TheALMATECMaschinenbauGmbHiscertifiedasamodern,quality‐orientatedenterpriseaccordingto
DINENISO9001:2008and14001:2009.Beforereleasefordispatch,anypumphastoundergoanextendedfinal


AsageneralruleinthecountriesoftheEUonlysuchmachinesareallowedtotakeintooperation,whichare
determinedtomeettheregulationsoftheEUmachinerydirective,theharmonizedstandards,Europeanstandards
andtherespectivenationalstandards.HencetheoperatorhastoverifywhethertheALMATECpumpmanufactured
anddeliveredproperlyaccordingtothecustomer’sordermeetsthementionedrequirements.

Thereforemakesure,beforeputtingthepumpintooperation,thatthepumpandtheusedmaterialsofconstruction
aresuitablefortheprovidedapplicationandtheinstallationsite.Tocheckthis,theexactpumpcodeisrequired.This
code,theserialnumberandtheyearofconstructionarenotedontheidentificationplatesonthepumpitself.

Whenusingnon‐conductivediaphragmmaterials,thefollowingexemplaryprotectionmeasureshavetobe
respected:
‐Thepumpisalwaysusedforthetransferofexclusivelyfluidswhichareconductiveorsolubleinwateror

Installationandoperation

Ingeneral,thepumphastobeconnectedloadfree.Neglectingthiscausesleakageandmaybeevendamages.To
avoidvibrations,pulsationdampersandcompensatorsarerecommended.Beforeconnectingthepump,takethe
blindplugsoutofallconnections.TheconnectionsofALMATECCXMpumpshaveslightlytaperedthreads.Use
threadsealonlysparingly,otherwisetheconnectionscouldbedamaged.

Ondelivery,theliquidconnectionsofallCXMpumpsaresituatedasfollows:
Suctionport“facesidehorizontal”,dischargeport“uppersidevertical”(seeillustration)
Byturningthecenterblockby180°byitslongitudinalaxis–afterunscrewingandtakingoutthe

Theproductconnectionsarebothonthefacesideasfollows:
Suctionport“facesideatthebottom”,dischargeport“facesideonthetop”(seeillustration)

Theoperatorisresponsibleforanadequatelystabilityandanappropriatefixationofthepipingaccordingtothestate
oftheart.Tofacilitatetheinstallationandmaintenanceshutoffvalvesshouldbeinstalledrightbeforeandafterthe
pump.Thenominalwidthoftheconnectionpipeshastobechoseninaccordancetotheconnectionsofthepump.A
smallerpipingcancausecavitation(suctionline)aswellasalossofperformance(suctionanddischargeline).Incase
thepipeistoobig,thedrysuctioncapacityofthepumpcandecrease.Sealthesuctionlinediligently;hosepipes
shouldbesuitablyarmoured.Asuctionlinecontinuouslyrisingwillpreventtheformationofairlocksinthelinewhich
wouldaffectthesuctionlift.

Theairinletislocatedatthefrontofthepumpinthemiddleofthecenterhousing[2].Beforeinstallationmakesure
thattheairsupplypipeisfreeofsolids.Tosupplythepumpwithdrivingairsufficiently,thepipediametershould
matchthesizeoftheairinlet.Takecarethatnodirtorparticlescanintrudeintothepumpduringtheconnection,as
thesecanaccumulateinsidethepumpandcancausemalfunctions.TheintegratedaircontrolsystemPERSWINGP®is
aprecision‐controlthatrequiresoil‐free,dryandcleancompressedairforoptimalfunction.Ifhumidityisexpected,a
waterseparatororairdryerhastobefittedtoprotectthepumpfromblockingbyice.Theidealconditionisthe
dewpointofairat‐20°C.Inhumidsurroundings,icingfromtheoutsidemayoccurdespitethedrivingairisdried.Ifso,
aprolongedwaste‐air‐exhaust(ca.500mmbypipeorhose)canbehelpful.Wheninstallingthepumpintoboardsor

11
cabinets,ithastobeensuredthatcoldairdoesnotgetcaughtbehindthemuffler.Inapplicationswithatendencyto
freezingatthewasteairexhaust,goodexperiencesinpractisehavebeenachievedbypre‐heatingthedrivingairto
increasethedistancetothedewpointoftheair.Doingso,ithastobeconsideredthatthedrivingairtemperature
generallymaynotexceed50°Ctoavoidexpansionandstickingeffectsontheairside.Thismax.airtemperatureisa
wellvalidwhenusingacompressorproducingwarmairwhichise.g.oftentruefortruckcompressors.

Thepressureofthedrivingairshouldbelimitedtotheamountrequiredtomeettheperformanceneeded.Excessive
pressureincreasesboththeairconsumptionandthewearofthepump.Thepumpisregulatedbytuningtheflow
rateoftheair.Foraproperoperationatthelowerperformancerangetheregulationviaaneedlevalveis
recommended.Anemptypumphastobedrivenslowly(e.g.viaaneedle‐valve).Thepumpstartsautomatically.
PumpsoftheCXMseriesareself‐primingwhendry,thusitisnotnecessarytofillthesuctionlineofthepump.The
suctionliftcapacityofaliquid‐filledpump,however,ismuchhigher.Thepumpisappropriateforrunningdryduring
slowoperation.Dryrunningathighstrokefrequencycausesprematurewear.Thepumpscanbriefly(uptomax.one
hour)beoperatedagainstacloseddischargeline.Throttlingonthesuctionsidemaydamagethepump.Whenthe
pumpoperationhasbeenstoppedbyacloseddischarge,thepressureequilibriumofthediaphragmsmustbe
ensured.Thiscanbeachievedbykeepingthepumpconnectedtotheairsupplypressure;forlongerstoppage,the
pumpmustbereleasedfromthepressurewithinthesystemonbothfluidsideandairsupplyside.

Installation,operation,andmaintenancebyqualifiedstaffonly.
Beforeputtingthepumpintooperationaswellasaftersomehoursofpumping,thehousingbolts
[9]havetobefixedaccordingtothetorquedata.Fixingtheboltsisnecessaryaswellafterlonger
periodsofstoppage,atextremetemperaturevariations,aftertransportanddismantlingthepump.
Incaseoftemperaturevaryingbetweenextremesorhightemperaturedifferencebetweenthe
liquidandthesurrounding,thehousingboltsshouldbecontrolledmorefrequently(interval
proposalsareavailableonrequest).
Beforestart‐upofthepumpanyoneshouldacquaintoneselfwiththeexplanationsofthechapter
troubleshooting(seepages14/15).Onlybythisthedefectquicklycanberealizedandeliminatedin
caseoftrouble.Problemswhichcannotbesolvedorwithanunknownreasonshouldbepassedon
tothemanufacturer.
Beforeanymaintenanceandserviceproceduresarisingonthepumporontheoptional
equipments,thecompleteinstallationhastobeturnedoffandprotectedagainstaccidentalturnon.
Thisispossiblebyalockableemergencystopfortheairsupplyofthepump.Additionaladanger
signagainstrestartshouldbeattached.
Pressuretestsoftheplantapumpisincludedinmayonlybecarriedoutwiththepump
disconnectedfromthepressureonbothportsorbyusingthepressurethepumpdevelopswhile
operating.Theloadofapressureintheplantmaydamagethepump.
Pumpmustnotbeoperatedwithapositivesuctionpressure.
Dependingontheconditionsofoperation,theliquidconveyedmightescapefromthepump
throughthemufflerincaseofadiaphragmrupture(inthiscasemufflerhastobereplaced).For
furthersafetyrequirementstheoptionalequipmentdiaphragmmonitoringandbarrierchamber
systemarerecommended.
Incaseofadiaphragmrupture,itmightbepossibleforthefluidpumpedtointrudeintotheairside
ofthepump.Inveryadverseconditions‐e.g.pressurewithinthefluidsystemduringstoppedair
supply‐thefluidmightaswellfinditswayintotheairsupplylines.Toprotectotherdeviceslike
pulsationdampersorevenpneumaticvalves,itisrecommendedtoprotecttheairsupplyline
accordingly,e.g.viaanon‐returnvalve.Thiswouldaswellavoidpollutingtheairsupplyline.
Thestateofthemufflerhastobeinspectedregularly,asablockedmufflercanbeforcedoutofthe
pump.Ifthishappens,damagesofpropertiesand/orpersonscannotbeexcluded.

Iftheproducttendstosettle,thepumphastobeflushedregularly.Forlargersolidsafilterhasto
beinstalledinthesuctionline.
Incaseofdeliveryofhotliquidsthewettedpumpmustnotstandstillforalongertime,becauseit
couldleadtotemporaryleaksinthevalveareaandtoablockadeoftheaircontrolsystem.
Therelevanteffectivesecurityadviseshavetoberespected.
Poolsofliquidwhichappearinthenearouterareaofthepumphavetobeinspectedondanger
potential,ifnecessarysafetymeasuresaretobetaken.
Chemicalandbiologicalreactionsintheproductchamberofthepump(mixtureofdifferent
substances)andthefreezingoftheliquidhavetobeavoided.
Beforestartingtodisassemblethepump,takecarethatthepumphasbeenemptiedandrinsed.
Bothportspipingaretobeclosedanddrainedifapplicable.Furtherthepumphastobecutofffrom
anyenergyontheairandproductside.Ifthepumpisbeingdeportedfromtheplant,areference
aboutthedeliveredliquidhastobeattached.
Pleaserespecttherelevantadditionalsecurityadvices,ifthepumphasbeenusedforaggressive,
dangerousortoxicliquids(e.g.suitableprotectiveequipmentaccordingtothesafetydatasheetof
theliquid).Incaseofadiaphragmrupture,itispossiblethatresiduesoftheliquidremainbehind
thediaphragms,intheareaoftheaircontrolsystemandatthemuffler,despiteofseveralflushing
processes.Hence,appropriatesafetyequipmentaccordingtothesafetydatasheetoftheliquidis
indispensable.
Beforeputtingthepumpbackintooperation,thetightnessofthepumphastobechecked.
Air‐operateddiaphragmpumpscanleadtobruiseswhenlifting,sinkingorassemblingthem.
Appropriateaccessoriesandsafetyequipmentaretobeused.Bigandheavymoduleshavetofixed



Usingassubmersiblepump

ConsiderthefollowingadviseswhenusingaCXMpumpasasubmersiblepump:Whenimmersinganair‐ operated
diaphragmpump,itmustgenerallybeensuredthatthewasteairisdeductedabovethefluidlevelwithapipeor
similar.Thepumpmustbelocatedverticallyuprighttoguaranteeproperfunction.Minuteleakageontheairinletor
outletcanblocktheairvalve.Thepumpmustbedisconnectedfromthepressurewithinthesystemduringstandstill.
Whenchoosingthepumptype,itmustbetakenintoconsiderationthatallexternalparts‐eventhosenon‐wetted
duringstandardoperation‐likecovers,shockabsorbers,connectionsetc.mustberesistanttothefluidpumped.
Pleaseconsideraswellthatdependingonthematerial,thepumpmustbeweightdownresp.fixed.


Additionaltemperaturehints

Thetemperatureandpressurelimitationslistedonpage5aresolelybasedonmechanicaltemperaturelimitsofthe
housingmaterialused.Dependingonthefluidpumped,themaximumsafeoperatingtemperatureofthehousing
materialcanbereducedsignificantly.


13
Ageneralaspectoflowertemperaturesis,thatbelow0°C(32°F)cold‐brittlingoftheelastomersusedwithinthe
pumpscanresultsinacceleratedwear.Regardingthehousingmaterials,pleasenotethatPE‐otherthanPP‐keeps
itsmechanicalstrengthsatlowtemperaturesandPTFEkeepsmechanicallystableaswellforanextended
temperaturerange.ALMATECpumpsoftheCXMseriescanthereforebeoperatedsafelyaswellwithinlow‐
temperatureinstallations:However,withliquidsbelow0°C(32°F)acceleratedwearofinternalpartshastobe
accepted.Moreover,freezing,boggingorcrystallisationofthefluidpumpedmustbeavoided,especiallywithinthe
pump.
Pleaseconsider,thatviscosityandspecificgravityofmostfluidschangewithtemperature(mostoftenincreasingat
lowertemperature).Dependingontheapplication,thisfactmaynotonlyresultinresultinareducedflowrate,the
pumpmayevenbeunabletoprimethethickerand/or“heavier“fluidanymore.
Incaseofvaryingapplicationtemperatures,thehousingbolttensionhastobecontrolledverythoroughly,as
variationslikethesecanchangetheeffectivetensionofthehousingboltsviathedifferentthermalexpansion
characteristicsofsingle.


Disassemblyandassemblyadvises

ThegeneraldesignoftheALMATECCXMpumpsissimple.Aplastictooldesignedforthemountingoftheaircontrol
