SERVICE & OPERATING MANUAL
Original Instructions

s05mdl1sm-rev1113
www.sandpiperpump.com
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.

Optional 8 foot long (244 centimeters) Ground Strap is available for easy ground connection.
To reduce the risk of static electrical sparking, this pump must be grounded. Check the local
electrical code for detailed grounding instruction and the type of equipment required.
Refer to nomenclature page for ordering information.
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.

Air-OperatedDoubleDiaphragm(AODD)pumpsarepowered
by compressed air, nitrogen or natural gas.
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exceedsliquidchamber
pressure , 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 increasing
the chamber volume. This results in a pressure differential
necessary for atmospheric pressure 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.

diaphragm failure a complete rebuild of the
center section is recommended.
