The Grundfos MAGNA3 D circulator is the ideal choice for almost any building project, old or new. With its unrivaled energy efficiency, comprehensive range and integrated communications capabilities, MAGNA3 D is ideal for engineers and designers looking to create high-performance heating and cooling systems. The pump is maintenance free due to the fixed rotor type design. This also means that pump and motor form an integral unit without a mechanical seal and with only two seals. The bearings are lubricated by the pumped liquid. MAGNA3 D offers three multipump modes: alternating, backup and cascade operation.

In alternate and reserve operation, only one pump operates at a time, both ensuring constant comfort. In alternating operation, the transition from one pump to another depends on time or energy. If one pump fails, the other pump will automatically intervene. In standby operation, the standby pump is operated at intervals to prevent seizure. If the service pump stops due to a fault, the standby pump starts automatically. In cascade operation, the pumps turn on and off automatically, adapting to the power consumption of the system. The two pumps communicate wirelessly. MAGNA3 D features an intuitive display and allows you to connect wirelessly with the Grundfos GO Remote app, giving you access to advanced reporting and monitoring. The pump includes fieldbus communication via CIM modules, analog and digital inputs and configurable relays. Control functions include AUTOADAPT and FLOWADAPT. FLOWADAPT which reduces the need for throttling valves, thus reducing costs on system components. MAGNA3 D is the best choice for a wide range of heating and cooling applications, including:

• Mixing loop

• Heating surfaces

• Air conditioning surfaces

• Geothermal heat pump systems

• Smaller chiller applications.

MAGNA3 D is a single-phase pump and characterized by having the controller and display integrated into the control box. The pump also has an integrated temperature and differential pressure sensor. 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. MAGNA3 incorporates a 4-pole permanent magnet synchronous motor (PM motor). This type of motor is characterized by greater efficiency than a traditional squirrel cage induction motor. The speed of the pump is controlled by an integrated frequency converter.
