Pressure tank
On the pump delivery side there is a membrane expansion vessel, which gives the possibility of
maintaining the pressure inside the piping when the system is not being used. The unit stops the
pump from continuing to run at zero demand and reduce the size of the tank that is required for
supply purposes.
Select a vessel suitable for the system pressure, and pre-load it in accordance with the values
indicated in the Quick Startup Guide (code 001080128).
