Designed for high reliability

Flygt low-speed mixers feature several components that contribute to reliable operation and reduced energy costs, including energy-saving propellers, dependable class H motors, and reliable shaft seals.

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

Xylem's Flygt squirrel-cage induction motor is carefully manufactured for durability and dependability. Stator windings are trickle impregnated in resin and rated at Class H 180 degrees C (355 degrees F) to provide excellent resistance to overheating and exceptionally long service life.

A vital component for reliable operation, Flygt mechanical shaft seals feature a unique design with an intermediate barrier fluid. Made of corrosion-resistant tungsten carbide (WCCR), Flygt 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.

Dependable and easy to install

Flygt equipment is rigid enough to withstand the weight and reaction forces exerted by the mixer throughout its operating life. It's not only robust, but easy to use.

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

Raising and lowering Flygt low-speed mixers with Flygt 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 for several mixers.

Installation of Flygt low-speed mixers are ideal for use in:

  • Activated sludge treatment - conventional treatment, oxidation ditch, sequencing batch reactor
  • Water reservoirs
  • Ice prevention
  • Oxygenation in lakes and harbors
  • Biogas generation tanks
