Canned-rotor type of circulates have been manufactured by Grundfos since 1959 and integrated speed drives was introduced in 1991, so the design is incredibly reliable and well tested. The current version of MAGNA3 was released in 2012 and more than 1 million units have been sold worldwide for mixed applications.
The expected lifetime of a MAGNA3 is 10 years, but the pump can easily operate longer than this, and is more than able to match the reliance of any type of control valve. Furthermore, if connected to a Building Management System (BMS), it will be able to detect any warnings or alarms on any of the pumps, which ensures the facility management can respond as needed.
Distributed Pumping solutions replace larger centralised pumps and energy-consuming balancing and control valves with smaller intelligent pumps placed on each floor of the building. The result is substantial energy savings and a more comfortable indoor climate.
