INSTALLATION AND USE

PRESFLO MULTI is an electronic device designed to control and protect single-phase domestic pumps with a power capacity of up to 2 HP. It is ideal for water supply and pressure boosting in residential settings, as well as for small-scale irrigation applications.

PRODUCT DESCRIPTION

※ PRESFLO MULTI features a pressure sensor and a flow sensor linked to an electronic system that automatically activates the pump when a faucet’s opening lowers the pressure below a specified level and deactivates it when the flow stops or dips under 2 l/min.
※ PRESFLO MULTI is also equipped with:
– Pressure Gauge
– integrated 1-litre expansion tank useful in case of leaks and to protect against water hammer;
– option to adjust the restart pressure from 1 bar to 5 bar;
– capability to set the maximum current up to 16 A

The integrated electronics protect the pump from:

※ dry running
※ frequent start-ups due to leaks in the system;
※ Overcurrent
