019 share Flygt Slimline Propeller Pump Flygt slimline propeller pumps are designed to transport large volumes of water at low heads with the ultimate in performance. The slimline profile combined with N-technology brings the advantage of small pump station size as well as sustained high efficiency. SMALLER FOOTPRINT The small profile of the new slimline propeller pump means less space is required for the pump station. The smaller pump profile fits to smaller column pipes. Since the pump bay width is determined by the column pipe diameter, the pump station footprint is thus reduced. The smaller the station, the less the investment needed for excavation, concrete and construction labor. At the same time, the slimline propeller pump brings advantages in sustained high efficiency and minimal maintenance, reducing demands on your station in operation. Video Flygt Slimline Introduction HIGHER RELIABILITY Flygt propeller blades feature patented N-technology with the backswept design of the leading edge. This sweeps debris away from the propeller along the relief groove located in the wear ring. Specially designed guide vanes help force debris out of the pump housing by the strong turbulent flow created within. These self-cleaning capabilities minimize soft and hard clogging, contributing to increased reliability, less maintenance and no unplanned stops. The reliability of Flygt slimline propeller pumps is reinforced by an overall robust design with hard iron wear ring, short shaft overhang and lifting and cable handling system. All of our propeller pumps are factory tested to verify high performance and premium quality BETTER EFICIENCY In operation, sustained high efficiency is enabled by the propeller’s optimized load distribution. This ensures peak propeller performance as well as suppressing flow separation losses due to the flow path curvature in the guide vane passage. Additionally, the pressure profiles have been further refined to increase efficiency and cavitation performance. The even velocity distribution, without dead zones and recirculation in the guide vane area, has been accomplished while keeping the area expansion in the division of the discharge low. All this adds to a state-of-the-art pump efficiency. Superior clog resistance is enabled with proven N-technology, with its swept leading edge, further contributing to sustained high efficiency.
