Flumen EXCEL-TRE 20 … 40
Mixer
The most effective solution for draining CSO tanks and pump sumps.
- Low cleaning work by avoiding deposits during basin draining thanks to installation close to the groundnd
- Low clogging rate and reliable operation thanks to optimised hydraulics
- Low-wearing, due to the use of stainless steel precision-cast propellers with the lowest cavitation tendency
- A wide range of possible uses in diverse applications, even at high-interval running times

A reference from Switzerland
Modernising submersible mixers.
Why the Wilo-Flumen EXCEL?
Several rainwater basins or stacks are used for mixers in Switzerland. When designing the new Flumen EXCEL mixer series, special care was taken to ensure low-clogging mixing operation, as the system process requires a high level of operational reliability.
Numerical flow simulations – CFD simulations
Optimal system operation using modern design methods and system expertise.
Configuration
- The correct system-dependent design and installation of the mechanical technology is a basic requirement for efficient and operationally-reliable biological sewage treatment.
- During the design phase, we scrutinise our products for whether they can optimally fulfil your system requirements. For reliable system operation and minimum energy requirements. · Modern software-aided dimensioning tools and methods.
- CFD simulation (numerical flow simulation dimensioning method) for selecting the right technology for your system.
- Exact analysis of system-specific conditions enables possible weaknesses to be detected in good time and optimisation approaches to be developed.
FAQ
How long can the mixer be operated on draining?
As long as the minimum submersion of 30 centimetres is maintained, i.e. when the mixer is still covered with enough water. The small propeller diameter and installation close to the basin floor are beneficial in this regard.
How many mixers do I need in my stormwater retention tank?
Wilo’s team of specialists perform the dimensioning according to customer-specific requirements.
Which documents, facts, figures and data do we need fordimensioning?
We supply you with a checklist for all necessary information which you can use as a guide.
I am dissatisfied with the cleaning performance of my existing system. What can I do?
Contact Wilo. The full range of customer services is available to you daily across Germany from 7 am to 6 pm – including weekends and public holidays. You can contact the Wilo Service Centre by telephone on +49 231 4102 7900 or by e-mail to kundendienst@wilo.com
Can Wilo-Flumen EXCEL also be installed in existing systems?
Not only can Wilo-Flumen EXCEL and OPTI be installed in existing systems, but it is even possible to electrically integrate them with the switch cabinet currently in use This requires system-specific dimensioning by the experts at Wilo.
Which applications are Wilo-Flumen EXCEL and Wilo-Flumen OPTI suitable for?
- Stormwater retention tanks - Pump sump - Mixing and buffer basins - Small sludge activation plants - Special sludge tanks
Are high-efficiency mixer versions available?
All mixers in the Wilo-Flumen EXCEL series comply with EU-wide efficiency class IE3.

Construction
Propeller
2- or 3-bladed propeller made of solid material with a nominal propeller diameter of 200 mm to 400 mm. Clogging-free propeller geometry design made possible by backward-curved incoming flow edge.
Motor
Surface-cooled submersible motor in three-phase current design with permanently lubricated und large-size rolling bearings. The motor winding is equipped with temperature monitoring. The motor heat is given off directly to the surrounding fluid via the motor housing. The connection cable is designed for heavy mechanical loads, sealed water pressure-tight against the fluid and is sealed longitudinally watertight. The connection cable has bare cable ends and is 10 m (33 ft) long as standard.
The submersible motor meets the IE3 motor efficiency class (according to IEC 60034-30).
Seal
Large-volume sealing chamber with double shaft sealing. The sealing chamber is filled with white oil and absorbs the leakage from the seal on the fluid side. A corrosion- and wear-resistant mechanical seal is used on the fluid side. The seal on the motor side involves either a rotary shaft seal or a mechanical seal.
