Mid-size Mixers

Flygt 4530 Mixers


Optimal Efficiency in a New Dimension

The newest addition to the Flygt range of innovative mixers and agitators, the Flygt 4530 incorporates a state-of-the-art propeller and proven drive unit for optimal efficiency in medium size treatment tanks. Typical applications are mixing in activated sludge processes, sludge holding tanks, and digesters.


Improved energy consumption

Our aim is to help you achieve operational efficiency in energy intensive treatment facilities. Getting the right design and size in your mixing application can make the difference for cost effective operations. The Flygt 4530 mixer is an excellent choice when the propeller diameter of a full-size low-speed mixer is too large, but there’s room for something larger than a compact mixer. Compared to a direct-drive compact mixer, for example, the energy savings with the Flygt 4530 can be over 50% for a similar duty. With the most advantageous size, you’ll also get a dynamic duo of innovative propeller geometry and proven drive unit that’s all the better for high efficiency and smaller carbon footprint. 


Reliability you can count on

Hundreds of thousands of mixer installations around the world are confirmation of the reliability and robustness of our solutions. Designed and built to the same consistent high standards, the Flygt 4530 ensures minimum maintenance and fewer unexpected process interruptions, which add up to lower overall life-cycle costs.


Simplicity in the exchange

Changing out an existing installation is simple with the Flygt 4530. The mid-size mixer can be easily installed on a wall-mounted single guide bar, just like a compact mixer. What’s more, rapid, straightforward installation helps to reduce expenditure on your staff time and your budget.


Innovative propeller design

Finding inspiration in the standard-setting Flygt low-speed mixer, the 4530 propeller takes hydraulic efficiency and clog-free performance to new levels. A thin-section design that incorporates generous backsweep and double curvature,the rigid propeller is built for the best in efficiency and dependability.


Patented propeller assembly

Mounting is simple and easy. The attachment of the propeller requires no special tools – the design itself ensures correct mounting so you can be certain of optimal performance. In addition, the propeller bending and torsional loads are not taken by bolts, but rather recessed faces in the hub, for the  assurance of reliability.


Standard guide bar installation                                            
The Flygt 4530 can replace mixers installed on single guide bar systems. There is no special floor mounted pedestal required on which to place the mixer. This makes it easier to exchange out a compact mixer for the Flygt 4530, and achieve up to 50% savings on energy consumption.
Robust and adjustable, Flygt installation equipment directs thrust exactly where it is required and can withstand the
weight and reaction forces exerted by the mixer throughout
its operating life.

Proven drive unit

The drive unit design is based on the Flygt low-speed mixer, with its class H insulation, trickle-impregnated stator and rugged gearbox. Proof of design for the utmost in dependability and non-stop operations is demonstrated in tens of thousands of drive installations worldwide.
