🔍 Key Concepts

• Centrifugal pump performance curves (relationship between speed, flow, and pressure) • Difference between self-priming and needing to be flooded/suction head • Effect of pump speed and discharge valve position on pressure and flow

💭 Think About

• Think about how a centrifugal pump actually moves liquid: is it trapping fixed volumes, or throwing liquid outward with an impeller? How would that affect priming? • If the impeller spins more slowly, what happens to the energy given to the liquid and, therefore, to the discharge pressure? • When you open a discharge valve wider on a centrifugal pump, does the pump create more pressure, or does the system allow more flow for a given pressure?

✅ Before You Answer

• Be clear on whether all centrifugal pumps can lift liquid without being flooded on the suction side (self-priming or not). • Recall that for centrifugal pumps, head (pressure) is proportional to the square of speed; what does that imply when speed is decreased? • Consider whether changing the discharge valve position mainly changes flow rate, pressure, or both—and in which direction for a centrifugal pump.
