FLENDER transmission units for aerators

The aerator is an agitator unit in the biological part of the waste water treatment plant. It whirls up the water at the surface so that it can be enriched with oxygen. The bacteria are activated and withdraw the degradable materials from the waste water.

The agitator unit hangs at a certain distance on the vertically downward mounted driven shaft of the gear. To prevent polluting the waste water with transmission oil FLENDER gears are built with a driven shaft which is equipped with an oil-dam-pipe and a contact-free and non-wearing shaft seal.

The axial and transverse forces which result from the process are absorbed by heavy duty output shafts and output bearings.
