Sorry. You did not pass the 69 - The Grundfos Distributed Pumping Course test this time
Achieved badges:
How would you rate this course?
1: 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
1: 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 >
1: 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 >
2: 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 >
2: Why is coil flow always correct in a distributed pumping system?
Because Magna 3 pump speed is modulated based on terminal unit load
2: Why is coil flow always correct in a distributed pumping system?
Because the system runs with maximum flow at maximum load
