The Flygt N 3171 medium capacity pump series delivers outstanding, cost-effective performance for a variety of water and wastewater applications. It provides exceptional media handling capabilities, featuring explosion-proof versions and impeller material selection from Hard-Iron, grey iron or stainless steel. Flygt N 3171 pumps can be delivered for submersible or dry installation (configurations P, S, T, Z). N-Technology Hydraulics for Trouble-Free Pumping With a self-cleaning impeller design, Flygt N-pumps deliver clog-free pumping and sustained energy efficiency. Today’s wastewater often includes heavy loads of non-organic, stringy solids that can clog conventional pumps. Flygt N-technology sweeps objects through the pump to prevent build-up that would otherwise reduce pump 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 design, a sludge concentration up to 8% can easily be pumped and unplanned maintenance is significantly reduced. Impeller Materials for Tough Applications Wastewater chloride content, pH value, temperature, oxygen content, abrasives and flow are all factors that should affect the selection of impeller materials.
