CAUTION: Do not over-lubricate air supply —
excess lubrication will reduce pump performance.

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 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 signifi cantly 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, fi re or explosion could
result.
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 fl uid
to fl ow 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 fi lter. A 5µ (micron)
air fi lter is recommended.
CAUTION: If the pipe plug in the inlet or discharge
manifold on the 51 mm (2") Advanced™ plastic
center-ported model is removed, a triple density
(red) PTFE pipe tape is recommended to ensure
adequate sealing.
NOTE: When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(t ur ning in oppo site direc tions) to ensure tight fi t.
(See torque specifi cations in Section 7.)
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.
CAUTION: Tighten all hardware prior to installation.
CAUTION: Do not exceed 8.6 bar (125 psig) air
supply pressure.
CAUTION: The process fl uid and cleaning fl uids
must be chemically compatible with all wetted
pump components. Consult Chemical Resistance
Guide (E4).
CAUTION: Do not exceed 82°C (180°F) air inlet
temperature for Pro-Flo X™ models.

HOW IT WORKS—PUMP
The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show fl ow pattern
through the pump upon its initial stroke. It is assumed the pump has no fl uid in it prior to its initial stroke.
FIGURE 1 The air valve dir ects 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 shaf t
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 fl uid into
the inlet manifold forcing the inlet valve
ball off its seat. Liquid is free to move
past the inlet valve ball and fi ll the liquid
chamber (see shaded area).
HOW IT WORKS—AIR DISTRIBUTION SYSTEM
FIGURE 2 When the pressurized diaphragm,
diaphra gm A, re aches t he limit of it s disc harge
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 fl uid to fl ow 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 fl uid into the inlet
manifold of the pump. The inlet valve ball
is forced off its seat allowing the fl uid being
pumped to fi ll the liquid chamber.
FIGURE 3 At completion of the stroke,
the air valve again redirects air to the
back side of diaphragm A, which star ts
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
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.

and 85 Nm3/h (50 scfm) air consumption.
(See dot on chart.)
Caution: Do not exceed 8.6 bar (125 psig)
air supply pressure.

Flow rates indicated on chart were determined by pumping water.
For optimum life and performance, pumps should be specifi ed so that daily operation
parameters will fall in the center of the pump performance curve.

Pro-Flo X
The Pro-Flo X™ air distribution system with the
revolutionary Effi ciency Management System (EMS)
offers fl exibility 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
TM
Operating Principal
control dial, the operator can select the optimal
balance of fl ow and effi ciency that best meets the
application needs. Pro-Flo X™ provides higher
performance, lower
operational costs
and fl exibility that
exceeds previous
industry standards.

Pro-Flo X™ pumps
are shipped from
the factory on
setting 4, which
is the highest
fl ow rate setting
possible
Moving the dial
from setting 4
causes a decrease
in fl ow and an even
greater decrease in
air consumption.
When the air

decreases more
than the fl ow

is improved and

This is an example showing how to determine fl ow rate and
air consumption for your Pro-Flo X™ pump using the Effi ciency 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 fl ow 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 fl ow curve,
draw a vertical line downward until reaching
the bottom scale on the chart. Identify the fl ow
rate (in this case, 8.2 gpm). Observe location
of performance point relative to air consumption curves and approximate air consumption
value (in this case, 9.8 scfm).

GPM
curve, draw vertical lines downward until
reaching the bottom scale on the chart. This
identifi es the fl ow 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 fl ow rate (8.2 gpm)
obtained in Step 1 by the fl ow X Factor multiplier (0.58) in Step 2 to determine the fl ow rate
at EMS setting 2. Multiply the air consumption (9.8 scfm) obtained in Step 1 by the air
X Factor multiplier (0.48) in Step 2 to determine the air consumption at EMS setting 2
(Figure 3).

Step 2:
Determining flow and air X Factors. Locate
your discharge pressure (40 psig) on the vertical axis of the EMS curve (Figure 2). Follow
along the 2.8 bar (40 psig) horizontal line until
intersecting both fl ow and air curves for your
desired EMS setting (in this case, setting 2).
Mark the points where the EMS curves intersect the horizontal discharge pressure line.
