Submersible pumps in two-story setup
Sulzer delivers pumps for the largest water construction project in Europe
As part of the reconstruction of the Emscher river and its tributaries, a multistory underground facility is being built in Gelsenkirchen at the river Hüller Bach. This project comprises three reservoirs, two rainwater treatment plants and three pumping stations. The excavation has a diameter of around 33 meters. Numerous and sometimes very large pumps are needed because of the large quantities of water. Sulzer delivered the submersible pumps for the plant that is expected to be operational in 2020.
The challenge
As soon as the pumps are in operation, the underground parts of the plant will occasionally stand under water and be difficult to access. Therefore, the customer sets high requirements on the pumps. Due to the limited space available, the pump installation was executed as a two-story construction. The installation had to be space-saving, compact and easily accessible for maintenance in the two-story setup.
The solution
The 19 pumps that Sulzer supplied are of the series XFP and AFLX. The AFLX series is designed especially for spacesaving installation in concrete shafts or steel riser pipes. All 19 submersible pumps are in wet installation. The maximum drive power is up to 400 kW. The heads of the large peak load pumps lie between 7 and 23 m, and the maximum flow is just under 2’000 l/s per pump. Thanks to their design, these IP68-classified submersible pumps are both flood-safe and very space-saving.
We are very happy that our pumps were chosen for the ecological reconstruction of the Emscher river.
