6.3 Installation of T0, T0A pump series
Pumpcouplingmustbeperformedonlywhentractorisoff.Makesurethatthetractorcannotbeaccidentallystartedacci-
dentally. All T0 and T0A pumps can be either mounted on permanent stations or on mobile trolley.
Thecardanshaftshouldbeconnectedwithanalignmentanglelessthan10°(g.7).Suctionanddeliverypipesmustbe
correctly mounted and not subject to stress during pump operation. Also refer to paragraph 6.2.
 InT0FandT0FAexecution(g.8)thesepumpsarettedfordirectcouplingtothep.t.o.oftractors.Forinstallationproceedasfol-
lows:
- Liftthepumpuntilthep.t.o.isalignedwiththepumpcoupling;slightlyrotatethecouplingtomeetthesplinesandpushthepumptowardsthe
p.t.o.
- Pullthecouplingexternalringtowardsthepump,overcomingthereturnspringresistance;nowpushthepumptowardsthep.t.o.tondthe
foreseencouplingposition.
- Releasetheringbacktoitsoriginalposition.Checkthatinstallationismadecorrectlybypushingthepumpforwardandbackward:thepump
mustremainrmlyanchoredtothep.t.o.
- Thepumpwillresultradiallyswingingonthep.t.o.Completeanchorageismadebyhookingthetwochainsattheendsofthetraverseanchor
barxedonpumpsupport.Chainspreventthepumptorotatefurthertothep.t.o.motion.
- Tograntarmanchorageitisimportanttondsuitablepoints/positionsonthetractorwherechainscanbehooked.Ontheotherhand,chains
shall be long enough to reach any anchorage point under or above the p.t.o.
- Ifanchoragepointsareunderthep.t.o.,thechainwiththespringwillbeattheleftofthepump.Ofcourse,ifanchoragepointsareabovethe
p.t.o.,thechainwiththespringwillbeattherightofthepump.
- Usetheaccessoriessuppliedwiththepump(elbow,connectionandfootvalve)toconnectthepipes.

- Whenstartingforthersttime,thepumpbodymustbelledwithwater:usetheportintheupperpartofthepumpbodyortheoutlet.This
operationisnotrequiredpriortofollowingstartings,becausethebuilt-in-checkvalvepreventstheemptyingofthedeliverypipeandguarantees
enoughwaterforacorrectpriming.Timeofprimingmaydependonrotationspeedaswellasonlengthanddiameterofinletpipeandcanvary
fromfewsecondstoafewminutes.
Thepumpoperationmuststaywithinthelimitsandmusttakeplacewithoutabnormalvibrationandnoise.Maintainthedata
providedontheoperatingplate.Theuseofthepumpwithdifferentdatamaycauseirreparabledamage.Afterstartingcheck
again the alignment of the pumping units.
8. Maintenance
8.1 Bearings lubrication
Provideoilreplacementaftertherst80hoursofoperation.Itisnecessarytorepeatthisoperationevery400/1000operation
hours.Provideoilreplacementalsoincaseofsuddenoillowering.Foroilreplacementreferto tab. 1.
 DON’TWASTETHEENVIRONMENTWITHOUTOFUSEOIL.
Whenthepumpremainsinactiveforalongperiod(especiallyduringcoldseason),drainoutthewaterfromthedrainage
pluginordertopreventfreezingdemages.Itisadvisabletoprotecttherotatinginternalpartswithantirustoil(without
