Sometimes Mother Nature needs a handInnovative technology and nature hand in handApplication areasHuman existence and business prosperity in remote locations depend largely on the availability of clean water to people, livestockand crops. But in many parts of the world reliable power can be injust as short supply as the water. Grundfos SQFlex lends naturea helping hand by providing both water and the power neededto fuel the pump system. Areas that would previously have beenconsidered uninhabitable or not supportive of life suddenly become viable and attractive.Designed for continuous as well as intermittent operation, theSQFlex system is especially suitable for water supply in remotelocations such as:· v illages, schools, hospitals, single-family houses, etc.· f arms and ranches– watering of livestock– irrigation of crops and greenhousesBased on renewable energy sources such as solar and wind power, SQFlex combines state-of-the-art pump technology with sustainable, energy efficient solutions to provide a reliable watersupply to remote locations with little or no access to water andelectricity. The better the quality of the water, and the more reliable the water supply, the better the quality of life for everyone.·g ame parks and game farms– watering applications· c onservation areas– surface water pumping100% nature – just add waterWhether you are blessed with an abundance of sunshine or wind,or a bit of both, SQFlex solar panels or wind turbines adapt to thecharacteristic weather profile of any given area. A generator orbattery backup system can take over when the natural energysources are scarce, and accumulate energy when they are plentiful. With an SQFlex system, there is water whenever and wherever you need it. It is as simple as that!·p onds and lakes– floating pump installationsComplete system ready to goTell us where you are located, your water table depth and estimated water needs. By analysing location specific variables suchas average sunshine and wind speed, we can tailor the system soit matches your application and local conditions perfectly. SQFlexis a customised product delivered as a plug-and-go solution complete with SQF submersible pump, controller, energy source andsupport structure. The system is remarkably easy to install anduse under even the most difficult conditions.3

SQFlexStay flexible with SQFlexSQFlex pumpsThe complete SQFlex pump range consists of 11 different pump sizes: 5 helical rotor pumps formedium to high heads and low to medium flows, and 6 centrifugal pumps for shallow headsand high flows. It is available in two different stainless steel material variants: type AISI 304as standard and type AISI 316 for slightly aggressive water. The pump is fitted with a highefficiency motor for DC and AC voltage. This makes pump sizing and selection extremely easy.Solar systemsThe GF solar panels are designed especially for the SQFlex pump motor unit. A higher outputvoltage compared to standard 12V panels ensures optimum efficiency of the complete SQFlexpump system – with up to 20% flow increase per day in small systems. The solar panels incorporate bypass diodes, which minimise power loss in case the panels are covered by patches ofshadow, dirt, leaves or bird lettings. Wiring of the GF solar panels is easily done using the MCcable connectors.Wind systemsWhere wind speed prevails over sunshine hours, the SQFlex Wind is just as cost-effective andsustainable. SQFlex Wind is particularly suitable for open fields, valleys and landscapes wherethe wind blows constantly.Combi systemsThe SQFlex Combi takes maximum advantage of natural energy resources by providing a combination of solar and wind energy: solar panels for when the sun is shining; a wind turbine forwhen the wind is blowing. The added benefits of the SQFlex Combi are even greater reliabilityand water whenever it is needed.Backup systemsNatural energy rarely runs low, but if it ever does, both the SQFlex Solar and SQFlex Windsystems can temporarily use a petrol or diesel-driven generator or batteries. Intelligentcontrol units make changing between power supplies very easy.4

Control unitsThe SQFlex system is available with a user-friendly CIU 273 control unit that maintains two-waycommunication with the pump and monitors the operating conditions. Built-in diagnostics indicate faults and dry-running, display operating status power consumption and level switch input.Other alternatives are IO50 switch box and IO101 generator box for SQFlex Solar, and IO102breaker box for SQFlex Wind, which are controlled by a manual on/off switch.Grundfos Remote ManagementThe CIU 273 SQFlex is designed to work with the SQFlex pump and is acombined monitoring, control and communication unit for the SQFlex pump.CIU 273 enables monitoring the system operation anywhere in the worldthrough GSM network. Moreover, the CIU 273 enables connection ofa start/stop switch, level switch and pulsating water meter.CIU 273 also enables the use of Grundfos GOBattery backup systemBattery backup systems with a charge controller are typically used in applications where thepump is not running during most of the peak sun hours of the day, or where it is impossible orimpractical to store large volumes of water. Examples include remote homes or cabins, automatic livestock waterers, and very low-yielding wells. The SQFlex battery backup system enables SQFlex Solar to operate just like any traditional closed water supply system powered by themains supply, providing water pressure day and night.Youget it all· reliable water supplyLevel switch· cost-efficient pumpingSave energy as you save water. With a level switch insidethe storage tank connected to the CU200 or CIU 273control unit, the pump knows when the tank is fulland shuts itself off.· complete plug-and-pump system· Wide voltage rangeAC and DC voltage handling easy installation· virtually no maintenance· numerous expansion possibilities5

SQFlexQuality inside outSQFlex pumps have built-in protection features that protect the pumpitself and in many cases the well. Among these features are:· Protection against dry-running, overloading and overheating· Automatic restart when water returns to the well orwhen the motor temperature returns to the safety range· Continuous load condition and voltage monitoringPump casingStainless steel for long pump life.Helical rotor pump (3”)Based on original pumping principles, the helical rotor pump uses a few, simple componentsfor effective pumping – medium to high headand medium to low flow.Sand slingerTo ensure maximum protection of the motor and thus extended motor life, theSQFlex pumps are equipped with a composite sand slinger on the motor shaft asstandard. The sand slinger rotates with the shaft, thereby pushing sand away fromthe centre and out through three grooves in the pump sleeve. Another distinctivebenefit is that pump and motor can be replaced independently of one another, incase one of them wears out.6

BearingsPower transmissionPowerful carbon/ceramic bearing systemensures high reliability.The unique Grundfos micro frequency converterensures power transmission to the motor.MotorsAny voltageOne motor size are available for the SQFlex systemwith built-in unique features: 3600 rpm for helicaland centrifugal pumps, segmented stator andpermanent magnet rotor for high efficiency andstarting torque.A wide voltage range enables the motor to operate atany voltage between 30V - 300V DC or 90-240V AC,which makes installation and sizing especially easy.CommunicationTwo-way mains born communicationbetween control unit and pump eliminates the need for additional wires.Dry-running protectionSystem efficiencyThis unique feature shuts down the pumpif it detects water shortage. It protects thewell from being over-pumped and the motorfrom burning out. The pump restarts automatically when water returns to the well.Maximum Power Point Tracking (MPPT)means even and high system efficiencyregardless of power source.Centrifugal pump (4”)Technology based on 30 years’ experienceenables high flow in shallow water conditions.Stainless steel components give high wearresistance.7

Choose the win-win alternativeIndividual solutions to remote water supplyFocus on lifecycle costsSQFlex’s many possibilities and areas of application means thatit constitutes the perfect sustainable, reliable and cost-efficientalternative to irregular, cost-intensive water supply solutions inremote locations. It provides individual solutions to water problems where conventional water supply systems fail or simplycannot reach – and at hardly any cost. By opting for green technology, you can contribute to increased sustainability – for thebenefit of your business and nature in general.You cannot afford not to. The initial upfront investment in aSQFlex solution is comparable to conventional water supply systems. But this is where the comparison stops. The total cost ofowning a pump system over its entire life is about much morethan just the purchase price – it is the total sum of not only thecosts but also the benefits of having a business relationship withGrundfos.The lifecycle costs of an SQFlex system will be considerably lowerthan with other water supply systems, because you can save substantial sums on reduced energy and maintenance costs. Othermore intangible cost-reducing factors include correct systemsizing, high pump efficiency and performance, technical advice,service and reliable logistics.Turn harsh conditions into your advantageInstead of working against nature, you can work with it. Use thesun or the wind, or a combination of both, to create power foryour water supply system. For instance, in warm places there istraditionally more sun than wind, and with SQFlex Solar you cantake maximum advantage of the local weather conditions by relying on solar energy all the year round.Water, wherever, whateverYou can count on quick and efficient service from you localGrundfos dealer/installer in case your SQFlex system needs ageneral service check-up or a new spare part. Grundfos offers aclose-knit service network with own service organisation in morethan 40 countries combined with hundreds of Grundfos ServicePartners, installers and dealers worldwide. Efficient logistics ensure rapid delivery of spare parts, which are handled from one ofour strategically placed distribution hubs.Work smart, not hardWith an SQFlex system, the time-consuming and often dangerous work of climbing a traditional windmill structure to performregular maintenance on body, wings and gearbox will be history. So are the expensive insurance policies covering hazardouswork. SQFlex solar panels and wind turbines are virtually maintenance-free and much safer to handle.11
