The newly developed free-flow impeller for waste water pumps will be the trade fair highlight showcased by KSB at this year’s Ifat in Munich. The F-max impeller now incorporates different distances between its blades, which are arranged in groups with two small and two large distances. Thanks to this asymmetrical blade arrangement, the F-max offers impressively wide free passages ensuring that even larger rigid solids pass easily and are reliably handled by the pump.
A further focus for KSB’s engineers when designing the blades was their ability to create a swirl in the hub area. This swirling effect shifts fibres away from the impeller hub and transports them to the outside.
