🔍 Key Concepts

• Pump impeller wearing rings function and why correct fit/alignment matters • What pressing a ring onto a hub can do to trueness (runout) and balance • Differences between checking alignment/trueness, balancing, and in‑service inspection

💭 Think About

• Which action is needed immediately after pressing the new wearing rings on the hub, before the pump is put back in service? • How can you detect if the pressing operation has distorted the ring or caused it to be out of round or off‑center? • Would you wait for the pump to run an hour, or should you verify something about the mechanical fit first while it’s still on the bench?

✅ Before You Answer

• Focus on what you can check on the shop floor right after installation, before running the pump • Ask whether dynamic balancing is always required after replacing just wearing rings, or only when there is evidence of imbalance • Think about how machinists use centers and dial indicators to confirm that circular surfaces run true and concentric with the shaft
