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
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..
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
a wide range of mixing applications, such as:
For decades, Xylem has been at the cutting edge
of research and development to improve mixer

components that contribute to reliable operation
and reduced energy costs.
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
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
and superior sliding properties. This results
in significantly less wear between the seal surfaces.
It also reduces the risk of leakage

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

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.
