Description
The Grundfos MAGNA3 circulator pump is ideal for almost any building project – old or new. With its unrivaled energy
efficiency, all-encompassing range, and built-in communication capabilities, MAGNA3 is suitable for engineers and specifiers looking to
create high-performance heating and cooling systems.
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 with the controller and control display integrated into the control box. The
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 more efficient than a conventional asynchronous squirrel-cage motor. An integrated frequency converter controls the pump speed.
