Wilo-Flumen EXCEL-TRE 20-40

The Wilo‑Flumen EXCEL‑TRE 20‑40 is a high‑efficiency recirculation pump from Wilo’s Flumen EXCEL series, specifically engineered for wastewater treatment plants. It is designed to transport sewage between nitrification and denitrification tanks, ensuring reliable flow with minimal clogging and optimized energy use.

Description

The Wilo-Flumen EXCEL is the operationally reliable solution for draining CSO tanks and pump sumps. It impresses with high-speed submersible mixers that are made of high quality stainless steel and installed close to the ground. They constantly generate sufficient turbulence and therefore reliably prevent solids from settling. This also minimises cleaning work when draining CSO tanks and pump sumps. Even during periods of high rainfall and longer running times, the Wilo-Flumen EXCEL has a low clogging rate and is extremely reliable in operation. The new precision-cast stainless steel propellers prevent almost all cavitation, so that low-wearing operation is guaranteed at all times.

Non‑clog propeller design: Flow housing reduces blockages for continuous sewage transport.
Durable stainless steel propellers: Investment‑cast for long service life and reliability.
Energy‑efficient IE3 motor: Optimized hydraulics lower operating costs.
Frequency converter compatibility: Enables speed‑controlled, load‑sensitive operation.
Flexible installation: Lowering devices and screwless coupling allow easy setup and removal, even in filled basins.
Adaptability: Configurable for different pipe diameters and flow rates.
Continuous duty design: Built for uninterrupted operation in wastewater treatment plants.

Special applications

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
Reduction of the energy and operating costs due to the standard use of IE3 motors for the best possible thrust coefficient
High flexibility thanks to the most diverse installation options and accessories
