BritTherm Automatic Сirculator Pump P8 Series P8 50/12 (661996002)

The BritTherm P8 50/12 is a heavy-duty flanged circulator pump built for commercial heating systems. Featuring permanent magnet and compact rotor technology, it ensures quiet, efficient operation with low power consumption. The pump offers 16 automatic operation modes, including AUTO, constant pressure, proportional pressure, and fixed rotor speed modes, providing flexible control to suit a wide range of commercial heating requirements. An automatic night power reduction function further enhances energy savings without compromising heating performance. Robust electrical and thermal protection systems safeguard the pump for reliable long-term use.

Designed for demanding commercial HVAC applications, the BritTherm P8 50/12 is a robust flanged pump with a 50mm connection size and a maximum head of 12 metres. Its permanent magnet motor combined with compact rotor technology delivers whisper-quiet operation alongside low energy consumption, making it an ideal choice for modern heating systems focused on efficiency and noise reduction.

This pump features 16 selectable automatic modes for tailored system performance. The AUTO mode offers easy one-button activation and suits around 80% of existing heating setups. Five constant pressure modes (CP1 to CP5) are perfect for systems with stable flow requirements, while five proportional pressure modes (PP1 to PP5) automatically adjust to fluctuating flow rates. Additionally, five fixed rotor speed modes (CS1 to CS5) allow for traditional manual speed control.

The built-in automatic night power reduction function cuts energy use to just 5 watts during low-demand periods, reducing running costs without impacting heating quality. Comprehensive electrical and thermal protections prevent damage from external factors unrelated to pump operation, improving durability and uptime in commercial environments.
