NOTE: Not all materials are available for all models. See "Wilden Pump
Designation System " on page 5 for material options for your pump.
CAUTION: When choosing pump materials, be sure to
check the temperature limits for all wetted components.
Example: FKM 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.
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: Tighten clamp bands and retainers prior to
installation. Fittings may loosen during transportation.
NOTE: When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure tight fit.
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 air supply.
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.

WILDEN PUMP DESIGNATION SYSTEM

WIL-10252-E-01 Wilden®
6
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.
FIGURE1 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
pressurizedairto theback 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
tothe hydraulic forcesdeveloped in the liquid
chamber and manifold of the pump. These
same hydraulic forces liftthe 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.Theinletvalveballisforcedoffitsseat
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 CURVES
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.
