What is the primary reason to avoid letting pumps run dry?

Avoiding letting pumps run dry is primarily important to prevent damage to the pumps. When a pump operates without any fluid, it can lead to overheating due to the friction between moving parts, which results in excessive wear or even complete failure of the pump. The absence of fluid means there is no lubrication, which is essential for the pump's components to function smoothly. Over time, this can cause seals to fail, bearings to wear out prematurely, and the overall life expectancy of the pump to be drastically reduced.

While enhancing water quality, increasing system efficiency, and maintaining water pressure are important considerations in pump operation, they are secondary to the immediate mechanical integrity of the pump itself. Running a pump dry poses a direct risk to its operational effectiveness and longevity, making it crucial to ensure that pumps are always supplied with the necessary fluid for safe and efficient operation.
