3. Warnings

1. Readthroughtheinstructionsbeforeinstallingthepumpand

startingitup.Ifindoubt,contactyourlocalSPXFlowTechnology

representative.

2. Checkthatthespecicationsofthemotorandmotorcontrolunitare

correct.Thisappliesinparticulartoapplicationswhichcarryariskof

explosion.

3. Observethatapumpmaybeunstableandmaytilttotheforeontoits

inlet port when having a relatively small motor and being assembled

onbracketsinsteadofbeingequippedwithaframewithadjustable

feet.Becarefulduringtheinstallationofsuchapump.(Forthis

reason, the W+50/600 pump is equipped with an anti-tilting unit.)

4. Donotstartthepumpbeforeallpipeconnectionshavebeentted

carefullyandtightened.Specialprecautionsmustbetakenwhen

thepumpisusedtopumphotand/orhazardousliquids.Insuch

casesfollowthelocalregulationsforpersonalsafetywhenworking

withtheseproducts.

5. Donotstartthepumpbeforethemotorshroudorshaftguardhasbeen

securelytted.

6. Thepumpcontainsrotatingparts.Neverputyourhands,ngersor

objectsintoapumpwhileitisinoperation.

7. Nevertouchtheshroudduringoperation,asitcanbecomeveryhot.

8. Nevertouchthepumpbodyduringoperationifthepumpisbeingused

forhotmedia,asthereisariskofbeingburnt.

9. Ifthepumpisoperatingwithliquidmediabuthasnocirculation,the

liquidwillheatupandmayturnintovapour,whichcouldcausean

explosion.

10. Alwaysremoveallassemblyandauxiliarytoolsfromthepumpbefore

starting it up.

11. Neverhosedownorcleantheelectricmotordirectlywithwater

orcleaninguid.

12. Neverliftthepumpattheshroud,asitisnotdesignedtocarrythe

weightofthemotor.Removetheshroudbeforeliftingthepump.

Alwaysusesecurelyttedliftingstrapswhenliftingwithacrane

orsimilarliftinggear.

13. Neverdismantlethepumpbeforethemotorhasbeendisconnected

fromthepowersupply.Removethefusesanddisconnectthecable

fromthemotorterminalbox.

14. Theinstallationofallelectricalpartsmustbecarriedoutbyqualied

personnel.

15. Neverdismantlethepumpuntilthepipesystemhasbeen

drained.Rememberthatliquidwillalwayscollectinthepump

body.Ifthepumpistobeusedforhotand/orhazardousliquids,

specialprecautionsmustbetaken.Insuchcasesfollowthelocal

regulationsforpersonalsafetywhenworkingwiththeseproducts.

16. Thefollowingvaluesspeciedforthepermissiblepressure

mustnotbeexceeded:

Max. 18 bar W+10/8, W+22/20, W+30/80, W+35/55, W+35/35,

W+110/130

5. Installation of pump

5.1 Positioning

Thefollowingmustbeobserved:

Thepumpmustbepositionedsothatthesuctionpipeisasshortas

possibleandthereisaslopinggradienttowardsthesuctionportof

the pump.

Keepthenumberofvalves,bendsandtee-piecesonthesuction

side to an absolute minimum.

Theremustbesufcientspacearoundthepumpforpipingand

accessformaintenance.

5.2 Lining up the pipe system

Ensure that the pipe system is adequately underpinned with pipe

supportssothatthepumpbodyisnotsubjecttostrainfromorthe

weightofthepipesystem.

Caution! Duringthesuctionprocess,thepumpmaytend

tovibrate.Apipesupportshouldbeplacedclose

tothepumpsuctiontopreventpipeworkvibration

creatingexcessivenoise.

5.3 Power supply

Themotormustbeconnectedviaacontrolcabinettothenetworkin

compliancewiththelocalregulations.Moreover,themotormustbe

connectedinaccordancewiththeinstructionsindicatedintheinner

sideoftheconnectingboxlidofthemotor.

Themotorshouldbeconnectedinsuchawaythatthemotorand

thereforetheimpellerareanti-clockwisewhenviewedfromthefront

inthedirectionofthesuctionportofthepumpbody.(Fig.4).

5.4 Liquid supply for flushed shaft seal

PumpswithaushedshaftsealarettedwithtwoPTFEhose

connectorsonthesealingange.Thehoseconnectorsare1/8inch

andt6.0mmhoses.Therequiredowquantityamountsto15–30l/h.

The maximum permissible pressure is 7 bar.

Thehoseconnectionshouldalwaysbepositionedverticallywith

theuidinletbelowandtheoutletabove(Fig.5).

Fluidconsumptioncanbelimitedbyinstallingasolenoidvalveon

thesupplyside.Theopen/closefunctionofthesolenoidvalvecan

becontrolledbythepump'sstart/stopsequence.

Donotusesteamorsteamcondensateontheconnectionfor

ushingliquids.Ifyouwishtousesteamasasealant,aspecial

asepticpipeconnectormustbeused.

Forconnectorssee5.5.

5.5 Connecting steam and steam condensate for aseptic use

Whenstaticdoublesealsareused,theconnectionforsteamor

steamcondensateatthepumpbodyisprovidedwithttingsfor

8 mm stainless steel pipes.

Steamofupto150°Cand5barcanbeused.

6. Start-up and operation

Beforestartingthepump,dismantleandcleanthesuctionpipe.

Anyforeignmaterialinthepumpshouldberemoved.

6.1 Checking the pump for foreign material

Removethepumpbodyasdescribedbelow.Thesectionaldrawing

(page3)istobeusedforreferencepurposes.

1. Disconnectthepowersupply.

2. Removethepumpbody(items1a,1b)byunscrewingtheclampring

(item9a)orbodyscrews,andcarefullyextractfromthebody.

3. Turntheimpeller(item4)toensurethatthereisnoforeignmaterial

behind it.

4. Removeanyforeignmaterialfrominsidethepump.

5. Whenthepumpbodyiscleanandfreeofforeignmaterial,reassemble

the pump.

Mountthepumpbodyasdescribedbelow:

6. Checkthatthelocatingpin(item8),whichisinstalledinthetopofthe

backplate,tswiththedetentinthepumpbodyandcarefully(to

avoiddamagetotheO-ring)pressthepumpbody(item1a,1b)

insoitcoverstheO-ring(item6).Thenfastenwiththeclampring

(item9a)orbodyscrewsandapplythecorrecttighteningtorque.

M10: max.35Nm(25ft-lb)

7. Checkthatthepipeunionshavebeentightenedproperlyandthatthe

pipesupportshavebeentted.

Tofacilitatethettingofthefrontcoverandpumphousing,we

recommendthattheO-ringislubricatedwithathinlayeroffood-

friendly,acid-freegreaseorsoap.
