Grundfos single circulator MAGNA1 50-120 F code 99221336

The Grundfos MAGNA1 circulator is the simple option for a job well done. With its high energy efficiency, the product is up to the EuP 2015 regulations ensuring significant savings on electricity, and with its intuitive and easy to use interface and maintenance-free design, MAGNA1 is the ideal circulator for your needs. of basic performance in applications where basic system control and monitoring are desired. With this range of circulators, everything from setup to basic control and monitoring is simple. The pump is maintenance free due to the fixed rotor type design. MAGNA1 offers the possibility to monitor the pump via the fault relay output. The digital start / stop input remotely controls the pump. The pump communicates wirelessly with the Grundfos GO Remote app. MAGNA1 can function as a master pump in both heating and cooling applications, including:

  • Mixing loop
  • Heating surfaces
  • Conditioning surfaces
  • Geothermal heat pump systems
  • Applications for smaller chillers.

MAGNA1 is a single-phase pump and characterized by having the controller and operation panel integrated in the control box. The pump body is available in both cast iron and stainless steel versions. The composite rotor case is reinforced with carbon fiber, the bearing plate and rotor liner are made of stainless steel, and the stator housing is made of aluminum. The power electronics are air-cooled.

The pump incorporates a 4-pole permanent magnet synchronous motor (PM motor). This type of motor is characterized by higher efficiency than a traditional squirrel cage asynchronous motor. The pump speed is controlled by an integrated frequency converter.
