Product details

The Grundfos MAGNA3 circulator pumps are designed for circulating liquids in the following systems:

• Heating & cooling
• Ground source heat pump systems
• Hydronic venting
• Chilled water
• Snow melt
• Hot water recirculation
• BTU meter.

MAGNA3 is the ideal all-purpose circulator pump for commercial heating and cooling applications. The permanent magnet motor, AUTOADAPT function and integrated frequency converter, make MAGNA3 a cutting-edge piece of intelligent technology – retaining Grundfos’ unrivalled industry leading experience with electronic pumps. The upgraded MAGNA3-32 medium size model expands the range of this extremely energy efficient circulator into lighter demand applications including residential heating, cooling and hot water recirculation systems.

To ensure correct operation, it is important that the sizing range of the system falls within the duty range of the pump.
