🔍 Key Concepts

• Pump cavitation occurs when the pump suction side is starved or air/vapor enters instead of solid liquid. • In a hydraulic reservoir, components like breathers, strainers, and fittings each affect either contamination control, venting, or suction flow. • Identify which labeled part is on or near the suction line to the pump, and which parts mainly deal with cleanliness or level indication.

💭 Think About

• Which labeled component, if it failed or were mishandled, would most directly cause restricted flow or air leakage on the suction side of the pump? • Looking at the illustration, which part is clearly an internal suction strainer, and which are external fittings or caps? How would each problem listed in the choices change the pump’s inlet conditions? • For each option, ask: does this mainly introduce dirt, change tank venting, leak air on suction, or simply remove filtration? Which of those conditions is most likely to cause cavitation in the short term?

✅ Before You Answer

• Verify which label corresponds to the suction strainer and which to breather/filler caps or simple fasteners. • Decide which failure would most likely reduce liquid flow or allow air into the suction line, not just add contamination. • Make sure you can explain, in your own words, why each wrong choice would NOT immediately cause cavitation but might cause a different problem (like contamination or minor leakage).
