The Amamix propeller hydraulics have been optimised by KSB to achieve maximum efficiencies and good running properties when handling higher viscosity media. The redesigned propellers of the direct-drive submersible mixers ensure efficient thrust generation in the tank and thus reduce the operator’s energy cost. Available with nominal diameters from 200 to 600 mm, the stainless steel propellers have two or three blades – depending on the power input – and throw off fibrous, stringy substances entrained by the flow. This prevents the mixer from clogging up. A dynamic sealing system consisting of two mechanical seals (SiC/SiC) and a lip seal makes for the high operating reliability of the mixer and allows it to be run for up to 16,000 h without oil change. With power ratings ranging from 1.25 to 10 kW, the power output can be matched to the application. Individually stripped, tinned and resin-sealed conductors make the cable entry watertight.
