The SL and SE range of wastewater pumps now include medium, high and super-high hydraulic offerings from 12 to 42 hp. They are designed to handle raw unscreened sewage, effluent, and large volumes of surface and process water. The S-tube impeller enables free passage of solids up to 5 in. In addition, the pumps can adjust to changing operating conditions. The SL range is designed for submerged use, while the SE range accommodates both submerged and dry installations.
