Fresh, clean water is a valuable re-source. The extraction and properplanning for the supply are there-fore a constant challenge. Efficientmethods and the development ofnew sources, such as demineralised

seawater or aquifers (ground waterlines), secure the user supply. Thisrequires flexible systems which meetindividual requirements.

Water controlWater control/ground water drawdownsput a wide range of requirements onpumps and systems, for example, pump-ing off low water levels. Whether in water treatment plants or water reservoirs, with Wilo pumps, it is possible to realisepurposeful and efficient solutions.

RainwaterWater is becoming more and morescarce. Only a small portion (less than1 %) of all freshwater resources isavailable as surface water in lakes andrivers. This is alarming just from anecological point of view, and requires that this vital resource be handledresponsibly. Moreover, the shortagealso has economic consequences,of course, which can be seen from the continuous increase in the priceof water. Wilo offers innovative watersupply solutions with rainwater utilisation systems.

Ground and potable waterGround water is used in many different ways. After treating the raw wateraccording to the requirements ofpotable and process water, it is con-ducted to water reservoirs or thepotable water system. For this, Wilooffers pumps with a wide range of motor powers, delivery heads and volumeflows. In addition, our borehole pumpscan be installed horizontally as well as vertically in basins and tanks.

Water extraction.Solutions for every field of application.

Wells and sumpsWhen pumping ground water out ofdrilled wells, the installation depth andproductivity determine which pumpsare used. The wide spectrum of Wiloborehole pumps range from 4 to 24and are also matched to all common well diameters, guaranteeing optimalpumping operation.

Lakes and dams Among other things, barrages aredistinguished by the changing waterlevel of natural lakes, which generallyhave small water level fluctuations.Wilo offers you solutions at the bestpossible efficiency to minimise energycosts and with high-grade materialsfor long, maintenance-free pumpoperation.

Rivers and oceansRiver water and seawater require theuse of resistant materials due to con- taminants, sand content and salinity.Wilo meets these requirements byusing the most modern materials andadvanced technology. Materials, suchas Duplex or Ni-Al bronze and coatingssuch as Ceram withstand corrosionfrom aggressive or abrasive fluids andguarantee the longest service life.

Wilo-EMU borehole pumps EMU technologyWilo borehole pumps of the Wilo-EMU NK,K and KM series provide the optimalsolution for sophisticated tasks in water extraction and water control.These single- or multistage centrifugalpumps are used directly in the fluid.

In addition to the slender design, thesehigh-quality units convince with theirhigh efficiency. The exact trimmingof the impeller diameter allows thedesired flow capacity to be exactlydefined and, with this, cost-saving andenergy-efficient solutions for nearlyany application are possible. The se-lection criteria here are the best-pos-sible efficiency for minimising energycosts and the use of resistant materialsfor long and maintenance-free pumpoperation.

In order to guarantee the highest pos-sible operating reliability, every singleimpeller stage has a standard slidebearing. The extensive product rangegoes from 6" to 24" and beyond. Thesepumps are suspended vertically on the ascending pipe, but can also beinstalled horizontally in lakes, basinsand rivers and are ideally suited forlong-term operation.

Wilo-Sub borehole pumps made ofstainless steelThe Wilo-Sub TWI 4", 6", 8" and 10"product series include the new bore-hole pump range with a stainless steeldesign from Wilo. In addition to watersupply, this series made of stainlesssteel is suitable for many other appli-cations. Thanks to the extensive bear-ing pump program in the range of 4"and 6", they are always quickly avail-able.

Wilo-Sub TWI pumps can be installed vertically or horizontally, dependingon what's needed. Last but not least, the reduced weight ensures easy han-dling and installation. Thanks to thestable design, all units are very wear-resistant, even for high sand contentup to 50 mg/l. Long-lasting durabilityand high operating reliability are thenguaranteed.

In addition to quality and safety, thecost factor is also decisive: With opti-mised hydraulics and increased effi-ciency and the option that all pumpsof this series are suitable for frequencyconverters, they help lower the oper-ating costs. Additional advantages,such as the extensive range of acces-sories and a standardised hydraulicsdesign in AISI 304, round off the high-quality and versatile product portfolioof the Wilo-Sub TWI series.

The set-up is equivalent to an invertedborehole pump with the pump partand suction strainer in the lower areaand an overflow-proof motor above the hydraulics. Suctioning via a suctionstrainer and an integrated intake guide with an anti-vortex plate allows a verylow drawdown of the water level of just a few centimeters.

Wilo-EMU polder pumps are availablein cast iron or bronze/stainless steel.This wear-resistant version also allowsit to be used in contaminated or corro-sive fluids. The performance rangelies between 501200 m 3 /h volumeflow and delivery heads from 170 12 meters.

Wilo-EMU polder pumpsThe polder pump combines the tech-nical advantages of a s ubmersible-motor pump with the options for usinga conventional shaft pump. The pump was specially developed for use in water purification and irrigation plantsand for pumping out low water levels.

They are characterised by high effi-ciency, operating reliability and aremaintenance-free. The installation iseasy and low-cost, even in the case ofolder systems, for example, as a mod-ernisation and replacement for obso-lete shaft pump stations, because thepumps are flange-mounted directly to the existing pipe.

Wilo-EMU KM 1300 borehole pumpwith CoolAct motor technology Internal active cooling For optimised durability High degree of efficiency

The new 10", 12" and 16" submersiblemotor series is available in 2- and 4-pole versions, 50/60 Hz with voltagesfrom 200 1000V and up to 6600 Vfor 16". They can be set up verticallyand sometimes even horizontally.

Innovative motor technologyThe newly designed CoolAct motorseries with internal active cooling anda performance range from 75 kW to630 kW (50 Hz) allows the maximumoutput power for a minimum motordiameter.

Compared to conventional motors, the units with CoolAct technologyprovide up to 25% more power anda higher power density for the samepackage lengths. This is made possibleby internal active closed-circuit cool-ing. Thanks to a constantly driven im-peller on the motor shaft, the coolingfluid is conducted directly through the bearing and winding. This way, the heat given off by the motor canbe optimally absorbed and be passedon to the circulating fluid via the outermotor jacket in a defined way.The small installation diameter alsoreduces the investment and construction costs of wells and water pumpingsystems. The optimal efficiency alsoensures lower operating costs.

CoatingsThe unique Ceram coating from Wilocan be used for borehole pumps on theinner and outer surfaces of pumps andpump components which are exposed to aggressive fluids. This solvent-free2-component coating in the Ceram C0and C1 versions can be used for hy-draulics larger than 8" and can be ap-plied later on all pump components which are in stock.Thanks to the high wet adhesion of15N/mm2, high abrasive strength isguaranteed.

NEW Ceram CTThis coating with KTW approval (KTW =official German recommendationconcerning the levels of polymers inpotable water) was specially designedfor borehole technology to additionallyincrease the efficiency. With a thicknessof about 200 micrometers, Ceram CT isonly applied to the impeller blades andinner contour, as well as inside thestage housing.

The efficiency can be increased by these coatings by about 2% of the total efficiency. The investment pay-back period can sometimes be as less than 40 days.

Special materialsThe constantly increasing requirementsdue to corrosive or abrasive componentsin the fluid require innovative solutions.Therefore, high-grade materials, suchas duplex and Ni-Al bronze or other various stainless steels are used, forexample.

Duplex/super-duplex steel lThese non-rusting duplex steels arerecommended in acidic fluids, seawater and brackish water, as well as insaline and mixed salt solutions.

Ni-Al bronzeCompared to G-CuSn10, Ni-Al bronzehas a lower density, but has higherstrength and fracture strain. Used inseawater, the material shows verygood corrosion resistance thanks to the combination of the alloy elementCu and the resistance of the oxidic Alprotective film.

Rainwater utilisationIncreasing water costs are also notice-able in public and municipal facilities.It's about time an innovative approach to water supply be taken: with rainwater utilisation systems from Wilo. A large portion of the incidental waterrequirement can be very easily coveredby rainwater utilisation. This is goodfor the environment and the budget.

Fire protection and fire extinguishing technologyDifferent building situations, combined with different regional regulations,require specific solutions. Fire extin-guishing systems can be individuallyassembled with high-quality Wilocomponents. Profit from our know-how and our highly efficient pump technology.

Sprinkling and irrigationTo lessen the disadvantage of insuffi-cient water supplies or to make use of the advantage of nearby reservoirs ispossible with modern pump technol-ogy from Wilo. Our borehole pumps areused for sprinkling and irrigation, likein agriculture, for commercial purposesor for city/public parks.

Water transport.Solutions for every field of application.

Raw water distribution A reliable water supply is the basis for the functioning of social structures.There are high demands on pumps andsystems in places to where the vitalresource water has to be transportedand where it is needed and consumed.Wilo has a lot of experience and effi-cient technology to guarantee that water is reliably distributed over longdistances at the required pressure.

Pressure boosting systemsSupplying water via pressure boostingsystems has long since been one of thecore competences of Wilo. Our multi-faceted systems can be adapted toa wide range of requirements so thateven complex water circuits with amultitude of consumers can be opti-mally supplied at any time: even at stag-gering heights. This way, the largestpressure shroud pumps manage deliv-ery heads of up to 600 meters.

Pressure boostingEfficient water supplies increasinglyrequire the utilisation of intelligentinstallations made up of optimallymatched components.Systems likeWilo pressure boosting systems, themain component of which is the newWilo-Helix high-pressure multistagecentrifugal pump. The pumps of theHelix series are used in public andmunicipal facilities and impressivelyshow what one can do under highpressure.

Wilo norm pumpsThe norm pump series is suitable forclean to slightly contaminated water in circulation, transfer andpressure-boosting applications. Here, the low-pressure centrifugal pumpsachieve delivery heads of up to 150 mand volume flows of up to 3000 m3 /h.Generously dimensioned roller bear-ings as well as high-quality sealingsystems, such as the Burgmannmechanical seal with tapered gasketchamber, guarantee a high degree ofoperating reliability. To reduce maintenance-related downtimes, all pumpscan be equipped with a spacer cou-pling. With this, there is direct access to the hydraulics without having todismantle the pipe or the drive.The standardisation of the main com-ponents guarantees better exchange-ability. In addition, all pumps from the Wilo norm pump series havea hydraulically balanced impeller.

Wilo split case pumpsFor maximum capacity. The main char-acteristic of these single- or dual-stagelow-pressure centrifugal pumps withaxially divided housings are low NPSH values. Thanks to the double suctioning, the impeller is hydraulically balanced,so that the axial thrust is minimisedand the pump reliability is considerablyincreased. All standard pumps are gen-erally equipped with impellers and stationary wear rings made of bronze.

To make maintenance easier, the upperhousing part can be very easily dis-mantled. This way, one gets directaccess to all rotating parts withouthaving to dismantle the pressure orsuction lines or the drive. To position the components during assembly,all standard pumps come standard-equipped with stationary wear rings.The minimised shaft distortion due to intermediate bearings means fewer vibrations and, to avoid premature wear in the mechanical seal, all pumpscome equipped with a rinsing device.Wear-resistant 4- and 6-pole motors, the shaft sealing with mechanical sealor stuffing box packing, as well as high-quality materials, guarantee maximumoperating reliability. Wilo-SCPs areavailable as a special version with a volume flow of up to 17,000 m3 /h andmotors with special voltages, such as6000 V.

Wilo pressure shroud pumpsPressure shroud pumps are used forpressure boosting in supply and circu-lation systems and provide sufficientpressure in high-rises, areas built athigher altitudes and plants. They can beinstalled vertically, and even horizontally up to a certain number of stages.In the case of vertical installation, thepump system is to be accommodatedon as small an area as possible. In thecase of a horizontal installation position, the entire pipe installation liesin one plane, because Wilo pressureshroud pumps are flange-mounteddirectly in the mains supply line orare connected to a bypass pipe. Wilopumps can be produced according to the specifications of the local condi- tions. When installed directly in thepipe, the pump can also be equipped with a annular suction valve, makingfree flow possible even when thepump is switched off.

Wilo-Economy/Comfort/Comfort- Vario pressure boosting systemsDepending on demand, Wilo offerspressure boosting systems with differ-ent performance values. They each aremade up of several single pumps con-nected in parallel and a matching electronic control unit the CC controller.Intelligent programming guaranteesrolling and intermittent operation ofmultipump systems according to theiractual power requirement. The operation of the CC controller is possible with or without a frequency converterfor controlling the respective base-load pump. In addition, it has extensiveand flexible remote communicationoptions. This makes easy remote control and system diagnostics from aGSM modem and cell phone possibleon up to four receivers. All Wilo pres-sure boosting systems have one thingin common: They are highly compact,and very space-efficient. That makesit much easier to carry out installationand any servicing work which maybe required. Wilo supplies all pressureboosting systems completely pre-assembled and ready for connection.

Wilo-Multivert MVISWith the Wilo-Multivert MVIS, Wilo is the first and only provider worldwide who has been able to utilise glandless technology for water supply and pres-sure boosting in large buildings.The main advantage compared to the formerly usual glanded pumps: the extremely quiet operating noise.For the Wilo-Multivert MVIS thequietest pump in its class this is just40 dB (A). This is about the same as the gentle rustling of the leaves on a tree.

Easy installation and quick maintenanceHelix high-pressure multistage centrifugal pumps can be installed in twodifferent positions, depending on theinstallation situation: frontal or rotatedby 90 (single connection or integra- tion in a pressure boosting system)Rotatable and adjustable loose flangescan be set to any counter flange position.

User-friendly control, thanks to "redbutton" technology makes it possible to control all functions with a singlebutton. A significant advantage of the Helix high-pressure multistagecentrifugal pump is the X-seal cartridge system: It is easy to access, thus ensuring an extreme reductionin the time required for maintenance work. The cover is easy to dismantle.If the cartridge system needs to bereplaced, then the replacement timeis only around 1520 min even for the largest pumps in the series and thus only a third of the time normallyrequired. By removing the spacercoupling ("spacer" function) for pumpmodels that have motors starting from5.5 kW, space can be made in a simplefashion this makes it possible toreplace the mechanical seal withouthaving to remove the heavy motor.The exchange becomes easier this way.

Low energy consumption. Advanced, conscientious cost planningis the focus of the newly constructedWilo-Helix high-pressure multistagecentrifugal pumps. They are used in the water supply and ensure constantpressure all the way up to the largestheads. Thanks to the interaction ofnew pump design, high-efficiencyhydraulics and energy-saving EFF1motors, the pumps of the Helix seriesconsume about 15 % less energy thanstandard pumps with conventionalmotors and hydraulics systems.

Low life cycle costsThanks to their low energy consumption, Helix high-pressure multistagecentrifugal pumps function, on theone hand, very economically. On theother hand, extraneous operatingcosts, which include installation, maintenance and repair costs, are excep- tionally low with the Helix series.The reason for this is to be found ininnovative design solutions and theuse of high-quality, low-wear materi-als. Helix high-pressure multistagecentrifugal pumps are also less prone to malfunctions and have a long serv-ice life, which means that the costbalance over the entire life cycle of the equipment, taking into accountall of the relevant factors includingsuch things as purchasing and dis-posal costs is significantly better.

Sprinkling and irrigationWith the Wilo-Sub TWI series, Wilooffers high-performance pumps forcommercial and municipal water sup-plies. These high-quality pumps madeof stainless steel are especially suitablefor applications involving pumping water out of boreholes or rainwaterstorage for the purpose of sprinklingand irrigation. The entire Wilo-Subrange is convincing with its easy in-stallation, maintenance and operation.

Rainwater utilisation.The sensible utilisation of rainwater with specially designed systems isinexpensive and is good for the envi-ronment. A rainwater utilisation system combines modern technology with ecological awareness. Thanks tointelligent systems, rainwater is beingutilised reliably and with no hygienicconcerns for sprinkling/irrigation, sub-ordinate cleaning purposes and otherapplications in the non-potable waterarea. After all: Rainwater is excellentlysuited for irrigation and cleaning, sinceit is especially lime-free and is there-fore better for absorbing mineral saltsand active detergents.

The Wilo-RainSystem AF 400 is aready-to-connect rainwater utilisationsystem with a double pump, includinga booster pump. A feeding pump from the Wilo portfolio is for supplying rainwater fully automatically from rainwater storage or tanks. The system hasa large hybrid tank with a 400-litercapacity. When there is little rainfall, this is supplied by means of automatic,needs-based replenishment withpotable water from the mains system.This way, there is always a sufficient water supply. The fully electronic control unit controls the operation of theentire system and ensures maximumoperating reliability. The system sepa-ration guarantees the complete sepa-ration of the rainwater installationfrom the potable water supply inaccordance with EN 1717.

For a much higher demand, such as fire water, sprinkling, process water provi-sion or for rainwater retention, smallpressure boosting systems in combi-nation with Wilo system accessories(like an atmospherically vented tank)are still suitable. Using with multistagehigh-pressure centrifugal pumps guar-antee maximum operating reliability with up to 6 individual pumps, as wellas high efficiency, and offers two adjustable pressure levels for various ap-plications.

Pumps for sprinkler systemsSprinkler systems are automatic fireextinguishing systems which are usedfor preventive fire protection in specialbuildings, such as high-rises, assemblyhalls, underground garages, etc. Wilooffers an extensive product range forsprinkler pumps. These boreholepumps with VdS approval are used topump fire water in sprinkler systems.They are usually installed horizontallyin supply basins. Vertical use in wells orsumps, as well as dry well installation(with pressure shroud) are also possi-ble.

Wilo-EMU D 500The VdS-certified borehole pump,Wilo-EMU D 500, with CoolAct motor technology was developed to expand the portfolio in the area of sprinklerpumps with regard to high volumeflows and large heads. Large sprinklersystems, which up till now had to beequipped with several units, can nowbe operated with just one pump. Sinceno external cooling jacket is necessary, the pump can be installed taking upeven less space.

Fire protection and fire extinguishing technologyFire protection and fire extinguishingsystems are only used in the event ofa fire. Systems can be individually as-sembled with high-quality Wilo com-ponents. For example, with a fullyautomatic water-supply unit in a heavy-duty system made up of a high-pres-sure multistage centrifugal pump andstandardised motors. When planning,constructing and commissioning fireextinguishing systems for connection to a potable water installation, it mustbe made sure that the systems areseparated by a s o-called atmospheri-cally vented tank.
