LDi - Water Hammer and Shock Analysis, Diagnostics, and Prediction by Software.

The Flexorber

The Flexorber is a mass deceleration and acceleration pressure fluctuation preventor. It can be mounted in any position, and is usually mounted right next to the suction or discharge check valve on the pump to minimise the mass being jerked into motion, and hence preventing shock and oscillation. By removing these two highest amplitude and frequency forms of pulsation, instrumentation and automation becomes possible.

Flexorbers prevent pipe fatigue from pipe resonance caused by

fast safety valve closure
back pressure valve modulation
system check valve instability
sudden liquid mass accelerations

They have a large unobstructed entry port, eliminating any inlet pressure drop which could cause the system to pulsate. There is a resistance in the through-flow and discharge sections of the unit, causing high frequency oscillations which force the membrane to respond.

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.com.

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.
