Grundfos : Grundfos UPS/Alpha 2

Grundfos UPS/Alpha 2


The circulator pumps in cast iron pump housing version are specifically designed for heating systems. For underfloor heating systems, it is advisable to use the stainless steel version, type Alpha N and UPS N, as the pumped liquid may often become aerated, causing an ordinary cast iron pump housing to corrode.



  • UPS can be operated at three speeds
  • ALPHA 2 automatically controls the differential pressure by adjustment of pump performance to the actual heating demand, without the use of external components



Available in various models – see the .pdf file for further technical details.
