Conforto KM
Heavy-duty submersible sludge pump with an open single-groove impeller, 4–7.5 kW
Official partnerConforto KM are two-pole three-phase submersible pumps for heavy-duty applications in the industrial, agricultural and civil sectors — draining clean and dirty waters containing suspended and filamentous matter, activated or untreated sludge. The impeller is a highly efficient open single-groove type, and the casing comes with a DN 65 or DN 80 flanged delivery. Three seals: an upper alumina/graphite seal, an intermediate silicon carbide seal and a lower lip seal, the two lower ones lubricated from an oil sump. A conductivity sensor in the sump monitors the presence of the lubricating fluid.
