SL1.95.100.220.4.52H.N.51D.A
The non-self-priming single-stage centrifugal pump is designed for handling wastewater, process water, and unfiltered raw sewage. This pump is designed for both intermittent and continuous operation when installed submersibly. The revolutionary S-tube® impeller provides circular passages and can handle solids with a size of 95 millimeters, making it suitable for wastewater with a dry matter content of up to 3%. The SmartTrim impeller clearance adjustment system enables the pump to maintain optimal performance. For installation on an automatic coupling system, the Grundfos SmartSeal gasket system provides a leak-proof connection. The pump is equipped with an efficient Grundfos motor based on an IE3 motor assembly.
