The BritTherm Circulator Pump S3 Series S3 25/4-130 is a modern and intelligent pump engineered for circulation and recirculation of clean potable water. Constructed with a stainless steel EN1.4521 casing, it combines durability with high performance.

This pump provides nine versatile operating modes, allowing it to adapt to a wide range of water supply system requirements. Users can select from three fixed speeds for traditional operation, or activate AUTO mode to let the pump automatically adjust to the system's optimal performance range.

Additionally, two constant pressure modes (CP1 and CP2) maintain stable pressure regardless of flow rate, while two proportional pressure modes (PP1 and PP2) adjust pump output in response to flow changes, ensuring efficiency and system protection.

The Night Operating Mode lowers energy consumption to just 5 watts during low-demand periods, balancing energy efficiency with consistent system quality.

Safety is paramount, with electrical and thermal protection mechanisms preventing damage from external faults unrelated to normal pump operation. The BritTherm S3 25/4-130 is ideal for intelligent water circulation systems requiring adaptable, efficient, and reliable pumping solutions.
