Test results
Congratulations. You have passed the test and completed the 69 - The Grundfos Distributed Pumping Course
Achieved badges:
Q: What is the benefit of aligning primary side flow with secondary side flow?
A: To ensure distributed pumps never miss water on the suction side
Q: What is the benefit of aligning primary side flow with secondary side flow?
A: To avoid increasing pressure in the bypass pipe
Q: What is the benefit of aligning primary side flow with secondary side flow?
A: To avoid or minimise the ‘low’ Delta T syndrome
Q: What is the key design element in Grundfos Distributed Pumping?
A: A new kind of intelligent valve
Q: What is the key design element in Grundfos Distributed Pumping?
A: The use of intelligent pumps instead of valves
Q: What is the key design element in Grundfos Distributed Pumping?
A: Making bypass lines obsolete
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: How much flow is required to achieve almost 80 % of the capacity?
A: 50%
Q: How much flow is required to achieve almost 80 % of the capacity?
A: 30%
Q: How much flow is required to achieve almost 80 % of the capacity?
A: 80%
Q: With a Distributed Pumping system, does commissioning and balancing
A: Take longer
Q: With a Distributed Pumping system, does commissioning and balancing
A: Become obsolete
Q: With a Distributed Pumping system, does commissioning and balancing
A: Is done quickly and easily
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
