Grundfos MAGNA circulator pumps are used in commercial buildings for air conditioning, heating and water supply applications.
Grundfos MAGNA circulator pumps are used in commercial buildings such as schools, hospitals and office buildings for circulating potable hot water, hot water in heating systems, and cold water in small-sized air conditioning systems.
The MAGNA family is characterised by integrated intelligent frequency converters and permanent magnet motors. This allows variable speed operation that corresponds to the variable energy demands of the system.
Grundfos MAGNA pumps feature glandless constructions. The pumped media is circulated in the system is also used to cool and lubricate the motor and rotating parts during operation.
The MAGNA family offers the full range of product variants, comprising 28 different models, with flow ranging from 1 - 39m3/h.

Grundfos MAGNA pumps save energy by adjusting performance to demand. According to the international agreed load profile for a circulator, a pump performs to its maximum only 6% of the time. It is therefore beneficial that the pump reduces it speed (rpm) the remainder of the time, thereby saving energy and money.
Each MAGNA pump automatically adjusts its output to the current conditions. This ensures that energy consumption is always kept to a minimum.
By automatically controlling its own speed, the pump will continuously regulate the pressure (head), so that it is optimally adapted to the speed of the water (flow).
Grundfos MAGNA pumps feature the unique AUTOADAPT function. It works to continuously adapt energy consumption by adapting to the system in which it is installed.
