    Properties:



    The squirrel-cage induction motor is protected against overload with three thermobimetal switches (PTO) in the motor windings. The agitators are equipped with IE3 motor components.


    To prevent ambient liquid from entering, the SMG submersible agitators have two FKM radial lip seals and a ceramic-coated wear bushing, as well as a silicon carbide/silicon carbide or tungsten carbide/tungsten carbide mechanical seal, depending on the size. The sealing surfaces of the second mechanical seal, located between the gearbox and the engine, are made of synthetic carbon/alumina.

    .

    The oil-filled gearbox housing is monitored for possible water ingress by a leakage sensor built into the gearbox as standard. The sensor can trigger an alarm signal and/or shut down the motor using an external Grundfos relay type ALR-20/A.



    Tapered roller bearings are installed in the gearbox housing to support the axial forces of the propeller.


    The SMG series is available in power sizes ranging from 0.9 to 18.0 kW.



    A wide range of AISI 304/316 stainless steel installation accessories ensures easy installation and many years of trouble-free operation.
