Priming is defined as which process?

• A. Filling the pump with liquid and evacuating all gases
• B. Increasing pump speed
• C. Venting the discharge line
• D. Balancing flow and head

Answer: (A)

Priming means preparing the pump for operation by filling the pump and its suction line with liquid and removing trapped air so there’s a continuous column of liquid to be moved. This removes air pockets that would prevent the pump from developing suction and could cause cavitation, allowing the pump to start and deliver flow. The other actions change how the pump runs or the system’s balance after it’s primed, but they don’t accomplish the essential step of getting liquid into the pump and expelling gases.
