MAGNA1 circulator pump - heating, cooling, hot water



With the addition of the MAGNA1 range Grundfos can now deliver the required high energy efficiency, but with a reduced set of features. These pumps can offer the perfect solution in a refurbishment situation where you need to either replace a Grundfos UPS product or one of the smaller models from the original Magna family. These pumps are designed for circulating liquids in heating systems with variable flows where it is desirable to optimise the settings of the pump duty point, thus reducing energy costs.

The MAGNA1 range of circulators comes complete with electronically controlled motors that are based on permanent magnet (PM) and stator technology. They are designed for circulating liquids in a wide range of light commercial and commercial applications including:

  • Heating systems
  • Air conditioning and cooling systems
