Flow Control / Pressure Dampeners - Why a "pressure damper"? Because pressure dampers are used to dampen pulsation. Pulsation is measured and seen as a repeated chenge in pressure. Pressure pulastion dampers adress pressure amplitude at frequency. The characteristics of a pulsation damper have to be designed to respond to the height and fall of pressure at the frequency of the change. A flow through, in and out, pressure damper intercepts the pressure transients so it can respond to its dampening with maximum efficiency and minimum cost.

Flow fluctuation suppression devices aka for "pulsing systems" may be called reactive or non-reactive passive in pressure response. Intrinsically when a proportion of head change due to mass acceleration is prevented from occurring by the application of the softness, or cushion, of a liquid accumulator there is still a residual fluctuation. The head change or pressure change that is still residual travels at 1400 meters per second away from the pump, until it meets a point of reflection. Where the distance to the reflection point is say 700 meters, the wave will return in 1 second. This pressure spike (liquid force) will impose a system response frequency of one hertz on the piping. To also address transient and spikes as detailed above, along with the softening effect of accumulators a PulseGuard dual purpose design will be essential to your satisfaction.

(1) Pulsation dampeners for peristaltic and hose pumps handle sludge and slurry with a tubular bladder, straight trough flow flow ensures no blockage from solid particulate.
Liquid inside the bladder chemical metering compatibility saves the need for special metal dampner body materials.
PTFE diaphragm dampeners match high pressure diaphragm pumps, with double layer "sandwich" diaphragms , and secondary containment sealing options.
Stainless housings containing gas "bladders" for dampening pressures and flows through 30.000 psi (2000 bar)
