CAUTION: Do not apply compressed air to the exhaust

CAUTION: Do not, under any circumstance loosen the set
screw located at the adjuster dial of the Pro-Flo X ™ pump.
If the set screw is loose when the pump is pressurized, it
could eject and cause injury to anyone in the area.
CAUTION : Do not over-lubricate air supply — excess
lubrication will reduce pump performance. Pump is pre-

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.

This is an example showing how to determine flow rate and

cy Management System (EMS) curve and the performance

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 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

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

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

(See figure 4.)
Step 3
: Determine flow X Factor. Divide the required

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.

: 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

In summary, for an application requiring 18.9 lpm

the pump inlet air pressure should be set to 4.1 bar

The end user did not require that much flow and wanted to reduce
air consumption at his facility. He determined that EMS setting 3
would meet his needs. At 3.5 bar (50 psig) discharge pressure and
EMS setting 3, the flow “X factor” is 0.87 and the air “X factor” is

can be used to optimize the performance of
your Wilden pump for specific applications.
The pump is delivered with the EMS adjusted
