Grundfos UP B circulator pumps have bronze pump housing for drinking water applications, while Grundfos UP N have stainless-steel pump housing. Both variants are recommended for underfloor heating systems, as the pumped liquid may often become aerated, causing corrosion in a cast-iron pump housing.

Choosing a stainless steel circulator ensures that you will always have the right pump - whether it is an open or closed system. Grundfos offers three stainless steel models, including two that feature our 3-speed SuperBrute technology.
