    Features:



    The SMD immersion agitators are made entirely of stainless steel. The efficiency optimized propeller is directly driven by the motor.


    The squirrel-cage induction motor (efficiency class IE3) is protected against overload with the help of three bimetallic thermal switches (PTO) built into the windings. Optionally, the submersible agitators can also be equipped with three thermistors (PTC sensors).

    .

    To prevent the surrounding liquid from penetrating, the SMD submersible agitators have a multi-stage sealing system consisting of lip seals as a pre-seal that presses against the wear ring and a double mechanical seal in cartridge design. The sealing surfaces of the outer mechanical seal are made of silicon carbide/silicon carbide and the sealing surfaces of the inner mechanical seal are made of synthetic carbon/ceramic.



    SMD submersible agitators from 1.9 kW are equipped with a humidity switch as standard. For submersible agitators up to 1.8 kW, a moisture switch can be installed as an option.


    For SMD submersible agitators from 1.9 kW, the oil-filled seal housing can be monitored for water ingress using an optional leakage sensor. In the event of moisture ingress, an alarm signal is emitted by the sensor and/or the motor is switched off. For this purpose, the sensor must be connected to the Grundfos relay ALR-20/A.



    The stainless steel shaft is supported with the help of two permanently lubricated ball bearings.


    Motor power ranges from 0.9 to 3.5 kW.



    A variety of stainless steel or galvanized steel accessories are available for easy installation and trouble-free operation.
