SERVICE & OPERATING MANUALOriginal Instructions

41-818820.22.23sm-rev0812

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 fluids, the pump should always be flushed 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.

To be fully groundable, the pumps must be ATEX Compliant. Refer to the nomenclature page for ordering information.

Optional Ground Strap(0114-014178) 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 flushed 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 flammable liquids. The pump, piping, valves, containers and other miscellaneous equipment must be properly grounded.

Safety Information

Grounding the Pump

WARNINGTake action to prevent static sparking. Fire or explosion can result, especially when handling flammable liquids. The pump, piping, valves, containers or other miscellaneous equipment must be grounded.

Air-OperatedDoubleDiaphragm(AODD)pumpsarepoweredby compressed air.

The main directional (air) control valve ① distributes compressedairtoanairchamber,exertinguniformpressureover the inner surface of the diaphragm ②.Atthesametime,theexhaustingair③ from behind the opposite diaphragm isdirectedthroughtheairvalveassembly(s)toanexhaust port ④.

Asinnerchamberpressure(P1)exceedsliquidchamberpressure (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 arecontrolledbythecheckvalves(ballorflap)⑥ orientation.

The pump primes as a result of the suction stroke. The suctionstrokelowersthechamberpressure(P3) increasing the chamber volume. This results in a pressure differential necessary for atmospheric pressure (P4)topushthefluidthrough the suction piping and across the suction side check valveandintotheouterfluidchamber⑦.

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.Thediaphragm’sinnerplatemakescontactwithanactuator 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.

Step 1: With manifolds and outer chambersremoved, remove diaphragm assemblies from diaphragm rod. DO NOTuseapipewrenchorsimilartooltoremoveassemblyfromrod.Flawsintherodsurfacemaydamagebearingsandseal.Soft jawsin a vise are recommended to prevent diaphragm rod damage.

Step 1.A: NOTE: Not all inner diaphragm plates are threaded.Somemodels utilize a throughholeintheinnerdiaphragmplate.Ifrequiredtoseparatediaphragm assembly, place assembly in a vise, gripping on theexterior cast diameter of the innerplate.Turntheouterplateclockwisetoseparatetheassembly.

Always inspect diaphragms for wear cracks orchemicalattack. Inspect innerandouterplates fordeformities,rustscaleandwear.Inspectintermediatebearingsforelongationandwear.Inspectdiaphragmrodforwearormarks.Clean or repair if appropriate. Replace as required.

Step 2: Reassembly:TherearetwodifferenttypesofdiaphragmplateassembliesutilizedthroughouttheSandpiperproductline:Outerplatewithathreadedstud, diaphragm, and a threaded inner plate.

Outer platewith a threaded stud, diaphragm, andan inner platewith throughhole.Secure threadedinnerplateinavise.Ensurethattheplatesarebeinginstalledwiththeouterradiusagainstthediaphragm.

Step 3:Lightlylubricate,withacompatiblematerial,the inner faces of both outer and inner diaphragm plates whenusingonnonOverlaydiaphragms(ForEPDMwater isrecommended).No lubrication isrequired.

Step 4: Push the threaded outer diaphragmplate through the center hole of the diaphragm. Note: Most diaphragms are installed with thenatural 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 torquewrench to tighten the assembly together.Torquevaluesarecalledoutontheexplodedview.

Repeat procedure for second side assembly. Allow aminimum of 15minutes to elapse aftertorquing, then re-torque the assembly to compensate for stress relaxation in the clamped assembly.

Step 6: Thread one assembly onto the diaphragm rodwithsealingwasher (whenused)andbumper.

Step 7: Instal l diaphragm rod assemblyinto pump and secure by installing the outer chamber in place and tightening the capscrews. Step 8: On opposite side of pump, thread the remainingassemblyontothediaphragmrod.Usingatorquewrench,tightentheassemblytothediaphragmrod.Aligndiaphragmthroughboltholes,alwaysgoingforwardpasttherecommendedtorque.Torquevaluesarecalledoutontheexplodedview.NEVER reverse to align holes, if alignment cannot be achieved without damage to diaphragm, loosen completeassemblies, rotate diaphragm and reassemble as described above.
