BritTherm Automatic Сirculator Pump P8 Series P8 65/12 (661996003)

The BritTherm P8 65/12 is a heavy-duty flanged circulator pump designed for commercial heating systems. It features a permanent magnet motor and compact rotor technology for quiet, efficient operation with low power consumption. With 16 automatic operation modes—including AUTO, constant pressure, proportional pressure, and fixed rotor speed modes—this pump offers exceptional versatility for diverse commercial HVAC requirements. The automatic night power reduction function minimises energy use without compromising heating performance, supported by electrical and thermal protection for enhanced reliability.

Built to meet the demands of commercial HVAC systems, the BritTherm P8 65/12 pump comes with a 65mm flanged connection and delivers a maximum head of 12 metres. Its permanent magnet motor and compact rotor design ensure whisper-quiet running while maintaining high energy efficiency, ideal for environments where noise and energy costs are a concern.

The pump’s 16 automatic modes provide flexible control options: AUTO mode activates with a single button press, suitable for approximately 80% of existing heating systems. Five constant pressure modes (CP1 to CP5) cater to stable flow rate applications, while five proportional pressure modes (PP1 to PP5) adjust dynamically for variable flow demands. Additionally, five fixed rotor speed modes (CS1 to CS5) allow traditional manual speed selection.

Energy efficiency is further improved with the automatic night power reduction feature, cutting power consumption down to 5 watts during low-demand periods without affecting heating quality. Robust electrical and thermal protection mechanisms guard against external damage unrelated to pump operation, ensuring longevity and dependable performance in commercial settings.
