We have gathered frequently asked questions and their answers in one place. See the most frequently asked questions below or go to the Grundfos FAQ for a complete list of answers to your questions.
Does a distributed pumping solution require hydraulic balancing?
No. Because we use small circulators as coil pumps to supply chilled water to each terminal unit (ie. Air handling unit), your entire building will be perfectly balanced at any load.
This also simplifies the design phase, as it is no longer necessary to determine the critical pressure point / index loop when doing the HVAC design. With distributed pumping, your whole system becomes decoupled and each pump is sized to deliver just the right flow.
How reliant is a distributed pumping system compared to a conventional system?
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 realeased in 2012 and more than 1 millions 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....
