Turbelle® nanostream® combines aesthetics and function; it creates new ideas. This innovative circulation pump sets up a new record: At a diameter of only 70 mm (2.7 in.) it enables a water flow of 4,500 l/h (1,189 USgal./h) at an energy consumption of only 7 W. The pump contains a very large prime strainer for the water drawn in which prevents premature soiling.
