N-Technology Wastewater Pump

Flygt N-technology has a mechanically self-cleaning design that handles the toughest modern wastewater challenges.

Even with today’s increase in non-organic, fibrous solids, Flygt N-impellers prevent soft and hard clogging. Most solid objects entering the pump will pass through the impeller between the impeller vanes. If an object gets caught on the leading edge of one of the vanes, it will slide along the backswept shape toward the perimeter of the inlet and be guided out through the relief groove.

By preventing build-up on the impeller, Flygt N-technology is able to deliver sustained high efficiency, minimize pump operating hours, and reduce unplanned service calls. The self-cleaning design can easily handle a sludge concentration up to 8%.

N-Impeller Material Options

Flygt N-impellers are available in three material options to provide long-lasting operation in various wastewater media.

For typical wastewater applications with low amounts of corrosives, hardened grey iron impellers can be suitable. For abrasive and corrosive applications, Flygt’s Hard-Iron (60 HRC) impeller has demonstrated five times greater wear resistance compared to standard grey iron material. A duplex stainless steel impeller is available for applications requiring a high resistance to corrosion.

The accompanying impeller wear ring is available in both grey iron and Hard-Iron.
