KSB - New High-Efficiency Mixers

At the IFAT trade fair 2024 in Munich from 13 to 17 May, the KSB Group will present the latest generation of its AmaProp mixers for use in the sludge and biological waste water treatment.

The electric drives are either IE5 Ultra Premium Efficiency synchronous reluctance motors or IE3 Premium Efficiency asynchronous motors with ratings from 0.85 to 20.0 kW. Unlike conventional synchronous motors, the IE5 synchronous reluctance motors are made without any magnetic materials such as rare earths that are categorised as critical raw materials since their extraction causes severe environmental impacts in their countries of origin.

The necessary shaft sealing is performed by two bi-directional mechanical seals in tandem arrangement with a liquid reservoir. The latter is filled with environmentally friendly, ecologically acceptable white oil. An oil sensor fitted at the mating ring of the mechanical seal triggers an alarm if any damage occurs to the mechanical seals.
