The most likely reason pumps are primed is to?

• A. Wet The Packing
• B. Start The Flow
• C. Keep The Pump Lubricated
• D. Protect The Bearing

Answer: (B)

Priming a pump means filling the pump and its suction line with liquid and removing any air so the pump can develop suction and draw the wastewater into the impeller. With a clear liquid column, the impeller can impart energy to the fluid and start flow through the discharge line. If air remains in the suction line, the pump can’t create the necessary vacuum to lift and move the liquid, so the prime is lost and no flow results. So priming is done to start the flow. The other options relate to sealing, lubrication, or bearing protection, which are separate maintenance concerns rather than the reason for priming.
