SERVICE & OPERATING MANUAL

Original Instructions

41-818830sm-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 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.

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 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.

The pump primes as a result of the suction stroke. The

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.

IMPORTANT

When the pumped product source is at a higher

level than the pump (ooded suction condition),

pipe the exhaust higher than the product source

to prevent siphoning spills. In the event of a

diaphragm failure a complete rebuild of the

center section is recommended.

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: Install 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.
