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 significantly reduce maximum safe operating
temperatures. Consult engineering guide for
chemical compatibility and temperature limits.
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 pipe line
debris is clear. Use an in-line air filter. A 5µ (micron)
air filter is recommended.
NOTE: Tighten clamp bands prior to installation.
Fittings may loosen during transportation.
NOTE: When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure tight fit.
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: Always wear safety glasses when
operating pump. If diaphragm rupture occurs,
material being pumped may be forced out air
exhaust.
WARNING: Prevention of static sparking — If static
sparking occurs, fire or explosion could result.
Pump, valves, and containers must be properly
grounded 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: Plastic series pumps are made of virgin
plastic and are not UV stabilized. Direct sunlight
for prolonged periods can cause deterioration of
plastics.
CAUTION: Verify the chemical compatibility of
the process and cleaning fluid to the pump’s
component materials in the Chemical Resistance
Guide (see E4).
CAUTION: Only explosion proof (NEMA 7)
solenoid valves should be used in areas where
explosion proof equipment is required.
NOTE: Non lube-free pumps must be lubricated.
Wilden suggests an arctic 5 weight oil (ISO
grade 15). Do not over-lubricate air supply. Overlubrication will reduce pump performance.
NOTE: P1 Plastic PTFE-fitted pumps come standard
from the factory with expanded PTFE gaskets. (See
Gasket Kit Installation in Section 8E.)
CAUTION: Do not over-tighten the air valve bolts.
Too much torque on the air valve bolts may damage
the air valve muffler plate. Do not exceed 3.3 N•m
(29 in-lbs).

HOW IT WORKS—PUMP
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.
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.
Figure A
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.
The Pro-Flo® patented air distribution system
incorporates three moving parts: the air valve
spool, the pilot spool, and the main shaft/diaphragm assembly. The heart of the system
is the air valve spool and air valve. As shown
in Figure A, 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.

SUCTION LIFT CURVE
P1 PLASTIC
SUCTION LIFT CAPABILITY
Suction lift curves are calibrated for pumps
operating at 305 m
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 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
®
The Pro-Flo
(1/2") outlet and is designed for flows to 56.8 lpm (15 gpm).
The P1 Plastic pump is manufactured with wetted parts
of pure, unpigmented PVDF, PTFE PFA or polypropylene.
The P1 Plastic is constructed with a polypropylene center
section. A variety of diaphragms and o-rings are available
to satisfy temperature, chemical compatibility, abrasion and
flex concerns.
The suction pipe size should be at least 13 mm (1/2") diameter or larger if highly viscous material is being pumped.
The suction hose must be non-collapsible, reinforced type
as the P1 is capable of pulling a high vacuum. Discharge
piping should be at least 13 mm (1/2"); larger diameter can
be used to 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 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 five 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 (see Section 5). 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 insure 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, thus allowing trapped air to bleed off and improving
pump performance. Pumping volume can be set by counting
the number of strokes per minute and multiplying by displacement per stroke.
Sound levels are reduced below OSHA specifications using
the standard Wilden muffler element. Other mufflers can be
used but usually reduce pump performance.
model P1 has a 13 mm (1/2") inlet and 13 mm
ELEVATION: Selecting a site that is well within the pump’s
dynamic lift capability will assure that loss-of-prime troubles
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 problems 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 so as to keep friction
losses within practical limits. All piping should be supported
independently of the pump. In addition, the piping should
be aligned so as to avoid placing stresses 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 should
be installed to protect the pump, piping and gauges from
surges and water hammer.
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.
For P1 Plastic models, a non-raised surfaced-flange adapter
should be utilized when mating to the pump’s inlet and
discharge manifolds for proper sealing.
The P1 can be installed in submersible applications
only when both the wetted and non-wetted portions are
compatible with the material being pumped. If the pump is
to be used in a submersible application, a hose should be
attached to the pump’s air and pilot spool exhaust ports and
piped above the liquid level. The exhaust area for the pilot
spool is designed to be tapped for a 1/8" NPT fitting.
If the pump is to be used in a self-priming application, be
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 consult Wilden distributors for specifics.
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
10 psig and higher.
THE MODEL P1 PLASTIC WILL PASS 1.6 MM (1/16") SOLIDS.
WHENEVER THE POSSIBILITY EXISTS THAT LARGER SOLID
OBJECTS MAY BE SUCKED INTO THE PUMP, A STRAINER
SHOULD BE USED ON THE SUCTION LINE.
CAUTION: DO NOT EXCEED 8.6 BAR (125 PSIG) AIR
SUPPLY PRESSURE.

SUGGESTED INSTALLATION
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.
NOTE: In the event of a power failure, the shutoff
valve should be closed, if the restarting of the
pump is not desirable once power is regained.
®
SUGGESTED OPERATION & MAINTENANCE
OPERATION: Pump discharge rate can be controlled by
limiting the volume and/or pressure of the air supply to the
pump (preferred method). 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. 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 discharge pressure or increasing the air inlet pressure.
The Wilden P1 pump runs solely on compressed air and
does not generate heat, therefore your process fluid temperature will not be affected.
WILDEN PUMP & ENGINEERING, LLC WIL-10140-E-08
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.
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.

Section 5
TROUBLESHOOTING – AIR CONTROLLED
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 recommended 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 the 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 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.
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 8C.)
3. Check tightness of clamp bands 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.

DISASSEMBLY/REASSEMBLY
CAUTION:
compressed air line to the pump should be disconnected and
all air pressure allowed to bleed from the 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. Be aware of any hazardous effects of contact with
your process fluid.
The Wilden model P1 has a 13 mm (1/2") inlet and outlet and
is designed for flows up to 56.8 lpm (15 gpm). The single-piece
center section, consisting of center block and air chambers, is
molded of polypropylene or acetal. All fasteners and hardware
are stainless steel and the air valve is manufactured of brass or
high-tech engineered thermoplastic. Its air distribution system

AIR VALVE / CENTER BLOCK DISASSEMBLY
AIR VALVE DISASSEMBLY:
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 the
pump. Disconnect all intake, discharge, and air lines. Drain
the pump by turning it upside down and allowing any fluid

effects of contact with your process fluid.
The Wilden Plastic P1 utilizes a revolutionary Pro-Flo
distribution system. A 13 mm (1/2") air inlet connects the
air supply to the center section. Proprietary composite
seals reduce the co efficient of friction and allow the P1
to run lube-free. Constructed of acetal or polypropylene, the Pro-Flo

REASSEMBLY HINTS & 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.
