Rotating positive-displacement pumps have been used for decades in wastewater and sludge treatment as handling systems for all types of substances. Due to their regulatory properties, these pumps deliver secure, dependable, and efficient processing.
Along with sand additives, wastewater being treated often contains coarse floating pollutants, decomposing matter, sludge-generating particulate materials, dissolved organic matter and bacteria.
None of these substances present any problem for NETZSCH Pumps and Grinding Systems: Our NEMO® Progressing Cavity Pumps and NETZSCH TORNADO® Rotary Lobe Pumps, along with the NEMO® M-Ovas® provide you with the optimal technical solution for your application.
