If you starved any sandpiper of air flow it would reduce the frequency the pump cycles and result in a gentler flow. Which is why I was saying it seems like your pump just has more displacement.
Was that video showing 100 GPM?
It seems like your main goal when engineering this pump was to reduce the velocity and turbulence of the flow. High displacement and low cycle would do just that.
Iām not saying your product is garbage by the way.
Iād really like to see those Boba balls at 100 gpm.
It does look like a really nice AODD
This is correct. If you run any pump slower the flow will be less turbulent. This is done by feeding the exchanger a lower PSI. The pump in the video was running almost as slow as possible. So the displacement is very important so you donāt have to run your pump fast to generate the flowrate you may need.
The point was to reduce shear and eliminate areas where trichomes could be damaged. For example, where the diaphragm touches the pump wall. Many other things were modified as well. Check the video out, we go into it in detail.
To be fair, the boba balls should be fine at 100 GPM. I suspect when @raghanded does his test, the balls will get damaged at the ball seat and cage, then crushed by the diaphragm, and then again cut up on the second ball/cage. It will not be an apples-to-apples comparison and of course, some balls will make it out ok.
Sorry I didnāt see the numbers on standard pumps vs this new one. If the selling point is that at scale it saves a fraction of a percentage, make that clearly stated and people can figure out the ROI and go from there.
I donāt doubt it - but thatās definitely not an apples-to-apples comparison to trichomes either lol
No, the point is that I donāt know how to test that. Any ideas to get statistically significant data from a method?
I was just writing that @raghanded Boba test wonāt be āapples to applesā lol.
Because the diameter of his inlet is so much smaller, heās gonna be feeding that pump a different ratio of Boba:water than your pump did.
May be more comparable when dealing with actual trichomes
Bro what the hell is wrong with you? You canāt just assume that was a girl in the promo video and later on you canāt assume it was a guy. Iām not sure exactly which phobia it is but Iām sure itās some sort of phobia by todayās standard.
run the same material through different diaphragm pumps and post pictures of the trichomes under microscopeā¦ shouldnāt be that hard. Repeat the tests 10x to average out variances.
Are you going to send free pumps to people to teach you how to gather the data to validate your product? Or pay them?
Totally agree. It was more for show than anything. Itās difficult to test this out except on CFD simulations by changing points of shear.
Diaphragm pumps are low shear, you can baby them pretty well with a regulator
Totally agree. But it does actually help prove the point that a larger pump with larger pipes and displacement will be more gentle be it boba balls or trichomes. In theory, trichomes should fare better cause are smaller. Those balls and cages are also a big issue.
Not reallyā¦ the scale is way different
Well yeah, @raghanded is a smart guy Iām sure heās gonna remove the cages to test this out. But they would be a non issue with some trichomes.
Where would the trichomes get smashed at? The ball valve?
How do you determine if the benefit is say 1% difference? I have no idea how to determine that. At that size the sample would not be representative and very difficult to count/measure. Truly iād like some insight as I just donāt see it being easy to get statistically representative data.
I sent one out today to a lab in Cali.
What if you started with some amount of bubble hash that you knew the weight of beforehand and then dumped into cold water and pumped through both pumps and then check the yield?
