Brochure & Specifications 

UPS 43-44 BFC

Grundfos UPS B circulator pumps have a bronze pump housing for drinking water applications while Grundfos UP N have a stainless-steel pump housing. Both variants are recommended for underfloor heating systems as the pumped liquid may often become aerated, causing corrosion in cast iron pump housings. The pump is of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. The pump is characterized by:

  • Ceramic shaft and radial bearings.
  • Carbon axial bearing.
  • Stainless steel rotor can and bearing plate.
