THE EASY CHOICE FOR TOUGH WASTEWATER PUMPING
Flygt’s self-cleaning non-clog N-pumps deliver high sustained efficiency and reliable operation in a broad range of tough wastewater applications, including unscreened sewage, wastewater and sludge up to 8 percent solids concentration.
Flygt N-pumps can handle capacities up to 1,760 l/s (26,600 gpm) with motors from 1.3 to 680 kW (1.5 to 870 hp) and pumping heads up to 100 m (350 ft).
Choose a hardened cast iron impeller for typical wastewater applications or the chopper version for your toughest applications with long fibers and heavy solids. Hard-Iron impellers are highly recommended for applications with sand, grit and other abrasives, as well as wastewater mixed with sea water. For special applications such as highly corrosive wastewater environments we offer impellers in duplex stainless steel.
Flygt has nearly 100 years of experience in wastewater pumping and has installed more than 1 million wastewater pumps globally. With our proven technology, expertise in wastewater pumping applications, and responsive service network, Flygt N-technology pumps provide more than a product.
