Thanks for the advice Jim,
I´m actually just building a report on those three brands and their stacked disk designs which are recomended for both noise reduction and cavitation =)(they do have many more designs but it´s tortuous flow path that I´m interested in). More like a side by side...
Im doing some research on these particular brands regarding their stacked disk laberynth design to control excesive noise and cavitation mainly in power generation applications and oil industry.
It would be quite helpful if you guys could share experiences (good or bad) when working with these...
