Xylem’s compact pump range features a patented Adaptive N technology designed to pump wastewater efficiently and reliably in commercial buildings and municipal sewage applications.
How Adaptive N technology works: When solid objects such as stringy fibrous material and modern waste enter the inlet of a conventional pump, they tend to get caught on the leading edges of the impeller vanes. This build-up reduces the impeller’s efficiency, resulting in more unplanned callouts and increased energy consumption.
Adaptive N technology overcomes this in two stages:
Stage 1: 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 towards the perimeter of the inlet.
Stage 2: The solid object will slide along the tip of the impeller vane inside the relief groove. The guide pin in the insert ring will push all types of solids away from the center of the impeller, along the leading edge and out through the relief groove. If the debris is bulky the Adaptive N impeller moves axially upward when required allowing it to pass through smoothly.
In addition to maximum reliability due to its self-cleaning capability, Flygt’s Adaptive N technology also lowers energy consumption up to 25 percent. The innovative hydraulic design of the new pump range is offered with three different materials; hard-iron, grey iron and stainless steel.
