Peculiarities of this “Super-Impeller” are the screening of the pales and the no clogging profile.
The screening of the pales generates a flow in the impeller, so that a channel effect adds to the traditional vortex due to this hydraulic and increases the performances. The typical “no-clogging profile” is obtained through a particular structure of the impeller hub:
having no sharp edges, it doesn’t allow any hold for the long fibres.
