Outstanding features include extremely quiet operation and self-suction capacity of up to 2 m, which is considerably increased with the installation of a foot valve.

Its reliability is added to its control capability thanks to the integration of the constant-pressure control mechanism, which regulates the starting and stopping of the pump, leaving the installation pressurised at all times.

They are particularly recommended for pressurisation at constant pressure.
