Features

1. Micro thermal protector
   The built-in micro thermal protector (motor protection device) prevents possible motor burnouts due to overloading, impeller locking, or open phases.
   * 5.5/7.5 kW models incorporate the automatic cut-off function.
2. Motor
   Dry motors with class E insulation are used. (Motors with class F insulation are also available.)
3. Discharge connection
   Submersible pump is automatically connected to the discharge pipe.
4. Cable entry
   Core sealing is employed to prevent water leakage into the motor chamber by blocking water that streams along the core wires even if the cable sheath is damaged or the end of the cable is immersed in water.
5. Impeller
   The most suitable non-clogging type impeller, either volute or volute mixed flow type, can be selected for the application.
6. Shaft seal
   The double mechanical sealing, made of highly wear-resistant material, at the upper and lower parts prevent water leakage into the motor chamber.
7. Leakage detector
   Deterioration of the motor insulation is prevented by the immersion detector that activates when water penetrates into the motor chamber.
