Flygt Channel impeller C-pumps are built to handle capacities of up to 3,000 l/s (48000 gpm) with motors up to 775 kW (1050 hp). The base versions of these pumps are made in durable cast iron and are intended for demanding applications such as municipal sewage and industrial effluent. Explosion-proof versions are available. The classic C-pumps with shrouded single and multivane impellers have proven themselves over the years. The smaller C-pumps are equipped with the Flygt Nevaclog® impeller, which has large free passage solids-passing properties. The larger pumps have multi-vane impellers for maximum hydraulic efficiency and clog resistance.
