Fluoro-Seal™ –40°C to 232°C –40°F to 450°F
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 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] on 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: When installing PTFE diaphragms, it is important to tighten outer pistons simultaneously (turning in
opposite directions) to ensure tight fit.
WARNING: Tighten all clamp bands and retainers prior
to installation. Fittings may loosen during transportation.
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 (see E4).
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.
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: UL-listed pumps must not exceed 3.4 bar
(50 psig) air supply pressure.
CAUTION: Only explosion proof (NEMA 7) solenoid
valves should be used in areas where explosion proof
equipment is required.
CAUTION: Do not hang Stallion models by their
handles.

HOW IT WORKS—PUMP
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 stress
from the diaphragm. The compressed
air 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).
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 CURVE
T15 METAL
SUCTION LIFT CAPABILITY
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.
