Grundfos electronic circulator MAGNA3 40-150 FN cod. 97924352

The MAGNA3 circulation pump from Grundfos is the ideal choice for almost all construction projects, old or new.

With its unmatched energy efficiency, full range and integrated communications capabilities, MAGNA3 is ideal for engineers and designers looking to create high-performance heating and cooling systems.

The pump requires no maintenance due to the encapsulated rotor type design. This also means that the pump and motor form an integral unit without a mechanical seal and with only two gaskets for sealing.

The bearings are lubricated by the pumped liquid.

MAGNA3 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 features include FLOWADAPT, which reduces the need for butterfly valves, thus cutting costs on system components.

MAGNA3 is the best choice for a wide range of heating and cooling applications, including:

• Mixing circuits
• Heating surfaces
• Conditioning surfaces
• Geothermal heat pump systems
• Smaller refrigeration applications.

MAGNA3 is a single-phase pump and characterized by having the controller and control display integrated into the control box.

The pump also has a built-in temperature and differential pressure sensor.

The pump body is available in both cast iron and stainless steel versions.

The composite rotor 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 higher efficiency than a conventional squirrel cage induction motor.

The speed of the pump is controlled by an integrated frequency converter.
