2 SafetyThese operating instructions contain fundamental informationwhich must be complied with during installation, operation,monitoring and maintenance. Therefore this operating manualmust be read and understood both by the installing personneland the responsible trained personnel / operators prior toinstallation and commissioning, and it must always be keptclose to the location of operation of the machine / unit for easyaccess.Not only must the general safety instructions laid down in thischapter on ”Safety” be complied with, but also the safetyinstructions outlined under specific headings, particularly if thepump/unit is operated in hazardous areas (see section 2.9).
2.1 Marking of Instructions in the ManualThe safety instructions contained in this manual whosenon-observance might cause hazards to persons are speciallymarked with the symbol
general hazard sign to ISO 7000 - 0434The electrical danger warning sign is
safety sign to IEC 417 - 5036,and special instructions concerning explosion protection aremarked
The word
is used to introduce safety instructions whose non-observancemay lead to damage to the machine and its functions.Instructions attached directly to the machine, e.g.- arrow indicating the direction of rotation- markings for fluid connectionsmust always be complied with and be kept in a perfectly legiblecondition at all times.
2.2 Personnel Qualification and TrainingAll personnel involved in the operation, maintenance,inspection and installation of the unit must be fully qualified tocarry out the work involved.Personnel responsibilities, competence and supervision mustbe clearly defined by the operator. If the personnel in question isnot already in possession of the requisite know-how,appropriate training and instruction must be provided. Ifrequired, the operator may commission the manufacturer /supplier to take care of such training. In addition, the operator isresponsible for ensuring that the contents of the operatinginstructions are fully understood by the responsible personnel.
2.3 Non-compliance with Safety Instructions
Non-compliance with safety instructions can jeopardize thesafety of personnel, the environment and the machine / unititself. Non-compliance with these safety instructions will alsolead to forfeiture of any and all rights to claims for damages.
In particular, non-compliance can, for example, result in:
- failure of important unit functions,
- failure of prescribed maintenance and servicing practices,
- hazard to persons by electrical, mechanical and chemicaleffects as well as explosion,
- hazard to the environment due to leakage of hazardoussubstances
2.4 Safety Awareness
It is imperative to comply with the safety instructions containedin this manual, the relevant national and international explosionprotection regulations, health and safety regulations and theoperator’s own internal work, operation and safety regulations.
Ex symbol relates to additional requirements which mustbe adhered to when the pump is operated in hazardous
areas.
2.5 Safety Instructions for the Operator / User- Any hot or cold components that could pose ahazardmustbeequipped with a guard by the operator.
- Guards which are fitted to prevent accidental contact withmoving parts (e.g. coupling) must not be removed whilst theunit is operating.
- Leakages (e.g. at the shaft seal) of hazardousmedia handled(e.g. explosive, toxic, hot) must be contained so as to avoidany danger to persons or the environment. Pertinent legalprovisions must be adhered to.
- Electrical hazards must be eliminated. (In this respect refer tothe relevant safety regulations applicable to differentcountries and/or the local energy supply companies.)
If the pumps/units are located in hazardous areas, it isimperative to make sure that unauthorized modes of
operation are prevented. Non-compliance may result in thespecified temperature limits being exceeded.

2.6 Safety Instructions for Maintenance, Inspectionand Installation Work
The operator is responsible for ensuring that all maintenance,inspection and installation work be performed by authorized,qualified specialist personnel who are thoroughly familiar withthe manual.The pump must have cooled down to ambient temperature,pump pressure must have been released and the pump musthave been drained.Work on the machine / unit must be carried out only duringstandstill. The shutdown procedure described in themanual fortaking the unit out of service must be adhered to without fail.Pumps or pump units handling media injurious to health mustbe decontaminated.Immediately following completion of the work, allsafety-relevant and protective devices must be re-installed and/ or re-activated.Please observe all instructions set out in the chapter on”Commissioning/Start-up” before returning the unit to service.
2.7 Unauthorized Modification and Manufacture ofSpare Parts
Modifications or alterations of the equipment supplied are onlypermitted after consultation with the manufacturer and to theextent permitted by the manufacturer . Original spare parts andaccessories authorized by themanufacturer ensure safety. Theuse of other parts can invalidate any liability of themanufacturerfor consequential damage.
2.8 Unauthorized Modes of OperationThewarranty relating to the operating reliability andsafety of theunit supplied is only valid if the equipment is used inaccordancewith its designated use as described in the following sections.The limits stated in the data sheetmust not be exceeded underany circumstances.
2.9 Explosion ProtectionIf the pumps/units are installed in hazardous areas, themeasures and instructions given in the following
sections 2.9.1 to 2.9.6must be adhered to without fail, to ensureexplosion protection.
2.9.1 Unit FillIt is assumed that the system of suction and dischargelines and thus the wetted pump internals are completely
filled with the product to be handled at all times during pumpoperation, so that an explosive atmosphere is prevented.
If the operator cannot warrant this condition, appropriatemonitoring devices must be used.
In addition, it is imperative to make sure that theseal chambers, auxiliary systems of the shaft
seal and the heating and cooling systems are properly filled.
2.9.2 MarkingThe marking on the pump only refers to the pump part,i.e. the coupling andmotor must be regarded separately.
The couplingmust have anECmanufacturer’s declaration. Thedriver must be regarded separately.Example of marking on the pump part: Ex II 2 G T1 - T5The marking indicates the theoretically available temperaturerange as stipulated by the respective temperature classes. Thetemperatures permitted for the individual pump variants areoutlined in section 2.9.5.
2.9.3 Checking the Direction of Rotation (see also 6.1.4)If the explosion hazard also exists during the installationphase, the direction of rotation must never be checked
by starting up the unfilled pump unit, even for a short period, toprevent temperature increases resulting from contact betweenrotating and stationary components.
2.9.4 Pump Operating ModeMake sure that the pump is always started up with thesuction-side shut-off valve fully open and the discharge-sideshut-off valve slightly open. However, the pump can also bestarted up against a closed swing check valve. Thedischarge-side shut-off valve shall be adjusted to comply withthe duty point immediately following the run-up process (see6.1.7 ).Pump operation with the shut-off valves in the suctionand/or discharge pipes closed is not permitted.
In this condition, there is a risk of the pump casingtaking on high surface temperatures after a very
short time, due to a rapid temperature rise in the pumpedproduct inside the pump.Additionally, the resulting rapid pressure build-up inside thepump may cause excessive stresses on the pump materials oreven bursting.Theminimum flows indicated in section 6.2.5 refer to water andwater-like liquids. Longer operating periods with these liquidsand at the flow rates indicated will not cause an additionalincrease in the temperatures on the pump surface. However, ifthe physical properties of the media handled are different fromwater, it is essential to check if an additional heat build-up mayoccur and if theminimum flow rate must therefore be increased.To check, proceed as described in section 6.2.5.In addition, the instructions given in section 6 of this operatingmanual must be observed.
Both gland packings and mechanical seals mayexceed the specified temperature limits if run dry.
Dry runningmay not only result from an inadequately filledseal chamber, but also from excessive gas content in themedium handled.Pump operation outside its specified operating range mayalso result in dry running.In hazardous areas, gland packings shall only be used ifcombined with a suitable temperature monitoring device.
2.9.5 Temperature LimitsIn normal pump operation, the highest temperatures areto be expected on the surface of the pump casing, at the
shaft seal and in the bearing areas. The surface temperature atthe pump casing corresponds to the temperature of themediumhandled.If the pump is heated, it must be ensured that the temperatureclasses stipulated for the plant are observed.In the bearing bracket area, the unit surfaces must be freelyexposed to the atmosphere.In any case, responsibility for compliance with thespecified product temperature (operating temperature) lieswith the plant operator. Themaximum permissible producttemperature depends on the temperature class to becomplied with.The table below lists the temperature classes to PrEN 13463-1and the resulting theoretical temperature limits of the mediumhandled. In stipulating these temperatures, any temperaturerise in the shaft seal area has already been taken into account.

Based on an ambient temperature of 40�C and propermaintenance and operation, compliance with temperatureclass T4 is warranted in the area of the rolling element bearings.A special design is required for compliance with temperatureclass T6 in the bearing area. In such cases, and if ambienttemperature exceeds 40�C, contact the manufacturer.
2.9.6 Maintenance
Only a pump unit which is properly serviced andmaintained in perfect technical condition will give safe
and reliable operation.This also applies to the reliable function of the rolling elementbearings whose actual lifetime largely depends on theoperating mode and operating conditions.Regular checks of the lubricant and the running noises willprevent the risk of excessive temperatures as a result ofbearings running hot or defective bearing seals (also seesection 7.2.2.2).The correct function of the shaft sealmust be checked regularly.Any auxiliary systems installed must be monitored, ifnecessary, to make sure they function correctly.Gland packings must be tightened correctly, to preventexcessive temperatures due to packings running hot.
3 Transport and Interim Storage3.1 Transport
Transport of the unit requires proper preparation and handling.Always make sure that the pump or the unit remains inhorizontal position during transport and cannot slip out of thetransport suspension arrangement. Do not use lifting slings onthe free shaft end of the pump or on the motor eyebolt.
If the pump / unit slips out of the suspension arrange-ment, it may cause personal injury and damage to prop-
erty.

3.2 Interim Storage (Indoors) / Preservation
When the unit is temporarily put into storage, only the wettedlow alloy components (e.g. JL1040, JS1025, GP240GH+Netc.) must be preserved. Commercially available preservativescan be used for this purpose. Please observe themanufacturer’s instructions for application / removal.The relevant procedure is described in section 6.3.The unit / pump should be stored in a dry room where theatmospheric humidity is as constant as possible.If stored outdoors, the unit and crates must be covered bywaterproof material to avoid any contact with humidity.
Protect all stored goods against humidity, dirt,vermin and unauthorized access! All openings of
the assembled unit components are closed and must only beopened when required during installation.All blank parts and surfaces of the pump are oiled or greased(silicone-free oil and grease) to protect them against corrosion.

gulations. This is indicated on the pump name plate andmotor name plate (see 2.9).
5.2 Checks to be Carried out Prior to InstallationAll structuralwork requiredmusthavebeenprepared inac-cordance with the dimensions stated in the dimension ta-ble / general arrangement drawing.The concrete foundations shall have sufficient strength(min. class X0) to ensure safe and functional installation inaccordance with DIN 1045 or equivalent standards.Make sure that the concrete foundation has set firmly beforeplacing the unit on it. Its surface must be truly horizontal andeven. The foundation bolts must be inserted in the baseplateholes.
5.3 Installing the Pump/UnitThe instructions given below refer to pump installation on agrouted baseplate and rigid foundation.After placing the pump on the foundation, align it with the help
of a spirit level placed on the shaft/discharge nozzle. Permiss-ible deviation 0.2 mm/m. The correct distance between thecoupling halves as specified in the general arrangement draw-ing must be observed. Shims shall be fitted between the base-plate and the foundation itself; they shall always be inserted tothe left and right of the foundation bolts and in close proximityto these bolts. For a bolt-to-bolt clearance > 800 mm, additionalshims shall be inserted halfway between the adjoining holes.Allshims must lie perfectly flush.Insert the foundation bolts and set them into the foundationusing concrete.When the concrete has set, align the baseplateas described in section 5.3.1 and tighten the foundation boltsevenly and firmly. Then grout the baseplate using low-shrink-age concrete with a standard particle size and awater/concreteratio of ≦ 0.5. The flowability must be produced with the helpof a solvent. Secondary treatment of the concrete to DIN 1045is an absolute necessity.
Fig 5.3-1 Fitting required shimsTo ensure low-noise operation, the unit can be mounted onvibration dampers (please confirm with KSB first). Expansionjoints can be fitted between pump and suction/discharge line.The so-called ”foundationless installation” on a baseplate andwith horizontally flexible adjusting elements is permissible. Forpermissible forces andmoments please refer to the general ar-rangement drawing of the pump.
5.3.1 Aligning the Pump/DriveAfter fastening the baseplate on the foundationand connecting the piping, the coupling must be
thoroughly checked and the pump set be realigned (at themotor), if required.Prior to checking the alignment/realignment, loosen supportfoot 183 and re-tighten without transmitting any stresses orstrains.Coupling check and realignmentmust be effected even if pumpand motor are supplied completely assembled and aligned ona common baseplate.The pump set is correctly aligned, if a straight-edge placedaxially on both coupling halves is the same distance from eachshaft at all points around the circumference. In addition, the dis-tance between the two coupling halves must remain the sameall around the circumference. Use a feeler gauge, a wedgegauge or a dial micrometer to verify (see Figures 5.3-2 and5.3-3).

Fig. 5.3-3: Aligning a spacer-type couplingThe radial and axial deviation (tolerance) between the twocoupling halves shall not exceed 0.1 mm.
Improper alignment of the unit can cause damage to boththe coupling and the unit itself!
Motor alignment by means of adjusting screwsIn order to realign the coupling, first loosen the 4 hex. head boltson the motor as well as the lock nuts.Turn adjusting screw by hand or by means of an open-jawedwrench until the coupling alignment is correct. Then re-tightenthe 4 hex. head bolts and the lock nuts.
Fig. 5.3-4: Aligning the motor by means of adjusting screws5.3.2 Place of Installation
The volute casing and discharge cover take on roughlythe same temperature as the medium handled. The dis-
charge cover, bearing bracket and bearing housingmust not beinsulated.Take the necessary precautions to avoid burns.5.4 Connecting the Piping
Never use the pump itself as an anchorage pointfor the piping. The permissible pipeline forces
must not be exceeded (see section 4.3.5).Suction lift lines shall be laid with a rising slope towards thepump and suction head lines with a downward slope towards
the pump. The pipelines shall be anchored in close proximity tothe pump and connected without transmitting any stresses orstrains. The nominal diameters of the pipelines shall be at leastequal to the nominal diameters of the pump nozzles.It is recommended to install check and shut-off elements in thesystem, depending on the type of plant and pump. Itmust been-sured, however, that the pump can still be drained and dismant-led without problems.Thermal expansions of the pipelines must be compensated byappropriate measures so as not to impose any extra loads onthe pump exceeding the permissible pipeline forces and mo-ments.
An excessive, impermissible increase in the pipelineforces may cause leaks on the pump where the medium
handled can escape into the atmosphere.Danger of life when toxic or hot media are handled.The flange covers on the pump suction and discharge nozzlesmust be removed prior to installation in the piping.5.4.1 Auxiliary ConnectionsThe dimensions and locations of the auxiliary connections(cooling, heating, barrier liquid, flushing liquid, etc.) are indi-cated on the general arrangement drawing or piping layout.
These connections are required for properfunctioning of the pump and are therefore of vital
importance!5.4.2 Coupling Guard
In compliance with the accident prevention regulationsthe pumpmust not be operated without a coupling guard.
If the customer specifically requests not to include a couplingguard in our delivery, then the operatormust supply one. In thiscase, it is important to make sure that the materials selected forcoupling and coupling guard are non-sparking in the event ofmechanical contact. KSB’s scope of supply meets this require-ment.
5.5 Final CheckRe-check the alignment as described in section 5.3 and verifythe correct distance between the coupling and the couplingguard.It must be easy to rotate the shaft by hand at the coupling.
5.6 Connection to Power SupplyConnection to the power supply must be effected by atrained electrician only. Check available mains voltage
against the data on themotor rating plateand selectappropriatestart-up method.We strongly recommend to use a motor protection device(motor protection switch).
In hazardous areas, compliance with IEC60079-14 is anadditional requirement for electrical connection.
6 Commissioning, Start-up / ShutdownCompliance with the following requirements is ofparamount importance. Damage resulting from
non-compliance shall not be covered by the scope of warranty.6.1 CommissioningBefore starting up the pump make sure that the following re-quirements have been checked and fulfilled.If a constant-level oiler is provided, screw same into the uppertapping hole of the bearing bracket prior to adding the oil (see6.1.1).The operating data, the oil level, if required (6.1.1), and thedirection of rotation (6.1.4)must have been checked. The pumpset must have been primed (6.1.3).- Make sure that the unit has been properly connected to theelectric power supply and is equipped with all protectiondevices.
- Make sure that all auxiliary connections (5.4.1) are con-nected and functioning.
- If the pumphas been out of service for a longer period of time,proceed in accordance with section 6.4.

6.1.1 LubricantsOil-lubricated bearingsThe bearing bracket has to be filledwith lubricating oil. The qua-lity of oil required is outlined in section 7.2.2.3 and the quantityin section 7.2.2.4.
Fig. 6.1-1: Oil fillProcedure:Unscrew vent plug. Pour in the oil through the vent plug tappinghole after having hinged down the reservoir of the constant-le-vel oiler until oil appears in the vertical portion of the connectionelbow (see Fig. 6.1-1). Then fill the reservoir of the constant-le-vel oiler with oil and snap it back into operating position. Screwvent plug in again. After a short time check whether the oil levelin the reservoir has dropped. It is important to keep the reservoirproperly filled at all times.If access to the vent plug is difficult or impossible, e.g. in caseswhere the motor is arranged above the pump (piggy-back ar-rangement), the oil can be filled in through the connectionelbowof the constant-level oiler.
The oil level should always be below the level ofthe vent opening arranged at the top edge of the
connection elbow. For checking the oil level we recommend toslowly drain oil through the drain plug until the constant-leveloiler starts to operate, i.e. until air bubbles can be seen in theoiler.If no constant-level oiler is provided on the bearing bracket,make sure that the oil level reaches the centreline of the oil levelsight glass arranged at the side of the bearing bracket.
6.1.2 Shaft SealMechanical seals are fitted prior to delivery.
On variants with quench supply tank, the tank must be filled inaccordance with the general arrangement drawing.On variants with double-acting mechanical seal, apply sealingpressure as specified in the general arrangement drawing priorto starting up the pump.External supply requires application of the quantities andpressures specified in the data sheet and general arrangementdrawing.
6.1.3 Priming the Pump and Checks to Be Carried outBefore start-up, the pump, suction line and (if applicable) thethermosiphon tank must be vented and primed. The shut-offelement in the suction line must be fully open.Fully open all auxiliary connections provided (flushing, barrier,cooling liquid etc.) and check the throughflow.For water cooling, use suitable non-aggressive cooling waternot liable to formdeposits and not containing suspended solids.(Hardness: on average 5; pH > 8, or conditioned and neutralwith regard to mechanical corrosion).Inlet temperature tE = 10 to 30 �COutlet temperature tA max. 45 �C
Dry-running will result in failure of themechanical seal and must be avoided!
6.1.3.1Heating (only possible on pump version withdouble-acting mechanical seal)

6.1.4 Checking the Direction of RotationWhen the unit has been connected to the electric power supply,verify the following (local and national regulations have to betaken into account separately):
For trouble-free operation of the pump, thecorrect direction of rotation of the impeller is of
paramount importance. If running in the wrong direction ofrotation, the pump cannot reach its duty point; vibrations andoverheating will be the consequence. The unit or the shaft sealmight be damaged.Correct direction of rotation:The direction of rotationmust correspond to the direction indica-ted by the arrow on the pump. This can be verified by switchingthe pump on and then off again immediately.
Before checking the direction of rotation make sure thatthere is no foreign matter in the pump casing.
Never put your hands or any other objects into the pump.Do not run the pump without liquid whilechecking the direction of rotation. If there is
no medium handled available, the motor’s direction of rotationmust be checked with the pump/motor coupling removed.If the pump runs in the wrong direction of rotation, interchangetwo of the three phases in the control cabinet or motor terminalbox.The safety instructions set forth in section 2.9.3 must be com-plied with.

6.1.5 Cleaning the Plant PipingThe cleaning operation mode and duration for flushingand pickling service must be matched to the casing and
seal materials used.6.1.6 Start-up Strainer
If a start-up strainer has been fitted to protect the pumps againstdirt and/or to retain contamination from the plant, the strainer’scontamination level must be monitored by measuring the diffe-rential pressure so as to ensure adequate inlet pressure for thepump.For installation andmonitoring, see additional instruction sheet.
6.1.7 Start-upBefore starting the pump, ensure that the shut-off valve in thesuction line is fully open! The pump may be started up againsta closed discharge-side swing check valve or slightly openshut-off valve. Only after the pump has reached full rotationalspeed shall the shut-off valve in the discharge line be openedslowly and adjusted to complywith the duty point.Whenstartingup against an open discharge-side shut-off valve, take the re-sulting increase in input power into account!
Pump operation with the shut-off valves inthe discharge and suction pipes closed is
not permitted.The permissible pressure and temperature limits might be ex-ceeded. In extreme cases, the pump may burst.
After the operating temperature has beenreached and/or in the event of leakage, switch off
the unit and re-tighten the bolts between lantern and casing.Check the coupling alignment at operating tem-perature as described in section 5.3.1 and re-
align, if necessary.
6.1.8 ShutdownClose the shut-off element in the discharge line.If the discharge line is equipped with a check valve, the shut-offelement may remain open. If shut-off is not possible, the pumpwill run in reverse rotation. The reverse runaway speedmust belower than the rated speed.Switch off the drive, making sure that the unit runs smoothlydown to a standstill.Close the auxiliary connections but only turn off the coolingliquid supply (if applicable) after the pump has cooled down.The shaft seal in pumps where the liquid is fed in under vacuummust also be supplied with barrier liquid during standstill.In the event of frost and/or prolonged shutdowns, the pump -and if applicable the cooling chambers - must be drained orotherwise protected against freezing.
6.2 Operating LimitsThe pump’s/unit’s application limits regarding pressure,temperature and speed are stated on the data sheet and
must be strictly adhered to.If a data sheet is not available, contact KSB.
6.2.1 Temperature of the Medium Handled, AmbientTemperature, Bearing Temperature
Do not operate the pump at temperaturesexceeding those specified on the data sheet or
the name plate unless the written consent of the manufacturerhas been obtained. Damage resulting from disregarding thiswarning will not be covered by the KSB warranty.Bearing temperatures as described in section 7.2.1 must beobserved.
The safety instructions set forth in section 2.9 must becomplied with.
6.2.2 Switching FrequencyThe start-up frequency usually depends on the max. tempera-ture increase of the motor. It largely depends on the power re-serves of themotor in steady-state operation and on thestarting
conditions (d.o.l., star-delta, moments of inertia, etc.)For start-upwith the discharge side gate valve slightly open, thefollowing limits may be used for orientation. These limits arebased on the assumption that start-ups are regularly spaced inthe period indicated.
Motor rating (kW) max. S (Start-ups/h)up to 12 15up to 100 10
above 100 5
If the above switching frequencies are exceeded, please con-tact the motor manufacturers or KSB.
6.2.3 Density of the Medium HandledThe power input of the pump will increase in proportion to thedensity of the mediumhandled. To avoid overloading of themo-tor, pump and coupling, the density of the mediummust complywith the data specified on the purchase order.
6.2.4 Abrasive MediaWhen the pump handles liquids containing abrasive sub-stances, increased wear of the hydraulic system and the shaftseal are to be expected. The intervals recommended for servi-cing and maintenance should be shortened.
6.2.5 Minimum/Maximum FlowUnless specified otherwise in the characteristic curves or on thedata sheets, the following applies:Qmin = 0.1 x Qopt for short operationQmin = 0.3 x Qopt for continuous operationQmax = 1.1 x Qopt for 2-pole operationQmax = 1.25 x Qopt for 4-pole operationQopt = optimum efficiencyThe data refer to water and water-like liquids. However, if thephysical properties of the media handled are different fromwater, the calculation formula belowmust be used to check if anadditional heat build-up may lead to a dangerous temperatureincrease at the pump surface. If necessary, the minimum flowmust be increased.

6.3.2 Measures to Be Taken for Prolonged Shutdown1.The pump remains installed; periodic check of operationIn order tomake sure that the pump is always ready for instantstart-up and to prevent the formation of deposits within thepump and the pump intake area, start up the pump set regu-larly once a month or once every 3 months for a short time(approx. 5 minutes) during prolonged shutdown periods.Prior to an operation check run ensure that there is sufficientliquid available for operating the pump.
2.The pump is removed from the pipe and storedBefore putting the pump into storage carry out all checks spe-cified in sections 7.1 to 7.4. Then apply appropriate preserva-tives:- Spray-coat the inside wall of the pump casing, and in par-
ticular the impeller clearance areas, with a preservative.Spray the preservative through the suction and dischargenozzles. It is advisable to close the nozzles (for ex. withplastic caps or similar).
- If the pumps are out of service for more than 1 year, allelastomer seals must be replaced.
6.4 Returning to Service after StorageBefore returning the pump to service carry out all checks andmaintenance work specified in sections 7.1 and 7.2.
In addition, the instructions laid down in the sections on”Commissioning” (6.1) and ”Operating Limits” (6.2) must
be observed.Upon completion of the work, all safety-related and pro-tective equipmentmust be properly refitted and/or reacti-
vated before starting the pump set.
7 Maintenance / Repair7.1 General InstructionsThe operator is responsible for ensuring that all maintenance,inspection and installation work is carried out by authorized,duly qualified staffwho are thoroughly familiarwith these opera-ting instructions.A regular maintenance schedule will help avoid expensive re-pairs and contribute to trouble-free, reliable operation of thepump with a minimum of maintenance expenditure and work.
Work on the unit must only be carried out with theelectrical connections disconnected.Make sure that
the pump set cannot be switched on accidentally (dangerof life!).
Pumps handling liquids posing health hazardsmustbe decontaminated. When draining the medium see
to it that there is no risk to persons or the environment. Allrelevant laws must be adhered to (danger of life!).
7.2 Maintenance / Inspection7.2.1 Supervision of Operation
The pump must run quietly and free fromvibrations at all times.
The pump must never be allowed to run dry.Prolonged operation against a closed shut-off element isnot permitted. When running the pump with the
discharge-side shut-off element slightly open for a short period,the permissible pressure and temperature values must not beexceeded.
A special design is required to comply with temperatureclass T6 in the bearing area. In such cases, and if ambi-
ent temperature exceeds 40�C, contact the manufacturer.Verify correct oil level as described in section 6.1.1.The shut-off elements and the auxiliary feed lines must not beclosed during operation.Any stand-by pumps installed shall be switched on once aweekto keep them operational.Attention shall be paid to the correct functioning of the auxiliary
connections.The cooling system must be thoroughly cleaned at least oncea year to ensure proper cooling. Take the pump out of servicefor this purpose.
If the flexible coupling elements begin to showsigns of wear, they must be replaced in due time.

7.5.4 Mounting the Mechanical SealThe following rules must be observed when mounting themechanical seal:Extreme care and cleanliness during assembly are ofoverriding importance for trouble-free operation of themechanical seal.The protective wrapping of the contact faces shall only beremoved immediately before assembly takes place.After inserting the seat ring, check whether it is plane-parallel inrelation to the casing part.The surface of the shaft protecting sleeve must be absolutelyclean and smooth, and the sleeve’s mounting edge must bechamfered.When sliding the rotating unit onto the shaft protecting sleeve,
take appropriate steps to protect the shaft protecting sleeve’ssurface from damage.On single-acting mechanical seals with quench feed, parallelpin 562.03 shall be glued in (e.g. using Loctite).On pumps with double-acting mechanical seal the mechanicalseal chamber must be properly vented and the requiredpressure specified in the general arrangement drawingmust beapplied (also during standstill).Quench liquid supply must also be ensured during pumpstandstill.
7.5.5 Diametral Clearances between Impeller and CasingThe clearance gaps refer to the diameter!Discharge nozzle DN Clearance gap

8 Trouble-shooting
Cause Remedy 1)
* Pump delivers against an excessively high dischargepressure.
Re-adjust duty point.
* Excessively high back pressure. Check plant for impurities.Increase the speed (turbine, I.C. engine)
* * * Pump or piping are not completely vented or primed. Vent and/or prime.
* Supply line or impeller clogged. Remove deposits in the pump and/or piping.
* Formation of air pockets in the piping. Alter piping layout.Fit a vent valve.
* * * Pump is warped or sympathetic vibrations in piping. Check pipeline connections and secure fixing of pump; if re-quired, reduce the distances between the pipe clamps.Fix the pipelines using anti-vibration material.
* * * Suction head is too high/NPSH available (positive suctionhead) is too low.
Check/alter liquid level.Fully open shut-off valve in the suction line.Change suction line, if the friction losses in the suction lineare too high.Check any strainers installed/suction opening.Observe permissible speed of pressure fall.
* Increased axial thrust. 2) Correct rotor adjustment.
* Air intake at the shaft seal. Fit new shaft seal.
* Wrong direction of rotation. Interchange two of the phases of the power supply cable.
* * Motor is running on two phases only. Replace the defective fuse.Check the electric cable connections.
* Speed is too low. 2) Increase speed.
* Defective bearings. Fit new bearings.
* * * Insufficient rate of flow. Increase the minimum rate of flow.
* * Wear of internal pump parts. Replace worn components by new ones.
* * Pump back pressure is lower than specified in the pur-chase order.
Adjust duty point accurately.
* Density or viscosity of the fluid pumped is higher than sta-ted in the purchase order.
2)
* Use of unsuitable materials. Change the material combination.
* * Speed is too high. Reduce the speed. 2)
* Tie bolts/seals and gaskets. Tighten the bolts.Fit new seals and gaskets.
* Worn shaft seal. Fit new shaft seal.
* * Score marks or roughness on shaft protecting sleeve. Fit new shaft protecting sleeve.Fit new shaft seal/check the balancing line.
* Lack of cooling liquid or dirty cooling chamber. Increase cooling liquid quantity.Clean out cooling chamber.Purify/clean cooling liquid.
* Dismantle to find out. Correct.
* Vibrations during pump operation. Improve suction conditions.Re-align the pump.Re-balance the impeller.Increase the pressure at the pump suction nozzle.
* * * The unit is misaligned. Check the coupling; re-align, if required.
* Insufficient or excessivequantity of lubricant or unsuitablelubricant.
Top up, reduce or change lubricant.
* Non-compliance with specified coupling distance. Correct distance according to the general arrangementdrawing.
* Operating voltage is too low. Increase the voltage.
* Rotor is out of balance. Clean the impeller.Re-balance the impeller.
1) The pump pressure must be released before attempting to remedy faults on parts which are subjected to pressure.2) Contact KSB.
