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.

6.1 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-

6. Start-up and operation
6.2 Checking the pump
Tocheckthatthepumpisworkingsatisfactorily,pourwaterinto
thepumpandstartitmomentarily.Checkthedirectionofrotation.
Fig.6.Listenforanyunusualnoises.
Inpumpswithwater-ushedorsteam-ushedshaftseals,theseal
chambermustbelledwithwater/steam.
Caution! Neverallowthepumptorunwithoutliquid,asthis
willruintheshaftseal.
6.3 Starting the pump
Checkthefollowingbeforestartingthepump:
- Thattheshaftguardhasbeenttedproperly.
- Thatthereisunobstructedaccessforliquidandthatthepumpis
primed.
- Thatthevalveonthedischargesideisclosed.
Thevalveonthedischargesideisclosedduringstart-uptoprevent
themotorfromoverloading,butshouldbeopenedagainassoonas
the pump has been started.
Note! Thepumpshouldnotbeleftrunningtoolongwithoutpumping
(typically15minutesifthepumpedliquidisnot
hot),becauseitwillgetwarmandthepriming
liquid will evaporate.
6.4 Flushing liquid
Inpumpswithaushedshaftseal,checkthatthesupplyinletfor
theushingmediumisopenandthattheowofthemediumis
