Q

On what type of pump would you find an impeller?

🔍 Key Concepts

• Impeller as a rotating component that throws fluid outward • Difference between dynamic (centrifugal) pumps and positive displacement pumps • Typical internal parts of gear, vane, and piston pumps

💭 Think About

• Which pump type moves liquid mainly by spinning it and using centrifugal force, rather than trapping set volumes of fluid? • In which of these pump types would a disc or wheel with blades or vanes be mounted on a shaft and rotate at high speed? • For each option, picture the internal moving parts: which one clearly uses an impeller, and which use meshing parts or reciprocating motion instead?

✅ Before You Answer

• Be clear on what an impeller looks like: a rotating wheel or disc with curved blades/vanes. • Identify which of the listed pumps are positive displacement pumps that move fixed volumes of fluid each cycle. • Eliminate any pump type whose main moving elements are gears, sliding vanes, or pistons instead of an impeller.
