Wilo-Flumen OPTI-RZP 20-40

The Wilo‑Flumen OPTI‑RZP 20‑40 is part of Wilo’s Flumen OPTI series, designed as a recirculation pump for wastewater treatment plants. It is used to transport sewage between nitrification and denitrification tanks, ensuring reliable flow with optimized hydraulics and energy‑efficient operation.

Category: Sewage Pumps

Description

The highly efficient Wilo-Flumen OPTI-RZP series ensures reliable and non-clog 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 energy-efficient and load-sensitive control of wastewater treatment plants.

Non‑clog propeller design: Flow housing minimizes blockages for continuous sewage transport.
Durable stainless steel propellers: Investment‑cast for long service life and reliability.
Energy‑efficient IE3 motor: Optimized hydraulics reduce 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.

Recirculation between nitrification and denitrification in the biological wastewater treatment
Returning return activated sludge to the activated sludge tank or for sludge treatment
Water circulation for aquaculture (fish farming)
Special applications

Reliable continuous operation due to low clogging propellers and flow housing that is pump in non-clog design.
High operational reliability by using stainless steel investment-cast propellers
Reduction of energy costs thanks to high pump efficiency
Customer-specific configuration taking into account the different pipe diameters and volume flows
Simple adaptation to the system parameters through operation with a frequency converter
Easy installation and removal, even when the basins are filled due to lowering devices and screwless coupling
Simple replacement due to adaptation to existing installations
