Automatic protections

Overload protection

Overload protection

The ZDS Control Box protects the P.H3F Complete Solution against overload. In case the pump is partially or totally blocked, the overload protection in the ZDS Control Box stops the pump to protect it.

Information on a proper installation

  • The correct pump must be selected considering the delivery pressure and the characteristics of the plant.
  • During installation of the submersible pump, it is necessary to verify if the power supply voltage is correct.
  • The correct pump operation is guaranteed when the power cable section is correctly selected, considering the motor power and the distance between the pump and the plug itself.
  • 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.
  • To guarantee automatic operation mode (the pump starts and stops when open and close the tap) it is necessary to connect a pressure switch and a pressure tank of the correct size, if the plant is not already provided with them.
  • We recommend to install a proper cooling jacket in installations bigger than 10 cm, to guarantee the correct motor cooling flow.
  • The maximum quantity of sand allowed in the pumped water is 120g/m³.
  • In order to reset the overload protection sensor, it is necessary to press the appropriate button on the CBH.
