🔍 Key Concepts

• Identify what type of pump is shown (look at the many small radial vanes and the off‑center inner rotor). • Recall what a liquid‑ring / regenerative type pump is typically used for on ships: moving liquids or handling vapors/gases? • Think about whether such pumps need a sealing liquid to work and what kind of fluids they handle best (low vs high viscosity).

💭 Think About

• From the geometry, does this look like a positive‑displacement pump for thick oil, or a special pump that creates suction for air/vapor systems? • If the pump needs a liquid ring around the rotor, what would happen if there were no sealing liquid present—could it still operate? • Compare what you know about pumps for heavy fuel oil with pumps used for vacuum or gas‑handling: which one matches this construction?

✅ Before You Answer

• Decide whether this pump’s normal duty on board is to move liquids under pressure or to create vacuum by moving gases/vapor. • Consider if a sealing liquid is essential to form a ring and seal the spaces between the vanes and the casing. • Think about whether pumps for high‑viscosity oils usually have this many thin, closely‑spaced blades, or a different, more robust impeller/rotor design.
