Grundfos Circulator pump MAGNA3 32-100 F

The Grundfos MAGNA3 circulator pump is the ideal choice for almost any building project – old or new. With its
unrivalled energy efficiency, all-encompassing range and built-in communication capabilities, MAGNA3 is ideal 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 pump and motor form an
integral unit without shaft 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.
MAGNA3 model E has Bluetooth, which allows you to connect directly to Grundfos Go app on your smart phone
without any need for a dongle.
The pump includes fieldbus communication via CIM modules as well as analog and digital inputs and configurable
relays.
Control features include AUTOADAPT and FLOWADAPT. FLOWADAPT which 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 and characterised by having the controller and control display integrated in 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-fibre
reinforced, the bearing plate and rotor cladding are made of stainless steel and the stator housing is made of
aluminium. The power electronics are air-cooled.
MAGNA3 incorporates a 4-pole synchronous, permanent-magnet motor (PM motor). This motor type is characterised
by higher efficiency than a conventional asynchronous squirrel-cage motor. The pump speed is controlled by an
integrated frequency converter.
