2 INTRODUCTION Eergy-efficiet mixig Advatages of Flygt low-speed mixers Risig to the mixig challege All mixig applicatios require varyig degrees of both small-scale turbulece ad bulk flow. With a good bulk flow, the cotets of the etire tak are put ito motio so that all parts are ivolved i the mixig. The stregth of the bulk flow is, i tur, depedet o the total amout of istalled thrust ad layout. Uparalleled expertise, broad mixig solutios ITT pioeered the use of thrust as the mai performace parameter for mixig. Ad every day, we put more tha 50 years of R&D expertise ad practical experiece to work to determie the right techology, mixer size ad layout for your requiremets. Low-speed mixig Whe mixig ad horizotal flow is essetial for biological wastewater treatmet processes, Flygt low-speed mixers deliver outstadig cost-effective performace for applicatios that ivolve getle mixig of large fluid volumes. 2 Outstadig reliability Strog bulk flow Extreme eergy efficiecy Easy to service Lea istallatio Highly versatile for most tak sizes Low total cost of owership Egieered for more efficiet bulk flow, lower eergy cosumptio ad positioig flexibility, these mixers offer highly efficiet solutios for a wide rage of mixig applicatios, such as: Our comprehesive portfolio of mixers ad agitators cover virtually every requiremet. Hudreds of thousads of Flygt mixers ad agitators are i service worldwide, deliverig efficiet mixig performace. Activated sludge treatmet Covetioal treatmet Oxidatio ditch Sequecig batch reactor Wastewater reservoirs Ice prevetio Oxygeizatio i lakes ad harbors Our comprehesive mixig portfolio ITT s wide array of reliable, trouble-free mixig equipmet icludes; Flygt low-speed mixers Flygt compact mixers Flygt top-etry agitators Flygt jet mixers Flygt hydroejectors

3 DESIGN Desiged for high reliability For decades, ITT has bee at the cuttig edge of research ad developmet to improve mixer techology. Flygt low-speed mixers feature several compoets that cotribute to reliable operatio ad reduced eergy costs. Eergy-savig propeller Our uique propeller desig maximizes the amout of thrust delivered while miimizig eergy cosumptio. Egieered for hydraulic excellece with high-stregth materials, our sigature baaa blade large-diameter propellers with backswept self-cleaig desig provide o-cloggig performace that lasts ad lasts. The Flygt baaa blade propeller creates maximum thrust usig miimal power. Depedable Class H motor Our squirrel-cage iductio motor is carefully maufactured at our ow premises for durability ad depedability. Stator widigs are trickle impregated i resi ad rated at Class H 180 C (355 F) to provide excellet resistace to overheatig ad exceptioally log service life. Reliable shaft seals A vital compoet for reliable operatio, Flygt mechaical shaft seals feature a uique desig with a itermediate barrier fluid. Made of corrosio-resistat tugste carbide (WCCR), our specially maufactured seals provide exceptioal mechaical stregth ad superior slidig properties. This results i sigificatly less wear betwee the seal surfaces. It also reduces the risk of leakage ad prologs seal service life. Stator widigs are rated at Class H for exceptioal resistace to overheatig. Uique mechaical shaft seal demostrates superior slidig properties ad exceptioal mechaical stregth. 3

5 DESIGN The best way to depedable, low-cost istallatio The Flygt istallatio equipmet is rigid eough to withstad the weight ad reactio forces exerted by the mixer throughout its operatig life. It is also robust ad easy to work with. Guide bar systems for ay tak To help withstad fatigue from strogly fluctuatig forces withi the tak, Flygt low-speed mixers are istalled alog rigid guide bars at appropriate depths for optimal mixig efficiecy. Used together with our liftig equipmet, guide bar systems eable easy access for ispectio ad service. Safe, coveiet liftig equipmet Raisig ad lowerig Flygt low-speed mixers with our liftig equipmet is as easy ad coveiet as it is safe. The CE-approved liftig davit is mouted i a holder at its lower ed which eables easy turig of the davit. To reduce ivestmet cost, oe davit ca be used wfor several mixers. The guide bar system makes mixers easily accessible. No costly modificatios to existig taks are required. 5
