🔍 Key Concepts

• Difference between centrifugal and positive displacement pumps • What happens to pressure and flow when a discharge valve is closed • Which pump types can be deadheaded (run against a closed discharge) without immediate damage

💭 Think About

• Think about which pump type depends on continuous flow of liquid for cooling and which one traps and forces a fixed volume of liquid each revolution • Ask yourself: If the discharge is blocked, which pump will quickly build very high pressure inside the casing or lines? • Consider which pump type, when flow is stopped, will mostly just spin the liquid without creating dangerous pressure

✅ Before You Answer

• Identify which of the listed pumps are positive displacement types • Identify which of the listed pumps are non‑positive displacement (dynamic) types • Verify which category of pump is most likely to suffer mechanical damage when operated with the discharge valve shut
