If you have a pipeline or pump user problem which requires pulsation analysis, diagnostics, or prediction by software:
The definitions of many problems can be found at


Liquid Dynamics provides pipeline and pump user problem analysis, diagnostics, and prediction by software. For water hammer and shock solutions pulsation dampening and shock alleviating devices can be obtained from our associate websites PulseGuard and ShockGuard.


For Hardware see our associate websites: and for further information about pulsation dampeners and pumping systems. and to find large gas bag vessels, jumbo bladders, float separator and big bellows type pipeline shock attenuators and expansion / contraction volume compensators. for more about pulse dampers in pumping systems and water hammer.
Water Hammer  and for more on water hammer, pump start up surge, shut down back flow, & valve closure hammer. and for information about energy saving in pumping systems, standby emergency power, and safety shutdown systems. for a quick view of how each different type of pulse dampener is matched to a pump installation. Pumps make flow, system resistance to flow is pressure, systems make pressure and pressure pulsation. to find protection against excess flow. Guard against toxic spills when pipes burst, guard against gushers and fluid loss when hoses split, Flow-Guard guards against excess flow floods.
