#CMT# #/CMT# The unit has a magnet gear (15) comprising an input side with an input side magnet ring (30) and an output side with an output side magnet ring (40) that is coupled to each other via magnetic fields, so that a transmission ratio exists between the input side and the output side. The output side drives an impeller. An electric motor (20) drives the magnet gear and coupled to the input side. An encapsulation (62) encapsulates the motor and the input side magnet ring in a fluid-tight manner and separates the input side magnet ring from the output side. #CMT#USE : #/CMT# Flow production unit e.g. recirculation pump, mixer and flow accelerator, for use in submerged operation of fluid in a sewage treatment work. #CMT#ADVANTAGE : #/CMT# The encapsulation encapsulates the motor and the input side magnet ring in a fluid-tight manner and separates the electric motor and the input side magnet ring from the output side of the magnet gear without the need for additional dynamic sealing on a drive shaft of the impeller or an input shaft of the gear, so that reliable and low-maintenance operation of the unit can be achieved. The pump has a significantly reduced maintenance expense. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic longitudinal sectional view of an electric motor and a magnet gear of a flow production unit. 15 : Magnet gear 20 : Electric motor 30 : Input side magnet ring 40 : Output side magnet ring 62 : Encapsulation. |
