Bateman Sprayer twin line purge?

[Phil P]

So, I’m getting a bit sick of having to sit and p!ss a load of chem through the booms to get to the outside section!

Has anyone fitted or got a line purge system on a twin line RB15/16?

Is it possible to fit?
Any chance of some pictures of how it’s piped in please if you have one.

Thanks.

Not familiar with Bateman but to purge lines back to tank you would need recirculating boom plumbing I would think.? Have you got air shut off nozzles or electric valves for each boom section

There’s only one air shutoff per section then each holder has a chem saver valve. That’s why I’m not sure if it’s possible as any pressure over half a bar in the section and it would start spraying!
I was thinking perhaps I could pipe between the suction side of the pump and the end of each section with a tap to turn the purge on/off. Then drop the pressure right down, turn the sections on and let it sucks the chem through the lines to purge them.

Would this work?

Sort of I think, knight had a similar system “laser recirculation” but not brilliant. If you have air I would replumb the boom to constant recirculation much better system and cleaner too, not difficult to do really air shut of nozzles are your biggest expense or electric duo but I would stay air we did ours a few years ago

I've been thinking about this for my HiLo. The best compromise I can think of would be drilling and tapping a small (maybe 3/8) adapter into the pump pressure side of the four air over water shut offs then piping back into a manifold to a single 3/4 pipe with a tap which then returns to the tank.

Leaving the tap open while agitating on the journey to the first field would purge the pipework before the nozzle lines leaving only those to purge in the "traditional" manner. Should save a fair bit of time and chem.

Actually, I think you would only need to tap into the the two air valves on the outer sections as the line passes straight through the inner valves.

Tbh full recirculation would be simpler to do and simpler to use adding more pipe and valves will only give more places for contamination to occur as well

Simple yes. Cheap no.

Yes that’s right, to be honest though it’s the outside two meters that seem to take forever to get chem too! There always a 2m patch of weed in the corner of the first field I start spraying (usually the one right next to the house?), doesn’t seem to matter how much I p!ss out before I start.

May give Bateman a call next week see if it’s something they ever fitted (never seen it on a twin line though}, they’re always very helpful on the phone so probably worth a chat.

 

[Zebbedee]

It’s not dear if it improves it though! Not wasting chemical Purging lines, upgrading to better nozzle holders, cleaner boom lines a few advantages but yes it does cost a few dollars

Not a Bateman, but I fitted a purge to my single line boom. At first tried to run it on the suction side of the system, but to many potential air leaks, so switched it round to pressure side. Run at less than 0.5 bar while folding up the empty cardboard boxes and bagging empty cans. Ready to spray straight away.

That's similar to what I did, with a pipe running back to the tank from the end of each boom section, passing through a non-return valve and a on-off valve. With the pump ticking over, I open the valve and let the spray be pumped back to the tank, at a pressure of 0.5 bar. When I think its ready just turn off the valve and its ready to go. All at a very reasonable cost.

Thanks, I’ll give it a go then and see what happens. May just try piping back to the tank for a start with an on/off tap and see how it goes. Even if I just try one line to start with. ?

My RB 25 has purge but I understand it s a different set up, but if you have triple nozzles could you just plumb a return line back to tank from each boom end , then ( I know its a ball ache) when unfolded turn the triples to a point where they wont spray and open a return to tank tap, hence not relying on the chem savers.

Can’t turn individual nozzles of on the twin line booms, there’s not enough room to fit the triple nozzle setup either. To be honest though I couldn’t be arsed turning 48 nozzles every time I changed tank mix ?

Hi Phil On our Bateman RB 16 each of the 4 boom section ends terminates to a 3/8 pipe which then goes back down the boom and then to a lever valve in to a manifold from there it goes back to the tank.
So the boom and lines up to the lever valves are always pressured.
Switching on the nozzles is done by air pressure going to the chem saver nozzles.

To prime just open the 4 lever valves for a few seconds then close them. usually do this just after filling tank with water and chem.

That's the same set up as my 25, led to believe phil's 15 doesn't have all the air valves as ours, just one per boom section.

As @fieldfarmer says, I only have the one valve per section, that’s why I wanted to see if anyone had a purge system on the same setup as mine.
Does the valve bank with the taps just go back to the tank or to the suction side of the pump?

Back to the tank

Back to the tank

Thanks ?
