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.
