4 rollers VS 8 rollers Peristaltic pump head pulsation

[@dhavalprajapati5778]

I like the pump..can you please tell me the pump name and model so that I can buy it.

[@R1M337]

where did u buy the 8rollers?

[@jrperrotta]

The conclusion with your example is the pulsation is the same. But why confuse the viewer with all of this useless added hose? Your presentation is false as the house layout disappears off the screen and the looped hoses intentionally confuse the viewer

[@MIKESF2BLS]

why did you have them spin at different speeds.... that makes no sense

[@dvdny]

Because pumping rate goes down with more rollers.

@@dvdny that's nonsense

@@Kawka1122 This video proves that 8 rollers puts out less than 4, all other parameters being equal. Perhaps the question I answered was incorrect, as they're both running at the same speed (about 35 RPM).
