6. Operating conditions

6.1 Ambient temperature and altitude

The ambient temperature and the installation altitude areimportant factors for the motor lifeas they affect the life of thebearings and the insulation system.

If the ambient temperature exceeds the recommended maximumambient temperature or the installation altitude exceeds therecommended maximum altitude above sea level (see fig. 6),the motor must not be fully loaded due to the low density and

consequently low cooling effect of the air. In such cases, it maybe necessary to use a motor with a higher output.

Fig. 6 The maximum motor output depends on the ambienttemperature and altitude

Legend

Example:A pump with a 1.1 kW IE2 MG motor: I f this pump is

installed 4750 m above sea level, the motor must not be loadedmore than 88 % of the rated output. At an ambient temperature of75 C, the motor must not be loaded more than 78 % of the ratedoutput. If the pump is installed 4750 m above sea level at anambient temperature of 75 C, the motor must not be loadedmore than 88 % x 78 % = 68.6 % of the rated output.

6.2 Liquid temperature

-25 C to +140 C.

The maximum liquid temperature is stated on the pumpnameplate. It depends on the shaft seal chosen.

For EN-GJL-250 cast iron pump housings, local regulations maynot allow liquid temperatures above +120 C.

6.3 Max. operating pressure

Fig. 7 Pressures in the pump

The inlet pressure + the pump pressure must be lower than the

maximum operating pressure (p) stated on the pump nameplate.Operation against a closed discharge valve gives the highestoperating pressure.

6.4 Min. inlet pressure

Pay attention to the minimum inlet pressure to avoid cavitation.The risk of cavitation is higher in the following situations:

The liquid temperature is high.

The flow rate is considerably higher than the pump's rated flowrate.

The pump is operating in an open system with suction lift.

The liquid is sucked through long pipes.

The inlet conditions are poor.

The operating pressure is low.6.5 Max. inlet pressure

The inlet pressure + the pump pressure must be lower than themaximum operating pressure (p) stated on the pump nameplate.Operation against a closed discharge valve gives the highestoperating pressure.

6.6 Min. flow rate

The pump must not run against a closed discharge valve as thiswill cause an increase in temperature/formation of steam in thepump. This may cause shaft damage, impeller erosion, short lifeof bearings and damage to stuffing boxes or mechanical shaftseals due to stress or vibration. The continuous flow rate must beat least 10 % of the rated flow rate. The rated flow rate is stated

on the pump nameplate.6.7 Max. flow rate

The maximum flow rate must not be exceeded as otherwise thereis a risk of for instance cavitation and overload.

The minimum and maximum flow rates can be read either fromthe performance curve pages in the relevant data booklets orfrom a curve for a specific pump when selecting it in WebCAPS.

6.8 Shaft seals

* Maximum 60 C.

The operating range of the seals is described for two mainapplications: pumping of water or pumping of coolants.

Seals with a temperature range of 0 C and up are mainly used forpumping water, while seals for temperatures below 0 C are mainlyintended for coolants.

Note: Operation at maximum temperature and maximum pressureat the same time is not recommended as the seal life will bereduced and periodical noise will occur.

8. Mechanical installation

8.1 Preparations before installation

The contractor must inspect the equipment on delivery and makesure that it is stored in such a way that corrosion and damage areavoided. If more than six months will pass before the equipmentis put into operation, please consider applying a suitablecorrosion inhibitor to the internal pump parts.

Ensure that the corrosion inhibi tor used does not affect the rubberparts with which it comes into contact.

Ensure that the corrosion inhibitor can easily be removed.To prevent water, dust, etc. from entering the pump, all openingsmust be kept covered until the pipes are fitted. The cost ofdismantling the pump during start-up to remove a foreign objectcan be very high.

Mechanical shaft seals are precision components. If themechanical shaft seal of a recently installed pump fails, this willnormally happen within the first few hours of operation. The maincause of such failures is improper installation of the shaft sealsand/or mishandling of the pump during installation.

During transport, the pump must be fastened securely to preventdamage to the shaft and seal caused by excessive vibrations andknocks. The pump must not be lifted by means of the shaft.

8.2 Pump location

The pump should be sited in a well-ventilated, but frost-freelocation.

For inspection and repair, allow suitable clearances for pump ormotor removal.

Vertical installation

Pumps fitted with motors up to and including 4 kW require a0.3 m clearance above the motor.

Pumps fitted with motors of 5.5 kW and up require at least a

1 metre clearance above the motor to allow the use of liftingequipment.

Fig. 9 Clearance above the motor

Horizontal installation

Pumps fitted with motors up to and including 4 kW require a0.3 m clearance behind the motor.

Pumps fitted with motors of 5.5 kW and up require a 0.3 mclearance behind the motor and at least a 1 metre clearanceabove the motor to allow the use of lifting equipment.

NB pumps with base frame must have the same clearance aspumps with motors from 5.5 to 200 kW.

Fig. 10 Clearance behind the motor

8.3 Connection

Arrows on the pump housing show the direction of flow of liquidthrough the pump.

The pumps can be installed with the motor/pump shaft in allpositions between vertical and horizontal, but the motor mustnever fall below the horizontal plane.

Horizontal motors with feet must always be supported.

Fig. 11 Installation positions

It is advisable to fit isolating valves on either side of the pump asthis makes it unnecessary to drain the system if the pump needsto be cleaned or repaired.

8.4 Foundation of NB, NBG pump without base frame

We recommend that you install the pump on a plane and rigidconcrete foundation which is heavy enough to provide permanentsupport for the entire pump. The foundation must be capable ofabsorbing any vibration, normal strain or shock. As a rule ofthumb, the weight of the concrete foundation should be 1.5 times

the weight of the pump. The concrete foundation must have anabsolutely level and even surface.

Place the pump on the foundation, and fasten it. See fig. 12.

Fig. 12 Foundation

The foundation length and width should always be 200 mm larger

than the length and width of the pump. See fig. 12.The mass of the foundation must be at least 1.5 times the totalmass of the pump. The minimum height of the foundation (hf) canthen be calculated:

The density () of concrete is usually taken as 2,200 kg/m3.

In installations where noise-less operation is particularlyimportant, a foundation with a mass up to 5 times that of thepump is recommended. See also 8.7 Vibration dampeningonpage 23.

8.5 Foundation of NB, NBG pump with base frame

This section applies only to 50 Hz pumps as base frames are notsupplied for 60 Hz pumps.

We recommend that you install the pump on a plane and rigidconcrete foundation which is heavy enough to provide permanentsupport for the entire pump. The foundation must be capable ofabsorbing any vibration, normal strain or shock. As a rule ofthumb, the weight of the concrete foundation should be 1.5 timesthe weight of the pump.

The foundation should be 100 mm larger than the base frame on

all four sides. See fig. 13.

Fig. 13 Foundation, X = min. 100 mm

The minimum height of the foundation (hf) can then be calculated:

The density () of concrete is usually taken as 2,200 kg/m 3.

Place the pump on the foundation,and fasten it. The base framemust be supported under its entire area. See fig. 14.

It is important to prepare a good foundation prior to the

installation of the pump.NB, NBG pumps with base frame are always prepared forgrouting (grouting anchors welded onto the base frame).

For NB, NBG pumps with 2-pole motors 55 kW, grouting of thebase frame is mandatory in order to prevent vibration energy fromthe rotating motor and liquid flow to evolve.

1: Preparing the foundation

We recommend the following procedure to ensure a goodfoundation.

2: Levelling of the base frame

Step Action Illustration

1

Use an approved, non-shrinking concrete. (Contact yourconcrete supplier for advice if any doubts.)Pour the foundation without interruptions to within19-32 mm of the final level. Use vibrators to ensure thatthe concrete is evenly distributed. The top surface should

be well scored and grooved before the concrete sets.This provides a bonding surface for the grout.

2Embed foundation bolts in the concrete. Allow enoughbolt length to reach through grout, shims, lower baseframe, nuts and washers.

TM0301904707

3Let the foundation cure for several days before the baseframe is levelled and grouted.


1Lift/jack up the base frame to the final level 19-32 mmabove the concrete foundation, and support the baseframe by means of blocks and shims both at thefoundation bolts and midway between bolts.

TM0451832809

2Level the base frame by adding or removing shims underthe base frame.

TM04

04890708

3Tighten the foundation bolt nuts against the base frame.Make sure the piping can be aligned to the pump flangeswithout putting strain on pipes or flanges.

3: Grouting

Grouting compensates for an uneven foundation, distributes theweight of the unit, dampens vibrations and prevents shifting.Use an approved, non-shrinking grout. If you have questions ordoubts about the grouting, please contact an expert on grouting.


1

Embed reinforcing steel bars into the foundation bymeans of 2K anchor adhesive glue.

The number of steel bars depends on the size of the baseframe, but it is advisable to distribute a minimum of20 bars evenly over the whole area of the base frame.The free end of the steel bar should be 2/3 the height ofthe base frame to ensure a proper grouting.

TM0404900708-TM0404910708

2Soak top of concrete foundation thoroughly, then removesurface water.

3 Ensure proper shuttering at both ends of the base frame.

TM0515623011

4

If necessary, check the levelling of the base frame againbefore grouting. Pour non-shrinking grout through theopenings of the base frame until the space underneaththe base frame has been filled completely.

Fill the formwork with grout up to the base frame toplevel.

Allow the grout to dry thoroughly before attaching pip ingto the pump (24 hours is sufficient time with approvedgrouting procedure).

When the grout has thoroughly hardened, check thefoundation bolt nuts, and tighten, if necessary.

Approximately two weeks af ter the grout has beenpoured, or when the grout has thoroughly dried, apply anoil-based paint to the exposed edges of the grout toprevent the grout from getting into contact with air andmoisture. TM

8.6 Pipework

8.6.1 Piping

When installing the pipes, make sure that the pump housing isnot stressed by the pipework.

The suction and discharge pipes must be of an adequate size,taking the pump inlet pressure into account.

Install the pipes so that air locks are avoided, especially on thesuction side of the pump.

Fig. 17 Pipelines

Fit isolating valves on either side of the pump to avoid having todrain the system if the pump needs to be cleaned or repaired.

Make sure the pipes are adequately supported as close to thepump as possible, both on the suction and the discharge side.The counter flanges should lie true against the pump flangeswithout being stressed as stress would cause damage to thepump.

Fig. 18 NB, NBG pump installation

8.6.2 Direct mounting in pipework

Pumps fitted with motors up to and including frame size 132 are

suitable for direct mounting in supported pipework.

Fig. 19 Direct mounting in pipework

This type of installation does not allow the use of expansionjoints .

8.6.3 Bypass

If there is any danger of the pump running against a closeddischarge valve, a minimum liquid flow through the pump shouldbe ensured by connecting a bypass or drain to the dischargepipe. The minimum flow rate must be at least 10 % of themaximum flow rate. The flow rate and head are stated on thepump nameplate.

8.7 Vibration dampening

8.7.1 Elimination of noise and vibrations

In order to achieve optimum operation and minimum noise andvibration, consider vibration dampening of the pump. Generally,always consider this for pumps with motors of 11 kW and up.For motors of 90 kW and up vibration dampening should beconsidered mandatory. Smaller motor sizes, however, may alsocause undesirable noise and vibration.

Noise and vibration are generated by the revolutions of the motorand pump and by the flow in pipes and fittings. The effect on theenvironment is subjective and depends on correct installation and

the state of the rest of the system.Elimination of noise and vibrations is best achieved by means ofa concrete foundation, vibration dampers and expansion joints.See fig. 18.

8.7.2 Vibration dampers

To prevent the transmission of vibrations to buildings, werecommend isolating the pump foundation from building parts bymeans of vibration dampers.

The selection of the right vibration damper requires the followingdata:

forces transmitted through the damper

motor speed, taking speed control, if any, into consideration

required dampening in % (suggested value is 70 %).

The selection of vibration damper differs from installation toinstallation. In certain cases, a wrong damper may increase thevibration level. Vibration dampers should therefore be sized bythe supplier of the vibration dampers.

If you install the pump on a foundation with vibration dampers,always fit expansion joints on the pump flanges. This is importantto prevent the pump from "hanging" in the flanges.

8.8 Expansion joints

Expansion joints provide these advantages:

absorption of thermal expansion and contraction of pipeworkcaused by variations in liquid temperature

reduction of mechanical influences in connection withpressure surges in the pipework

isolation of structure-borne noise in the pipework (only rubberbellows expansion joints).

The expansion joints should be fitted at a minimum distance of1 to 1 1/2 pipe diameters (DN) away from the pump on thesuction and the discharge side. This prevents turbulence in the

joints , thus ensuring optimum suction conditions and minimumpressure loss on the discharge side. At flow velocities > 5 m/s, werecommend fitting larger expansion joints matching the pipework.

Figures 20 and 21 show examples of rubber bellows expansionjoints with or without l imit ing rods.

Fig. 20 Rubber bellows expansion joint with limiting rods

Fig. 21 Rubber bellows expansion joint without limiting rods

Expansion joints with limiting rods can be used to reduce theeffects of the expansion/contraction forces on the pipework.We always recommend expansion joints with limiting rods forflanges larger than DN 100.

Anchor the pipes in such a way that they do not st ress theexpansion joints and the pump. Follow the suppliers instructionsand pass them on to advisers or pipe installers.

Figure 22 shows an example of a metal bellows expansion jointwith limiting rods.

Fig. 22 Metal bellows expansion joint with limiting rods

Due to the risk of rupture of the rubber bellows, metal bellowsexpansion joints may be preferred at temperatures above+100 C combined with high pressure.

8.9 Measuring instruments8.9.1 Pressure gauge and mano-vacuum gauge

To ensure continuous monitoring of the operation, we recommendinstalling a pressure gauge (on the discharge side) and a mano-vacuum gauge (on the suction side). The pressure gauge tapsshould only be opened for test purposes. The measuring range ofthe gauges should be 20 % above the maximum pump dischargepressure.

When measuring with pressure gauges on the pump flanges, itshould be noted that a pressure gauge does not register dynamicpressure (velocity pressure). On all NB and NBG pumps, thediameters of the suction and discharge flanges are differentwhich results in different flow velocities at the two flanges.Consequently, the pressure gauge on the discharge flange willnot show the pressure stated in the technical documentation, buta value which may be up to 1.5 bar (approx. 15 metres) lower.

8.9.2 Ammeter

To check the motor load, we recommend connecting an ammeter.

10. Electrical connectionThe electrical connection must be carried out by a qualifiedelectrician in accordance with local regulations.

The operating voltage and frequency are stated on thenameplate. Make sure that the motor is suitable for the powersupply of the installation site.

The electrical connection should be carried out as shown in thewiring diagram inside the terminal box cover.

10.1 Motor protection

Three-phase motors must be connected to a motor-protectivecircuit breaker.

All three-phase Grundfos MG and MMG motors of 3 kW and upincorporate a thermistor. See the instructions in the motorterminal box.

Carry out the electrical connection as shown in the wiringdiagram on the back side of the terminal box cover.

10.2 Frequency converter operationAll three-phase motors can be connected to a frequencyconverter.

Frequency converter operation will often expose the motorinsulation system to a heavier load and cause the motor to bemore noisy than usual due to eddy currents caused by voltagepeaks.

A large motor dr iven via a frequency converter will be loaded bybearing currents.

Check these operating conditions if the pump is driven via afrequency converter:

11.3 Priming

Closed systems or open systems where the liquid level isabove the pump inlet

1. Close the discharge isolating valve and slowly open theisolating valve in the suction pipe. Both the pump and thesuction pipe should be completely filled with liquid.

2. Slacken the priming plug (M) in order to vent the pump.Once liquid runs out, tighten the priming plug.

Suction operation with non-return valve

The suction pipe and the pump must be filled with liquid andvented before the pump is started.

1. Close the discharge isolating valve and slowly open theisolating valve in the suction pipe.

2. Remove the priming plug (M).

3. Pour liquid through the hole until the suction pipe and thepump are completely filled with liquid.

4. Fit the priming plug (M).

The suction pipe may be filled and vented via the priming plug.See fig. 24. Alternatively a priming device with funnel can beinstalled before the pump.

Open systems where the liquid level is below the pump inlet

1. If an isolating valve is fitted on the suction side of the pump,the valve must be fully open.

2. Close the discharge isolating valve and tighten the primingand drain plugs.

3. Connect a manual venting pump instead of a priming device(funnel).

4. A slide valve should be installed between the venting pump

and the centrifugal pump in order to protect the venting pumpagainst excessive pressure.

5. Once the slide valve at the manual venting pump has beenopened, vent the suction pipe using short, rapid pump strokesuntil the liquid runs out on the discharge side.

6. Close the valve at the venting pump.

Fig. 24 Drain and priming plug

11.4 Checking the direction of rotation

The correct direction of rotation is shown by arrows on the pumphousing. Seen from the pump end, the direction of rotation mustbe counter-clockwise. See fig. 24.

11.5 Start-up

Before starting the pump, completely open the isolating valve onthe suction side of the pump and leave the isolating valve on thedischarge side almost closed.

Start the pump.

Vent the pump during start-up by loosening the air vent screw inthe pump head/cover until a steady stream of liquid runs out ofthe vent hole.

When the pipework has been filled with liquid, slowly open theisolating valve on the discharge side until it is completely open.

Check the overload by measuring the motor current consumptionand comparing the value with the nominal current stated on themotor nameplate. In case of overload, throttle the valve on thedischarge side until the motor is no longer overloaded.

It is advisable always to measure the motor current consumptionduring start-up.

11.6 Shaft seal run-in period

The seal faces are lubricated by the pumped liquid, meaning thatthere may be a certain amount of leakage from the shaft seal.

When the pump is started for the first time, or when a new shaftseal is installed, a certain run-in period is required before theleakage is reduced to an acceptable level. The time required forthis depends on the operating conditions, i.e. every time theoperating conditions change, a new run-in period will be started.

Under normal conditions, the leaking liquid will evaporate. As aresult, no leakage will be detected.

Liquids such as kerosene will not evaporate, and drops will bevisible, but this is not a shaft seal failure.

11.7 Start/stop

11.8 Reference readings of monitoring equipment

We recommend taking initial readings of these parameters:

inlet and outlet pressure (use pressure gauges).

The readings can be used as reference in case of abnormaloperation.

12. Maintenance

12.1 Pump

The pump is maintenance-free.

12.2 Mechanical shaft seals

Mechanical shaft seals are maintenance-free, working almostwithout any leakages. If any considerable and increasingseepage occurs, the mechanical shaft seal should be checkedimmediately. If the sliding surfaces are damaged, the entire shaftseal should be replaced. Mechanical shaft seals should betreated with the greatest care.

12.3 Motor

Check the motor at regular intervals. It is important to keep themotor clean in order to ensure adequate ventilation. If the pumpis installed in a dusty environment, it must he cleaned andchecked regularly.

12.4 Lubrication

Motor bearingsMotors up to and including frame size 132 have maintenance-free, greased-for-life bearings.

Motors larger than frame size 132 should be greased accordingto the indications on the motor nameplate. Grease spills from themotor may occur.

Grease specifications: See section 12.4.1 Bearing grease.

12.4.1 Bearing grease

Lithium-based grease according to the following specificationsmust be used:

NLGI class 2 or 3

viscosity of basic oil: 70 to 150 cSt at +40 C

temperature range: -30 C to +140 C during continuous

operation.

13. Periods of inactivity and frost protectionPumps which are not being used during periods of frost should bedrained to avoid damage.

Drain the pump by removing the drain plug (E). See fig. 24.

Do not tighten the priming plug or replace the drain plug until thepump is to be used again.

If the pump is to be drained prior to a long period of inactivity,inject a few drops of silicone oil on the shaft at the bearingbracket. This will prevent the shaft seal faces from seizing up.

14. Service

If Grundfos is requested to service such a pump, Grundfos mustbe contacted with details about the pumped liquid, etc. before thepump is returned for service. Otherwise Grundfos can refuse toaccept the pump for service.

Possible costs of returning the pump are paid by the customer.
