The S4 Series Pump is a modern, intelligent automatic pump with a stainless steel EN1.4521 type casing and 9 intelligent operating modes for the circulation and recirculation of clean potable water, adaptable to the tasks and specifications of the water supply system.

- Three Fixed Pump Speeds (“Old School”) : Selectable by the touch of a single button, allowing the use of the entire range of pump power.

- AUTO Mode : Activated by pressing one button, the automation determines the optimal operating range of the pump for the current circulation and recirculation system, minimising energy consumption without compromising performance.

- Two Constant Pressure Operating Modes (CP1 and CP2) : Maintain constant pressure in circulation and recirculation systems, regardless of flow rate.

- Two Proportional Pressure Operating Modes (PP1 and PP2) : Adjust the pump operation in proportion to flow rate changes, ensuring optimal performance based on system demands.

- Night Operating Mode : Reduces energy consumption to 5 watts, maintaining system quality without unnecessary operation during low-demand periods.

- Electrical and Thermal Protection : Safety systems that prevent pump breakdown due to external reasons not related to the operation of pump systems.
