1 Flygt compact mixersRELIABLE VERSATILITY, HIGH EFFICIENCYC ompact mixing for any requirementINTRODUCTIONR ising to the mixing challengeAll mixing applications require vary-ing degrees of both small-scale tur-bulence and bulk flow. With a good bulk flow, the contents of the entire tank are set into motion involving in the mixing process. The strength of the bulk flow is, in turn, dependent on the total amount of installed thrust and layout. Unparalleled expertise, broad mixing solutionsFlygt pioneered the use of thrust as the main performance parameter for mixing. And every day, we put more than 50 years of R&D expertise and practical experience to work to deter-mine the right technology, mixer size and layout for your comprehensive portfolio of mixers and agitators cover virtually every requirement.

2 Hundreds of thou-sands of Flygt mixers and agitators are in service worldwide, delivering efficient mixing compact mixersEngineered for flexibility, versatility and lean installation, these space-sav-ing mixers offer highly efficient solu-tions for any tank shape and compact mixers easily blend highly contaminated fluids high-den-sity or high-viscosity liquids, and liq-uids with fibrous material. Few com-ponents, low capital investment and straightforward service routines make Flygt compact mixers the economi-cal choice for a broad range of mixing applications, like:n Activated sludge treatment such as conventional ASP or sequencing batch reactorn Sludge holding tanksn Equalization tanksn Pump station mixingn Grit chamber mixingn Chlorination basinsn Paper pulp chestsn Quenching tanksFlygt s wide array of reli-able, trouble-free mixing equipment includes.

Flygt compact mixer components contribute to RELIABLE opera-tion, reduced energy costs and efficient , robust direct-drive motorActive Seal for zero leakageThe Flygt Plug-in seal features the Active Seal system for zero leakage into the stator housing.

4 Laser-cut grooves on the inner seal faces, act as a micro-pump to force any liquid present on the drive-unit back to the buffer fluid side. The seal housing with barrier fluid helps lubricate and cool the seal, ensuring efficient heat transfer even when run-ning dry. Optional jet ring for increased mixing power kW02453167 Motor EFFICIENCY %4650 LSPM4650and up to 20% on energy compared to conventional induction housingThe large oil volume ensures smooth operation and long service intervals between refills. To make ser-vice easy, the oil plugs allow refill without removing the propeller. Optional LSPM motor for additional energy permanent magnet motorThe optional line-start permanent magnet (LSPM) motor for the Flygt 4650 compact mixer combines Our squirrel-cage induction motor is manufactured at our premises for durability and de-pendability.

5 Stator windings are trickle impregnated in resin and rated at Class H 180 C (355 F) for excellent resistance to overheat-ing and long service EFFICIENCY of a synchronous permanent magnet motor with the direct on-line starting of an induction motor. This saves on current-related costs, such as for cables and power supplies, Non-clogging, fiber-handling hydraulicsFlygt compact mixers feature an ef-ficient hydraulic design with few, easy-to-service components, which contributes to reli-able, trouble-free operation. Engineered to generate maxi-mum thrust with minimal use of energy, the propeller blades with their backswept design allow highly fibrous material to pass through. Wide-hub design deflects fibrous ring for higher efficiencyWith the optional jet ring, it is pos-sible to achieve an increase in mixer ef-ficiency by up to 15% in water and even higher in viscous media, while further reducing energy consumption.

Major parts in stainless entry Compressible bush-ing and strain relief on the cable prevent leakage into the motor, providing a RELIABLE seal with the Active Seal systemOffers increased sealing reliability and zero leakage into the motor, thereby reduc-ing the risk of bearing and stator with differ-ent blade angles, thin double-curved propel-ler optimizes mixing EFFICIENCY .

Leakage sen-sors are available as High-performance, squirrel-cage induction Class H motor provides thermal overload pro-tection and extra long service installationFlygt installation equipment is rigid enough to withstand the weight and reaction forces exerted by the mixer throughout its operating life. It is also robust and easy to work with. Guide bar systems for any tankTo help withstand fatigue from strongly fluctuating forces within the tank, Flygt compact mixers are usu-ally installed along rigid guide bars at appropriate depths for optimal mixing EFFICIENCY .
