🔍 Key Concepts

• Centrifugal pump priming and why a positive suction head matters • What it means for a pump to become air bound • Correct sequence of actions: protect the pump, restore liquid flow, then adjust components

💭 Think About

• When a centrifugal pump is air bound, what is actually inside the casing and impeller instead of liquid, and how does that affect pumping ability? • Which action would safely restore a continuous column of liquid to the impeller with the least risk of damage or overload? • Would changing discharge conditions or packing fix the problem inside the casing, or do you need to deal with the trapped air first?

✅ Before You Answer

• Identify which option directly addresses removing trapped air from the pump casing • Confirm which action should be done before changing discharge valve position or adjusting packing • Consider standard pump start-up and recovery from loss of prime procedures in marine engineering practice
