What action should be taken if the pump runs dry?

When a pump runs dry, the most critical action is to shut down the pump immediately. This is essential because running a pump without water can lead to severe damage due to overheating and mechanical failure. Pumps are designed to operate with fluid to provide lubrication and cooling. Without water, the impeller will continue to spin and generate heat, which can cause the pump components to warp, seize, or even fail catastrophically.

Shutting down the pump allows for an assessment of the situation and prevents any further damage that might occur from continued operation. It's also vital for ensuring the safety of the personnel and equipment involved. Effective response actions after shutting down may include checking intake lines for obstructions, verifying water sources, or conducting maintenance checks, but the immediate priority is to halt operation to protect the pump's integrity.
