Grundfos is extending its SL and SE range of wastewater pumps to include medium, high, and super-high hydraulic offerings from 12 to 42 hp. The extended selection ensures high pump efficiencies over a wide range of demand and a large free passage of solids at low vibrations. With its hydraulically efficient S-tube impeller, it enables free passage of solids up to 5 inches. Intelligent and self-adaptive controls allow the pump to adjust to changing operating conditions, and high-efficiency motors meet or exceed global standards.
