Submerged wastewater pumps

Owing to their design, our submerged wastewater pumps are centrifugal pumps. Their hydraulics, together with the motors, can be completely immersed in the medium and, depending on the model, can overcome a head of up to approx. 60 meters. OSNA’s robust submerged wastewater pumps are particularly suitable for use in cold water and waste water contaminated with solids. The TMP and Söffel submerged wastewater pump models are used in municipal wastewater collection basins, pump shafts and drainage systems in multistory parking garages, in agriculture and in industrial plants. Because the surrounding water strongly muffles the operating noise of submerged wastewater pumps, these pumps are almost inaudible in use.
