Lately have been thinking about recirculating booms. Does anyone run them? Likes, dislikes?
To me, it would solve a lot of issues with chemical hangup issues in boom plumbing. We have not had trouble this year, because we have been so anal about cleaning lately. As a producer with our own JD high clearance, I may spray wheat for a week or two with the same chemical and it is a pain to rinse boom out every night ( I don't), or charge boom the next day.
Even though we have stainless pipes, there is a couple miles of rubber hose feeding those pipes. I think chemical sitting in the hose tends to stick over time.
I think a recirculating boom would help. At the end of the day, I could just run some rinse water thru the boom and push that back into the tank. Then the next day I could recirculate tank and boom together, and start spraying right away with no boom charging needed.
I realize the nozzle bodies would either have to be an AIM type solenoid, or an air operated check valve( Like Hypro has available ). And you would probably have the boom pipe in two long sections on each half. An electric operated valve could be at each end with piping returning to the tank.
With these type of nozzle bodies, you could make up as many auto sections as you want and the size you want them to be.
Other than added complexity, what does everyone think of a sprayer set up like that?
I sure would like one. (I think)

I know a guy that did his 4830, I don't think he needed air valves on each nozzle but just put in heavier non drip valve springs so the nozzles don't open as easy. Put a dump valve on the end of each section and it works well.
I would like to do my sprayer too but don't know whether to spend money on this one or wait til I can afford to changeover. We have a lot of odd shaped fields, I would love to have individual nozzle control, every year we see our overlap showing up in one crop or another.

I love the idea but having trouble with thinking through the execution?:confused:
Say you have 10 sections, you have 20 place to cycle back to the tank?
Unless we're think something different draw8 the hydro end boom caps are just for eliminating air in the lines to prevent run on and lag.
How is your's setup mb?

What if left and right were each full length halves. Valves that could return flow to tank, placed at each end. Controlable nozzle bodies (air or electric) could make up whatever section sizes you want. ( i think)

Rogater have an air flush system
End of the day just empty the boom with air then because there is no water to push out it primes straight away next time

Main concern for me is pressure drop along the boom. At high flow rates or low pressures, boom pressure at pump side could be 10 psi (guess) higher than at return end.

See tables: Pressure Loss in Schedule 40 Steel Pipes

My boom only recirculates when the main control switch is off. Chemical is run back into the tank from the end of each boom. Pretty simple but nice for rinsing and charging the booms.

When the main boom spray switch is off chemical recirculates from the end of each boom back into the tank. Once you hit the spray button it closes a electronic valve that allows the machine to spray normally. It doesn't do anything if you just shut off a couple sections. After rinsing I fill the sprayer with whatever is required jump in and spray. I never have issues with chemical left in the booms or just water and no chemical. Pommier is the company that makes my boom and the recirculating kit. You could certainly call them and ask some questions. Feel free to ask me as well if I have not answered your questions. The big one, is it worth the money? I don't know but once you have had it you wouldn't go back.
Thanks mb.

Pressure drop would be no different than conventional if the center of each pipe is the feed and the end of the pipe is the return. In fact there may not be a
pressure drop cause the fluid is always circulating and won't have to go from 0 to (x) velocity upon engagement

Less pressure drop as when all the sections are shut off chemical recirculates so its always flowing.

I forgot to take pictures today. Boom is a pommier.

hey guys my name is Dallas and i work for a company called Gaber Distributors. I am the technician that installs and plumbs the Pommier aluminum booms. I have only been here since Oct 13 but have installed the re-circulation on 7 machines since then and its actually not all that hard. its a great system in the sense that allof the chemical is always moving and you never have problems with the chemical settling out. We use stainless steel piping and some rubber hose along with arag nozzle bodys that are controlled by air. I wire it all to work with the section controls that are already on your machine. anymore questions call the shop and ask for me.

How hard(expensive;)) is it to retrofit an existing sprayer with standard plumbing(no AIM) to become a re-circulating boom? Can most of the existing wet boom and nozzle bodies be re-used?

I'd imagine you should be able to reuse the wet boom nozzle bodies. Shouldn't be much difference there. It'd likely just be adding on the plumbing/wiring side of things.

@Dallasmench
What exactly would you need to add for a recirc setup to get by?

The recirculating system just seems like that much more stuff to clean out each swap. Pretty happy with the air cleanout on the rogator and on charge up as soon as they are spraying your good again.

I'd love to have recirculating system, no worries as to how many gallon to charge the system and you are at full strength when you start spraying instead of guessing. I don't see a problem with flushing out system.

I would have thought easier to clean a re-circulating boom??? I do agree that an air blow-out system would be next best for sure.;)
