PRESFLO VARIO 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. PRESFLO VARIO 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 VARIO has a knob for quick and intuitive adjustment of the restart pressure from a minimum of 0.8 bar to a maximum of 2.4 bar.
