The Grundfos Comfort PM range includes circulating pumps for domestic hot water provided with a lead-free pump body compatible with drinking water, intended for houses or apartment buildings, driven by a powerful, 12-pole, permanent magnet single-phase motor. Some models in the range are equipped with the AUTOADAPT function that has been developed for domestic hot water systems including storage tanks (version A). In domestic hot water systems incorporating a temperature control to increase/decrease the temperature at the loop, Grundfos recommends the use of COMFORT BX or COMFORT B models. AUTOADAPT saves up to 48% of thermal energy and 96% motor energy compared with a standard pump in continuous operation. The "Rinse function" reduces the risk of contamination of networks by legionella (if the function is supported by the system). Version A) Automatic detection of weekends and holidays (version A). Setting the temperature (to be selected by means of the push button). Continuous operation (to be selected by means of the push button) Quick and simple electrical installation due to the ALPHA connector Circulator pump that is very reliable due to the detection of dry-running. Easy to clean, scale-resistant spherical rotor. Wear-free operation due to bearings lubricated with circulating liquid. Easy maintenance and cleaning due to the easy-to-disassemble pump head. Corrosion-resistant, lead-free brass pump body. No need for additional control regulator due to the integrated motor electronics
