Test results
Congratulations. You have passed the test and completed the 69 - The Grundfos Distributed Pumping Course
Achieved badges:
Q: Why is there in most cases no bypass flow with a distributed pumping system?
A: Because primary pumps try to match primary flow and secondary flow
Q: Why is there in most cases no bypass flow with a distributed pumping system?
A: The bypass valve is always closed
Q: Why is there in most cases no bypass flow with a distributed pumping system?
A: The system is never over-pumped
Q: With a single dedicated pump for each terminal unit, which control mode is used?
A: Proportional pressure
Q: With a single dedicated pump for each terminal unit, which control mode is used?
A: Proportional pressure or constant temperature – doesn’t matter
Q: With a single dedicated pump for each terminal unit, which control mode is used?
A: Constant temperature

Q: How does distributed pumping ensure minimum flow over each chiller?
A: By having a differential pressure sensor installed across each chiller
Q: How does distributed pumping ensure minimum flow over each chiller?
A: By running with maximum flow at maximum load
Q: How does distributed pumping ensure minimum flow over each chiller?
A: By ensuring the primary pump is larger than in a conventional system
