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.

  • Intelligent control mode options ensure the MAGNA3 is optimized to meet application demands:
    • AUTOADAPT automatically adjusts pump operation to meet system demands and reduces energy consumption by up to 85%
    • FLOWLimit restricts maximum flow and reduces the need for pump throttling valves
    • FLOWAdapt combines the functionality of AUTOADAPT with FLOWLimit
    • Differential temperature control adjusts the pump’s flow
    • Range of proportional pressure curve settings
    • Range of constant pressure curve settings
    • Range of constant curve/constant speed settings
  • Electronically commutated motor uses less than 50% of the energy of a standard motor
  • 360 [mNm] starting torque clears pump of system debris and sediment
  • Magnetite resistant design ensures longer life
  • Full range of single circulators in both cast-iron and stainless steel with twin models available for three largest operational capacities
  • Integrated pump, motor and control saves time and costs with easy installation
  • Easy to use, intuitive controls with LED indicator
  • Wireless multi-pump control includes a built-in wizard, making connection to a parallel coupled pump quick and easy
  • Built in diagnostics assist troubleshooting, energy tracking and logging without need for additional equipment
  • Automatic night setback ensures that MAGNA3 runs on the minimum curve when the built-in sensor registers a temperature drop
  • Wet rotor design allows for maintenance free and quiet operation
  • Innovative Grundfos Eye provides visual indication of pump status: pump running, warning or alarm
  • Grundfos GO lets you use your smart phone to access interface, regardless of pump location
  • No external motor protection required, insulating shell supplied with pump
