Grunfos UP Series Domestic Hot Water Circulators

Grundfos has developed several circulator pump models to meet the needs of custom domestic hot water recirculation systems.

  • Bronze and stainless steel models are available to resist the corrosive effects of fresh water
  • Timer models conserve energy since they can be set for desired operating times during the day
  • Line cord models provide convenience to the installer because no pre-wire of the pump is required
  • Models are available with built-in check valves to prevent back flow
  • Aquastats can be incorporated into the circulator for additional savings
  • Bronze housings with 1/2" and 3/4" sweat (B5 and B7)
  • Stainless steel housings with union threaded connections (SU)
  • Stainless steel with flange connections (SF)
  • Built-in 6 ft. , 115 volt ac line cord with a NEMA 3-prong male plug (LC)
  • Built-in line cord and 24-hour programmable timer (TLC)
