Landustrie is refurbishing 5 Archimedes screw pumps of the inlet pumping station, located at the largest sewage treatment plant in German federal state Baden-Württemberg, here STP Stuttgart-Mühlhausen (1.2 million IE). The screw pumps, now due for renovation, lift waste water from the secondary settling tank into the sand filter but are also operational in case of floods, ensuring continuos operation of the sewage works.
Four existing screws are refurbished and one new Landy Archimedes screw pump is delivered. This new screw dimensions 2.6 m diameter and 12.1 m length.
In our own production facilities in Sneek, the four existing screws are blasted and provided with a new coating.
After full repair, the screw pumps with new drive units and new Landy lower and upper bearings, are reinstalled on site by our own team of field service engineers.
