Designed for medium-to-high flow rates, the Flygt N 3315 wastewater pump series provides efficient clog-free performance to achieve the lowest overall life-cycle costs. It is available with a variety of cooling system options, monitoring sensors, and impeller material options. It can be delivered for wet or dry installation (P, S, T, Z) and in explosion-proof versions. Flygt N-Technology for Pumping Efficiency Flygt N-pumps take on the toughest applications and get the job done, while lowering your power consumption and maintenance costs. By preventing both soft and hard clogging, the self-cleaning N-technology impeller delivers sustained high efficiency. 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. Due to the mechanical self-cleaning impeller design, a sludge concentration up to 8% can easily be pumped. Wear-Resistant Impeller Materials Flygt Hard-Iron N-impellers were developed specifically for tough wastewater applications. While hardened grey iron impellers are available for typical wastewater applications, the Hard-Iron impeller provides superior wear resistance 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 also available, for applications requiring a high resistance to corrosion. The replaceable impeller wear ring is available in both Hard-Iron and grey iron.
