🔍 Key Concepts

• Centrifugal pump operation – how flow is created by spinning the impeller and why it needs liquid at the eye of the impeller • Priming – what it means and why air in the casing affects a centrifugal pump • Difference between conditions that stop all flow at start versus conditions that just reduce efficiency or cause leakage

💭 Think About

• Which of these conditions would prevent the pump from creating any suction at all when first started? • For each choice, ask: would this make the pump move some water poorly, or would it stop delivery completely until another step is done? • Think about what happens if the casing or suction side is full of air instead of water—how does that affect the impeller’s ability to move liquid?

✅ Before You Answer

• Be clear on the definition of priming and what a non‑self‑priming centrifugal pump requires before start-up • Identify which options would mainly cause leakage or reduced capacity, not a total failure to deliver on initial start • Verify which condition specifically relates to air bound or loss of suction at the eye of the impeller
