The Flygt N-3085 impeller moves axially to improve flow and help eliminating clogging under difficult of conditions. When detritus enters the volute, the patented N-hydraulic pushes them from the centre to the perimeter of the inlet. Moving axially also enables very large detritus to get through. The impeller design is coupled to a specially developed relief groove and is self-cleaning.

ITT says that the new impeller significantly improves the anti-clog characteristics of the company’s Flygt N series of pumps. "This is a giant step in the development of our N-range for wastewater pumping," says Ulf Arbeus, R&D Director of ITT Water & Wastewater.
