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 177°C (3 50°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 (E4) for chemical compatibilit y
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 wet ted 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 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: Bef ore any maintenance or repair i s attemp ted,
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: Cast Iron PTFE-fitted 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 assist in proper alignment during reassembly.
CAUTION: Pro-Flo® pumps cannot be used in
submersible applications. Pro-Flo X ™ is available in both
single-point exhaust (submersible) and standard (nonsubmersible) options. Do not use standard Pro-Flo X™
models in submersible applications. Turbo-Flo
®
pumps
are also available in a single-point exhaust (submersible)
configuration.
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 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, 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 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 redirec ts
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 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.
WIL-11540-E-01 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 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.

Step 1:
Identifying performance at setting 4. Locate
the curve that represents the flow 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 flow curve,
draw a vertical line downward until reaching
the bottom scale on the chart. Identify the flow

(See figure 4.)
Step 3
: Determine flow X Factor. Divide the required
flow rate 18.9 lpm (5 gpm) by the setting 4 flow

the flow curves for EMS setting 1 and 2). Observe the location of the point relative to the
two curves it lies between and approximate
the EMS setting (Figure 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.

: Determine air X Factor. In order to determine
the air X Factor, identify the two air EMS setting curves closest to the EMS setting established in example 2.1 (in this case, the point
lies between the air curves for EMS setting

setting (1.8) must be approximated and plotted on the EMS curve along the horizontal
line representing your discharge pressure (in
this case, 40 psig). This air point is different

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 the following
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
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: Pro-FloX™ pumps can
be used for submersible applications, when using the
Pro-Flo X™ single-point exhaust option. Turbo-Flo™ pumps
are also available in a single-point exhaust (submersible)
configuration.

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.

Page 28
SUGGESTED OPERATION & MAINTENANCE
OPERATION: The PX820/PX830 is 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. 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. The Wilden PX820/
PX830 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 of fer 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) which
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 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 flows.
1. Check for pump cavitation; slow pump speed
down to allow thick material to flow into liquid
chambers.
WILDEN PUMP & ENGINEERING, LLC 26 WIL-11540-E-01
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.
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.

REASSEMBLY HINTS & TIPS
AS SE MB 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 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.
• 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 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 partially snap back to its
original shape.
• Af ter 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 shaf t with a rotating motion.
This will complete the resizing of the seal.
• Perform these steps for the remaining seal.
