The BritTherm B3 25/7-130 Circulator Pump is a cutting-edge automatic pump designed for efficient circulation and recirculation of potable water. Featuring nine intelligent modes, including AUTO, fixed speeds, constant and proportional pressure settings, plus an energy-saving night mode, this 130mm pump adapts seamlessly to your system’s demands, providing optimal performance while conserving energy.

The BritTherm Circulator Pump B3 25/7-130 brings advanced intelligence to water circulation with nine built-in modes designed to meet the specific needs of potable water systems. Users can choose from three fixed speeds for manual control or select AUTO mode for automatic optimisation of the pump’s operating range.

Two constant pressure modes (CP1 and CP2) maintain stable pressure in circulation and recirculation, regardless of flow rate changes. Additionally, two proportional pressure modes (PP1 and PP2) adjust pump output in proportion to flow variations, ensuring efficient, precise operation. The night mode reduces power consumption to a mere 5 watts during low-demand periods, maintaining system integrity with minimal energy use.

This pump also features electrical and thermal protection systems that safeguard against breakdowns caused by external conditions unrelated to pump operation, ensuring durability and reliable performance in domestic and commercial heating systems.
