Grundfos COMFORT pumps, are specifically designed for recirculating domestic hot water in pressurised systemsThe pump is equipped with a spherical motor. Unlike the conventional canned-rotor motors, the spherical motor does not have a rotating bearing shaft. The stator transfers the magnetic field to the rotor in the water-conducting part of the pump. The pump is only suitable for pressurised hot water systems.The water-conducting part of the pump is hermetically separated from the stator with a stainless steel spherical separator.Features and BenefitsThe pump is characterised by:Lowest energy consumption and highest comfort due to the unique AUTOADAPT (only AUTO version)High-quality bearing
