Pulsation Dampeners / Pulse Intensification and Dissipation Type

Dampeners that accelerate the velocity of the pressure wave, increasing its amplitude, then destroy the wave by exploding it into a chamber, within which chamber the distance to any reflection point is so great that the amplitude is decreased to an acceptable level. Said amplitude then being decreased still further by the difficulty with which the residual peak can find its way on out down the system. These dampeners are known as the RAM-JET & Discharge Coefficient type. Introduced by our licensor M. Packer in 1979, WaveGuard "RJ"
The primary advantages of this technology, are small size relative to performance. Non reflection of pressure activity back into the system - as occurs with plain "orifice" types. Low pressure drop relative to attenuation performance. Compared to "helmholtz orifice" devices, sometimes called "reactive models", or to foam filled types, the WaveGuard is not only far superior in performance, but also smaller and less expensive. WaveGuard / "RJ" is probably the best all round pulsation dampener type of the nine types offered. Best performance is in the 25 to 500 Hz. range.

Pulsation Dampeners with No Moving Parts

PRESSURE PULSATION DAMPENERS THAT DO NOT ACCUMULATE FLOW. Otherwise known as "no moving parts" dampeners, "bladderless" dampeners, "membrane free" dampeners, "fit and forget" dampeners, and (the "iffy" one) the "foam-filled" type.
