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: Viton

has a maximum
limit of 176.7°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 signifi cantly reduce maximum
safe operating temperatures. Consult Chemical
Resistance Guide (E4) for chemical compatibility
and temperature limits.

WARNING: Prevention of static sparking — If
static sparking occurs, fi re or explosion could
result. Pump, valves, and containers must be
grounded to a proper grounding point when
handling fl ammable fl uids and whenever
discharge of static electricity is a hazard.

CAUTION: Do not exceed 8.6 bar (125 psig) air
supply pressure.

CAUTION: The process fl uid and cleaning fl uids
must be chemically compatible with all wetted
pump components. Consult Chemical Resistance
Guide (E4).

CAUTION: Do not exceed 82°C (180°F) air inlet
temperature for Pro-Flo V™ models.

CAUTION: Pumps should be thoroughly fl ushed
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 fl uid
to fl ow 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 fi lter. A 5μ (micron)
air fi lter is recommended.

NOTE: When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure tight fi t.
(See torque specifi cations in Section 7.)

NOTE: Cast Iron PTFE-fi tted pumps come
standard from the factory with expanded PTFE
gaskets installed in the diaphragm bead of the
liquid chamber. PTFE gaskets cannot be re-used.
Consult PS-TG for installation instructions during
reassembly.

NOTE: Before starting disassembly, mark a line
from each liquid chamber to its corresponding air
chamber. This line will assis t in proper alignment
during reassembly.

CAUTION: Pro-Flo® pumps cannot be used in
submersible applications. Pro-Flo V™ is available
in both sub mersible and n on-subm ersible options.
Do not use non-submersible Pro-Flo V™ models
in submersible applications. Turbo-Flo™ pumps
can also be used in submersible applications.

CAUTION: Tighten all hardware prior to installation.

HOW IT WORKS—PUMP

The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show fl ow pattern
through the pump upon its initial stroke. It is assumed the pump has no fl uid in it prior to its initial stroke.

FIGURE 1 The air valve dir ects 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, balancing the
load and removing 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 fl uid into
the inlet manifold forcing the inlet valve
ball off its seat. Liquid is free to move
past the inlet valve ball and fi ll the liquid
chamber (see shaded area).

HOW IT WORKS—AIR DISTRIBUTION SYSTEM

FIGURE 2 When the pressurized diaphragm,
diaphr agm A, re ache s the limit of i ts dis charge
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 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 lift the discharge
valve ball off its seat, while the opposite
discharge valve ball is forced onto its seat,
forcing fl uid to fl ow 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 fl uid into the inlet
manifold of the pump. The inlet valve ball
is f or ce d of f it s seat a ll owing th e fl uid being
pumped to fi ll the liquid chamber.

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 shift 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.

®

patented air distribution system incorporates two

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 starting
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.

LIFT 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 which
can affect your pump’s operating characteristics. The

WILDEN PUMP & ENGINEERING, LLC 10 WIL-10110-E-02 8/06

number of intake and discharge elbows, viscosity of
pumping fl uid, elevation (atmospheric pressure) and
pipe friction loss all affect the amount of suction lift
your pump will attain.

Section 6

CALL 1-800-577-8111 FOR SALES AND SUPPORT

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 fl ex 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 fi ttings
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
fl oor. Multiple installations with confl icting 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
fi lter, needle valve and regulator. The use of an air fi lter
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 fi gure by the
displacement per stroke.

MUFFLER: Sound levels are reduced below OSHA
specifi cations using the standard Wilden muffl er. Other

WIL-10110-E-02 8/06 11 WILDEN PUMP & ENGINEERING, LLC

muffl ers 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 effi ciency 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 fi ttings 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 fi ttings.

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 specifi cs.

When pumps are installed in applications involving fl ooded
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 effi cient
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: Pro-Flo V™ pumps can be
used for submersible applications, when using the Pro-Flo
V™ submersible option. Turbo-Flo™ pumps can also be
used for submersible applications.

NOTE: Pro-Flo

ALL WILDEN PUMPS ARE CAPABLE OF PASSING SOLIDS.

NOTE: In the event of a power failure, the shut off valve
should be closed, if the restarting of the 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 off 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.

CALL 1-800-577-8111 FOR SALES AND SUPPORT

SUGGESTED OPERATION & MAINTENANCE

OPERATION: The P15 and PV15 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 ASSEMBLY/DISASSEMBLY INSTRUCTIONS.

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 fl ow 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

TROUBLESHOOTING

be restarted by reducing the fl uid discharge pressure
or increasing the air inlet pressure. The Wilden P15
and PV15 pumps run solely on compressed air and
does not generate heat, therefore your process fl uid
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 fl uid
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 fi lter for debris (see recommended

installation).

3. Check for extreme air leakage (blow by) which

would indicate worn seals/bores in the air valve,
pilot spool, main shaft.

4. Disassemble pump and check for obstructions

in the air passageways or objects which 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 which 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 fl ows.

1. Check for pump cavitation; slow pump speed

down to allow thick material to fl ow 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
c o m p r e s s e d a i r . A l t e r n a t i v e l y , a c o a l e s c i n g fi lter may
be used to remove the water from the compressed

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.

SHAFT SEAL

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 ( hea t shrink tubing may also b e used). This is d one
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 fi ngers pull down on the top portion of
the seal to form kidney bean 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 par tially 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 fi nger. With either the side
of the screwdriver or your fi nger, 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
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.
