Rising to the mixing challenge
    All mixing applications require varying degrees of both small-scale turbulence and bulk flow. With a good bulk flow, the contents of the
    entire tank are put into motion so that all parts are involved in the mixing. The strength of the bulk flow is, in turn, dependent on the
    total amount of installed thrust and layout.

    Unparalleled expertise, broad mixing solutions

    Xylem 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 determine the right technology, mixer size and layout for your requirements.

    Our comprehensive portfolio of mixers and agitators cover virtually every requirement. Hundreds of thousands of Flygt mixers and
    agitators are in service worldwide, delivering efficient mixing performance..

    Low-speed mixing
    When mixing and horizontal flow is essential for biological wastewater treatment processes, Flygt low-speed mixers deliver outstanding
    cost-effective performance for applications that involve gentle mixing of large fluid volumes.

    Engineered for more efficient bulk flow, lower energy consumption and positioning flexibility, these mixers offer highly efficient solutions
    for a wide range of mixing applications, such as:

    Activated sludge treatment
    – Conventional treatment
    – Oxidation ditch
    – Sequencing batch reactor
    Wastewater reservoirs
    Ice prevention
    Oxygenization in lakes and harbors

    For decades, Xylem has been at the cutting edge of research and development to improve mixer technology. Flygt low-speed mixers
    feature several components that contribute to reliable operation and reduced energy costs.

    Energy-saving propeller
    Our unique propeller design maximizes the amount of thrust delivered while minimizing energy consumption.
    Engineered for hydraulic excellence with high-strength materials, our signature banana blade large-diameter propellers with backswept
    self-cleaning design provide non-clogging performance that lasts and lasts.

    Dependable Class H motor
    Our squirrel-cage induction motor is carefully manufactured at our own premises for durability and dependability. Stator windings are
    trickle impregnated in resin and rated at Class H 180°C (355°F) to provide excellent resistance to overheating and exceptionally
    long service life.

    Reliable shaft seals
    A vital component for reliable operation, Flygt mechanical shaft seals feature a unique design with an intermediate barrier fluid.
    Made of corrosionresistant tungsten carbide (WCCR), our specially manufactured seals provide exceptional mechanical strength
    and superior sliding properties. This results in significantly less wear between the seal surfaces. It also reduces the risk of leakage
    and prolongs seal service life.


    Cable entry
    Compressible bushing and strain relief on
    the cable prevent leakage into the motor.

    High-performance, squirrel-cage induction
    class H-motor provides thermal overload protection and extra long service life.

    Protective coating
    Durable, high-strength top coating protects
    cast-iron parts against impact, chemicals
    and corrosion.

    Thermal sensors embedded in the stator
    windings prevent overheating. Leakage sensors are available as options.

    Inner shaft seals
    Shaft seals between stator and gear box,
    and between gear box and seal housing.

    Thin-sectioned, double curved blades
    with a unique design for maximum efficiency
    and clog-free operation.

    Seal housing
    Seal housing containing barrier fluid, which
    lubricates and cools the seal and thereby
    prolongs service life.

    Outer shaft seal
    Mechanical shaft seal between surrounding
    liquid and seal housing has mechanical
    locking device to secure the seal position.
    This makes the seal reliable as well as
    easy to assemble and disassemble.

    Gear box
    Designed for years of trouble-free operation.

    The Flygt 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 tank
    To help withstand fatigue from strongly fluctuating forces within the tank,
    Flygt low-speed mixers are installed along rigid guide bars at appropriate
    depths for optimal mixing efficiency. Used together with our lifting
    equipment, guide bar systems enable easy access for inspection
    and service.

    Safe, convenient lifting equipment
    Raising and lowering Flygt low-speed mixers with our lifting equipment is
    as easy and convenient as it is safe. The CE-approved lifting davit is mounted in a holder at its lower end which enables easy turning of
    the davit. To reduce investment cost, one davit can be used wfor several mixers.
