NOTE: UL listed confi gured pumps have the following
temperature limits:
UL 79 Buna- -12.2 °C (10 °F) to 52°C (12 5°F)
CAUTION: When choosing pump materials, be sure to check
the temperature limits for all wetted components. Example:
®
Viton
has a max imum limi t of 176 .7°C ( 350 °F) b ut poly propyle ne
has a maximum limit of only 79 °C (17 5°F).
CAUTION: Maximum temperature limits are based upon
mechanical stress only. Certain chemicals will signi fi cantly
reduce maximum safe operating temperatures. Consult
Chemical Resis tance Guide (E4) for chemical compatibility and
temperature limits.
WARNING: Prevention of stat ic 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: Canadian St andards Association (C SA) confi gured
pumps must be electrically grounded using the grounding
location identifi ed. Improper grounding can cause improper
and dangerous operation.
CAUTION: Do not exceed 8.6 bar (12 5 psig ) air supply
pressure.
CAUTION: Canadian St andards Association (C SA) confi gured
pumps should not exceed 6.9 bar (10 0 psig ) sweet gas supply
pressure.
CAUTION: For U.L. listed pumps, do not exceed 3.4 bar (50
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 X™ 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 l ter. 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 P TFE gaskets ins talled 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

HOW IT WORKS
The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show the flow pattern
through the pump upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke.
BA B A BA
OPEN
FIGURE 1 The air valve directs pressurized 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 block 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 block 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).
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 block while pulling diaphragm A to the center block. 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 fluid to flow through the pump discharge.
The movement of diaphragm A toward the center
block 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.
®
The Pro -Flo
patented air distribution system incorporates two
moving parts : the air valve spool and the pilot spool. The hear t 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 direc ts
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.
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.

curve. For this example we will be using 4.1 bar (60 psig) inlet
air pressure and 2.8 bar (40 psig) discharge pressure and EMS
setting 2.
Step 1:
Identifying performance at setting 4. Locate
the curve that represents the fl ow rate of the
pump with 4.1 bar (60 psig) air inlet pressure.
Mark the point where this curve crosses the
horizontal line representing 2.8 bar (40 psig)
discharge pressure. (Figure 1). After locating
your performance point on the fl ow curve,
draw a vertical line downward until reaching
the bottom scale on the chart. Identify the fl ow

of performance point relative to air consumption curves and approximate air consumption

Calculating performance for specific EMS
setting. Multiply the fl ow rate (8.2 gpm)
obtained in Step 1 by the fl ow X Factor multiplier (0.58) in Step 2 to determine the fl ow rate
at EMS setting 2. Multiply the air consumption (9.8 scfm) obtained in Step 1 by the air

setting curves (in this case, the point lies between the fl ow curves for EMS setting 1 and

to the two curves it lies between and approximate the EMS setting (fi gure 5). For more precise results you can mathematically interpolate between the two curves to determine the
optimal EMS setting.
For this example the EMS setting is 1.8.

PX1 METAL
SUCTION LIFT CURVE
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 number of intake and dis-
WIL-10300-E-10 19 WILDEN PUMP & ENGINEERING, LLC
charge elbows, viscosity of pumping fluid, elevation (atmospheric pressure) and pipe friction loss all affect the amount
of suction lift your pump will attain.
Page 22
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, 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.
NOTE: Canadian Standards Association (CSA) confi gured pumps
should not exceed 6.9 bar (100 psig) sweet gas supply pressure.
ONLY CSA confi gured pumps should be operated using gas.
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 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.
For U.L. listed pumps, all installation must conform with NFPA 30,
NFPA 30A, and other applicable codes. All pipe connections are
to be made using U.L. classifi ed gasoline-resistant pipe compound.
Exhaust port is to be connected to pipe or tubing to be routed
outdoors or other location determined to be equivalent.
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 X™ pumps can
be used for submersible applications, when using the
Pro-Flo X™ submersible option. Turbo-Flo™ pumps can also be
used for submersible applications.
NOTE: Pro-Flo® and Accu-Flo™ pumps are not submersible.
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.
CAUTION: CANADIAN STANDARDS ASSOCIATION (CSA)
CONFIGURED PUMPS SHOULD NOT EXCEED 6.9 BAR (100 PSIG)
SWEET GAS SUPPLY PRESSURE.
CAUTION: FOR U.L. LISTED PUMPS, DO NOT EXCEED 3.4 BAR (50
PSIG) AIR SUPPLY PRESSURE.

SUGGESTED INSTALLATION
This illustration is a generic
representation of an air-operated
double-diaphragm pump.
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.
WIL-10300-E-10 21 WILDEN PUMP & ENGINEERING, LLC
Page 24
SUGGESTED OPERATION & MAINTENANCE
OPERATION: P1 and PX1 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
ASSEMBLY/DISASSEMBLY 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
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 be restarted by reducing the fl uid
discharge pressure or increasing the air inlet pressure.
TROUBLESHOOTING
The P1 and PX1 pumps run solely on compressed air
and do not generate heat, therefore your process fl uid
temperature will not be affected.
NOTE: Canadian Standards Association (CSA) confi gured
pumps run solely on gas and do not generate heat.
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 0.3 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 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 shif t.
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.
WILDEN PUMP & ENGINEERING, LLC 22 WIL-10300-E-10
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
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.

rotating the diaphragm by hand,
remove the diaphragm assembly
from the center section.
Step 11A
Due to varying torque values, one
of the two situations will occur:
A) The outer piston, diaphragm
and inner piston will separate
from the shaft which remains
connected to the opposite side
diaphragm assembly.
Step 11B
B) The diaphragm assembly and
shaft remain connected leaving
the opposite side diaphragm
assembly within the opposite
side of the center section
assembly.
GROUNDING STRAP FOR CSA PX1 PUMPS
Step 12
To remove the diaphragm assembly
from the shaft, secure shaft with
soft jaws (a vise fi tted with plywood
or other suitable material) to ensure
shaft is not nicked, scratched,
or gouged. Using an adjustable
wrench, remove the diaphragm
assembly from shaft. Inspect all
parts for wear and replace with
genuine Wilden parts if necessary.
WIL-10300-E-10 25 WILDEN PUMP & ENGINEERING, LLC
Canadian Standards Association (CSA) confi gured pumps must be
electrically grounded using the grounding strap provided (fi gure 1).
Improper grounding can cause improper and dangerous operation.
To properly attach the grounding strap to a CSA confi gured PX1 pump,
position the grounding strap eyelet between the two 7/16" clamp band nuts
and tighten to secure the grounding strap (fi gure 2). NOTE: Two 7/16" nuts
must be used when securing the grounding strap to the pump. This is
done to avoid loosening the large clamp band and possibly creating a gas
leak. Grounding the pump must be done in accordance with local codes,
or in the absence of local codes, an industry or nationally recognized code
having jurisdiction over the specifi ed installation.

REASSEMBLY HINT & TIPS
ASSEMBLY:
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.
• Clean the inside of the center section shaft bore to ensure
no damage is done to new seals.
• Stainless bolts should be lubed to reduce the possibility of
seizing during tightening.
• Level the water chamber side of the intake/discharge
manifold to ensure a proper sealing surface. This is most
easily accomplished by placing them on a flat surface
prior to tightening their clamp bands to the desired torque
(see this page for torque specs).
• Be sure to tighten outer pistons simultaneously on PTFEfitted pumps to ensure proper torque values.
• Ensure proper mating of liquid chambers to manifolds
prior to tightening vertical bolts. Overhang should be
equal on both sides.
• Apply a small amount of Loctite 242 to the shaft interval
threads before the diaphragm assembly.
• Concave side of disc spring in diaphragm assembly faces
toward shaft.
