🔍 Key Concepts

• centrifugal pump priming and the need to remove air from the casing • difference between static (positive) suction head and negative suction (lift) • how air is vented or primed out of a pump casing before starting

💭 Think About

• Which option directly provides a path for trapped air at the highest point of the pump casing to be released? • Which options describe system conditions (like suction head) rather than a specific fitting or device on the pump itself? • Think about what must be done to a completely dry centrifugal pump before it can move liquid effectively.

✅ Before You Answer

• Identify which choice is an actual fitting or component installed on the pump casing, not a system condition. • Consider where air naturally collects in a volute casing and what you’d need there to get it out. • Verify which choice specifically allows you to open something and bleed air, not just ensure a flooded suction.
