Automatic protections

Thermal protection

Thermal protection

The ZDJet.P complete submersible pump is automatically protected against motor overheating. This can happen because of: the high temperature of the pumped liquid; when the minimum distance between the pump installed and the well bottom isn’ t respected; when the pump is installed in well/tanks bigger than 4” without a proper cooling system; when the pump works in shut-off. In such cases, the thermal protection system will stop the pump, which will automatically restart as soon as the correct working temperature parameters are restored.

Current overload protection

Current overload protection

The ZDJet.P complete submersible pump is protected against against overload. In case the pump is partially or totally blocked, it will automatically restart as soon as the correct working temperature parameters are restored.

Information on a proper installation

  • If you are using a generator with an internal combustion engine, it is necessary that the generator’ s power measured in kW (in continuous delivery) is three times the rated power in kW of the submersible pump.
  • We recommend to install a proper cooling jacket in installations bigger than 10 cm, to guarantee the correct motor cooling flow.
  • In order to reset the thermal protection, wait until correct working temperature parameters are restored.
