Central heating pumpGrundfoss Magna3

Grundfos MAGNA3 is a maintenance-free, highly energy-efficient circulator pump for versatile heating and cooling applications, such as mixing loops, heating/cooling surfaces, and geothermal systems. The canned rotor design lubricates bearings with pumped liquid, requiring no external motor protection. Integrated control functions like AutoAdapt and FlowAdapt reduce system part needs and costs. Supports extensive communication (CIM modules, analog/digital inputs, relays) and Grundfos GO Remote app. Available in cast iron or stainless steel, with a powerful four-pole PM synchronous motor and variable speed drive. MAGNA3 offers features like thermal energy monitoring, automatic night setback, and intuitive control display.
