Grundfos SE2.110.250.220.4.52L.N.51D.A 99776922 Submersible wastewater pumps
Product code: 99776922
EAN Number: 5713834120527
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 operation. The cooling jacket ensures that the pump can operate submerged or dry installed. 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.
