No Moving Parts Dampeners Since 1965.
HOW THEY WORK
Why they are so huge and expensive.

Ball-Pack Diffusion (Pulsation Diffusers). Spreading the time base, makes transient amplitudes shrink.
Pulsation Dampener / Acoustic Pulsation Snubber Part Nbrs. WaG/Cer
Pressure transients with rise rate in excess of 100,000 psi per second are very common. For example, 50 psi and greater spikes at 1000 Hz. are a rise rate of at least 100,000 psi/sec. Pressure travels in an average liquid at a mile a second, so it will take 1/1760 seconds to pass through a 36" WaveGuard. However, some of the transient will travel three times the distance around the balls, and some will go a hundred different distanced paths through them. The parts of the transient will arrive at the other end at different times.
This time lag, spreading of the base time, reduces the height of the transient to near nothing. The volume of liquid between the balls, approx. 30% of the total cylinder volume, has a mass deadening effect and its compressibility also helps.
Three things have caused the disappearance of the high frequency transient disturbances, time lag has spread the base reducing the height, mass has deadened, and the modulus of compressibility has absorbed.
WAVEGUARDS WITH THE CERAMIC BALL PACK ARE FOR HIGH FREQUENCY ATTENUATION.

CONCLUSION:- By undersanding the little Liquid Dynamics, you can dispense with moving parts dampeners , but it will take alot of space and money
