The Flygt N 3531 series manages large volumes of water in wastewater, stormwater, treatment and industrial applications. Industry-leading self-cleaning N-hydraulics help ensure optimal energy consumption, extended asset life, and fewer pump station visits to minimize operational costs and environmental impact. N 3531 pumps are available with Hard-Iron, grey iron, or stainless steel impellers; in explosion-proof and standard versions; and for submersible or dry, vertical or horizontal installation (configurations P, T and Z). Self-cleaning N-technology impeller Flygt N-technology hydraulics pair backswept leading edges on the impeller vanes with a stationary relief groove to provide a mechanically self-cleaning hydraulic design. The backswept leading edges sweep solids away from the impeller hub toward the perimeter of the inlet, where they are caught inside the relief groove and pushed out of the pump. The result is clog-free pumping that reduces call-out costs by up to 40% and energy consumption by up to 25%, compared to pumps with conventional impellers. A sludge concentration up to 8% can easily be pumped. Flygt’s Hard-Iron material (60 HRC) delivers prolonged impeller life in even the toughest wastewater applications.
