Q: What is an understanding of the load profile of your application essential for?
A: Pump selection
Correct
Q: What happens to the flow when the NPSH value increases?
A: It increases as well
Correct
Q: What do you have when there’s a cross point between the system’s characteristics and the pump’s performance?
A: The specific duty point
Correct
Q: When selecting a pump for variable flow, what's imperative?
A: Looking for pumps which offer the best efficiency at lower more frequent flow
Correct
Q: Why will pumps with a constant duty point soon be a thing of the past?
A: Beause of the use of variable speed pumps for applications with variable demand
Correct
Q: What does a P2-curve measure?
A: The relation between a pump’s power consumption and flow
