🔍 Key Concepts

• pump symbols in piping diagrams – notice the shape inside the circle at item "5" • difference between dynamic pumps (like centrifugal) and positive displacement pumps • how impeller/vane blades are usually drawn in schematic symbols

💭 Think About

• Look closely at the internal marking of symbol 5. Does it show a flexible element, reciprocating part, or rotating blades? • Which of the answer choices is a broad category and which are specific types that belong to that category? • In this type of cooling/recirculation system, what kind of pump is most commonly used for continuous, steady flow?

✅ Before You Answer

• Compare the symbol at 5 with standard symbols for centrifugal vs. positive displacement pumps in your reference materials or inside the exam booklet. • Ask yourself whether diaphragm and rotating vane pumps are usually shown with a simple impeller-like curve or with more detailed internal outlines. • Verify whether the system shown (feeding multiple consumers at 4) would typically use a constant-flow dynamic pump or a displacement-type pump.
