Pulsation Dampers for Flow & Pressure by PulseGuard

Know How To Connect It Before You Select It

This "Y,T" piece replaces the T's that you would have to purchase and weld into your system. Its top face is an "O" ring flange. Dampeners are serviced by simply removing the four bolts. If you wish to be able to run your system without the damper in place we provide flow caps to go in place of the damper so that your system may continue to be used without the damper in place.

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 dampers adress pressure amplitude at frequency. The characteristics of a pressure 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.
