🔍 Key Concepts

• Positive displacement pumps vs dynamic pumps • How reciprocating and rotary pumps move fluid compared to centrifugal pumps • Meaning of self-priming and why air in the suction line matters

💭 Think About

• Think about which pump type can move both liquid and air effectively, and which one relies on being completely filled with liquid to work properly • Consider what happens inside each pump if the suction line is full of air instead of water • Ask yourself: which type of pump will just spin or move without developing suction if there is no liquid inside?

✅ Before You Answer

• Identify which of the listed pumps are positive displacement (they trap and push a fixed volume) • Identify which listed pump is a centrifugal/dynamic pump (relies on velocity and centrifugal force) • Verify which type is generally self-priming and which type must be flooded with liquid before starting
