Product code: 99776929
EAN Number: 5713834120664
Non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage. The pump is designed for intermittent and continous operations in submerged installation. The revolutionary S-tube® impeller provides free spherical passage of solids up to 110 mm and is suitable for wastewater with a dry matter content of up to 3 %. A SmartTrim impeller clearance adjustment system makes it possible to maintain maximum performance. For installation on auto coupling, the Grundfos SmartSeal gasket system provides a leak-proof connection. The pump comes with a high efficient Grundfos motor built on IE3 motor components. The pump is explosion-proof.
