Grundfos - Magna1 32-100 99221236 Variable Speed Circulator - 180mm - 230V - Cast Iron

With its high energy efficiency, the product complies with the EuP 2015 regulations, ensuring substantial savings on electricity. With its intuitive, user-friendly interface and maintenance-free design, MAGNA1 is the well-suited circulator pump for basic performance needs in applications where basic system control and monitoring are desired.

With this range of circulator pumps, everything from setup to basic control and monitoring are made straightforward. The pump is maintenance-free due to the canned-rotor type design. MAGNA1 offers the possibility of monitoring the pump via the fault relay output. The digital start and stop input remotely controls the pump. The pump communicates wirelessly with the Grundfos GO Remote app. MAGNA1 can work as the main pump in both heating and cooling applications, including:

MAGNA1 is a single-phase pump characterised by the controller and operating panel being integrated in the control box. 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.

The pump 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.

Suitable for: Commercial heating, Commercial air conditioning, District heating, District cooling, Domestic heating, Industrial heating
