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.
