two exhaust ports on the center
section.
• Stainless bolts should be lubed to reduce the possibility
of seizing during tightening.
• Use a mallet to tamp lightly on the large clamp bands to
seat the diaphragm before tightening.

SHAFT SEAL INSTALLATION:
PRE-INSTALLATION
• Once all of the old seals have been removed, the
inside of the bushing should be cleaned to ensure
no debris is left that may cause premature damage
to the new seals.
INSTALLATION
The following tools can be used to aid in the installation
of the new seals:
Needle-Nose Pliers
Phillips Screwdriver
Electrical Tape
• Wrap electrical tape around each leg of the needle-nose
pliers (heat shrink tubing may also be used). This is done
to prevent damaging the inside surface of the new seal.
• With a new seal in hand, place the two legs of the
needle-nose pliers inside the seal ring. (See Figure A.)
• Open the pliers as wide as the seal diameter will allow,
then with two fingers pull down on the top portion of
the seal to form a kidney shape. (See Figure B.)
• Lightly clamp the pliers together to hold the seal into
the kidney shape. Be sure to pull the seal into as tight
of a kidney shape as possible, this will allow the seal to
travel down the bushing bore easier.
• With the seal clamped in the pliers, insert the seal into
the bushing bore and position the bottom of the seal
into the correct groove. Once the bottom of the seal is
seated in the groove, release the clamp pressure on the
pliers. This will allow the seal to partially snap back to its
original shape.
• After the pliers are removed, you will notice a slight
bump in the seal shape. Before the seal can be properly
resized, the bump in the seal should be removed as
much as possible. This can be done with either the
Phillips screwdriver or your finger. With either the side
of the screwdriver or your finger, apply light pressure
to the peak of the bump. This pressure will cause the
bump to be almost completely eliminated.
• Lubricate the edge of the shaft with
white EP bearing grease.
• Slowly insert the center shaft with a rotating motion.
This will complete the resizing of the seal.
• Perform these steps for the remaining seals.
