PRINCIPLES OF OPERATION
The air-valve directs pressurized air behind the diaphragm on the right,
causing the diaphragm on the right to move outward (to the right).
Since both the right diaphragm and the left diaphragm are connected
via a diaphragm rod, when the right diaphragm moves to the right, the
left diaphragm (through the action of the diaphragm rod) moves to the
right also.
When the diaphragm on the left side is moving to the right, it is referred
to as suction stroke. When the left diaphragm is in its suction stroke,
the left suction ball moves upward (opens) and the left discharge ball
moves downward (closes). This action creates suction and draws liquid
into the left side chamber.
The air-valve directs pressurized air behind the left diaphragm, causing
the left diaphragm to move outward (to the left).
Since both the left diaphragm and the right diaphragm are connected
via a diaphragm rod, when the left diaphragm moves to the left, the
right diaphragm (through the action of the diaphragm rod) moves to
the left also.
When the diaphragm on the left side moves outward, the left discharge ball
moves upward (opens) and the left suction ball moves downward (closes).
This causes the liquid to leave the left side liquid outlet of the pump.
Simultaneously, the right diaphragm moves inward (to the left), which
causes the right suction ball to open and the right discharge to close,
which in turn causes suction, drawing liquid into the right chamber.
The process of alternating right suction / left discharge (and vice-versa)
continues as long as compressed air is supplied to the pump.

SECTION 6
INSTALLATION, TROUBLESHOOTING
AND MAINTENANCE
INSTALLATION
PIPING
Whenever possible ensure the pump is installed using
the shortest possible pipe lengths with the minimum
amount of pipe fittings. Ensure all piping is supported
independent of the pump.
Suction and discharge piping should not be smaller
than the connection size of the pump. When pumping
liquids of high viscosity, larger piping may be used, in
order to reduce frictional pipe loss.
Employ flexible hoses in order to eliminate the vibration
caused by the pump. Mounting feet can also be used to
reduce vibration effects.
All hoses should be reinforced, non-collapsible and be
capable of high vacuum service. Ensure that all piping
and hoses are chemically compatible with the process
and cleaning fluid.
For processes where pulsation effects should be
reduced, employ a pulsation dampener on the discharge
side of the pump.
For self-priming applications, ensure all connections
are airtight and the application is within the pumps
dry-lift capability. Refer to product specifications for
further details.
For flooded suction applications, install a gate valve
on the suction piping in order to facilitate service.
For unattended flooded suction operation, it is
recommended to pipe the exhaust air above the liquid
source. In the event of a diaphragm failure this will
reduce or eliminate the possibility of liquid discharging
through the exhaust onto the ground.
LOCATION
Ensure that the pump is installed in an accessible
location, in order to facilitate future service and
maintenance.
AIR
Ensure that the air supply is sufficient for the
volume of air required by the pump. Refer to product
specifications for further details. For reliable
operation, install a 5 micron air filter, air-valve and
pressure regulator. Do not exceed the pumps
maximum operating pressure of 120 psig.
REMOTE OPERATION
Utilize a three way solenoid valve for remote
operation. This ensures that air between the solenoid
and the pump is allowed to “bleed off,” ensuring
reliable operation. Liquid transfer volume is estimated
by multiplying displacement per stroke times the
number of strokes per minute
NOISE
Correct installation of the muffler reduces sound
levels. Refer to product specifications for
further details.
SUBMERGED OPERATION
For submersible operation, pipe the air exhaust to
atmosphere
GROUNDING THE PUMP
Loosen grounding screw and install a grounding wire.
Tighten grounding screw. Wire size should be a 12
gauge wire or larger. Connect the other end of the wire
to a true earth ground. Equipment must be grounded
to achieve ATEX rating and it is recommended to
configure the pump with a grounding lug option.

ALF-11060-E-02 All-Flo11
OPERATION
The Air-Operated Double Diaphragm Pump requires
a minimum of 20 psig of air to operate, with some
variation according to diaphragm material. Increasing
the air pressure results in a more rapid cycling of the
pump and thus a higher liquid flow rate. In order to not
exceed 120 psig of inlet air pressure, and for accurate
control of the pump, it is suggested to use a pressure
regulator on the air inlet.
An alternate means of controlling the flow-rate of the
pump is to use an inlet air valve and partially open or
close accordingly. When the air valve is completely in
the closed position, the pump will cease to operate.
A third method of controlling the flow rate of the
pump is to use a liquid discharge valve. Closing the
liquid discharge valve will cause a decrease in the
flow rate since the pump will operate against a higher
discharge pressure.
Solenoid control of the inlet air may also be used in
order to facilitate remote operation. A three way
solenoid valve is recommended, in order to allow the
air to “bleed off” between the solenoid and the pump.
Do not use valves for flow control on the suction side
of the pump. (Closing or partially closing a liquid
suction valve restrict the suction line and may cause
damage to the diaphragms.) Suction strainers may
be employed to reduce or eliminate larger solids, but
routine maintenance is necessary in order to prevent
a restriction on the suction.
MAINTENANCE
Due to the unique nature of each application, periodic
inspection of the pump is the best method to determine
a proper maintenance schedule. A record should be
kept of all repairs made to an installed pump. This will
serve as the best predictor of future maintenance.
Typical maintenance involves replacing of “wear-
parts” such as the diaphragms, balls, valve seats and
O-rings. Proper maintenance can ensure trouble-free
operation of the pump. Refer to repair and assembly
instructions for further details.
WARNING Maintenance must not be performed
when a hazardous atmosphere is present.
MAINTENANCE SCHEDULE
WEEKLY (OR DAILY)
Make a visual check of the pump. If pumped fluid is
leaking out of the pump, pipe fittings or muffler turn
off pump and schedule maintenance.
EVERY THREE MONTHS
Inspect fasteners and tighten any loose fasteners to
recommended torque settings.
Schedule pump service based on pump’s service
history.
