Inverter for three-phase electric pump control / Sirio




Sirio is a VFD (Variable Frequency Driver) for pumps. Sirio was made to control the pump’s speed and hold the pressure to a constant value within the hidrofor system. Not only controls the pump, but protect it from:

  • Dry running
  • Over current

It has a display to show the values of the pump (current absorption, pressure, frequency etc…) and can be set with the buttons on the interface. Sirio must be installed on the pipe system in any position, but according to the flow direction.

If the pump stops by an error, Sirio will display the source of the error, and restart the pump according to the restart parameters.
