DORTMUND, Germany - KSB Aktiengesellschaft, Germany has supplied 21 pumps to Emschergenossenschaft for use in the Emscher sewer, also known as Emscher canal, which is currently Europe’s largest wastewater project.

The pumps are employed as main pumps in two new pumping stations run by Emschergenossenschaft in Bottrop and Gelsenkirchen.

Specially modified, the pumps from the Sewatec range were delivered for this project.

The biggest pump sets each have a drive rating of 470 kW and handle up to 6480 cubic metres per hour.

A special technical feature of the pumps is their casing design. Unlike Sewatec’s standard casing, the casings for this variant were designed with tangential discharge nozzles by KSB engineers to achieve even better efficiencies.

The impellers were also optimised to ensure excellent efficiencies without compromising on the high level of operating reliability.

The efficiencies the pumps achieved on the test facility exceeded the values established via the CFD (computational fluid dynamics) simulation.

The pumping stations in Bottrop and Gelsenkirchen are used to lift the wastewater from the eastern Emscher valley to sewer sections located at a higher level.

From there the water flows to the wastewater treatment plants operated by Emschergenossenschaft.

Over a distance of 51 kilometres, the Emscher canal collects the wastewater produced by more than 1.8 million people and effluent discharged by industrial plants and commercial businesses in the area.

The canal transports the wastewater to the treatment plant in Bottrop and the Emschermündung wastewater treatment plant in Dinslaken.
