It is important to design pump systems to prevent water hammer in order to avoid potentially devastating conse-quences, such as damage to components and equipment and risks to how to prevent water hammer re-quires a fundamental understanding of fluid prop-erties, governing equations and the design and op-eration of pipe systems, valves , pumps and pump stations.
