Preventing Water Hammer from Damaging Pumps and Pipes ...

When it collides with the valve or pump, a severe hammer can occur. The closure of non-return valves can also cause water hammer. Some systems are very prone to this, and the use of a simple swing check valve can give severe water hammer. Some companies manufacture non-return valves which minimise water hammer caused by their operation.

What is Water Hammer? | Electrical4U

Water Hammer in Power Plants. Water hammer occurs when water, accelerated by steam pressure or a low-pressure void, is suddenly stopped by impact on a valve or fitting, such as bend or tee, or on a pipe surface. Water velocities can be much higher than the normal steam velocity in the pipe, especially when the water hammer is occurring at startup.
