www.motralec.com / service-commercial@motralec.com / 01.39.97.65.10Product releaseITT Flygt AB2006-03-23 Lasse Jansson1. IntroductionThe successful N-pump series grows in size. The first large N pumps are3231, 3306, 3312, 3356 and the 3400.2. Product aimThe N-pumps are designed to combine the best non-clogging characteristicswith excellent efficiency. The self-cleaning impeller offers a trouble-freeoperation with sustained high efficiency as the main sales argument.3. CompetitionSome of our competitors, like ABS, claim they have a similar solution in their‘contra-block technique’. In fact, the only similarity is that they have an openimpeller. They do not have the N-design shape of the leading edge nor therelief groove working together with the leading edge.4. Product programThe new N 3231, 3306, 3312, 3356 and 3400 do not completely cover the Cpumps’ QH-range. This varies from pump to pump. For example, the N3312has slightly higher performance, whereas the 3400 has reduced performancecompared to the C-pump.The NPSH is generally not as good as that of the C-pumps. The final NPSHtest was positive and the NPSH curves have been revised from those earlierdistributed.The efficiency of the N pumps is generally good, on a level equaling the Cpumps.5. Specific technical features The N-technique offers the most reliable performance for handling ofwastewater and sustained high efficiency, using a combination of a specialdesigned leading edge in combination with a relief groove.6004.3 The impellers are of cast iron with a hardened leading edge. The insert rings are of cast iron and replaceable. Trimming is achieved by shims between insert ring and pump housing.G:\W\Wm\Avdelningen\Lasse\Product release N 3231-3400\Product release\Product release N lj.doc

StrategiesThe N-pumps should be the first choice in wastewater applications or in otherapplications where the best clogging characteristics are required. The Npumps are also suitable as problem solvers. Compared to a C-pump, the Npump should be premium priced. For upgrading of an old Flygt pump stationwith C-pumps, the choices are rebuilding or replacing by a new N-pump.7. Main market segments/ApplicationsThe N-pump is applicable where contaminated water can be expected. Inwastewater applications this pump shall always be the first choice.8. ReferencesAn early prototype of the NT3306 has been running in Köping, Sweden formore than 15000 hours. It replaced a CT3306, operated on VFD, which wasclogging with rags. The pump station is collecting wastewater from otherstations and pumps the wastewater to a treatment plant. The customer wasvery pleased with the pump, which now has been overhauled and taken overby the customer.9. Sales promotionThese items are available: N-brochure part no. 89 59 88Poster N3356/765 part no. 89 58 74Photos in the photo archive (There are no exterior differences vs. a C-pump).10. Technical documentation 6004.3Dimensional drawings are identical to those for C-pumps. All have beenadjusted to apply for both pump types.Installation, care and maintenance is updated with the N-pumps.Parts lists are updated for the N-pump.Product data is not updated, but will be in the future.There is no workshop manual available. Most of the valuable informationcan be found either in ‘Installation, care and maintenance’ or the technicalbulletins of how to rebuild C-pumps.Technical bulletins for rebuilding have been issuedG:\W\Wm\Avdelningen\Lasse\Product release N 3231-3400\Product release\Product release N lj.doc

www.motralec.com / service-commercial@motralec.com / 01.39.97.65.10Cut energy bills. Cut service costs.They revolutionized the market for small and midrangewastewater pumps. And now they are going to do thesame for large pumps.N-pumps cut costs in two ways. First, they slash energybills, in some cases by up to 50 percent. Second, theyradically reduce the number of service call-outs.This is why –N-pumps are the market’s most efficient submersibles for pumping contaminated water.N-pumps maintain incredible efficiency month aftermonth because fibrous material cannot build up on theimpeller. We call it sustained efficiency.N-pumps have excellent non-clogging properties,practically eliminating the risk of blockages.Higher efficiency plus non-clogging performance maysound too good to be true. But after nearly 10 years,small and mid-range N-pumps continue towin market share. And the outlook is similar,if not better, for large N-pumps.2

www.motralec.com / service-commercial@motralec.com / 01.39.97.65.10How it worksThe secret behind the award-winning N-technique isthe combination of a swept-back leading edge and arelief groove in the volute.Cuts energy costs by up to 50 percentLarge savings can be made when pumping contaminated water. This is because N-pumps give you highefficiency, day after day, week after week – we call itsustained efficiency.Nothing to get hooked onThe leading edge on most impellers is axial. This is theideal shape for rags and other long stringy materialto wrap themselves around. To avoid this problem,we flattened and swept back the leading edges of theimpeller.Eliminates build-up and efficiency lossThe problem with conventional impellers is the gradualbuild-up of stringy material. Over time, the passage inthe impeller narrows, reducing the amount of waterit can pump. So, as the impeller gradually clogs up,efficiency drops. As you can see in the table below, theN-technique sustains efficiency at its original rated levelmonth after month.Relief grooveTo help really stubborn material pass through the impeller, we developed a ”relief groove”. As the impellerturns, rags are forced into this spiral-shaped groove.The combined action helps to tug material from theimpeller into the volute where it is free to be pumpedaway.Sustained efficiency with N-pumpsN-pump running continuouslyConventional pump running intermittentlyConventional pump running continuouslyThe two-stage action is designed to prevent rags and other fibrousmaterial from accumulating on the impeller.Stage one: the leading edge is swept back, so there’s nothing ragscan get caught on.The red line shows how efficiency decreases when a conventionalwastewater pump clogs during continuous operation.The green line illustrates how a conventional wastewater pumprunning intermittently also suffers from low efficiency due toclogging. Temporary efficiency gains may be achieved throughback-flushing.The blue line shows the sustained efficiency of the N-pump.Stage two: rags get fed into the relief groove as the impeller turns,pulling them from the impeller and forcing them into the volutewhere they get pumped away.3

www.motralec.com / service-commercial@motralec.com / 01.39.97.65.10A wide range of applicationsBy combining increased pumping capacity with theself-cleaning properties of the N-technique, Flygthave opened up new possibilities for cost-effectiveoperation in all kinds of applications:Wastewater pumpingRaw water pumpingCooling waterSludge handlingStorm water handlingIndustrial effluent handlingIrrigationProcess waterFlygt submersibles operate directly in the pumpedliquid. This means low construction costs because Flygtpumps don’t require a special housing or a superstructure. Operating submerged also means that ourpumps take up very little space, are quiet and do notneed extra cooling.Get it right from the start. Use FLYPS, our proprietarypump selection software, to specify the right pumpand SECAD to optimise pump station design.Flygt submersibles are smaller than non-submersiblepumps because motor and hydraulics are integratedin one compact unit. That’s why pump stations forsubmersibles are smaller and less complex to build.NP – For semi-permanentwet well installations: thepump is installed withtwin guide bars and adischarge connection.NS – This installationmakes the pump easy tomove around with eithera flange that connects toa discharge pipe or a hosecoupling.NT – A vertical, dry-pit orin-line installation withflange connections forsuction and dischargepiping.4NZ – A horizontal, dry-pitor in-line installation withflange connections forsuction and dischargepiping.

Acooling jacket is available for dry-installed pumps andother applications.International standards approvalsEach pump is tested and approved in accordance withnational and international standards including IEC34-1, HI plus CSA. The pumps are also available inexplosion-proof versions for use in hazardous locationsand are approved by the Factory Mutual and EuropeanNorm (FM and EN).MonitoringThermal sensors in the stator windings help preventoverheating and the lower bearing is monitored by ananalogue temperature sensor. The stator housing andthe junction box are equipped with leakage sensors.Long-life bearingsThe bearings in all Flygt pumps have been designed toprovide a service life of at least 100,000 hours.Deflection-resistant shaftIn a Flygt submersible, the shaft’soverhang is kept very short to reduceshaft deflection. This results in lowvibrations, long seal and bearing life,plus quiet operation.Demanding tolerancesAll pumps are factory-tested andgiven a performance guarantee.Tests are conducted according toISO 9906 grade 1 or 2, HI level A or B.6

www.motralec.com / service-commercial@motralec.com / 01.39.97.65.10Engineered for a longer lifeAt Flygt, we design and manufacture all seals andelectrical motors ourselves. It’s the best way to ensurethe level of reliability and performance our customersexpect.Class H qualityInside all N-pumps you’ll find a squirrel cage inductionmotor, made to Class H specifications. Stator windingsare trickle impregnated with resin and rated at 180 C(355 F), allowing up to 15 starts per hour.Long-life sealsSeal surfaces must be able to withstand friction underhigh pressure and poor lubrication for thousands ofhours. Only a few materials are able to cope with suchconditions without cracking, seizing up or sufferingunacceptable levels of wear.The maximum temperature rise in a Flygt pump islimited to a NEMA B rise of 80 C (176 F). This ensures a significant increase in the operational life of themotor windings.Better heat transferIn Flygt motors, heat losses are concentrated aroundthe stator which, since it is surrounded by water, iseasier to cool than the rotor. Heat transfer is also encouraged because the stator is heat-shrink fitted.That’s why we use, as standard, a tungsten carbideespecially designed for Flygt. It’s a material that provides excellent protection against both corrosion andwear. This in turn leads to longer service intervals andsafer operation.Mechanical face seals are normally cooled by thepumped media, but this isn’t always the case. Toavoid overheating of the outer seal when running dry(Flygt pumps are equipped with double seals), the sealcompartment has been designed to dissipate heatquickly and efficiently.7

When it’s time to retrievethe pump, you simply attach the line to Dock-Lock.As you lower the device into the sump, it’s guidedstraight to the shackle by the line.SaferDock-Lock increases safety because the lifting hookalways gets a firm grip on the pump’s lifting shackle.When it reaches the top of the pump, it docks with theshackle. This triggers a spring-loaded mechanism thatsnaps the lifting hook securely into place. The pumpcan now safely be winched up.9
