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

5: Why is there in most cases no bypass flow with a distributed pumping system?
The system is never over-pumped

6: How does distributed pumping ensure minimum flow over each chiller?
By having a differential pressure sensor installed across each chiller
6: How does distributed pumping ensure minimum flow over each chiller?
By running with maximum flow at maximum load
