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 (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: 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 wetted 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: 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 Teflon®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 Teflon®-fitted pumps come standard
from the factory with expanded Teflon®gaskets
installed in the diaphragm bead of the liquid chamber.
Teflon®gaskets cannot be re-used.
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 also
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 removes 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 diaphragm,
diaphragm A, reaches the limit of itsdischarge
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.
