Frequency inverter

Sirio - Frequency inverter for pressure constant

Sirio Entry


  • Electronic speed control and pressure constant of electric centrifugal pumps
  • Pressure-dependent on/off, as well as automatic adjustment of the pump performance to varying operating conditions
  • Energy saving and noise reduction through speed control
  • Dry running protecion with automatic shutdown and restart the pump
  • Soft start
  • Digital pressure indicator on the display (Menu language English, German, French, Italian and Spanish)
  • Protection against overvoltage, undervoltage and phase failure
  • Erating status is displayed by LEDs (power, alarm / leak / dry run, pump on)
  • Mounting vertically or horizontally

Sirio WiFi-module

The WiFi module SR5V is a small device for mobile access, which can be mounted in the Sirio and forms a WiFi access point. With the help of an interface **, the user can access the Sirio via a WiFi connection from a mobile device and so perform parameter settings or monitoring. It also allows to diagnose error or warning messages.
Attention: Installable only in current new models, can not be retrofitted in older models.
** Use of this interface is subject to a charge
