The pumps are designed to handle raw, unscreened sewage, effluent, large volumes of surface water and process water in municipal, utility and industrial applications. The solids-handling pump series is available with an SLV/SuperVortex Impeller or an SL1/S Tube Impeller.
 
The SLV/SuperVortex Impeller pump type provides the free passage of solids up to 4 inch in diameter, especially for liquids with a content of solids, fibres or gassy sludge. The SL1/S Tube Impeller pump also accommodates solids up to 4 inches, but is designed particularly for large flows of raw sewage.
 

Both models are designed for permanent submerged installation in demanding applications such as municipal wastewater, network pumping stations, wastewater treatment plants, public buildings, housing projects and other commercial applications. The series is designed with IE3 premium efficiency motor components, quick removable pump-housing clamps, cartridges seals, quick removable plug in cord, and smooth exterior components.
