Example: - Suction pressure too high. Driving the pump, instead of "doing its thing".

You have the hardware already? LDi has the tools.
Certified calibrated signal conditioned transducers.
Real time massive paper rate, oscillograph printers.
GPIB data stream capture laptops, with FFT analysis.
Yes even stethoscopes! Let us identify the heart of the problem, on site.

"Joukowski" velocity jump, excites RV.
For More on this example please see LDi Pub.1 P.7

The answer is simple, as usual its the pipe,
it is stopping one cylinder filling - TOO LONG.

For more on the "manifolding" examples, right, please see Octopussies LDi Pub. 5. P34, 35.

We will survey your pumping system pipe and advise
Where:- 1. They are oversized, 2. Direction changes are causing instability., 3. "Ts" & "Hard 90s" need replacing.
NO =RPM doubled from 1950s design, valves driven off seats by suction column oscillation.
YES = Stop valves from "talking" to each other.
NO WAY = Typical Manifold turns pulse into an "orchestra".
YOU BET = intercepts.

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

PulseGuard Inc., and Ltd. for further information about pulsation dampeners / pulsation dampers. - Pulsation Dampener - Pulsation Dampeners - Pulsation Dampers
PulseGuard für Deutschland - Pulsationsdämpfer and to find large gas bag vessels, jumbo bladders, float separator / big bellows type pipeline shock attenuators and expansion / contraction volume compensators, surge alleviators, and shock alleviators. - Surge Alleviators - Shock Alleviators and for information about energy saving in pumping systems, standby emergency power, safety shutdown systems, hydraulic accumulators, and hydropneumatic accumulators. - Hydraulic Accumulators - Hydropneumatic Accumulators 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 with flow fuses and breather bags
