🔍 Key Concepts

• Centrifugal pump vs reciprocating pump basic design differences • How pump type affects flow rate, size/weight, and cost • Typical use of each type in cargo handling on ships

💭 Think About

• Think about which pump design is better suited for moving large volumes of liquid continuously, such as cargo oil or ballast water. • Consider the mechanical complexity of a reciprocating pump (pistons, valves, rods) versus a centrifugal pump (impeller in a casing). How might that affect cost and size? • Ask yourself: on most modern tankers, which type of pump is commonly used for cargo discharge and why?

✅ Before You Answer

• For each option, ask: Is this statement generally true of centrifugal pumps when compared to reciprocating pumps? • Be careful with words like "more", "less", or "smaller"—they must be correct in a typical marine application, not just in a special case. • Only choose "All of the above" if you are confident that every single individual statement (A, B, and C) is correct.
