Mix on Exit Sprayer System

[GLM]

I would like to make a system for my own tank and pump for spraying herbicide on exit like the one in the video. Anyone know where I can purchase the adjustable mixer valve?

Guess it would be ok if you watch the concentrate tank and make sure it’s adding it.

Guess it would be ok unless it wasn't

OP, my dad had bought one from Northern tool a few years back. A quick google says that Northern no longer sells the unit/parts. In other words, no help here.

EDIT: link to manufacturer's site. Maybe available in the replacement parts area.

I dont see a need for it. More stuff to not work.

More headache then necessary. Just keeping sprayer tips clean and solenoid valve unstuck is enough of a headache on our spray rigs.

I dont know if I would trust it for precise jobs.

But neat deal. I've thought about designing something like that I can carry at work. Spray weeds, but also switch over to clean water to wash hands, wash out or fill radiators. I was thinking a split tank design.

What if you have to spray multiple chemical with different spray rates?
