SL submersible wastewater pumps (photo) are designed to handle raw sewage, effluent and large volumes of surface and process water in municipal, utility and industrial applications. The solids-handing pump series, with motor ranges from 1.5 to 15 hp, is available with two types of impellers: the SLV SuperVortex Impeller and the SL1/S Tube Impeller. Both impeller types allow for the free passage of solids up to 4 in. in diameter, making them suitable for liquids with a content of solids, fibers or gassy sludge. The SL1/S pump type is designed particularly for large flows of raw sewage. — Grundfos Pumps Corp., Downers Grove, Ill.
