CAUTION:

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: 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. (3.4 bar [50 psig] for UL models.)

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 and retainers prior to
installation. Fittings may loosen during transportation.

When choosing pump materials, be sure to

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: Verify the chemical compatibility of the
process and cleaning fluid to the pump’s component
materials in the Chemical Resistance Guide.

CAUTION: When removing the end cap using
compressed air, the air valve end cap may come out
with considerable force. Hand protection such as a
padded glove or rag should be used to capture the
end cap.

CAUTION: Only explosion proof (NEMA 7) solenoid
valves should be used in areas where explosion proof
equipment is required.

NOTE: All non lube-free air-operated pumps must
be lubricated. Wilden suggests an arctic 5 weight oil
(ISO grade 15). Do not over-lubricate pump. Over-lubri­cation will reduce pump performance.

NOTE:

psig)

CAUTION: Do not lubricate lube-free pumps.

CAUTION: CAUTION: For UL listed pumps, do not

exceed 3.4 bar (50 psig) air supply pressure.

CAUTION: For UL listed pumps, all pipe connections
are to be made using UL Classified gasoline-resistant
pipe compound.

CAUTION: For UL listed pumps, all installations must
conform with NFPA 30, NFPA 30A, and all other appli­cable codes.

CAUTION: For UL listed pumps, air exhaust port is to
be connected to pipe or tubing to be routed outdoors
or other location determined to be equivalent.

CAUTION: For UL listed pumps, pump is to be
grounded using the jam-nut located atop the long
vertical carriage bolt. The ground connection is marked
with a tag having the grounding symbol.

UL-listed pumps must not exceed 3.4 bar (50

air supply pressure.

SECTION 3

THE WILDEN PUMP — 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.

RIGHT STROKE MID STROKE LEFT 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
from the diaphragm. The compressed
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).

stress

air

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 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.

SUCTION LIFT CURVES

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

SECTION 7A

INSTALLATION

The Model T2 Metal pump has a 25 mm (1”) inlet and 19 mm
(3/4”)

outlet and is designed for flows to 132 lpm (35 gpm).
The T2 Metal pump is manufactured with wetted parts of
aluminum or stainless steel. The center section of the T2
Metal pump is of aluminum or polypropylene construction.
The air distribution system consists of a brass air valve
body, aluminum air valve piston, Glyd™ rings and a bronze
center section bushing. A variety of diaphragms, valve balls,
valve seats, and o-rings are available to satisfy temperature,
chemical compatibility, abrasion and flex concerns.

The suction pipe size should be at least 25 mm (1”) diam­eter or larger if highly viscous material is being pumped.
The suction hose must be non-collapsible, reinforced type
as the T2 is capable of pulling a high vacuum. Discharge
piping should be at
used to reduce friction
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 that “utility” equipment be situated away from the
production floor. Multiple installations with conflicting
requirements can result in congestion of utility areas, leaving
few choices for siting of additional pumps.

Within the framework of these and other existing conditions,
every pump should be located in such a way that four key
factors are balanced against each other to maximum advan­tage.

1.

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.

2. 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 pump performance chart). Use
air pressure up to a maximum of 8.6 bar (125 psig) depend­ing upon pumping requirements. The use of an air filter
before the pump will ensure that the majority of any pipeline
contaminants will be eliminated. For best results, the pumps
should use an air filter, regulator, and lubricator system.

3. ELEVATION: Selecting a site that is well within the pump’s
suction 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 elevation
(see pump performance chart).

4. 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.

least 19 mm (3/4”); larger diameter can be

losses. It is critical that all fittings and

For UL listed pumps, all installations must conform with
NFPA 30, NFPA 30A, and all other applicable codes. All pipe
connections are to be made using UL Classified gasoline­resistant 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 the 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, it should line up without
placing stress on the pump fittings.

Expansion joints 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 foundation,
a mounting pad placed between the pump and 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.

The T2 can be used in submersible applications only when
both wetted and non-wetted portions are com patible 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 exhaust and the exhaust air piped above the liquid
level.

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 pump’s ability. Note: Materials of construction
and elastomer material have an effect on suction lift param­eters. Please refer to pump performance data.

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

0.8 bar (11 psig) and higher.

THE MODEL T2 WILL PASS 3.2 mm (1/8”) 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. (3.4 BAR [50 PSIG] FOR UL
MODELS.)

BLOW OUT AIR LINE FOR 10 TO 20 SECONDS BEFORE
ATTACHING TO PUMP TO MAKE SURE ALL PIPE LINE
DEBRIS IS CLEAR. ALWAYS USE AN IN-LINE AIR FILTER

SUGGESTED INSTALLATION

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.

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.

SECTION 7B

SUGGESTED OPERATION AND
MAINTENANCE INSTRUCTIONS

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 T2 pump runs solely on
compressed air and does not generate heat, therefore your
process fluid temperature will not be affected.

RECORDS:
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:
tion 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.

When service is required, a record should be

SECTION 7C – AIR OPERATION

TROUBLESHOOTING

Pump will not run or runs slowly.

1. Check air inlet screen and air filter for debris.

2. Check for sticking air valve, flush air valve in solvent.

3. Check for worn out air valve. If piston face in air valve is

shiny instead of dull, air valve is probably worn beyond
working tolerances and must be replaced.

4. Check center block Glyd™ rings. If worn excessively,

they will not seal and air will simply flow through pump
and out air exhaust. Use only Wilden Glyd™ rings as they
are of special construction.

5. Check for rotating piston in air valve.

6. Check type of lubricant being used. A higher viscosity

oil than suggested may cause the piston to stick or run
erratically. Wilden suggests the use of an oil with arctic
characteristics (ISO 15-5 wt.).

DIRECTIONS FOR DISASSEMBLY/REASSEMBLY

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 to flow into a suitable
container. Be aware of any hazardous effects of contact with
your process fluid.

The Wilden model T2 has a 25 mm (1”) inlet and 19 mm (3/4”)
outlet and is designed for flows up to 132 lpm (35 gpm). The
single-piece center section, consisting of center block and
air chambers, is molded of polypropylene or aluminum. The
air valve is manufactured of brass or high-tech, engineered
thermoplastics. All o-rings used in the pump are of a special
material and shore hardness that should only be replaced with
factory-supplied parts.

TOOLS REQUIRED:

Adjustable Wrench
9/16” Box Wrench
3/4” Box Wrench
Vise equipped with soft jaws (such as plywood, plastic
or other suitable material)

NOTE: The model used for these instructions incorporates
rubber diaphragms, balls, and seats. Models with PTFE
diaphragms, balls and seats are the same except where
noted.

DISASSEMBLY:

Step 1.

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

Figure 1

Step 2. Figure 2

Utilizing the 9/16” box wrench, start by removing the four long
carriage bolts that secure the top and bottom manifolds to the
center section.

WIL-10200-E-03 WILDEN PUMP & ENGINEERING, LLC

Step 3. Figure 3

Remove the top manifold and lift the center section off the inlet
manifold.

11

Step 4. Figure 4

Remove the discharge valve balls, seats
and o-rings from the discharge manifold
and inspect for nicks, gouges, chemical
attack or abrasive wear. Replace worn
parts with genuine Wilden parts for reli­able performance. PTFE o-rings should
be replaced when reassembled.

Step 5. Figure 5

Inspect the valve seat, valve seat o­ring, and valve ball from intake manifold.
Check for nicks, gouges, chemical attack
or abrasive wear. Replace worn parts with
genuine Wilden parts for reliable perfor­mance. PTFE o-rings should be replaced
when reassembled.

Step 6. Figure 6

With the 3/4” box wrench or by rotat­ing the diaphragm by hand, remove the
diaphragm assembly.

Step 7. Figure 7

NOTE: Due to varying torque values, one

of the following two situations may occur:

1) The outer piston, diaphragm and inner
piston remain attached to the shaft and
the entire assembly can be removed from
the center section.

Step 8. Figure 8

2)

The outer piston, diaphragm, inner
piston, and disc spring separate from the
shaft which remains connected to the
opposite side diaphragm assembly (Figure

8). PTFE-fitted pumps come standard with
back-up diaphragms (not shown).

Step 9. Figure 9

To remove the diaphragm assembly from
the shaft, secure shaft with soft jaws (a
vise fitted with plywood or other suitable
material) to ensure shaft is not nicked,
scratched, or gouged. Using an adjust­able wrench, remove diaphragm assem­bly from shaft. Inspect all parts for wear
and replace with genuine Wilden parts if
necessary.

SECTION 8B – TURBO-FLO™ PUMPS

AIR VALVE / CENTER SECTION
REPAIR / MAINTENANCE

The air valve assembly consists of the air valve body and
piston. The unique design of the air valve relies only on differ­ential pressure to cause the air valve to shift. It is reliable and
simple to maintain. The bushing in the center block, along
with the diaphragm shaft, provides the “trigger” to tell the
air valve to shift. The following procedure will ensure that the
air valve on your Wilden pump will provide long trouble-free
service.

AIR VALVE BODY AND PISTON
ASSEMBLY AND DISASSEMBLY

The air valve body and piston can be disconnected from the
pump by removing the four socket-head cap screws which
attach it to the center section. The piston in the air valve is
aluminum with a dark anodized coating (see Figure A). The
piston should move freely and the ports in the piston should
line up with the ports on the face of the air valve body. The
piston should also appear to be dull black in color. If the
piston appears to be a shiny aluminum color, the air valve
is probably worn beyond working tolerances and should be
replaced.

If the piston does not move freely in the air valve, the entire air
valve should be immersed in a cleaning solution. (NOTE: Do
not force the piston by inserting a metal object.) This soaking
should remove any accumulation of sludge and grit which is
preventing the air valve piston from moving freely. If the air
valve piston does not move freely after the above cleaning,
the air valve should be disassembled as follows: Remove
the snap ring from the top end of the air valve and apply an
air jet alternately to the two holes located in the face of the
air valve until the end cap is blown out. (See Figure B, next
page) [CAUTION: The air valve end cap may come out with
considerable force. Hand protection such as a padded glove
or a rag should be used to capture the end cap.] Inspect the
piston and cylinder bore for nicks and scoring.

Small nicks can usually be dressed out and the piston returned
to service. Inspect the cylinder end caps. Make sure that
the guide pin is straight and smooth or the piston will not
move freely in the cylinder. Clean out anti-centering pin holes
located on each side of the piston. Pin holes are located on
each side of the annular groove on the top of the piston and
travel to each end. New o-rings should be installed on the end
caps. Lubricate the o-rings and install the end caps, assuring
that proper alignment of the piston and cylinder ports is main­tained. Use an oil with arctic characteristics (ISO 15-5wt).

GLYD™ RING REPLACEMENT/
CENTER SECTION

The pump’s center section consists of a molded housing with
a bronze bushing. (Bushing is not removable.) This bushing
has grooves cut into the inside diameter. Glyd™ rings are
installed in these grooves. When the Glyd™ rings become
worn, they will no longer seal and must be replaced.

There are two versions of center sections: PRE-ENHANCED
(pumps manufactured before March 1, 1992) and ENHANCED
(pumps manufactured since March 1, 1992). An encircled
letter “E” stamped on the top of the center section denotes
the ENHANCED type center section (Figure C).

Please contact your local authorized distributor for
enhanced air distribution retrofit packages.

If the encircled “E” is present, an enhanced (02-3800-

03-07) shaft should be utilized to maximize performance.
The center section Glyd™ rings (02-3210-55-225) must be
installed in the appropriate grooves as shown (1, 3, 6, 8).

If the encircled “E” is not present, a pre-enhanced shaft
(02-3800-03 or 02-3820-03) must be utilized. An enhanced
(non-dented) shaft will not function correctly. The center
section o-rings (02-3200-52) must be installed in the appro­priate grooves as shown (1, 3, 4, 6).
