The Effects of Water Hammer And Pulsations The Effects of Water Hammer And Pulsations. Quick closing valves, positive displacement pumps, and vertical pipe runs can create damaging pressure spikes, leading to blown diaphragms, seals and gaskets also destroyed meters and gauges. Liquid for all practical purposes is not compressible, any energy that is applied to it is instantly transmitted. This energy becomes dynamic in nature when a force such as quick closing valve or a pump applies velocity to the fluid. Importance of Using...

What is Steam Hammer and How to Eliminate It If your heating equipment is violently shaking, then it is a concern that needs to be addressed. It is not only dangerous, but it also can be an expensive maintenance problem. Externally modulated technologies such as heat exchangers or unsophisticated forms of direct steam injection, such as spargers, can cause steam hammer. Learn more about external vs. internal modulation, direct and indirect heating, and why direct steam injection works!

Blacoh Fluid Control, Inc.
Solving water hammer in diesel transfer and inconsistent transfer pressure. * Extremely long transfer times (6 -8 hours for a 30% fill). Root Causes Identified: 1. Pump suction pressure significantly exceeded recommended limits, producing severe water hammer effects and subjecting PTFE diaphragms to damaging pressure spikes. 2. Process air regulator pressure was set too high, further increasing pressure peaks and accelerating failures. 3. The original pump design lacked necessary stabilizing accessories to control pulsation and protect downstream... (read more)Browse Pulsation Dampeners Datasheets for Blacoh Fluid Control, Inc. -

Got Water Hammer? Download DFT's eBook DFT (R) Inc's engineers have been working with professionals in a range of industries for over 80 years, helping to identify and resolve water hammer's underlying causes. Water hammer and reverse flow can seriously damage pipelines, pipe joints gaskets, pumps, and all the other components of a fluid flow system (flow meters, pressure gauges, etc.). The pressure spikes can easily exceed five to ten times the system's working pressure; upon impact, thereby placing a great deal of stress... (read more)Browse Check Valves Datasheets for DFT Inc. -

Watch DFT's Webinar: Water Hammer What Is It? Water hammer is a relatively common problem that is often only briefly touched upon in engineering school curriculums. As a result, it is common that the cause and effect of water hammer are not taken into account when designing industrial or residential systems. Often engineers do not realize the extent of damage it can cause in piping systems. At DFT (R), our support teams are frequently called into "course-correct" after the consequences of water hammer have already occurred. To help you...
