Grundfos 97924271 Magna3 40-150F PN6/10 230V Circulating Pump

The Grundfos MAGNA3 model D circulator pumps are designed for circulating liquids in systems with variable flow requirements

where you want to optimize the setting of the pump duty point, thus reducing energy costs.

Applications
Heating systems
main pump
mixing loops
heating surfaces
air-conditioning and cooling systems
domestic hot-water systems
ground source heat pump systems
solar-heating systems.

The MAGNA3 circulator pump is perfect for both new systems as well as for replacement. The pump is ideal when operating in systems
requiring an automated adjustment of pressure. This pump range is the best choice as it eliminates the need for an expensive bypass
valves and similar components. Furthermore, the pump is appropriate for systems with
hot-water priority as an external signal can immediately force the pump to operate according to the maximum curve, for example in solar-heating
systems. When using the pumps in domestic hot-water systems, please observe local legislation regarding pump house material.
Grundfos strongly recommend that you use stainless-steel pumps in domestic hot-water applications to avoid corrosion.
