Self‐primingpumpKSP.AvariantoftheZH‐3208pump.
ZH3208isanormalmulti‐stagecentrifugalpumpwithseveralimpellersthatcanachieve
highpressures.Severalimpellers,so‐calledstages,arebuiltinarowonashaft.Howeverasa
centrifugalpump,theZHisnotself‐primingandalsodoesnothavedryrunprotection.
ByintegratingasuctionstageinourZHpump,additionalpropertiessuchasself‐primingand
dryrunprotectionareachieved.ThenewKSPpumpcanthenprimeliquidsfromatankthat
ispositionedlowerandisnotdamagedbyabriefdryrun.
Function:Thepumpconsistsoftwopumptypesthataremountedonadriveshaft.
Amulti‐stagecentrifugalpumpcanthenonlyoperatewhentheinsideofthepumpisalways
filledwithliquid.Thisworksverywellwhenthepumphasaninfloworthesuctionlineis
alwayscompletelyfilled.Forexample,thisispossiblebyusingafootvalve.Ifthepumphasa
suctionliftinsteadofaninflowandnofootvalvecanbeused,thepumpwillquicklyrundry
andcanthennolongerconveyanyliquidorbuilduppressure.Hereitmustfirstbeensured
thattheliquidcompletelyfillsthepumpandthecompletesuctionlineagain.
Anintegratedsuctionstageisusedhere.Thisispositionedonthesameshaftafterthe
centrifugalpumpstages.Whenpriming,themediumfromthesuctiontankistransported
throughthesuctionlineinthepump,throughallpumpstagesofthecentrifugalpumpand
finallythroughthesuctionstage.Thisarrangementofthestagesensuresthatthestagesof
thecentrifugalpumpareslowlyfilleduntilthepumpisfullyfilledwithliquid.

Start‐up
Beforeinitialstart‐up,thepumpmustbefilledwithliquidonetimesothatthe
suctionstagecancreateavacuum.Duringsubsequentshutdown,enoughresidual
liquidalwaysremainsinthepumpsothatarestartcantakeplacewithoutrefilling.

Thecentrifugalpumpissealedwithamechanicalsealontheshaft.Thisdynamicseal
maynotrundryandmustalwaysbelubricatedwithliquid.Thissealwasplacedafter
thecentrifugalpumpstagesandafterthesuctionstage.Forthisarrangement,the
sealisalwaysprotectedagainstadryrunevenduringprimingwhenthereisvery
littleliquidinthepump.
Thesuctionline(max.3m)shouldbeasshortaspossibleandguidedvertically
(alwaysrising!)outofthesuctiontank.Thisisdecisiveforagoodsuctionfunctionof
thepump.Suctionliftsuptomax.2marepossible.
Whenpriming,airisfirstdrawnintotheinsideofthepump.Aventilationoption
mustbeprovided.Thepressurelinemustbeopen(withoutnon‐returnvalve)ora
smallventilationlineshouldbeinstalled.

Disassembly
Removalofthepump,drainingandpreparationfordisassemblyaredescribedinin
BA27224.
Startatthesuctionsidewhendismantlingthepump.Thesuctioncover(162)andthe
normalstages(147)withimpellers(233)areremovedasdescribedinBA27224.
Disassemblyofthesuctionstage;suctionstagePos.111isanassemblythatcanonly
becompletelyreplacedifrequired.Pleaseobservethesparepartsdrawing.
Afterremovingthesuctionstage(Pos.111),proceedfurtherasdescribedinBA
27224.

Reassembly
Assemblyisessentiallydisassemblyinthereverseorder.
Checkallpartsforwear.Damagedpartsmustalwaysbereplacedbynewones.
Mechanicalsealsandallothersealsarenotwear‐freeandshouldbecheckedfor
damage.

Useonlyoriginalsparepartsforrepairs!Duringreassemblyallsealsmustbe
replaced.

Observingtheseinstructionsisapreconditionforproblem‐freeoperationofthepumpand
forhonouringanywarrantyclaimsthatmaybesubmitted.
