What temperature range can pumps tolerate exposure to without damage?

The correct answer indicates that pumps can tolerate exposure to temperatures ranging from -40 °F to +140 °F without sustaining damage. This range is significant because it encompasses both extreme cold and heat, allowing pumps to function effectively in a variety of environmental conditions.

Pumps are critical components in many systems, including marine and automotive applications, where they may be exposed to harsh weather conditions. The ability to operate within this wide temperature range ensures the reliability and durability of pumps in real-world applications. Materials used in manufacturing pumps, such as plastics, metals, and elastomers, are engineered to withstand these temperatures, minimizing the risk of failure due to thermal stress.

In contrast, the other options set narrower temperature limits, which could lead to potential risks when pumps are exposed to temperatures outside those ranges. Selecting the broadest acceptable range shows the versatility of pump design and its ability to maintain functionality across varied climates.
