NOTE: Not all materials are available for all models.
Refer to Section 2 for material options for your
pump.
CAUTION : When choosing pump materials, be
sure to check the temperature limits for all wetted
components. Example: FKM 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.
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 the Chemical Resistance Guide.
CAUTION: Pumps should be thoroughly flushed
before installing into process lines. FDA- and USDAapproved 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: When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure tight fit.
(See torque specifications in Section 7.)
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: Tighten all hardware prior to installation.
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.

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 acts as
a separation membrane between 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
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. Atmospheric
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).

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 forces the
inlet valve ball onto its seat due to the
hydraulic forces developed in the liquid
chamber and manifold of the pump. These
same hydraulic forces lif t 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 suction stroke. As
the pump reaches its original starting
point, each diaphragm has gone through
one suction 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.

WIL-11570 - E - 02 3 WILDEN PUMP & ENGINEERING, LLC
The Pro-Flo
moving parts : the air valve spool and the pilot spool. The heart of
the system is the air valve spool and air valve. This valve design
incorporates an unbalanced spool. The smaller end of the spool
is pressurized continuously, while the large end is alternately
pressurized then exhausted to move the spool. The spool directs
pressurized air to one air chamber while exhausting the other.
The air causes the main shaft /diaphragm assembly to shif t to
one side — discharging liquid on that side and pulling liquid in
on the other side. When the shaft reaches the end of its stroke,
the inner piston actuates the pilot spool, which pressurizes and
exhausts the large end of the air valve spool. The repositioning
of the air valve spool routes the air to the other air chamber.

CAPABILITY
Suction-lift curves are calibrated for
pumps operating at 305 m (1,000')
above sea level. This chart is meant
to be a guide only. There are many
variables that can affect your pump's
operating characteristics. The number
of intake and discharge elbows,
viscosity of pumping fluid, elevation
(atmospheric pressure) and pipe
friction loss all affect the amount of
suction lift your pump will attain.

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, chemical
compatibility, 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’s 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 assure 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 hook-up 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 tprotect 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.
NOTE: Pro-Flo
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

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.

Page 13
SUGGESTED OPERATION & MAINTENANCE
OPERATION: The Pro-Flo® 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 INSTRUCTIONS.
Pump discharge rate can be controlled by limiting the
volume and/or pressure of the air supply to the pump. A
regulator is used to control air pressure while a needle
valve is used to control 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 restarted by reducing the fluid
TROUBLESHOOTING
discharge pressure or increasing the air inlet pressure.
The Pro-Flo
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.

pumps run solely on compressed air and
Pump will not run or runs slowly.
1. Ensure that the air inlet pressure is at least 0.3 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 piston that will cause the air
valve spool to be unable to shif t.
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.
WIL-11570 - E - 02 11 WILDEN PUMP & ENGINEERING, LLC
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
compre ssed air. Alternativel y, a c oalescing filter may
be used to remove the water from the compressed
air in some applications.
Air bubbles in pump discharge.
1. Check for ruptured diaphragm.
2. Check tightness of outer pistons (refer to Section 7).
3. Check tightness of fasteners and integrity of
O-rings and seals, especially at intake manifold.
4. Ensure pipe connections are airtight.
Product comes out air exhaust.
1. Check for diaphragm rupture.
2. Check tightness of outer pistons to shaft.

REASSEMBLY HINTS & TIPS
RE AS SE MB LY:
Upon performing applicable maintenance to the air
distribution system, the pump can now be reassembled.
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 locate 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.

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 needlenose 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 NLGI grade 2 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.
