🔍 Key Concepts

• Differences between centrifugal and reciprocating pumps • Typical advantages of centrifugal pumps used for cargo handling • What it means when a pump requires priming, especially at low suction heads or for stripping operations

💭 Think About

• Which options describe features that make centrifugal pumps popular for high-volume cargo transfer on tankers? • Think about the stripping phase: when the tank level is very low, does a centrifugal pump work better or worse than a reciprocating pump? • Which choice sounds more like a disadvantage or limitation, rather than a benefit, in normal cargo operations?

✅ Before You Answer

• Identify which statements are commonly cited as advantages of centrifugal pumps in training manuals and pump comparisons. • Consider whether having to prime a pump is generally seen as an extra step (more complexity) or as a benefit. • Check which feature would make centrifugal pumps more attractive than reciprocating pumps for large-scale cargo operations (flow rate, size, and cost).
