If the pumps are correctly in-stalled and serviced we guarantee problem-free operation.This unit must be operated in strict compliance with the in-structions printed on the data plate relating to quantity, speedof rotation, pressure and temperature, and in linewith anyoth-er instructions outlined in the operating instructions or the or-der documentation. All instructions relating to electrical val-ues, installation and servicing must be strictly observed.Non-compliancewith these conditions during operation of theplant will lead to overloadingwhich could lead to pump failure.

The Discription and instructions within this operating manualrelate to standard design pumps and variants.If you cannot find all the information and instructions required,then contact the nearest KSB service agent.The data plate attached to the pump, Appendix 1 ”Generalpump outline” Fig. 1, gives the series/size, the most impor-tant operating data and works number/identity number, whichmust always be quoted when making enquiries, placing sub-sequent orders and especially when ordering replacementparts.In the case of damage please contact the nearest KSBservice agent or the manufacturing company.

2. SafetyThisoperatingmanualcontainsbasic instructions,whichmustbe observed during installation, operation and servicing.Therefore it is imperative that this manual is read prior to as-sembly by the fitter and relevant skilled staff/and operatorsand it must always be kept within the locality of the machine/plant.With regard to safety, not only those instructions listed underthemainheadingof safetymust beobserved, butalsoall otherspecial safety instructions which have been included underany othermain headingmust be strictly adhered to, for exam-ple for pumps privately owned.

2.1 Identification of symbols used within theoperating manual

The symbols contained within this manual calling attention tosituations where non-observance could endanger lives, arespecially identified such as:

Warning sign in accordance with DIN 4844 - W9

Calling attention to electric current with

Warning sign in accordance with DIN 4844 - W8

Safety instructionrelating tosituationswherenon-observancecoulddamage themachineand its functionsare identifiedwiththe word

Any instructions which are actually printed on the machinesuch as:

-- Arrow indicating direction of rotation-- Identification for fluid connections

must be observed without fail and be kept clean and legible.

2.2 Personnel skills and trainingOperators, fitters, service, inspection and personnel musthave proof of having the appropriate skills to carry out suchwork. Area of responsibility, allocation and supervision of thepersonnel must be controlled by the operator. Should the per-sonnelnothave the requiredknowledge, then trainingmustbearranged. If required the operator can arrange such training tobe carried out by the manufacturer/supplier. The operatormust also ensure that the instruction manual is fully under-stood by the personnel.

2.3 Dangerous practices -- non-observation of safetyinstructions

Non-compliance with the safety instructions can endangerpeople‘s lives, the environment and pumps.

In detail, non-compliance could, for example, cause the fol-lowing:

-- Failure of pump/plant to operate

-- Failure of servicing and maintenance methods

-- Endangering people by contact with electrical, mechani-cal and chemical matter

-- Contamination of the environment by leakage of danger-ous substances.

2.4 Safe working methodsThe operator must observe all safety instructions outlined inthis leaflet, the existing national safety precautions to preventaccidents, and also any inter-company working, operatingand safety regulations.

2.5 Safety instructions for operators

-- If hot or coldmachine parts are considered a danger, thenthese parts must be protected where contact is possible.

-- Safety equipment to prevent contactwith hot or coldmov-able parts must not be removed whilst the machine is inoperation.

-- Leakages (for example at shaft seals) of dangerous me-dia (e.g. explosives, poisonous, hot liquids) must be dis-posed of in such a manner as to avoid any danger to per-sonnel and environment. Official regulations must beadhered to (see paragraph 7.3).

5. Assembly/Installation

5.1 Safety regulations (flameproof)

Equipment to be installed in explosion dangerareas within Zone 1, must fulfil the fire protectionregulations.Details can be foundon the dataplate.When installing the equipment in explosion dan-

ger-areas within Zone 1, then the fire precautions and regula-tions set out in the PTB-test certificate have to be observedand adhered to. The PTB-test certificate must be kept withinthe location of operation (Foreman‘s Office).

5.2 Checking procedure prior to commencement ofinstallation

Construction lay-out must be in accordance with measure-ments set out on the table of dimensions.The construction of the base/concrete foundations should besufficiently strong (Min. BN 150) to ensure secure and func-tionally correct installation in compliance with DIN 1045 orequivalent standard can take place.

5.3 InstallationIt is imperative prior to installation of thepumps to check paragraph 5.3.1 of the

operatingdata,paragraph5.3.2 -- oil level control andalsoparagraph 5.5 -- direction of rotation.

Included in the items delivered there is a separate data plate,attached to the cable end, which gives the pump and motordata. This data plate must be fixed in a clearly visible positionoutside thesump (for example switchpanel, pipework,mount-ing bracket).

5.3.1 Checking of operating data

A check must be carried out to ensure that the details statedon the data plate agree with the order and pump data (for ex-ample operating voltage, frequency and pumped media tem-perature etc.).

5.3.2 Oil level control

The oil chambers of our submersible pumps have been filledwith environmentally friendly non-toxic paraffin oil of medicalstandard quality.The oil level must be checked prior to initial operation ofthe unit.

Procedure

Position the pump in accordance with ”General pump dia-gram” appendix 1, Fig. 3. Unscrew the plug 903.02 and gas-ket 411.03. The minimum oil level must not exceed ”M”.Should the oil level be lower then fill the oil chamber via thetapped hole until it overruns. See paragraph 7.2.5 for oil quali-ty and quantity. (Oil change)Tighten the plug with gasket.

5.4 Electrical connection

5.4.1 General

The electrical connection must be carried out by atrainedelectricianand in compliancewith local reg-ulations. Recommendation VDE 0100 and for fla-meproof equipment VDE 0165.The voltage must comply with the voltage indi-cated on the data plate.

Electrical installationmust be in accordancewith paragraph 9”Electrical installation lay-out” and ”performancelay-out” for the appropriate motor sizes.

The pump is delivered completely assembled with andincluding cable diameters 4x35 mm2. From cable diameter4x50 mm2 onwards electrical cables are supplied loose fortransport reasons, and they have to be installed prior to as-sembly as outlined in Appendix 2.1 ”General drawing ofcable connections” and Appendix 8 installation instruc-tions ”Cable entry”.

The protection cover which is situated atthe cable gland, should not be removeduntil immediately before installation.

The individual coresof the cableare identifiedby yellow identi-ty tags and black writing (for example U.V.W 21,22 or10,11,...).Should it be necessary to shorten the cable, then the printedcore numbers i.e. the core colours should be used as a guide.In such cases the yellow tags should be removed and thencorrectly re-attached to the shortened cores.

When laying an earth cable between thepumping station and the electrical switch

gear, then additional multi-core control cable (min. 1,5 mm2)must be installed for motor monitoring equipment and floatswitch control.Adjust cores to suit requirement.

When draining low lying equipment a non-return valve shouldbe fitted into the outlet pipe to avoid liquid being returned fromthe channel.

Within the flameproof area all electrical cablingmust be connected to earth with flameproof termi-nal boxes or approved cast resin sockets (in accor-dance with VDE 0165).

5.4.2 Electrical connection

5.4.2.1Monitoring equipment

The unit has been supplied with monitoring equipment to pre-vent overloading. Installation, description and functioning ofthemonitoring equipment can be taken fromAppendix 6 andAppendix 7.1 to 7.4 ”Electrical connections diagrams/cir-cuit diagrams temperature control”.

5.4.2.2Power connections

When the equipment is installed in explosion-danger areas,then provision has to be made for a potential equaliser. Thepotential equaliser conductor is connected to the terminalPartNo. 81-29.03 or support (yoke) part No. 81-11.01, 900.24,932.24 (Appendix 1 ”General pump outline” Fig. 4) whichis situated at the cable entry i.e. at the terminal box.

Special requirements for chemically corrosive corrosivemedia.

When the unit is used for chemically corrosive corrosive me-dia and with a flameproof pump then the connecting clampwhich is situated outside the unit must not be used.

Instead the potential equaliser should be fitted to a flange atthe outlet pipewhich does not come in contact with themedia.Please ensure that there is an electrical connection betweenthe newly created potential equaliser and the pump.

Procedure(Appendix 1 ”General pump outline” Fig. 5)1. Drill a hole diameter size 8,8 + 0,1 mm on the flange at the

outlet pipe which is not subject to pumped media admis-sion.

2. The end terminal 81-29 supplied should be dismantled andforced into the drilled hole using the tool provided.

3. Install earth terminal and connect potential equaliserconductor.

5.4.2.3Installation for frequency inverter operation

The given motor capacity of P2 can only be used up to 85%.With flameproof equipment a thermistor relay unit with resetfacility and PTB-certificate must be installed. (for exampleMessrs. SiemensType3UN6with reset facility).Other specialcharacteristics for this method of operation can be taken fromAppendix 6 and Appendix 7.1 to 7.4 ”Electrical connec-tions diagram/circuit diagram.

5.4.3 Fitting of electric cabling

During installation of the electric cabling it isadvised to position the motor supply cable

upwards and if possible fastened it to avoid it being affectedby the swirl created by the pumped liquid.

For correct installation of the electric cabling within thepumpsump (Appendix1 ”Generalpumpoutline”Fig. 5)werecommend using cable socks, which can be supplied as anadditional extra (paragraph 4.4). Slack installation of cablescould cause damage to the electric cabling during vibrationwhen the pump is operating.

5.4.4 Fitting cable protection sockIf the electrical connection cable is supplied inclusive of a sus-pension sock, then this must be installed prior to assembly incompliance with the operating instructions for ancillary equip-ment ”Suspension sock installation”.

5.4.5 Overcurrent relayThe motor has to be protected against overloading by a ther-mally retarded over-current relay to comply with VDE 0660.This should be adjusted to the nominal motor current as indi-cated on the data plate on the motor. The regulating value forstar delta is IN x 0,58. However, this only applies when the

overload relay between star delta combination andmotor hasbeen switched on.

5.4.6 Level control switch

Stations with automatic pump operation should be fitted witha level control switch. Cut-off control print should be adjustedto comply with Appendix 4 ”Dimensions Table” this willcause the pump to stop and avoid possible dry running.

5.5 Direction of rotationOnce the electrical connections are complete (paragraph5.4)the following should be noted:

Correct direction of rotation of the impeller isof utmost importance for problem-free oper-

ation of the pump. The pump cannot reach its duty point if thedirection of rotation is incorrect, vibrations and overheatingwill occur. There is the danger of causing damage to the plant.

Seen from the pump suction opening direction of rotationshould be anti-clockwise.

In addition there is an arrowon thepumpcasingpointing in thecorrect direction of rotation.If the correct phase sequence is know, then, if the connectionis carried in accordance with paragraph 5.4, correct directionof rotation of thepumpwill result automatically (anti-clockwiserotation of the motor).

Prior to carrying out any tests please check thatthere are no foreign bodieswithin the pumpcasing.Never put hands or any objects into the pump.

Do not permit the pump to dry run for longperiods -- brief switching on is permitted andshould not be dangerous.

Typical methods of controlling direction of rotation

1. Control via suction end opening(Appendix 1 -- ”General pump outline” -- Fig. 6)Whilst the pump is in the horizontal position briefly switchthe machine on and off. Observe direction of rotation ofthe impeller via the suction end opening. Rotation mustbe in the direction indicated by the arrow cast into pumpcasing.

2. Control via outlet brach opening(Appendix 1 ”General pump outline” Fig. 6)Put the pump securely in a vertical position and brieflyswitch on and off. Observe direction of rotation via theoutlet branch opening. Rotation should be in the directi-on indicated by the arrow cast into the pump casing.

If directionof rotation is incorrect, twoof the threephasesin the control panel must be changed.

1. Prior to lowering the pump fit claw 732 to the dischargeflange of the pump housing.The screws have to be tightened in accordance withinstructions. This is described under item 7.4.1 in thetable ”Bolt tightening torque”.

NOTE for KRT 80 -- 200100 -- 200

Prior to securing the claw insert butt strap 575.351) intothe slot on the outlet branch. Fit claw in such a way thatthe raised boss comes to rest against the back of theflange.1) Not applicable when supplied in special material.

Tighten hexagonal screw with a torque of 40 Nm(4mkp).To prevent loosening of the hexagonal screw the lockingwasher tab 901.35 should be bent upwards.

2. Fit profile seal 410.35 into the groove of the claw/pumpca-sing flange. This profile seal will serve to seal the duckfootbend during installation.

5.6.2.4Fitting of the mounting bracket/duckfoot bend/guide wire

Construction of the base/concrete foundations should be suf-ficiently strong (minimumDN150) toensurea functionally cor-rect fixing of the guide wire equipment and duckfoot bend.

Refer to the drawing as illustrated inAppendix 5.1 ”Wetwellinstallationstationarywithguidewirewithparts list‘ for allinstallation tasks outlined below.

1. Secure mounting bracket 894 using anchor bolt (dowels)90-3.37 at the sump opening rim. Drill hole diameter forbolts as illustrated in Appendix 4 ”Dimension Table”Fixing for pumps up to sizes 200-400 form part of the con-signment/order. For larger pumps all fittings and fixingshave to be specially ordered by the customer and they ha-ve to comply with construction and site conditions. For thebolt pattern of the mounting bracket refer to Appendix 4

”Dimension Table”.

2. Fit threaded bolt 904 with clamping piece 553/ supportpiece 572 to the mounting bracket. Do not unscrewhexagonal nut 920.36 too much, just enough to allowsufficient play for tightening thewire subsequently.Ensurethat the two clamping pieces 553 are fitted correctly to a

support piece.

3. The duckfoot bend should be positioned and secured tothebaseof the sumpso that later the tightenedwirewill runvertical.Should construction/pipework etc. require the wire to runoff the vertical, then amaximum angle of 5o should be ad-hered to thus ensuring safe fitting function.Securing of theduckfoot bend is carried out by using bolts or foundationbolts regardless of pump size or material variation.

Units larger than approx 2000kg in weight are suppliedcomplete with foundation slide rails. Refer to Appendix 4”Dimension Table” andAppendix 5.1 ”Wet well instal-lation stationary with guide wire with parts list” for de-tails relating to appropriate fitting instructions and hole di-mensions.

4. Insertionofwireand fitting.Pushupclamping piece(s) 553and insert one end of the wire. Lead the wire around the

duckfoot bend 72-1 and back again towards the guidebracket and insert into clamping piece(s) 553. Manuallytension the wire and secure using clamp(s) 553.

5. Tighten the wire by fastening the hexagonal nut 920.36situated on top of the mounting bracket(s). Tighten thehexagonal nut with a torque of MA as outlined in the tableAppendix 5.1.1 ”Guide wire tension” to achieve suffi-cient wire tension. Subsequently secure by using secondhexagonal nut.

6. The loose end of the wire at the support piece 572 caneither be twisted into a ring or the end can be cut off. Afterlength adjustment seal off ends to avoid fraying.

5.6.2.5Fitting of chain / lifting wire stationary wet wellinstallation

Installation of this equipment should be carried out in accor-dance with ”General pump outline” Fig. 2a by inserting thechain/liftingwire into the loop opposite the outlet branch. Furt-her details can be found in ”Wet well installation stationarywith guide wire with parts list”.

This type of fixing achieves a forward inclination of the pumptowards theoutlet branchandpermits fittingpump to theduck-foot bend.

5.6.2.6Installation of the pump(”General arrangement of installation parts” Fig. 1)Guide the pump from above over the support piece 572 andthread into the guide wire, then lower slowly.

After lowering the pump it will fasten itself to the duckfoot bend72-1 and it is then ready for operation and connected to theinlet pipe.

5.6.2.7Connection of the pipeline(”General arrangement of installation parts” Fig. 1)Thedischarge pipe should be connected to the duckfoot bendwithout stress (i.e. not putting any load onto the flange).To avoid backflow from the delivery main whilst draining thesump non--return valve must be fitted into the discharge pipe,which is taken over and above the back-flow level and onlythen led into the sewage channel.In addition it is necessary to fit non--return valve for longer ri-sing pipes, to avoid increased back-flow when the pump isswitched off. For ventilation reasons this non--return valveshould not be fitted immediately on the duckfoot bend. For fit-ting suggestions refer to the abovementioned appendix. If fit-ting on the duckfoot bend cannot be avoided, then drill a venti-lation hole into the duckfoot bend.

6 Start up/shut down

KRT submersible pumps are constructed to ensure long andtrouble·free operation under normal operating condition.To achieve this it is important to fulfil the following require-ments. Any damage incurred as a result of non-compliance isnot covered by the guarantee.

6.1 Initial start up of pump

Prior to starting the pump it has to be ascertained that the fol-lowing points have been checked and executed:

Operatingdataparagraph5.3.1,oil level paragraph5.3.2and direction of rotation paragraph 5.5must be checked.

-- Ensure that all electrical equipment including all safetyequipment have been connected in accordance with in-structions, and that they comply with ”Electrical con-nections diagram/circuit diagrams (see also para-graph 5.4)The winding temperature control can only function, if thetemperature circuit is installed in accordance with”Electrical connections diagram/circuit diagrams”.Flameproof equipment is only guaranteed when bothtemperature circuits have been connected.

-- Ensure that the pump has been installed correctly tocomply with installation kit paragraph 5.1/5.2.

-- Should the pumphavebeenout of service for a long peri-od, then the steps outlined in paragraph 6.3must be car-ried out.

6.2 Limitations of operating range

6.2.1 Minimum liquid level

The pump is ready for operation when the liquid level hasreached measuring mark ”R”.This minimum liquid level also applies for pumping stationswith automatic pump operation.l”General pump outline” Fig. 7)

”R” = Lowest switch off point for automatic operation

”M” = Minimum liquid level for constant operation

Built-in temperature controls within the winding will protectthe motor from overheating. If the motor overheats (for ex-ample during long operationwith a completely exposedmo-tor) then the built-in temperature controls will switch off themotor and turn it on again automatically after cooling down(see paragraph 5.4 electrical connections). Protectionagainst dry operation which causes the pump to be auto-matically switchedoff (cut-off contact)must carry a full guar-antee covering technical controls. (Paragraph 5.4.6)

Dry running leads to increasedwear andtear and should be avoided.

6.2.2 surroundings

KRT .... type X,Y flameproof 40 OCKRT .... type U non-flameproof 1) 40 OC or as indicated

on data plateKRT .... type W non-flameproof 1) 60 OC or as indicated

on data plate1) Can be operated up to 80oC for a limited period (3-5mins. or until

the thermal protection equipment is activated)

Do not operate the equipment at tempera-tures higher than those indicated above.

Only if the manufacturer has given written consent. Damagecaused due to non-observation of this warning will not be cov-ered by the guarantee.

6.2.3 Switching frequencyIn order to avoid intolerably high temperature rises within themotor and excessive overloading of motor, seals andbearings, the following number of switching operations perhour (S) should not be exceeded:

Motor capacity(kW)

max. S(Switching operations/h)

up to 12 30

up to 100 20

over 100 10

6.2.4 Operating voltageThe greatest permissible deviation from the operating voltageis:-- non-flameproof equipment � 10%-- flameproof equipment � 5%of the nominal voltage. The maximum current difference be-tween the individual phases is 1 %.

6.2.5 Density of pumped media

Power input of the pump is increased depending on the densi-ty of the pumpedmedia. To avoid overloading of themotor thisdensity must comply with the data stated on the order

6.2.6 Abrasive media

When pumping media containing abrasive particles, then in-creased wear and tear of hydraulic and mechanical sealsmust be expected. Themaintenance intervalsmust be halvedfrom those usually recommended (as outlined in paragraph8). In addition it is recommended to limit the flow velocity in re-lation to the rising main to > 1,5 m/sec < 5 m sec in order toachieve the longest possible operating periods.

6.3 Shut down/storage/conservation

Every KRT pump has been carefully checked with regard tofittings prior to leaving the factory. If operation is not requireduntil some time after delivery, then we recommend the follow-ing steps for storage of the pump:

6.3.1 Storage of new pumps-- Spray the insideof the pumphousingwithoil payingspe-cial attention to the area around the impeller gap. Sprayoil through inlet and outlet branches. It is then recom-mended to protect the branches (with plastic caps orsimilar).

-- Store the pump in anupright position in a dry place. Sup-portall electrical cablesat cableentrypoints toavoidper-manent distortion.

-- Electric connecting cables are capped securely for pro-tection purposes prior to delivery. This protection mustnot be removed.

6.3.2 Measures for prolonged shut down periods

1. The pump remains installed ready for operationwhen required.In order to secure pump availability as and when re-quiredand toavoid formationofdepositswithin thepumpand the immediate pump surroundings, the plant shouldbe switched on for brief periods (approx 5minutes) onceevery month to three month as required. It is essentialthat there is enough pumped media in the inlet area orthat enough liquid can be fed into the pump.

2. The pump is dismantled and storedPrior to storage the pump should be checked and main-tained inaccordancewithparagraph7.1and7.2.Subse-quently the tasksoutlined inparagraph6.3.1must beun-dertaken to ensure the pump does not deterioratestorage.

6.4 Re-starting pump after storagePrior to re-starting operation of the pump all checks andmain-tenance steps outlined in paragraphs 7.1 and 7.2 have to becarried out.

In addition free-running of the impeller should bechecked. This can be done by putting a handinto the pump casing andmanually turning theimpeller.When restarting operation the items out-

lined in ”Initial operation” paragraph 6.1 and ”Operatinglimits” paragraph 6.2 have to be observed.

Immediately after completion of the mainte-nance work all safety and protection equip-ment has to be installed efficiently and seen in

operation.

7. Service and maintenance

7.1 General instructions

The operator must ensure that all maintenance, inspectionand repair work is carried out by qualified, authorised staff,whoare familiarwith theequipment andwhohave read theop-erating instructions.By compiling a maintenance plan it is possible to cut mainte-nanceexpensesandavoidextensive repaircosts thusachiev-ing trouble-free and reliable operating of the pump.

Always disconnect all electricity supplies priorto working on the pump. Safeguard the pumpfrom being started accidentally.The pumphas to be lifted out of the sump for all

maintenancework, securelyplacedona level surfaceandprecautions taken to prevent the pump falling over.

If the pumped media is hazardous, then thepump must be decontaminated. Special careshould be taken to prevent endangering per-sonnel and environment when draining leak-

age liquid/oil. All official regulations must be adhered to.

7.2 Service/Inspection

The following pointsmust be observed to ensure reliableoperation:

Item Maintenance tasks Maintenanceto be carriedout at follo-wing intervals

7.2.1 Insulation resistance check7.2.2 Visual inspection of electric cables

7.2.3 Check function of control equipment

7.2.4 Control of the leakage chamber

7.2.5 Oil change

7.2.6 Bearings and lubrication

7.2.7 Visual check of lifting chain

lifting wire every 5 years

7.2.1 Insulation resistance check

The insulation resistance of the motor winding has to bechecked every 4000 hours but at least once a year duringgeneral maintenance.

Measurements should be taken at cable ends (disconnectedin thestarter unit). The insulation resistanceof themotorwind-ing with cable ends U, V, W against measurements must notbe less than 5M�� Measurements should be taken using amegger of 1000V. If measurements are less than 5M�� thencableandmotormust bechecked separately.During themea-surement procedure the electric connection cable must bedisconnected from the motor.

!

Attention

Amarex KRT

13

Should the insulation resistance of the electric cabling proveinadequate, then this indicates that it is damaged and needsrenewing. Inadequate readingof the insulation resistanceval-ues of the motor indicate moisture or water penetration. If thisis the case then the manufacturer should be contacted.

Temperature monitoring circuits shouldnot be tested with a megger. Testingshould only be done with an Ohmmeter.

7.2.2 Visual inspection of the electric cables

Whenever the pump is inspected the electrical supply cablesshould also be checkedwith regard to damagesuchascracksor bubbles -- due to either mechanical or chemical causes. Ifthere is such damage then the electric cables must be com-pletely replaced.

7.2.3 Checking functions of control equipment

The performance tests should form part of generalperiodicmaintenancework, carried out every 4000 hoursor at least annually.The following performance tests require the pump to be atroom temperature.Theelectric supply cable to themonitoringequipmentmust bedisconnectedat the starter unit.Measurementsmust be takenwith a Ohmmeter at the relevant cable ends. If resistance val-ues for the subsequent performance tests are not achieved,then the electric supply cable must be disconnected from thepump and a second testmust be taken at the appropriate con-nections in the pump.

7.2.3.1Thermal motor monitoring

Themotor winding is protected against overheating by built-intemperature sensors. Refer to performance layout ”Thermalprotection monitoring” for relevant data. The test is carriedout with a Ohmmeter at the disconnected ends.If the laid down resistance valuesare exceeded, than this indi-cates defective temperature sensors.To rectify the fault the following steps should be taken:

From motor sizes 224.../246.../198.../4310...

For these sizes the sensors are within the motor windingand theymust be renewed to replace the defective circuit.

7.2.3.2Thermal monitoring of bearing on pump

From motor sizes 2104.../1386.../1268.../10710...

The bearing on the pump end is monitored by a PT 100 tem-perature sensor which is fitted into the bearing housing.

For instructions relating to performanceand technical data re-fer to performanceplan ”Ball bearing temperaturemonitor-ing”.The Test is carried out with a Ohmmeter between the discon-nected cable connections 15 and 16. If a temperature gaugeis functioning correctly, then the reading during a test shouldbe 108� + 10%. If the resulting value deviates considerably,thePT100gauge sensor should be renewed. The gauge con-trol has been screwed into the bearing housing and can be re-newed by an original replacement part.

If the value read by the gauge lies within the tolerance limits,but the release unit has switched off the pump, then test theball bearing and if necessary renew.

7.2.3.3Moisture protection electrode

Themotor area is protectedbyamoistureprotectionelectrode(Part No. 69.6) which has been fitted within the enclosure ofthe motor. This protection electrode is not always supplied asstandard.Core identification9will indicatewhether it hasbeenfitted or not. For details regarding performance and technicaldata refer to performance plan”Moisture detectionmonitoring”.The test is carried out by using a Ohmmeter between the dis-connected cable 9 and earth.

If the resistance is>150k�, then themoistureprotectionelec-trode is working correctly. Lower values indicate moisture orwater penetration into the motor. In this case, open the motorand service.

After dismantling of the pump the moisture sensor should beoverhauled or exchanged. The sensor can be restored by dry-ing it in an oven at a temperature of 120 oC for approximately1 hour. This should be followedbysoaking thesensor in trans-former oil.After drying the resistance should be 300-500 M�.Salt water contact will render the drying process ineffective.

A NEW MOISTURE SENSOR MUST BE FITTED IN THEEVENT OF DAMAGE.

7.2.3.4Monitoring float switch

From motor sizes 414.../286.../258.../4310...

The mechanical seals are controlled by a float switch(Part No. 81-45) which is fitted in the leakage chamber. Fordetails relating to performance refer to ”General pump out-line” Fig. 9, and for technical data refer to performance plan

”Mechanical seal monitoring”.Tests are carried out by usingaOhmmeter between coreends3 and 4.

Attention

Attention

Amarex KRT

14

If there is no moisture in the leakage chamber, then the resis-tance reading between core ends 3 and 4 must the less than10�.If the reading is ”infinitive” then this points to moisture in theleakage chamber. If checking of the leakage chamber as out-lined under paragraph 7.2.4 results in no moisture reading,then the float switch is defective and must be renewed.

7.2.4 Control of the leakage chamber

from motor size 414,.../286,.../258,.../4310,....

Whenever the pump is being serviced the leakage chambershould also be checked. Checking the leakage chamber willconfirm the performance of the mechanical seals.

If the pump has been used to pump haz-ardousmedia, thencare shouldbe taken

when emptying the leakage liquid to avoid danger to ei-ther personnel or environment. Always observe and ad-here to Government regulations.

Procedure:(Appendix 1 ”General pump outline” Fig 8)Put the pump in avertical positionand remove the plug903.04with seal 411.04. Note the plate ”drainage of leakage fluid”fitted next to the sealing plug. If no liquid runs out or, after sev-eral years of operation, only a small amount leaks out (lessthan 1 litre) then the mechanical seals are in order. If morethan 1 litre leakage liquid drains out then this indicates that themechanical seals are defective and must be replaced.

7.2.5 Oil change

The oil chamber of our submersible pump has been filled withenvironmentally friendly non-toxic paraffin oil ofmedical quali-ty on the pump end.However, the oil should be changed after 4.000 operatinghours, but at least annually.

Pumped liquid might enter the oil chamber when itis warm after operation, which can cause thepressure to rise within the chamber. It is thereforeadvisable to cover the filling plug 903 (with a cloth)during the opening process, to avoid hot liquid(squirting out) escaping.

Procedure:(Appendix 1 ”General pump outline”Erect the pump as shown inFig. 10 and put a suitable contain-er under the plug. Remove filling plug 903.03 with gasket411.03 and 903.05/411.05 ”oil drainage” plug and drain theoil.For sizes KRT 600-520, KRT 600-710 use a hand pump todrain the oil, which is supplied as part of the pump set. Thesuction tube of the hand oil pump is inserted into the oil drain-agehole (identifiedbyan instructionplate ”oil-drainage”) un-til the suction tube touches thebottomof theoil chamber.Thenpumpout theoil andcollect in a container for the following test.

Paraffin oil is light in colour and transparent in appearance. Aslight discolouring, caused by running in of new mechanicalseal or small leakage of dirt via the pumped media has no ad-verseeffects.Severe contaminationof theoil by thepumpme-dia however, indicates damaged mechanical seals. In this in-stance replace the mechanical seals.Replace plug 903.05 and fit new gasket 411.05.

RefillingErect the pump as demonstrated inFig. 3 and fill the oil cham-ber with oil until it overflows (see also paragraph 5.3.2). Re-place the plug 903.03 and fit a new gasket 411.03.

Quantity of oil:

Details regarding quantity of oil can be taken from the table inparagraph 7.6 ”Lubrication instruction”

Recommended quality of oil:

Trade name:Paraffin-oil free flowing Messrs. Merck No. 7174 or similarmanufacture of medical quality, non-toxic.This quality is harmless and as such complies with the regula-tions applicable to food.

Alternative:All non-alloyed and alloyed motor oils of classes SAE 10Wcan be used for lubrication of the mechanical seals. With re-gard to disposal all general Government regulations must beobserved.

Regional regulations have to be observed tothe extent that the oil does not contaminate

the pumped media /for example drinking water) and that safedisposal is guaranteed. Failing this it is not permitted to fill thepump with oil but paraffin oil must be used for this purpose.

7.2.6 Bearing and lubrication

The pump/motor shaft is supplied with grease lubricated ballbearings.

Up to motor size ...624/...646/...548These ball bearings are maintenance free and permanentlylubricated.Re-lubrication is not required.

From motor sizes 784.../806.../678.../4310...Thesemotor sizeshave roller bearingswhichhavebeen lubri-cated using grease.Water tight encapsulated lubrication nipples enable re-lubri-cation of the bearing from outside.Re-lubrication should be carried out after 4000 operatinghours, or at least annually.

Relubrication must be carried out whilstthe machine is running

Operation of the machine should be as brief as possible, butnot longer than three minutes.

Connect electrical supply to themachine for a briefperiod. Prior to switching on ensure that the pumpisstandingsecurely ona level surfaceandguardedagainst falling over.

It should also be checked that no loose objects are within thepump casing.Never put hands or objects inside the pump.

Grease quality: Lithium complex grease of hightemperature resistance quality.

Recommended commercial greases:ESSO UNIREX N3FAG ARCANOL L40TEXACO HYTEX EP3 / DEA Paragon

Grease quantity: Details regarding quantity of greaseusedfor lubrication canbe taken from the tablein paragraph 7.6 ”Lubrication instruc-tion”.

7.2.7 Visual check of lifting chain/lifting wire

Maintenance checks to the pump should also include the lift-ing chain/liftingwire inclusive of fitting to the pumpwith regardto possible damage -- caused either mechanically or chemi-cally. Damaged parts must be replaced by manufacturer‘soriginal replacement parts.This also refers to the correct fixing the lifting chain/lifting wireto the pump.

7.3 Dismantling and re-assembly

7.3.1 Basic guidelines and instructions

All repairs and maintenance work to the pump must only becarried out by specially trained staff and original replacementparts must be used.

The safety precautions as outlined in paragraph 7.1 haveto be observed. Paragraph 7.3.4 must also be taken into ac-count when dealing with flameproof equipment.

If the pump has been used to pump hazard-ous media, then care must be taken that,

whendraining the leakage liquid/oil filling,personnel andenvi-ronment are not endangered. All Government regulationshave to be observed.

Dismantling and re-assembly may only be carried out inline with the appropriate drawing. The sectional drawingand other instructions should be taken from the appen-dix. The dismantling sequence should be as outlined inthe sectional drawing.Our Service Department will always assist in overcomingproblems.

7.3.2 Preparing for the dismantling operation

Prior to dismantling the oil chamber as outlined in paragraph7.2.5.

If the pumphas a leakage chamberparagraph7.2.4 -- then theleakage chambermust be checkedwith regard to leakage liq-uid -- and if necessary it must be drained.Theunitmust not beput in ahorizontal position for thedrainingprocess until the plug 903.03 has been opened.(SeeAppendix 1 ”General pump outline”, Fig 6). Take note ofthe instruction plate ”Draining of leakage liquid” which hasbeen fitted next to the plug. The pump then has to be turnedover so that the leakage draining hole is on the underside topermit draining of any possible leakage liquid.

7.3.3 Dismantling the pump section

Dismantling of the pump section is carried out as illustrated inthe drawing (see Appendix 2 ”Sectional drawing with partlist”). To facilitate stripping of the pump casing(part no. 101) from the intermediate casing (part no. 113) jack-ing screws have been fitted, which have been sealed off withplastic stoppers. Special tools are not required. The only ex-ceptions relate to the impeller dismantling/assemblypro-cess for the following sizes.

8. FaultsUnit not pumpingPump delivers insufficientlyCurrent/power consumption too highHead too lowPump operation is uneven and noisy

Cause Remedy:Prior to carrying outwork to the pressure containing parts-- release pressure from the pump!Disconnect power supply to the pump.

Pump delivers against excessively high discharge pres-sure

Open discharge valve further until duty point is reached

Valve in discharge pipe not fully open Open gate valve completelyPump not running within operating limits Check operating data of the pump

Pump and/or pipeline are not completely vented or pri-med

Vent -- by lifting the pump off the duckfoot bend and lowe-ring it back again.

Pump inlet blocked by deposits Clean inlet, pump parts and non return valveInlet pipe or impeller blocked -- rotor running sluggishly Remove deposits from within the pump and/or pipelines

Dirt/fibres in impeller chambers Check impeller ensuring that it rotates slightly -- if neces-sary clean hydraulic

Wear of internal pump parts Replace worn partsDamaged column pipe (pipe and seal) Replace defective column pipe

Renew sealsUnacceptableairorgascontentwithin thepumpedmedia Contact your nearest authorised KSB agent

Oscillations caused by plant Contact your nearest authorised KSB agentWrong direction of rotation Switch two phases of the circuit cabling

Insufficient operating voltage Check electric supplyCheck cable connections

Motor not running due to no voltage supply Check electrical installationInform electrical company

Motor running on two phases only Replace defective fusesCheck electric cable connections

Motor winding or electric cable defective Replacebyneworiginal KSBcabling or contact yournea-rest authorised KSB agent

Radial bearing in the motor defective Contact your nearest authorised KSB agentWith star delta connection -- Motor only running in star po-sition

Check star delta connection

Water level dropping excessively during operation Check supply and capacity of system -- (sump depth)check level control

Temperature monitor for winding control has ceased tooperate due to excessively high winding temperature

Themotor will switch on automatically after cooling down

Thermistor release unit without automatic restart faclityfor temperature limit (flameproof) has been released dueto exceeding the permissible winding temperature

Check the pump. <in emergencies the unit can be swit-ched on by hand.

Motor has been switched off via the release unit whichmonitors temperature limits for the pump side ball bea-ring, because the permissible temperature of the lowerball bearing has been exceeded.

Performance check for thermal control on the pump sideball bearing as outlined in paragraph 7.2.3.

Moisture protection relay has been releasedMoisture within the motor

Check the pump(Only if fitted with moisture protection electrode)

Control circuit for the leakage chamber (ante-chamber)has been triggered

Performance test of the float switch as outlined in para-graph 7.2.3 and checking of the leakage chamber as out-lined in paragraph 7.2.4.

Attention: If working inside the pump is necessary whilst the pump is underwarranty, then contact your nearest authorisedKSBagent prior to commencement of work.

Description -- non--flameproof thermal cutout

Thewinding is protected against overheating by a temperaturecontrol circuit.

Three PTC- thermistors R1, R2, R3 (identification tape 10, 11)are used for temperaturemonitoring. They switch off the pump-set as soon as the maximum winding temperature is reachedand automatically switch it on again after the winding has coo-led down.

This means that a thermistor control unit ”T” (see fig. 1) withoutinterlocking for automatic re-start is required in the motor con-tactor. Any proprietary make can be used.

The bimetal switches F4, F5 (identification tape 20, 21) are notrequired and should be connected to dummy terminals.

Funktionsbeschreibung der Wicklungstemperatur-Über-wachung KRT mit Ex-Schutz (siehe auch Anschlußplan)Bei Ex-Schutz wird dieWicklung durch zwei unabhängige Temperatur-Überwachungskreise geschützt.

Als Temperaturwächter dienen zwei Bimetallachalter F4, F5 (Ader-kennband20 ,21) , welchediePumpebeimErreichendermax. zulässi-genWicklungstemperaturabundnachAbkühlenselbsttätigwiederein-schalten.

Dies erfordert, daß sie direkt in denSteuerkreis desMotorschützes ge-schaltet werden.

Zusätzlich sind als Temperaturbegrenzer nochmals 3 PTC-KaltleiterR1, R2, R3 (Aderkennband 10, 11) eingebaut, welche die Pumpe beimeventuellenVersagenderTemperaturwächterabschalten,bevordie fürden Ex-Schutz zulässigen Grenztemperaturen überschritten werden.Eine automatischeWiedereinschaltung ist hierbei nicht zulässig. Dieserfordert im Steuerkreis des Motorschützes ein Thermistor--Auslöse-gerät ”T” (siehe Fig. 1) mit Wiedereinschaltsperre.

Dies ist ein handeslübliches Gerät bzw. kann auch über KSB bezogenwerden.

Beim Umrichterbetrieb muß ein Auslösegerät mit dem Prüfzeichen”PTB3.53-PTC/A2” verwendet werden.

Nach Abschaltung durch die Temperaturbegrenzer ist eine Revisionder Pumpe notwendig. In drengenden Fällen kann bis dahin (nach Ab-kühlen der Maschine) eine Wiedereinschaltung von Hand vorgenom-menwerden. Ein Außerbetriebsetzen der Temperaturbegrenzer ist da-bei nicht zulässig.

DerExplosionsschutz für diePumpen ist nur gegeben,wenndie eingebauten Temperaturschalter (Temperaturwächerund Temperaturbegrenzer) mit den Adern 20, 21, 10 ,11 ge-mäß Bild angeschlossen sind

Twobimetal switchesF4, F5(identification tape20, 21)serveas tempe-raturemonitoring deviceswhich, as soonas themax.winding tempera-ture isreached, switch off the pumpandautomatically anagain after thewindings have cooled down.

This requires that the conductors are drectly connected to the controlciruit of the motor contactor.

Three PTC thermistor R1, R2, R3 (identification tape 10, 11) are fittedas additional temperaturecontrols which, in the event of temperatureswitch failure, shut down the pump before the temperature permissiblefor flameproof applications is exceeded.Automatic reset is not allowed.A thermistor control unit ”T” (see fig. 1) with manuell reset must be in-stalled in the control circiut of the motor confactors.

The thermistor control is a commercial product which can also be orde-red through KSB.

For operation with frequency converter, a release device bearing thetext mark ”PTB3.53--PTC/A2” must be used.

If the pump has been shut down by thermistors, it is necessary to over-haut it. in urgent cases the resetmaybeusedafter themotorhas cooleddown. The hermistors must not be made nonoperational at any time.

Flameproof requirements für the pumps are only compliedwith when built-in temperature monitoring devices (bime-tallswitchesand thermistors) includingconductors20, 21,10and 11 are connected up in accordance with fig.

Motor--Feuchtraum--Überwachung(siehe auch Anschlußplan)

Bei Feuchtigkeitseintritt in den Motorraum fließt über den ein-gebauten Feuchtigkeitsfühler ein Fehlerstrom von Klemme 9zur Masse. Dadurch wird ein Alarmsignal gleichzeitige Ab-schaltung der Spannung an Klemme 9 und/oder Abschaltungdes Motors durch einen FI--Schutzschalter F10 bewirkt. NachAuslösung des Schutzschalters ist eine Revision der Pumpenotwendig.Isolationswiderstandsprüfungen vornehmen:Bei Isolationswiderständen<5M�mußderMotor geöffnetundüberholt werden.Nach Demontage der Pumpe ist der Feuchtigkeitsfühler zu re-generieren oder auszuschalten. Regeneration ist durch Trock-nen in einemOfen, ca. 1Stunde bei 120 0C,möglich. Anschlie-ßend ist eine Tränkung in Transformatorenöl durchzuführen.

WIR EMPFEHLEN, NACH EINEM SCHADENFALL EINENNEUEN FEUCHTIGKEITSFÜHLER EINZUBAUEN.

Motor control / moisture detection

If water penetrates into the motor space, a fault current flowsfrom terminal 9 to earth via the built-in moisture sensor with theresult that an alarm is started and the voltage at terminal 9 issimultaneously cut and / or the motor is shut down through anFI protective switch (F10).After the protective switch has been activated, an overhaul ofthe pump is necessary.Carry out an insulation resistance test:If the insulation resistance is < 5 M� the motor has to be ope-ned, inspected and overhauled.After dismantling the pump restore or replace themoisture sen-sor. To restore the sensor dry it in an oven for about 1 hour at120 0 C. Thereafter soak it in transformer oil.

Description -- thermal monitoring of bearing

Thepump-siderollerbearing isprotectedagainstoverheatingbya temperature monitoring circuit. The built-in temperature sen-sor PT 100 (conductors with identification tapes 15, 16) in thebearing housing changes its resistance proportionally to thetemperature (fig. 2)Depending on the resistance a measuringtransformer switches to ”warning” , if there is a temperature in-crease and switches off the pump, if the temperature reaches adangerous degree (fig. 1).Themeasuring transformer is a commercial device, e.g. a prod-uct of the KRIWAN company, TYPE PT 100-2AV.Theadjustment of the device is carried out in the plant; thewarn-ing temperature is set at 110oC and the switch-off temperatureat 130oC.After the pump has been switched off due to an increase in thepump-side roller bearing temperature, an overhaul of the pumpis necessary.

Fitting of electric cables

The electrical cables are included, separately packed, andthey should be fitted and connected by a trained electrician asfollows:1.Remove the cover (see diagram 1). It is advisable to keepthis cover 160.01/160.02 in a safe place for possible lateruse. Remove junction box cover 81-22 (see general arran-gement drawing). Treat seals andmetallic sealing surfaceswith care! Do not score!

2.Cable cores are already identified. Cable gland 834.01/02and O-rings 412.07/08 to be fitted to the junction box cableentry (see diagram2). Remove the socket head cap screws914.04/05 and the O-rings 412.07/08 from the cover (seeItem 1 above) for the fitting of electrical cables. Should oneof theO-rings be damaged during removal then it can be re-placedbyoneof thespareones included in the junctionbox.Connect the cable coreswithin themotor junction box in ac-cordance with the core identification.Follow instructions set out in the Appendix with regardto method of connection.

3.After fitting the electric cableswithin the junction box it is ne-cessary to test theO-rings 412.07/08/09 at the cable glands834.01/03 with regard to leakage in the following manner.Remove hexagonal plug with joint ring 901.31/411.31(unit Y) and screw a test pipe G 3/8” into this opening (dia-gram 3).

With this test pipe and using 0.5 bar dry air (preferably nitro-gen) test the connection flangeof theelectrical cable for lea-kage for 5 minutes. Brush a little soapy solution or similaronto the connection flange.After this test secure hexagonal plug 901.31 with joint ring411.31.

Test pressure not greater than 0.5 bar.

4. In order to relieve stress on the cable gland 834.01/03 thepump is fittedwithacable support.Removal of the parts 825and 81-39.01/02 will make fitting of the cable as illustratedin diagram 4 possible.
