How would you rate this course?
1: What is the key design element in Grundfos Distributed Pumping?
A new kind of intelligent valve
You can find the answer here >
1: What is the key design element in Grundfos Distributed Pumping?
The use of intelligent pumps instead of valves
1: What is the key design element in Grundfos Distributed Pumping?
Making bypass lines obsolete
You can find the answer here >
2: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
You don’t need non-return valves – intelligent pumps make all valves redundanteed
You can find the answer here >
2: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
To avoid backflow in case the AHU unit is out of operation
2: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
You only need non-return valves for proportional pressure installations

3: Pump energy savings in a distributed pumping system are around:
54%
4: 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
4: Why is there in most cases no bypass flow with a distributed pumping system?
The bypass valve is always closed
