IMPORTANT
Read the safety warnings and instructions in this manual
before pump installation and start-up. Failure to comply with
the recommendations stated in this manual could damage the
pump and void factory warranty.
When used for toxic or aggressive uids, the pump should
always be ushed clean prior to disassembly.
Airborne particles and loud noise hazards. Wear eye and ear
protection.
Before maintenance or repair, shut off the compressed air line,
bleed the pressure, and disconnect the air line from the pump.
Be certain that approved eye protection and protective clothing
are worn at all times. Failure to follow these recommendations
may result in serious injury or death.
When the pump is used for materials that tend to settle out
or solidify, the pump should be ushed after each use to
prevent damage. In freezing temperatures the pump should be
completely drained between uses.
Before pump operation, inspect all fasteners for loosening
caused by gasket creep. Retighten loose fasteners to prevent
leakage. Follow recommended torques stated in this manual.
CAUTION
WARNING
Nonmetallic pumps and plastic components are not UV
stabilized. Ultraviolet radiation can damage these parts and
negatively affect material properties. Do not expose to UV light
for extended periods of time.
In the event of diaphragm rupture, pumped material may enter
the air end of the pump, and be discharged into the atmosphere.
If pumping a product that is hazardous or toxic, the air exhaust
must be piped to an appropriate area for safe containment.
This pump is pressurized internally with air pressure during
operation. Make certain that all fasteners are in good condition
and are reinstalled properly during reassembly.
Take action to prevent static sparking. Fire or explosion can
result, especially when handling ammable liquids. The pump,
piping, valves, containers and other miscellaneous equipment
must be properly grounded.
Safety Information
WARNING
Pump not designed, tested or certied to be powered by
compressed natural gas. Powering the pump with natural
gas will void the warranty.
Use safe practices when lifting

Air-Operated Double Diaphragm (AODD) pumps are powered
by compressed air or nitrogen.
The main directional (air) control valve ①distributes
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 ⑤connected 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ap)⑥orientation.
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uid
through the suction piping and across the suction side check
valveandintotheouteruid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.

Installation And Start-Up
Locatethepumpasclosetotheproductbeingpumpedaspossible.Keepthesuctionlinelengthandnumberofttingstoaminimum.Donotreducethesuctionline
diameter.
Air Supply
Connectthepumpairinlettoanairsupplywithsufcient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owasdesired.Ifopeningthevalve
increasescyclingrate,butdoesnotincreasetherateofow,cavitationhasoccurred.Thevalveshouldbeclosedslightlytoobtainthemostefcientairowtopump

Pump Inspection and Cleaning
The SP3A20NPT sanitary pump can be cleaned using several techniques. However, it is important
to follow guidelines set by the IAMFES, the USPHS, and the DIC and/or internal rules for inspection,
cleaning and sanitization.
If the pump is to be steam cleaned, disconnect the suction line from the pump. Connect the steam
line to the pump inlet. Maintain the ow of steam through the pump for at least ve minutes after the
temperature at the outlet has reached 200°F (94°C).
Hot water may also be used. Pump water that is maintained at minimum of 170°F (77°C) through the
pump for at least ve minutes. Please note that the maximum cleaning temperature of the pump is 220°
(104°C).
Chemical cleaning may also be used in sanitizing the pump. Be sure to consult your distributor or the
manufacturer to verify that the elastomer(s) used in the pump are compatible with the chemicals being
used in the cleaning process.
