Air-Operated Double Diaphragm (AODD) pumps are powered
by compressed air.
The main directional (air) control valve ① distributes
compressed air to an air chamber, exerting uniform pressure
over the inner surface of the diaphragm ②. At the same time,
the exhausting air ③ from behind the opposite diaphragm
is directed through the air valve assembly(s) to an exhaust
port ④.
As inner chamber pressure (P1) exceeds liquid chamber
pressure (P2), the rod ⑤ connected diaphragms shift
together creating discharge on one side and suction on the
opposite side. The discharged and primed liquid’s directions
are controlled by the check valves (ball or flap)⑥ orientation.
The pump primes as a result of the suction stroke. The
suction stroke lowers the chamber pressure (P3) increasing
the chamber volume. This results in a pressure differential
necessary for atmospheric pressure (P4) to push the fluid
through the suction piping and across the suction side check
valve and into the outer fluid chamber ⑦.
Suction (side) stroking also initiates the reciprocating
(shifting, stroking or cycling) action of the pump. The suction
diaphragm’s movement is mechanically pulled through its
stroke. The diaphragm’s inner plate makes contact with an
actuator plunger aligned to shift the pilot signaling valve.
Once actuated, the pilot valve sends a pressure signal to the
opposite end of the main directional air valve, redirecting the
compressed air to the opposite inner chamber.

Principle of Pump Operation
Installation And Start-Up
Locate the pump as close to the product being pumped as possible. Keep the suction line length and number of fittings to a minimum. Do not reduce the suction line
diameter.
Air Supply
Connect the pump air inlet to an air supply with sufficient capacity and pressure to achieve desired performance. A pressure regulating valve should be installed to
insure air supply pressure does not exceed recommended limits.
Air Valve Lubrication
The air distribution system is designed to operate WITHOUT lubrication. This is the standard mode of operation. If lubrication is desired, install an air line lubricator
set to deliver one drop of SAE 10 non-detergent oil for every 20 SCFM (9.4 liters/sec.) of air the pump consumes. Consult the Performance Curve to determine air
consumption.
Air Line Moisture
Water in the compressed air supply may cause icing or freezing of the exhaust air, causing the pump to cycle erratically or stop operating. Water in the air supply can
be reduced by using a point-of-use air dryer.
Air Inlet And Priming
To start the pump, slightly open the air shut-off valve. After the pump primes, the air valve can be opened to increase air flow as desired. If opening the valve
increases cycling rate, but does not increase the rate of flow, cavitation has occurred. The valve should be closed slightly to obtain the most efficient air flow to pump
flow ratio.

Troubleshooting Guide
Symptom: Potential Cause(s): Recommendation(s):
Pump Cycles Once Deadhead (system pressure meets or exceeds air
supply pressure).
Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero flow.
(Does not apply to high pressure 2:1 units).
Air valve or intermediate gaskets installed incorrectly. Install gaskets with holes properly aligned.
Bent or missing actuator plunger. Remove pilot valve and inspect actuator plungers.
Pump Will Not Operate
/ Cycle
Pump is over lubricated. Set lubricator on lowest possible setting or remove. Units are designed for lube free operation.
Lack of air (line size, PSI, CFM). Check the air line size and length, compressor capacity (HP vs. CFM required).
Check air distribution system. Disassemble and inspect main air distribution valve, pilot valve and pilot valve actuators.
Discharge line is blocked or clogged manifolds. Check for inadvertently closed discharge line valves. Clean discharge manifolds/piping.
Deadhead (system pressure meets or exceeds air
supply pressure).

Step 1: With manifolds and outer chambers
removed, remove diaphragm assemblies from
diaphragm rod. DO NOT use a pipe wrench or similar
tool to remove assembly from rod. Flaws in the rod
surface may damage bearings and seal. Soft jaws
in a vise are recommended to prevent diaphragm
rod damage.
Step 1.A: NOTE: Not all inner diaphragm plates
are threaded. Some models utilize a through hole
in the inner diaphragm plate. If required to separate
diaphragm assembly, place assembly in a vise,
gripping on the exterior cast diameter of the inner
plate. Turn the outer plate clockwise to separate the
assembly.
Always inspect diaphragms for wear cracks or
chemical attack. Inspect inner and outer plates for
deformities, rust scale and wear. Inspect intermediate
bearings for elongation and wear. Inspect diaphragm
rod for wear or marks.
Clean or repair if appropriate. Replace as required.
Step 2: Reassembly: There are two different types
of diaphragm plate assemblies utilized throughout the
Sandpiper product line: Outer plate with a threaded
stud, diaphragm, and a threaded inner plate.
Outer plate with a threaded stud, diaphragm, and
an inner plate with through hole. Secure threaded
inner plate in a vise. Ensure that the plates are being
installed with the outer radius against the diaphragm.
Step 3: Lightly lubricate, with a compatible material,
the inner faces of both outer and inner diaphragm plates
when using on non Overlay diaphragms (For EPDM
water is recommended). No lubrication is required.
Step 4: Push the threaded outer diaphragm
plate through the center hole of the diaphragm.
Note: Most diaphragms are installed with the
natural bulge out towards the fluid side. S05,
S07, and S10 non–metallic units are installed
with the natural bulge in towards the air side.
Step 5: Thread or place, outer plate stud into
the inner plate. For threaded inner plates, use a
torque wrench to tighten the assembly together.
Torque values are called out on the exploded view.
Repeat procedure for second side assembly.
Allow a minimum of 15 minutes to elapse after
torquing, then re-torque the assembly to compensate
for stress relaxation in the clamped assembly.
Step 6: Thread one assembly onto the diaphragm
rod with sealing washer (when used) and bumper.
Step 7: Instal l diaphragm rod assembly
into pump and secure by installing the outer
chamber in place and tightening the capscrews.
Step 8: On opposite side of pump, thread the
remaining assembly onto the diaphragm rod. Using a
torque wrench, tighten the assembly to the diaphragm
rod. Align diaphragm through bolt holes, always going
forward past the recommended torque. Torque values
are called out on the exploded view. NEVER reverse
to align holes, if alignment cannot be achieved
without damage to diaphragm, loosen complete
assemblies, rotate diaphragm and reassemble as
described above.
