3 Lifting, transport and storage
3.1 Lifting
ATTENTION! Observe the total weight of the Sulzer units and their attached components! (see
nameplate for weight of base unit).
The duplicate nameplate provided must always be located and visible close to where the pump is installed (e.g.
attheterminalboxes/controlpanelwherethepumpcablesareconnected).
NOTE! Lifting equipment must be used if the total unit weight and attached accessories
exceeds local manual lifting safety regulations.
The total weight of the unit and accessories must be observed when specifying the safe working load of any
liftingequipment!Theliftingequipment,e.g.craneandchains,musthaveadequateliftingcapacity.Thehoist
mustbeadequatelydimensionedforthetotalweightoftheSulzerunits(includingliftingchainsorsteelropes,
and all accessories which may be attached). The end user assumes sole responsibility that lifting equipment is
certied,ingoodcondition,andinspectedregularlybyacompetentpersonatintervalsinaccordancewithlocal
regulations. Worn or damaged lifting equipment must not be used and must be properly disposed of. Lifting
equipment must also comply with the local safety rules and regulations.
NOTE! The guidelines for the safe use of chains, ropes and shackles supplied by Sulzer are
outlined in the Lifting Equipment manual provided with the items and must be fully
adhered to.
The unit must never be raised by the power cable.
Dependingonmodelandmodeofinstallation,theunitsarepreparedatthefactoryforverticalorhorizontal
transportation.
Theunitsareequippedwithasafetyshackle(seriesforverticalsetup)orswivelringbolt(horizontalsetup),
whichallowxingchainsfortransportingorforinstallingorremoving.Werecommendusingchainsfromthe
Sulzer list of accessories.
Take note of the entire weight of the unit (see nameplate Figure 1) The hoist and chain must be
adequately dimensioned for the weight of the unit and must comply with the current valid safety
regulations.
ATTENTION In the case of pumps set up vertically, sealing plugs are mounted for protecting the
thread holes instead of swivel ring bolts. These seals may only be replaced by a
swivel ring bolt for maintenance work but must be screwed on again before startup!
0838-0005 0838-0004
Figure 4: Transport in a horizontal manner XFP Figure 5: Transport in a horizontal manner AFLX/VUPX
ATTENTION α max. ≤ 45°. The angle α between the centre line of the unit and the lifting tools
should not exceed 45°.

10
EN 6556-H
3.2 Transport securing devices
The motor connection cables are protected against the ingress of moisture along the cable by having the ends
sealed with protective covers at manufacture.
These protective covers should only be removed immediately prior to connecting the pumps electrically.
ATTENTION These protective covers only provide protection against water spray or similar and
are not a water tight seal. The ends of the cables should not be immersed in water,
otherwise moisture could enter the connection chamber of the motor.
NOTE If there is a possibility of water ingress then the cables should be secured so that the
ends are above the maximum possible ood level. Take care not to damage the cable
or its insulation when doing this!
In order to avoid damage to the pump shaft or the bearings during horizontal transport the shaft is clamped in
an axial direction when leaving the works.
ATTENTION The motor shaft transport lock must be removed before startup!
3.3 Storage of the units
ATTENTION The Sulzer products must be protected from weather inuences such as UV from
direct sunlight, high humidity, aggressive dust emissions, mechanical damage,
frost etc. The Sulzer original packaging with the relevant transport securing devices
(where used) ensures optimum protection of the unit. If the units are exposed to
temperatures under 0 °C / 32 °F check that there is no water in the hydraulics, cooling
system, or other spaces. In the case of heavy frosts, the units and cable should not
be moved if possible. When storing under extreme conditions, e.g. in tropical or
desert conditions suitable additional protective steps should be taken. We would be
glad to advise you further
NOTE The Sulzer units normally require no maintenance during storage. During longer
storage times, (after approx. one year) the transport locks on the motor shaft (not all
versions) must be dismantled. Coolant is applied to the sealing surfaces by manually
turning the shaft several times (also for the purpose of cooling or lubricating so that
trouble-free function of the sliding ring seal is ensured). No maintenance is required
when storing the motor shaft.

4.2 Leakage sensor (DI)
The leakage sensor carries out the seal monitoring function and signals the ingress of moisture into the motor
by means of a special electronic device; see also section 5.6
ATTENTION If the leakage sensor (DI) is activated the unit must be immediately taken out of
service. Please contact your Sulzer Service Centre.
4.3 Temperature monitoring of the stator
Thermallimitersprotectthestatorfromoverheatinginthecaseofasymmetricphaseloadingorvoltage,

standardversion.Thisenablesprematureswitchingo󰀨ofthesubmersiblemotor(e.g.,duetowear-related
increase in bearing temperature).
Switching temperature: Upperbearing=140°C/284°F      
   Lowerbearing=130°C/269°F
4.5 Temperature sensor indication
A continuous indication of the temperature in the stator and the bearings is not possible using bimetallic thermal
limitersorthermistors.ForthisapplicationitisnecessarytotthermalsensorsofthetypePT100withlinear
characteristicsintothestatorandbearingblocks.Thistypeofresistorhasalinearcharacteristic,i.e.the
resistance rise is proportional to the temperature rise.
NOTE Running the pump with the thermal and/or leakage sensors disconnected will
invalidate related warranty claims.

ATTENTION Thermistors or PT 100 devices must never be directly connected into the control or
power system. They must always be connected to a suitable evaluation device.
The thermal monitoring circuit must be wired into the motor contactors in such a manner that a manual reset is
required.
4.6 Operation with frequency inverters
The stator design and the insulation grade of the motors from Sulzer means that they are suitable for usage
with frequency inverters. It is however essential that the following conditions are met:
• The guidelines for EMC (electromagnetic compatibility) are complied with.
• Speed/torquecurvesformotorsdrivenbyfrequencyinverterscanbefoundinourproductselectionrange.
• Explosion-proofmotorsmustbeequippedwiththermistors(PTCtemperaturesensors)ifoperatedinhazard-
ous areas (ATEX Zone 1 and 2).
• MachinesdesignatedasExmachinesmaynever,withoutexception,beoperatedusingamainsfrequency
that is greater than the maximum of 50 or 60 Hz as indicated on the type plate. Make sure that the rated
currentspeciedonthetypeplateisnotexceededafterstartingthemotors.Themaximumnumberofstarts
according to the motor datasheet may not be exceeded.
• Machines that are not designated as Ex machines may only be operated using the mains frequency indicated
on the type plate. Greater frequencies can be used but only after consulting with and receiving permission
from the Sulzer manufacturing plant.
• Foroperationofex-motorsonfrequencyinvertersspecialrequirementsinrelationtothetrippingtimesofthe
thermocontrolelements,mustbeobserved.
• Thelowestfrequencymustbesetsothattheminimumuidvelocityof1m/sispresentinthevolute.
• The maximum frequency must be set so the rated power of the motor is not exceeded.
Modern frequency inverters are using higher wave frequencies and a steeper rise on the edge of the voltage
wave. This means that motors losses and motor noise is reduced. Unfortunately these inverter output signals

EN 6556-H
causehighervoltagespikesinthestator.Experiencehasshownthat,dependingonratedvoltageandthe
lengthofthecablebetweentheinverterandthemotor,thesevoltagespikescanadverselya󰀨ectthelifeofthe
motor.Inordertoavoidthis,invertersofthistypemustbeequippedwithsinuslterswhenusedinthecritical
zone (see g 9).Thesinuslterchosenmustbesuitablefortheinverterwithregardtoratedvoltage,inverter
