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.
