Wilo-Flumen EXCEL-RZPE 20-40

The Wilo‑Flumen EXCEL‑RZPE 20‑40 is a high‑efficiency recirculation pump designed for wastewater treatment plants, ensuring reliable sewage transport between nitrification and denitrification tanks with low clogging and energy‑saving performance. It is part of Wilo’s Flumen series, optimized for continuous operation with frequency converter control.

Category: Sewage Pumps

Description

The highly efficient series Wilo-Flumen EXCEL-RZPE ensure reliable and non-clogging continuous operation when pumping sewage from the nitrification basin back into the denitrification basin. Wilo recirculation pumps are ideally suited for speed-controlled operation with a frequency converter to support the energy-efficient and load-sensitive control of wastewater treatment plants.

Non‑clog propeller design: Flow housing minimizes blockages for reliable sewage transport.
High operational reliability: Stainless steel investment‑cast propellers ensure durability and long service life.
Energy‑efficient motor: Equipped with IE3 standard motor for reduced energy costs.
Frequency converter compatibility: Supports 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 volume flows.
Simple replacement: Designed to adapt to existing installations for quick upgrades.
