Wilo-Flumen EXCEL-TRE 50-90

The Wilo‑Flumen EXCEL‑TRE 50‑90 is a larger‑capacity recirculation pump from Wilo’s Flumen EXCEL series, designed for wastewater treatment plants handling higher flow volumes. Like the 20‑40 model, it transports sewage between nitrification and denitrification tanks, but it is optimized for bigger installations requiring robust, continuous operation.

Description

The Wilo‑Flumen EXCEL‑TRE 50‑90 is a high‑capacity recirculation pump engineered for wastewater treatment plants, delivering reliable sewage transport between nitrification and denitrification tanks. Its non‑clog propeller design and stainless steel investment‑cast construction ensure durability and long service life, even under heavy‑duty operating conditions. Equipped with an IE3 energy‑efficient motor and frequency converter compatibility, the EXCEL‑TRE 50‑90 enables speed‑controlled, load‑sensitive operation that reduces energy costs in large installations. Flexible installation options, including lowering devices and screwless coupling, simplify handling and maintenance, while its adaptability to different pipe diameters and flow rates allows seamless integration into existing systems. Built for continuous duty, the EXCEL‑TRE 50‑90 provides dependable performance for municipal and industrial wastewater applications.
