2.5.3 Potentially explosive environmentsUse explosion-proof pumps for applications inpotentially explosive environments.

The pump must not be used to pump ex-plosive, flammable or combustible liquids.

The classification of the installation sitemust comply with the local regulations.

Special conditions for safe use of ex-plosion-proof pumps:1. Make sure the moisture- and thermal

switches are connected in two sepa-rate circuits and have separate alarmoutputs (motor stop) in case of high hu-midity or high temperature in the motor.

2. Bolts used for replacement must beclass A4-80 or A2-80 according toEN/ISO 3506-1.

3. Contact the manufacturer if dimension-al information on the flameproof jointsis necessary.

4. During operation, the cooling jacket, iffitted, must be filled with cooling liquid.

5. The level of the pumped liquid must becontrolled by level switches connectedto the motor control circuit. Install anadditional level switch to ensure thatthe pump is stopped in case the stoplevel switch is not working.

6. Dry running is not allowed.7. Make sure the cable is mechanically

protected, attached to the switchboardand the cable bonding cannot slip out.

uct, make sure that the power supply isswitched off and it cannot be switchedon unintentionally.

DANGERCrushing hazardDeath or serious personal injury‐ During installation, always support the

pump by lifting chains or place it in hor-izontal position to secure stability.

CAUTIONCrushing hazardMinor or moderate personal injury‐ Do not put your hands or any tool into

the pump inlet or outlet after the pumphas been connected to the power sup-ply, unless the main switch has beenlocked in position 0.

‐ Make sure that the power supply can-not be switched on unintentionally.

The free end of the cable must not be sub-merged as water may penetrate into themotor.

Make sure that the pipes are installed with-out the use of undue force. No loads fromthe weight of the pipes must be carried bythe pump. Use loose flanges to ease theinstallation and to avoid pipe tension at theflanges.

4.1 Foundation

Foundations for pumps above 15 kWThe rotating equipment generates vibrations when animpeller or rotor is turning at high speed. Properinstallation and anchorage of the pumps andaccessories are crucial to limit vibrations and achievereliable installation:• The foundation and concrete must support the

weight of the pump including accessories, theliquid passing through the pump and the forcesgenerated by the pump.

• The mass of the concrete foundation must beminimum 3-5 times heavier than the weight of thesupported equipment and must have sufficientrigidity to withstand the axial, transverse, andtorsional loads generated by the pump.

• The foundation must be 15 cm wider than thebaseplate for pumps up to 350 kW and 25 cmwider for larger pumps.

• The concrete used in the foundation must have aminimum tensile strength of 250 N/cm2.

• Always use epoxy grout to fasten the baseplate tothe foundation.

Pumps with DN 250 or DN 300 flangesmust be installed on a concrete founda-tion.

the inside of the pit and fasten it provisionally withtwo screws.

2. Place the auto-coupling base unit on the bottomof the pit. If the bottom is uneven, the auto-coupling base unit must be supported. Use aplumb line to establish the correct positioning.Fasten the auto coupling with expansion bolts.

3. Connect the outlet pipe in accordance with thegenerally accepted procedures. Avoid exposingthe pipe to distortion or tension.

4. Place the guide rails on the auto-coupling baseunit and adjust the length of the rails to the guide-rail bracket at the top of the pit.

5. Unscrew the provisionally fastened guide-railbracket. Insert the expansion dowels into theholes. Fasten the guide-rail bracket on the insideof the pit. Tighten the bolts in the expansiondowels.

6. Clean out debris before lowering the pump intothe pit.

7. Fit the guide shoe to the pump.8. Slide the guide shoe along the guide-rails and

lower the pump into the pit by a chain secured tothe lifting bracket (fig. Lowering the pump alongthe guide rails). When the pump reaches the auto-coupling base unit, pull the lifting chain towardsthe guide rail several times to shake off anyforeign substances (fig. Connecting the pump toauto coupling). When the chain is unstrained, thepump connects automatically to the auto-couplingunit (fig.Submerged installation on auto coupling).

9. Hang up the end of the chain on a suitable hookat the top of the pit. Make sure that the chain isstraight but not strained.

10. Adjust the length of the power cable by coiling itup on a relief fitting to ensure that the cable is notdamaged during operation. Fasten the relief fittingto a suitable hook at the top of the pit. Make surethat the cables are not sharply bent or pinched.

11. Connect the power- and the control cables, if any.

The free end of the cable must not be sub-merged as water may penetrate into themotor.

5. Electrical connectionDANGERElectric shockDeath or serious personal injury‐ Before starting any work on the prod-

uct, make sure that the power supply isswitched off and that it cannot beswitched on unintentionally.

DANGERElectric shockDeath or serious personal injury‐ The pump must be grounded. Before

connecting the pump to the voltagesupply, make sure the connection toground complies withthe local regula-tions.

Connect the pump to an external mainswitch ensuring all-pole disconnection witha contact separation according to EN60204-1, 5.3.2. It must be possible to lockthe main switch in position 0.The supply voltage and frequency aremarked on the nameplate. Make sure thatthe motor is suitable for the power supplyat the installation site.The electrical connection must comply withthe local regulations.

Connect the pumps to a controller with amotor protection relay with IEC trip class10 or 15 or NEMA-equivalent.

The power supply for the motor protectioncircuit must be low voltage, class 2.

Connect pumps installed in hazardous lo-cations to a control box with a motor pro-tection relay with an IEC trip class 10.

1. Do not install pump controllers, Ex bar-riers or the free end of the power cablein potentially explosive environments.

2. The classification of the installation sitemust comply with the local rules.

3. On explosion-proof pumps, make surethat an external ground conductor isconnected to the external ground ter-minal on the pump by a secure cableclamp. Clean the surface of the exter-nal ground connection and mount thecable clamp.

4. The ground conductor must be mini-mum AWG 12 type RHH, RHW,RHW-2 or similar, rated for 600 V andminimum 90 °C, yellow and green.

5. Make sure that the ground conductor isprotected from corrosion.

6. Make sure that all protective equip-ment has been connected correctly.

7. Float switches used in potentially ex-plosive environments must be ap-proved for this application. They mustbe connected to the Grundfos Dedica-ted Controls, DC, DCD or the SLC,DLC controllers, by an intrinsically safebarrier to ensure a safe circuit.

If the power cable is damaged, it must bereplaced by the manufacturer or his serv-ice agent.

Connect the pump to a motor-protective circuitbreaker.

Set the motor-protective circuit breaker tothe rated current of the pump +15 % serv-ice factor. The rated current is stated onthe nameplate.

The supply voltage and frequency are marked on thenameplate.The voltage tolerance at the motor terminals must bewithin ± 10 % of the rated voltage.The motor is effectively grounded with the powercable and pipes. The motor top cover is equippedwith connections for external grounding or anequipotential bonding conductor.

Maintenance and service work on explo-sion-proof pumps must be carried out byGrundfos or an authorised service work-shop.

Before installation and the first startup ofthe pump, check the condition of the cableto avoid short circuits.

The most commonly used startup methods are thefollowing:• Direct-on-line starting (DOL). See Appendix, fig.

4.3.• Star-delta starting (Y/D). See Appendix, fig. 4.3.• Soft start.The selection of suitable starting method depends onseveral considerations on usage and mains supplyconditions.

When using star-delta start, it is importantto keep switching transient time to a mini-mum to avoid high transient torques. Usea time relay with a switching time of maxi-mum 50 ms or according to the manufac-turer's specifications.

The pump can be operated with a frequencyconverter according to the specifications of themanufacturer.

5.1 Frequency converter operation

If the motor is operated by a frequencyconverter, the temperature class of the ex-plosion-proof pumps must be T3.

In principle, all three-phase motors can be connectedto a frequency converter.However, frequency converter operation oftenexposes the motor insulation system to a heavier loadand may cause the motor to be more noisy due toeddy currents caused by voltage peaks.In addition, large motors driven with a frequencyconverter are loaded by bearing currents. In thisproduct range, only negligible amounts of bearingcurrents occur during the use of frequency converter.For frequency converter operation, observe thefollowing:• The thermal protection of the motor must be

connected.• Peak voltage and dU/dt must be in accordance

with the table below. The values stated aremaximum values supplied to the motor terminals.The cable influence is not taken into account. Seethe frequency converter data sheet regarding theactual values and the cable influence on the peakvoltage and dU/dt.

• The minimum switching frequency is 2 KHz. Theswitching frequency can be variable.

• If the pump is an Ex-approved pump, check if theEx certificate of the specific pump allows the useof a frequency converter.

• Set the frequency converter U/f ratio according tothe motor data.

• Before installing a frequency converter, calculatethe lowest frequency allowed in the installation toavoid zero flow.

• Do not reduce the motor speed to less than 50 %.

• Keep the flow rate above 1 m/sec.• Let the pump run at rated speed at least once a

day to prevent sedimentation in the pipe network.• Do not exceed the frequency indicated on the

nameplate as this may cause motor overload.• Keep the power cable as short as possible. The

peak voltage increases with the length of thepower cable.

• Use input and output filters on the frequencyconverter.

• Use a screened power cable if there is a risk thatelectrical noise may disturb other electricalequipment.

• Set the frequency converter for constant-torqueoperation. Pulse width modulation should beused.

When operating the pump by a frequency converter,consider the following:• The locked-rotor torque can be lower depending

on the type of the frequency converter.• The noise level may increase. See the installation

and operating instructions for the selectedfrequency converter.

5.3.1 Thermal switchesThree Klixon bimetallic thermal switches are built intothe stator windings. A contact opens in case ofovertemperature(150 °C). The motor insulation classis class H (180 °C).The supply voltage to the thermal switches must be12-24 V DC.The thermal switches are connected to the controlcable and must be connected to the safety circuit ofthe separate pump controller.Check whether the circuit resistance is maximum 3 Ωper thermal switch, with a multimeter.

The motor-protective circuit breaker of thepump controller must include a circuitwhich automatically disconnects the powersupply in case the protective circuit isopened.

In case the thermal switches or the mois-ture switches are not working, install anautomatic circuit breaker.

5.3.2 Moisture switches and leakage switches

Non-Ex version:One moisture switch and one leakage switch aremounted in a non-Ex pump. The moisture switch isplaced in the top cover and the leakage switch is inthe chamber above the shaft seal. See Appendix, fig.4.3, section C-C and E-E.

Ex version:One moisture switch and one leakage switch aremounted in an Ex pump. The moisture switch isplaced in the top cover and the leakage switch is inthe stator housing. See Appendix, fig. 4.3, section C-C and D-D.All switches in both non-Ex and Ex versions arehardwired from the pump to IO 113. If moisture or aleakage is detected, they break an electric circuit.This generates both a hardware and a software alarmin IO 113, and the alarm relay opens.Moisture and leakage switches are motor protectiondevices, which protect the motor from damage due tomoisture or leakage.The switches are non-reversingand they must be replaced after they have beenreleased.The moisture and leakage switches are connected ina separate circuit and to the control cable. SeeAppendix. They are also to be connected to thesafety circuit of the separate pump controller.

5.3.3 ThermistorsThe standard pump range has Klixon switchesconnected, however, a pump with PTC thermistorsconnected are available as a Factory ProductVariants (FPV).The thermistors can be used as motor protectiondevices to monitor stator temperature instead ofthermal switches and must be connected to thethermistor relay in the control cabinet.The operating voltage of PTC thermistors is 2.5 - 7.5V.Checks after electrical connection1. Check whether the circuit resistance is below 150

Ω per thermistor, with a multimeter.

2. Check whether the insulation between circuit andstator housing is outside the range, with amultimeter.

3. Carry out similar measurements at the end of thepower cable.

Pt1000 temperature sensorThe Pt1000 temperature sensor is available as anaccessory or an FPV.The Pt1000 sensor is primarily used for themonitoring of bearing temperature, but it can also beused in the stator.In case of overheating caused, the Pt1000 sensortrips an alarm and disconnects the power supply at apreset temperature.

The bearing temperature monitoring sys-tem is only available as an option.

The sensor resistance values are the following:• 1000 Ω at 20 °C• 1385 Ω at 100 °C• approximately 1078 Ω at room temperature.The temperature limits are the following:• 90 °C: warning for bearing temperature• 130 °C: pump stop caused by high bearing

temperature• 150 °C: pump stop caused by high stator

temperature.

In Ex-approved pumps, the maximum ac-ceptable alarm temperature in the bearingsensors is 100 °C for the lower bearing(shaft end) and 120 °C for the upper bear-ing.

Checks after electrical connection1. Check whether the resistance at room

temperature (20 °C) is approximately 1078 Ω, witha multimeter.

22

English (GB)

2. Check whether the insulation between the circuitand the stator housing is outside the range, with amultimeter.

3. Carry out similar measurements at the end of thepower cable.

During the pump check, the Pt1000 sensor must beconnected to a recording device.

5.3.4 Pump vibration sensor (PVS 3)The PVS 3 sensor monitors the vibration level toprotect the pump and the pipe network againstdamage.A change in the vibration level indicates an abnormalsituation. Make sure that a service inspection iscarried out before the pump or the pipe network isdamaged.

Pumps are fitted with S-tube® impellers.The S-tube® impellers are wet-balanced toreduce vibrations during operation. If thesepumps are started with the pump housingcontaining air, the vibration level can behigher than in normal operation.

SM 113The SM 113 module is used for collecting andtransferring sensor data. SM 113 works with IO 113through power line communication using theGrundfos GENIbus protocol.SM 113 collects data from the following devices:• 3 current sensors, 4-20 mA• 3 Pt1000 thermal sensors• 1 PTC thermal sensor• 1 digital input.

SM113 is fitted with a 2.7 kΩ resistor toavoid false sensor alarms in the IO113.

IO 113The IO 113 module is the interface between a pumpwith analogue and digital sensors and the pumpcontroller. The most important sensor data areindicated on the front panel.One pump can be connected to IO 113.With the sensors, IO 113 is a galvanic separationbetween the motor voltage in the pump and theconnected controller.IO 113 enables the following functions:• overtemperature protection• monitoring the sensors for analogue

measurement of:- motor temperature- pump vibrations- stator insulation resistance- bearing temperature

- moisture in motor• stopping the pump in case of alarm• monitoring remotely the pump through RS485

communication (Modbus or GENIbus).

Measurement of insulation resistanceIO 113 measures the insulation resistance between astator winding and ground:• resistance above 10 MΩ = OK• resistance between 10 MΩ and 1 MΩ = warning• resistance below 1 MΩ = alarm.

3 Impeller clearance

The following method is suitable for pumps in verticalposition. Proceed as follows:1. Loosen the fastening- and set screws so the

impeller is sitting on the suction cover / stationarywear ring. When the impeller is in this position, theimpeller clearance is zero.

2. Tighten the three set screws down by hand untilthey touch the top surface of the volute.

3. The impeller clearance is created by turning theset screws to a specified angle. Closed S-tube®

and open S-tube® impellers, as well as thedifferent head classes, have different impellerclearances. See the table above to determine thecorrect impeller clearance and turning angle.

4. Once the correct angle is identified, turn the setscrew clockwise by the specified angle. Use aturning gauge to ensure the set screw is tightenedto the correct amount.

5. Tighten the fastening screws in two steps,according to the sequence below:• Tighten the screws one by one, from 1 to 6.

Required torque: 40 ± 4 Nm.• Repeat the previous sequence to the final

torque of 70 ± 4 Nm

9. Troubleshooting



DANGERElectric shockDeath or serious personal injury‐ The pump must be grounded.

Before diagnosing any fault, make surethat all rotating parts have stopped mov-ing.

Observe all regulations applying to pumpsinstalled in potentially explosive environ-ments.Make sure that no work is carried out inpotentially explosive atmospheres.

Fault Cause Remedy

The pump does not start or stops withoutvisible cause. No power supply. Re-establish the power supply.

Start the pump manually.

The pump does not start or stops. The con-trol panel indicates that the motor-protec-tive circuit breaker or protection equipmentis tripped.

Missing phase. Re-establish all phases.

The pump is overloaded.If the fault does not disappearautomatically, find the cause andremedy the fault.

The impeller is clogged by im-purities. Clean the impeller.

The motor-protective circuitbreaker is set incorrectly.

Set the motor-protective circuitbreaker according to the ratedcurrent.

The thermal switches are trip-ped. Insufficient motor cooling. Re-establish the motor cooling.

The moisture switch in the mo-tor is tripped.

Contact an authorised serviceworkshop.

The power cable is defective. Contact an authorised serviceworkshop.

The voltage is fluctuating.Re-establish the correct voltagesupply. Permissible deviation is± 10 %.

The pump runs, but does not deliver therated flow.

The direction of rotation iswrong.

Interchange two phases to themotor.

The impeller is loose or worn. Tighten or replace the impeller.

The pump or the pipes areblocked by impurities. Clean the pump or the pipes.

The pump head is too high.

Measure the differential pres-sure and compare the value withthe pump curve. Check that allvalves are open or remove anyblockage in the outlet pipe.

The valves are closed orblocked. The non-return valveis not operating.

Clean or replace the valves.

(GB)

Fault Cause Remedy

There is air in the pump or theinlet pipe.

Vent the pump and the inletpipe. Increase the stop level inthe pit.

The pumped liquid is toodense. Dilute the pumped liquid.

The pump is improperly con-nected to the auto coupling.

Pump down the liquid level inthe pit. Lift out the pump andplace it on the auto couplingagain.

There is leakage in the pipes. Repair the pipes.

The pit flushing system is inad-vertently activated.

Check the function of the pitflushing system and repair it, ifrequired.

The pump starts, but stops immediately.

The pump is clogged, whichcauses the motor-protective cir-cuit breaker to trip.

Clean the pump.

The motor is overheated, whichcauses the thermal switches totrip.

Allow the pump to cool. Cleanthe pump.

The level switch is out of ad-justment or defective.

Clean or set the level switch orreplace them, if required.

The pump is vibrating or emitting excessivenoise.

The pump is partly clogged byimpurities. Clean the pump.

The direction of rotation iswrong.

10. Technical datapH valuePumps in permanent installations can cope with thefollowing pH values:

Material var-iant Installation pH value

Standard1) Dry and submerged 6-143)

Q2) Dry and submerged 6-143)

1) Cast iron impeller, pump housing and motor top.2) Stainless-steel impeller. Cast iron pump housingand motor top.3) For fluctuating pH values, the range is pH 4 to 14.

Density and viscosity of the pumped liquidDensity: 1000 kg/m3.Kinematic viscosity: 1 mm2/s (1 cSt).

When pumping liquids with a densityand/or a kinematic viscosity higher thanthe values stated above, use motors withcorrespondingly higher outputs.

Flow rateKeep a minimum flow rate to avoid sedimentation inthe pipe network. Recommended flow rates:• in vertical pipes: 0.7 m/s.• in horizontal pipes: 1.0 m/s.

Ambient temperature

For explosion-proof pumps, the ambienttemperature on the installation site mustbe in the range from -20 to +40 °C.

For non-explosion proof pumps, the ambienttemperature may exceed +40 °C for a short period(maximum 3 minutes).

Liquid temperature0 to +40 °C.For non-explosion proof pumps, the liquidtemperature may be up to 60 °C for a short period(maximum 3 minutes).

Explosion-proof pumps must never pumpliquids of a temperature higher than +40°C.

Operating modeThe pumps are designed for continuous operation.

Frequency of starts and stopsMaximum number of starts per hour is 20.

Installation depthMaximum 20 m below liquid level.

Solids sizeFrom 35 to 125 mm, depending on the pump size.

Enclosure classIP68.

Sound Pressure

Use hearing protection when workingnearby an installation in operation with asound pressure level above 70 dB(A).

Motor liquidThe motor is factory-filled with Grundfos SML3 motorliquid which is frost-resistant until -20 °C. The motorliquid helps to transfer the heat generated by themotor to the cooling chamber and to the pumpedliquid to pass on the outside of the pump.

Electrical dataThe supply voltage and frequency are marked on thenameplate.The voltage tolerance at the motor terminals must bewithin ± 10 % of the rated voltage.

11. Disposing of the productThis product or parts of it must be disposed of in anenvironmentally sound way.1. Use the public or private waste collection service.
