🔍 Key Concepts

• Centrifugal pump internal clearances and how they affect leakage and pressure • The purpose and location of wear rings on a pump impeller and casing • Difference between parts that transmit power (shafts, couplings) and parts that control hydraulic performance

💭 Think About

• Which pair of components, if the gap between them increases, would allow more fluid to leak from the high‑pressure side back to the suction side? • Which listed parts actually form the main pressure boundary where the impeller discharges into the casing? • Which parts are mainly for alignment or power transmission, and which are designed as sacrificial, replaceable parts to maintain pump efficiency?

✅ Before You Answer

• Identify which parts are hydraulic sealing surfaces versus purely mechanical connection parts • Recall that excessive internal recirculation in a centrifugal pump lowers discharge pressure and efficiency • Verify which component(s) in the choices are specifically designed to be replaceable to restore design clearance in a worn pump
