1: What is the benefit of aligning primary side flow with secondary side flow?
To avoid or minimise the ‘low’ Delta T syndrome
2: What is the key design element in Grundfos Distributed Pumping?
A new kind of intelligent valve
You can find the answer here >
2: What is the key design element in Grundfos Distributed Pumping?
The use of intelligent pumps instead of valves

4: Pump energy savings in a distributed pumping system are around:
54%
5: Why is there in most cases no bypass flow with a distributed pumping system?
Because primary pumps try to match primary flow and secondary flow
5: Why is there in most cases no bypass flow with a distributed pumping system?
The bypass valve is always closed
You can find the answer here >
5: Why is there in most cases no bypass flow with a distributed pumping system?
The system is never over-pumped
You can find the answer here >
6: Why is coil flow always correct in a distributed pumping system?
By using large variable speed-controlled primary pumps
You can find the answer here >
6: Why is coil flow always correct in a distributed pumping system?
Because Magna 3 pump speed is modulated based on terminal unit load
6: Why is coil flow always correct in a distributed pumping system?
Because the system runs with maximum flow at maximum load
