We suggest you to install two isolating valves Art. 552 (see Correlated Articles) before the pump unit to allow an easy service or replacement of the components of the unit.

The electronics of servomotor keeps constant the set temperature of the supply way, monitoring it by means of a sensor (included) mounted on the pipe. Display of the measured temperature and target temperature, on reversible LCD display.
Setting of target temperature adjustable from 0°C up to 99°C. Operating range of 90°.
Power supply 230V, 2 min, torque 6 Nm. IP42


Measuring and check of a DN25 system

  Clicking on the icon at side it is possible to download an Excel file dealing with the measuring and the check of a DN25 pump unit; it is possible to select the model and the working parameters, so getting a check of the power and of the residual lifting power. In case of underfloor heating system the surface that can be managed is approximately calculated. Changing the starting data it is possible to simulate different employment situations and to make your considerations.
