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. |
