Since the consumption of hygiene and disposable cleaning cloths has increased significantly in recent years and these tear-resistant solids are often disposed of improperly via the toilet, they accumulate in ever larger quantities in the sewers. When it rains, they reach the pumping stations, where they can get stuck in conventional pump models and lead to blockages. To this end, we have developed a solution that has already proved successful in numerous pumping stations and was presented at this year's IFAT in Munich: The pumps of the <link https: www.homa-pumpen.de en waste-water-and-sewage-systems products submersible-pumps-for-sewage-and-effluent-mxs-50-hz external-link-new-window>EffTec series are equipped with a permanently cooled motor and a highly efficient hydraulic system which prevents the cooling jacket from clogging with solids. The impeller and pump chamber have been redesigned and optimized using flow simulation software. In addition to clog-free operation, hydraulic efficiency has also been improved to up to 81 percent - for optimum service life.
