RETRACTED VORTEX IMPELLER
The impeller offers reliability against clogging due to the feature of wide through passages, and a good resistance to wear thanks to the absence of shimming. The versatility of use compensates for this impellers somewhat lower efficiency.
The impeller can be reduced in dimension to offer different characteristics.
For water containing a large amount of solids and long fibre, sewage with a high gas and sludge content.
SINGLE-CHANNEL IMPELLER
It offers reliability against clogging and features wide through sections and a good resistance to wear, low mechanical action on the fluid, high hydraulic efficiency.
Particularly suitable for clean water, water containing solid and fibrous solids, cloacal water, sewage and sludge.
Low vibrations thanks to the dynamically balanced impeller.
DOUBLE CHANNEL IMPELLER
It offers reliability against clogging and features wide through sections and a good resistance to wear, low mechanical action on the fluid, high hydraulic efficiency.
Particularly suitable for clean water, water containing solid and fibrous solids, cloacal water, sewage and sludge.
Low vibrations thanks to the dynamically balanced impeller.
SHREDDER
Made of very hard stainless steel, the shape of the shredder ensures long-life and fade-free shredding capacity.
Waste water disposal from gas stations, community housing and neighbourhoods.
No particular tools are required to replace this part.
