The MAGNA/UPE pumps make up a broad range of small, medium and large circulator pumps fitted with communication equipment and motors with electronic speed control based on permanent magnet (PM) and compact stator motor technology.

The MAGNA is an innovative member of the Grundfos family of high-quality circulator pumps.

With a MAGNA, you can stop worrying about complicated pump settings. Simply install the pump and leave it on the factory setting, AUTOADAPT (MAGNA only).

The MAGNA will automatically analyse the heating system, find the optimum setting and then continuously adjust its operation to changes in demand. The result is optimum comfort and minimum energy consumption. In addition, MAGNA pumps are extremely flexible and reliable, and have low noise levels, long life and no maintenance requirements. They are fitted with IR communication and can offer external control and monitoring via expansion modules.

Applications

GRUNDFOS MAGNA/UPE pumps are designed for circulating liquids in heating systems in blocks of flats, schools, hospitals, hotels, industry, etc.

These pumps, which have stainless steel pump housings, can also be used in domestic hot-water systems. GRUNDFOS MAGNA pumps are suitable for the following:

• Systems with constant or varying flows where it is desirable to optimise the pump duty point
• Systems with varying flow-pipe temperatures
• Systems where night setback is required.
