Question 1 of 27070

Of the choices provided, which type of pump does the suction force principle primarily apply to?

🔍 Key Concepts

• Suction force and how it is created in different pump designs • Difference between dynamic (rotodynamic) pumps and positive displacement pumps • How pressure is lowered at the pump inlet to draw liquid up from a sump or bilge

💭 Think About

• Think about which pump type traps a volume of liquid and physically pulls it along the suction line versus which types rely mainly on high-speed rotation to move liquid. • Consider which design depends most on creating a partial vacuum at the inlet to lift fluid up from below the pump. • Ask yourself: in which pump would air leaks on the suction side most quickly destroy its ability to lift fluid using suction?

✅ Before You Answer

• Review which pump types are positive displacement versus dynamic. • Check which pump type is commonly used as a bilge or cargo stripping pump because of its strong suction lift capability. • Verify which designs (jet, centrifugal, propeller, reciprocating) can still move fluid even when suction lift is poor or minimal.
