It is a type of pump traditionally and historically manufactured by Alfa. It has been designed to empty the settling pits and therefore to transfer even particularly thick sludge (up to 2kg/dmc).
The pump is immersed in the thick sludge which falls into the body of the pumping unit, which is completely metallic with spheroidal cast iron impeller.
