BritTherm Сirculator Pump S3 Series S3 25/5-130 (661999305)

The BritTherm S3 25/5-130 Circulator Pump offers advanced, automatic operation for efficient circulation and recirculation of clean potable water. Built with a stainless steel EN1.4521 casing, this pump features nine intelligent operating modes, including three fixed speeds, AUTO mode, constant and proportional pressure settings, and a low-energy night mode. It adapts seamlessly to varying water system demands, ensuring reliable, energy-efficient performance.

The BritTherm Circulator Pump S3 Series S3 25/5-130 is engineered to provide smart, automatic water circulation and recirculation in potable water systems. Its robust stainless steel EN1.4521 casing ensures long-lasting durability and corrosion resistance.

This model includes nine intelligent operating modes designed to suit diverse plumbing and water supply requirements. Users can choose from three fixed speeds for manual control or activate AUTO mode, which intelligently selects the optimal pump performance based on system needs.

Two constant pressure modes (CP1 and CP2) maintain stable pressure regardless of flow fluctuations, while two proportional pressure modes (PP1 and PP2) adapt pump operation proportionally to changes in flow rate, maximising efficiency.

The Night Operating Mode significantly lowers energy use to just 5 watts during periods of reduced demand, preserving system integrity without wasting power.

Electrical and thermal protection systems help safeguard the pump against damage caused by external faults unrelated to normal operation, enhancing reliability and lifespan. The BritTherm S3 25/5-130 is ideal for modern potable water circulation systems seeking smart, adaptable, and energy-efficient pumping solutions.
