Xylem says fields tests conducted around the world validated significant improvements with Flygt Concertor, including: energy savings of up to 70% compared to a conventional pumping system; reduced inventory by up to 80% due to flexible performance; clog-free pumping operation and clean wet wells saving up to 80% in vacuum cleaning costs; and a compact design, reducing cabinet size by up to 50%. Flygt Concertor is suitable for use with wastewater pumps in the range of 2.2 to 7.3 kilowatts (kW) and has a system design that combines IE4 motor efficiency, N-hydraulics, integrated power electronics and intelligent controls. All these features are designed to work in harmony with each other, which results in optimal pumping performance at the lowest cost of ownership, according to Xylem. Flygt Concertor’s flexible performance represents a significant change in how pumping systems will be selected and managed in order to accommodate different flow rates. In contrast to the fixed performance curves of conventional pumps, Flygt Concertor offers a wide performance field from which to choose the right operating point. This makes selection simple, facilitates performance fine-tuning and, as a consequence, significantly reduces inventory. Furthermore, Concertor features a built-in sump and pipe-cleaning features – a first for a wastewater pumping system. Extensive trials show that these features, together with a second generation of Flygt’s patented Adaptive N-technology and an integrated pump-cleaning function, minimize vacuum cleaning costs. Flygt Concertor will be on display at IFAT, Munich, Germany, at Xylem booth number 451/550, Hall A6.
