🔍 Key Concepts

• Air-bound centrifugal pump – what it means and where the air collects • Internal shape of a volute casing and where the highest point is • Difference between venting air and priming from suction side

💭 Think About

• On a horizontal centrifugal pump, where is the most likely place that trapped air will rise and collect? • Which location would allow you to release air without losing the pump’s prime or draining the system? • Which choice is specifically part of the pump casing itself, not the external piping?

✅ Before You Answer

• Identify the highest point of the pump casing when installed horizontally • Distinguish between piping (suction/discharge) and the actual pump body/casing • Ask: which point would a vent plug or cock most commonly be installed for removing air?
