What is the purpose of a flexible connector used on pump piping?

A flexible connector in pump piping serves primarily to accommodate expansion and vibration. When pumps operate, they generate movement and can often experience thermal expansion due to changes in temperature. A flexible connector allows for this expansion to occur without causing stress or damage to the piping system. Additionally, the movement and vibrations produced by pumps, especially when in operation, can lead to misalignments or wear on rigid connections. The use of flexible connectors helps absorb these vibrations, reducing the risk of wear and loosening over time.

While flexible connectors can influence flow rates to some extent, their primary function is not to increase flow speed, nor are they primarily designed to reduce noise output or simplify installation. Although the inclusion of flexible connectors can contribute to a smoother installation process and potentially lower noise levels by dampening vibration transmission, these are secondary benefits compared to their main role of managing expansion and vibration.
