Hello everyone,

I find this very interesting since I was planning on building one myself. I wish that I could watch the video but Youtube gives me the "This video is unavailable on this device" message, no mater which device I try to watch it on.
I am interested in the output and if the gravity feed is sufficient (Bertolini pumps usually need a few psi at the input). I also see that no static mixer were used...I wouldn't have thought so.

Regards to all!

Can confirm, I'm getting the same error in multiple browsers, even when viewing the video un-embedded on youtube.com. Have never seen that error before.

At the entrance to the pump 1.5 atmospheres
Corrosion was only in the mixer, in one (Poly) of two nozzles (from the truck), the needle valve rusted, it changed every 2-3 months.
No more has been replaced in the system.
The system works 8 years. The system was turned on every 2 weeks. All this time, the system was charged with Iso and Poly components.

Many thanks for all the info.

These will be very useful in the design of my project.
