Description
The Grundfos MAGNA1 circulator pump is the simple option for a job well done. With its high energy efficiency the product lives up to the EuP 2015 regulations ensuring substantial savings on electricity, and with its intuitive, user-friendly interface and maintenance-free design, MAGNA1 is the ideal circulator pump for applications with basic performance needs. The pump is maintenance-free due to the canned-rotor type design. MAGNA1 can work as main pump in both heating and cooling applications, including:
•Mixing loops
•Heating surfaces
•Air-conditioning surfaces
•Ground-source heat pump systems
•Smaller chiller applications.
MAGNA1 is a single-phase pump and characterized by having the controller and operating panel integrated in the control box. The pump housing is available in both cast-iron and stainless-steel versions. The composite rotor can is carbon-fiber reinforced, the bearing plate and rotor cladding 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 synchronous, permanent-magnet motor (PM motor). This motor type is characterized by higher efficiency than a conventional asynchronous squirrel-cage motor. The pump speed is controlled by an integrated frequency converter.
