What happens when a centrifuge pump loses prime?

The pump starts moving air
The pump stops moving liquid
The pump increases pressure
The pump continues to operate normally

The correct answer is: The pump stops moving liquid

When a centrifuge pump loses prime, it primarily affects its ability to move liquid effectively. Losing prime means that the pump is no longer filled with liquid; instead, it may begin to move air or vapor, which can lead to various operational issues. In this situation, since the pump relies on the presence of liquid to create pressure and generate flow, it will stop moving liquid. Maintaining prime is essential for a centrifuge pump to function properly, as it creates the necessary suction to draw in fluid. Without this, the pump cannot perform its intended function, which is to continuously move wastewater through the system. The correct understanding of this behavior is critical for effective operation and management of pump systems in wastewater treatment facilities.
