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 Chemical
Resistance Guide (E4) for chemical compatibility
and temperature limits.
WARNING: Prevention of 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 wetted
pump components (see 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: 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 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 submersible and non-submersible
options. Do not use non-submersible Pro-Flo X™
models in submersible applications. Turbo-Flo®
pumps can be used in submersible applications.
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.
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 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).
FIGURE 2 When the pressurized dia-
phragm , 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
while pulling diaphragm A to the center.
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 of the pump creates a
vacuum within liquid chamber A. Atmos-
pheric 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.
The Pro-Flo®patented air distribution system incorporates two
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 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.

PX1500 PERFORMANCE

The Pro-Flo X™ air distribution system with the
revolutionary Efficiency Management System (EMS)
offers flexibility never before seen in the world of
AODD pumps. The
patent-pending EMS
is simple and easy
to use. With the
turn of an integrated
control dial, the operator can select the optimal
balance of flow and efficiency that best meets the
application needs. Pro-Flo X™ provides higher
performance, lower
operational costs
and flexibility that
exceeds previous
industry standards.
Pro-Flo XTM Operating Principle
Section 5
Turning the dial
changes the
relationship
between air inlet
and exhaust
porting.
Each dial setting
represents an
entirely different
flow curve
Pro-Flo X™ pumps
are shipped from
the factory on
setting 4, which
is the highest
flow rate setting
possible
Moving the dial
from setting 4
causes a decrease
in flow and an even
greater decrease in
air consumption.
When the air
consumption
decreases more
than the flow
rate, efficiency
is improved and
operating costs
are reduced.

This is an example showing how to determine flow rate and
air consumption for your Pro-Flo X™ pump using the Efficien-
cy Management System (EMS) curve and the performance
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 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
rate (in this case, 8.2 gpm). Observe location
of performance point relative to air consump-
tion curves and approximate air consumption
value (in this case, 9.8 scfm).
Step 2: Determining flow and air X Factors. Locate
your discharge pressure (40 psig) on the verti-
cal axis of the EMS curve (Figure 2). Follow
along the 2.8 bar (40 psig) horizontal line until
intersecting both flow and air curves for your
desired EMS setting (in this case, setting 2).
Mark the points where the EMS curves inter-
sect the horizontal discharge pressure line.
After locating your EMS points on the EMS
curve, draw vertical lines downward until
reaching the bottom scale on the chart. This
identifies the flow X Factor (in this case, 0.58)
and air X Factor (in this case, 0.48).
Step 3: Calculating performance for specific EMS
setting. Multiply the flow rate (8.2 gpm)
obtained in Step 1 by the flow X Factor multi-
plier (0.58) in Step 2 to determine the flow rate
at EMS setting 2. Multiply the air consump-
tion (9.8 scfm) obtained in Step 1 by the air
X Factor multiplier (0.48) in Step 2 to deter-
mine the air consumption at EMS setting 2
(Figure 3).
Figure 3
The flow rate and air consumption at Setting
2 are found to be 18.2 lpm (4.8 gpm) and 7.9
Nm3/h (4.7 scfm) respectively.

EMS CURVE
SETTING 4 PERFORMANCE CURVE
This is an example showing how to determine the inlet air
pressure and the EMS setting for your Pro-Flo X™ pump to
optimize the pump for a specific application. For this exam-
ple we will be using an application requirement of 18.9 lpm
(5 gpm) flow rate against 2.8 bar (40 psig) discharge pressure.
This example will illustrate how to calculate the air consump-
tion that could be expected at this operational point.
Step 1 : Establish inlet air pressure. Higher air pres-
sures will typically allow the pump to run
more efficiently, however, available plant air
pressure can vary greatly. If an operating
pressure of 6.9 bar (100 psig) is chosen when
plant air frequently dips to 6.2 bar (90 psig)
pump performance will vary. Choose an oper-
ating pressure that is within your compressed
air system's capabilities. For this example we
will choose 4.1 bar (60 psig).
Step 2 : Determine performance point at setting 4. For
this example an inlet air pressure of 4.1 bar
(60 psig) inlet air pressure has been chosen.
Locate the curve that represents the perfor-
mance of the pump with 4.1 bar (60 psig) inlet
air pressure. Mark the point where this curve
crosses the horizontal line representing 2.8
bar (40 psig) discharge pressure. After locat-
ing this point on the flow curve, draw a verti-
cal line downward until reaching the bottom
scale on the chart and identify the flow rate.
In our example it is 38.6 lpm (10.2 gpm). This
is the setting 4 flow rate. Observe the loca-
tion of the performance point relative to air
consumption curves and approximate air
consumption value. In our example setting
4 air consumption is 24 Nm3/h (14 scfm).
See figure 4.
Step 3 : Determine flow X Factor. Divide the required
flow rate 18.9 lpm (5 gpm) by the setting 4 flow
rate 38.6 lpm (10.2 gpm) to determine the flow
X Factor for the application.
Step 4 : Determine EMS setting from the flow
X Factor. Plot the point representing the flow
X Factor (0.49) and the application discharge
pressure 2.8 bar (40 psig) on the EMS curve.
This is done by following the horizontal 2.8
bar (40 psig) psig discharge pressure line until
it crosses the vertical 0.49 X Factor line. Typi-
cally, this point lies between two flow EMS
setting curves (in this case, the point lies be-
tween the flow curves for EMS setting 1 and
2). Observe the location of the point relative
to the two curves it lies between and approxi-
mate the EMS setting (figure 5). For more pre-
cise results you can mathematically interpo-
late between the two curves to determine the
optimal EMS setting.
5 gpm / 10.2 gpm = 0.49 (flow X Factor)

Example 2.2
Determine air consumption at a specific
EMS setting.
Step 1 : Determine air X Factor. In order to determine
the air X Factor, identify the two air EMS set-
ting curves closest to the EMS setting estab-
lished in example 2.1 (in this case, the point lies
between the air curves for EMS setting 1 and
2). The point representing your EMS setting
(1.8) must be approximated and plotted on the
EMS curve along the horizontal line represent-
ing your discharge pressure (in this case, 40
psig). This air point is different than the flow
point plotted in example 2.1. After estimating
(or interpolating) this point on the curve, draw
a vertical line downward until reaching the
bottom scale on the chart and identify the air
X Factor (figure 7).
Step 2 : Determine air consumption. Multiply your
setting 4 air consumption (14 scfm) value by
the air X Factor obtained above (0.40) to deter-
mine your actual air consumption.
In summary, for an application requiring 18.9 lpm
(5 gpm) against 2.8 bar (40 psig) discharge pressure,
the pump inlet air pressure should be set to 4.1 bar
(60 psig) and the EMS dial should be set to 1.8. The
pump would then consume 9.5 Nm3/h (5.6 scfm) of
compressed air.

The Efficiency Management System (EMS) can be used to optimize the performance of your Wilden pump for specific applications. The pump is delivered with the EMS adjusted to setting 4, which allows maximum flow. The EMS curve allows the pump user to deter- mine flow and air consumption at each EMS setting. For any EMS setting and discharge pressure, the “X factor” is used as a multi- plier with the original values from the setting 4 performance curve to calculate the actual flow and air consumption values for that spe- cific EMS setting. Note: you can interpolate between the setting curves for operation at intermediate EMS settings.
EXAMPLE A PX1500 aluminum, Rubber-fitted pump operating at EMS setting 4, achieved a flow rate of 640 lpm (169 gpm) using 192 Nm3/h (113 scfm)
of air when run at 5.5 bar (80 psig) air inlet pressure and 2.1 bar (30 psig) discharge pressure (See dot on performance curve). The end user did not require that much flow and wanted to reduce air consumption at his facility. He determined that EMS setting 2 would meet his needs. At 2.1 bar (30 psig) discharge pressure and EMS setting 2, the flow “X factor” is 0.67 and the air “X factor” is 0.52 (see dots on EMS curve). Multiplying the original setting 4 values by the “X factors” provides the setting 2 flow rate of 429 lpm (113 gpm) and an air consumption of 100 Nm3/h (59 scfm). The flow rate was reduced by 33% while
the air consumption was reduced by 48%, thus providing increased efficiency. For a detailed example for how to set your EMS, see beginning of performance curve section. Caution: Do not exceed 8.6 bar (125 psig) air supply pressure.
