Sewage Pumps with Mechanical Mixer
The mechanical mixer of WILO grit collector pumps is directly fixed at the impeller. Therefore the sand is only stirred up in the area of the pump entry, solidified sediments are loosened up to be pumped. The limited flow area does not prevent the sand from settling down.

Advantages:
– loosens up solidified sediments
– high resistance to wear
– non-clogging
– frost-proof and weather proof design
– high power reserve
– little maintenance required
