MAGNA3 40-80 F

The Grundfos MAGNA3 circulator pump is ideal for almost any building project – old or new. MAGNA3 is ideal for engineers and specifiers looking to create high-performance heating and cooling systems with its unrivaled energy efficiency, all-encompassing range, and built-in communication capabilities. The pump is maintenance-free due to the canned-rotor type design. This also means that the pump and motor form an integral unit without a shaft seal and only two gaskets for sealing. The pumped liquid lubricates the bearings. 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 AUTOADAPT and FLOW ADAPT. FLOW ADAPT reduces the need for throttling valves, thus cutting costs on system components. MAGNA3 is the superior choice for a wide range of heating and cooling applications, including:

• Mixing loops
• Heating surfaces
• Air conditioning surfaces
• Ground-source heat pump systems
• Smaller chiller applications.

MAGNA3 is a single-phase pump characterized by having the controller and control display integrated into the control box. The pump also has a built-in differential pressure and temperature sensor. 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 stainless steel, and the stator housing is aluminum. The power electronics are air-cooled. MAGNA3 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. An integrated frequency converter controls the pump speed.

* The manufacturer recommends using the Grundfos 98046408 MI 301 Go Remote for optimal setup and troubleshooting of this pump.
