andpouringoperations.Maximumworkingpressure:180bar.
‐ Thepumpcanworkwithcleanwater,watersolutions,lightoilsandnon‐aggressiveliquidswithaneutralPH.
‐ Readtheinstructionmanualcarefullyandpractiseusingtheequipmentbeforeapplication.
‐ Alwaysuseprotectivegoggles,shoesandgloves.
‐ Allpumpsaretestedindividually,aretoughandveryrobustandthereforeverysafe.
‐ Bodyofthepumpmadeofbrass.
‐ Donotmodifythepump(weldedparts,etc.).
‐ Usethehandlesonthepumpfortransportingthedevice.Donotusethehoseorpipe.
‐ Never exceed maximum working pressure of the pump. Ensure that all the equipment and accessories are
suitableforthemaximumworkingpressure.
‐ Neverturnonthepumpwhenthepumpisnotconnectedtotheplant.Donotpressurizethepumpwithoutbeing
connectedtoanitemtobepressurizedunlessablankingplugisfittedtotheoutletport.
‐ Nevertightenorloosenconnectionswhiletheyareunderpressure.
‐ Checkthattherearenodamagesonthepump.Iftherearewornordamagedpieces,replacethemimmediately.
‐ Respectelectricalsafetyrequirements:anyoperationmustbeperformedbyqualifiedpersonnel,onlywhenthe
machineisdisconnectedfrompower.Replaceanyelectricalcomponentsifdamaged.Keepdryanyelectricpart.
‐ Beforestartingoperation,checkthattheinstallationiscorrect,theoperatorpositionissafeandtheworkingzone
isoutofboundstoallpersonnel.
‐ Inallcases,theoperatorshouldhavereceivedadequatetrainingregardingthehandlingofthedeviceandlogical
safetycriteriaassociatedwiththemovementofheavyloads.

ASSEMBLYANDOPERATINGINSTRUCTIONS
Thecomponentsareshippedunassembledtopreventbreakageorunnecessarybulkduringtransportorthestockage
inwarehouse.Beforestartingoperations,checkifthepumphasbeenlabelledwithserialnumberandtechnicaldata.
Keeppackageforfurthertransportsorstockage.


Assemblethedeviceinaccordancewiththenextprocedure,firstcheckingthatyouhaveallthenecessarymaterial.
UsePTFEtapeonallthreadstopreventanyleakage.
Beforestartinganyoperation,cleanthetanktoeliminateanyresidueorwaste.
To avoid pressure oscillation due to air in the system, it is necessary to purge the air circuit to fill the system
completely.
1. Assemblyallcomponents.Thepumpisprovidedwithglycerinpressuregaugeø60,coilanddoublecontrolvalve.
2. Placethepumpbodyoverthetankandfixitwiththesuppliedscrews.
3. Screwsuctionpipeintothebaseofthepump.
4. Screwthedoublecontrolvalveunitintothepumpblock.Screwthegaugetubeverticallyandmountthegauge.In
ordertofavourtheimmediatereadingduringthetest,pointthepressuregaugeinthedirectionoftheoperator.
Remembertoapplynecessarysealstoallcomponents.
5. Placetheequipmentonaflatandsolidarea.
6. Fillupthe tank and ensure the suction tube iscompletely submerged. Use anticorrosive,antioxidant fluidora
mixtureofwaterandemulsifiableoilinordertopreventoxideformationinsidethemachine.Checkthesuction
filterbeforeanytesting.
7. Connect one end of the hose to the pump and the other end to the system or equipment to test (pipe, tank,
valve,etc.).
8. Beforeoperatingthepumpalwaysmakesurepipeconnectionsarecleanandfullytightenedup;allaccessories
mustbefittedcorrectly:suctiontubewithnutandfilter,pressuregaugeandhoseforhighpressure.Alwaysuse
protectivegoggles,shoesandgloves.
9. Verifythatelectricalrequirements of the motor are according to the electric power supply in the plant. Then,
connectthemotortothepowerline.Checkthatthemotorrunscorrectly.Ensuregoodmotorventilation.Check
thatmotorcanhaveenoughfreshairflowfromthechassis.
10. Pre‐fillthesystemorequipmentbeforestartingthetestwiththesameliquidthatwillbeusedfortesting.
11. Tostartthetest,closethedischargevalveB(right)andopen the flow‐valve A (left) manually. There are two
handwheelsonthecontrolvalveblockforthesetwovalves.
12. SwitchonthepumpandregulatetheoutletvalueofthepressureusingtheredknobC,
thisoperatesonaby‐passdesignedtodeliverthenecessarypressurestepbystep.
13.
Checkthepressureshowninthegaugeanddonotexceedthemax.pressure.
14.
Oncereachedtherequiredpressure,closetheflow‐valveA,tomaintainthesame
pressurevalueintheelementunderpressure.Makesuretherearenoleaks.
15. Tofinishtheoperation,openthedischargevalveBandsurplusliquidwillrunbackinto
thetankthroughadischargepipe.
16.
Toperformanothertest,followtheinstructionsfromthebeginning.
Replacethesealsatleasteverytwoyears.
Nopreventivemaintenanceisrequired.Ifthepumpisnotusedforalongtime,preservepackagefromhumidityor
rain.Thepumpshouldbekeptawayfromextremetemperature.
Ensurethatalltheequipmentandaccessories
aresuitableforthemaximumworkingpressure.

TROUBLESHOOTING

‐ Pumpdoesnotreachthedesiredpressure:check inorder:suctionfilter,airinthepump,pressurevalves,inlet
connections,seals.
‐ Pressure change continuously: check the presence of air bubbles in the circuit, check the presence of dirt, the
filter,valvesandseals.
‐ Pressuredrop:Checkdirtyonfilterandvalves.Checkthegaskets.
‐ Noisy pump: Check air suctions. Clean and move the valve. Clean the filter. Check water temperature. Check
mechanicalparts,particularlyballbearings.
‐ Water with oil: Change the oil and look for damaged gaskets and rings. High humidity may cause this
inconvenience.
‐ Waterleakingfromthehead:Changedamagedgasketsandrings.
‐ Oilleaks:replaceoilgaskets.
‐ Motor Hum: Turn offthe motor immediatelyand verifyifthepumpisnotblocked.Checkifthevoltageinthe
electricnetcorrespondswiththedatalabel.Rememberthatlongpowercordsmaycausevoltagelosses.Verify
voltageatthepumpplug.
‐ Motor stops suddenly: Thermicprotection switched off thepump for too high temperature. Check if voltage is
correct.Wait10minutestore‐start.
‐ Motor does not start: Check electrical connections, thermic protection, emergency stop switch and magneto
switchonthemachine.Checkdifferentialonthepowerline
