🔍 Key Concepts

• Effect of increased wear ring clearance on centrifugal pump efficiency • Relationship between internal recirculation/leakage and pump capacity/pressure • How pump condition affects vibration and lift (suction performance)

💭 Think About

• If more liquid can leak back through the enlarged clearance between impeller and casing, what happens to the useful flow going out the discharge? • How would increased internal leakage inside the pump affect the pressure the pump can develop at a given speed? • Would worn wear rings generally make the pump operate more smoothly, or less efficiently?

✅ Before You Answer

• Review the definition and function of a wear ring in a centrifugal pump (what does it seal between?) • Think about whether maximum clearance would improve or reduce volumetric efficiency • Check which options are consistent with a pump becoming less efficient due to internal recirculation
