Question: Which Pumps are used for Grundfos Distributed Pumping

Answer:

Grundfos Distributed Pumping is made possible with our connected pumps that gives optimal and intelligent distribution of chilled water to all terminal units.

For supplying each terminal unit, we utilised our MAGNA3 range as coils pumps. The MAGNA3 is a canned-rotor type, i.e. pump and motor form an integral unit without shaft seal and integrated variable speed drive and IE5 motor giving you the most efficient pump within its' class and it doesn't require maintenance. The MAGNA3 comes with all the needed control algorithms to modulate the chilled water flow as the heat load of the building changes, by using external temperature sensor to maintain constant supply or return air temperature.

For primary pumps we are able to drastically reduce the pumping power rating (kW) since they now only need to circulate the water in the primary side up to the de-coupler. We recommend using our in-line TPE range with IE5 motors and integrated VFD. The advantage of these pumps, are they don't require alignment and are perfectly balanced, giving the shaft-seal a much better lifetime.

Additional information:

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.
