Custom Sprayer

[bostonrats]

Hello to all,

Here is my version of a custom PTO driven sprayer. Most parts are from TSC or Home Depot. The pump is a hypro 6500XL, TSC 2111815. It will drive the system to 300 PSI. The pressure valve is TCS 2106705. It's set to dump liquid back into the tank over it's setpoint. It doubles as an agitator as the system pulls from the botton and dumps on the top.

The high pressure hose is TSC 1819606 and TSC 1819999. These are 1/2" and 3500 PSI rated, rugged and overkill. Pump to manifold is 5', manifold to spay wand is 10'. This could be a bit smaller in diameter if you like.

The low pressure, intake side is Home Depot 3/4 to 1" vinyl hose.

The pump is mounted on a small piece of channel, a spring on the right side as a torque arrestor. The spring is TSC, I think it's sold as gate or fence hardware. You could use solid chain, there is very little shock when put into gear, also very little rotational force.

The intake pipe is 1/2" PVC from Home Depot with an angle cut at the tip to allow flow without suction to the tank bottom.

The tank is on a TSC carry all, that doubles as ballast holder in when needed. TSC 2128210.

They spray wand is TSC 2107044. This was a problem at first, it's rated at 8 GPM. 800 PSI. Not enough flow at 200 PSI. I took off the aluminum tip and drilled it out about 5 or 10 thousandths. If you do so, be sure to keep the new orifice size under the edge chamfer to allow for spray. If you go bigger I would guess the hole would not spry well if squared and would need a new chamfer inside and out. I could be wrong on this, have not done too much with nozzles.

That's it. The total cose is about $200 to $250 without the carry all. It will spray about 20 feet and is great for my semi dwarf apple trees and general spraying.

Best to all.

Good job.
I like how the whole top can come off to clean it out.

Is that the high dollar Roundup ready pump?

Thanks Berniep. I wasn't sure if I wanted a sealed barrel or ring top, glad I went this way. I shot roundup and really wanted to get it all out, pulled off the top and used some detergent on a brush to rinse.

Hi Bill,

Yes, it is Roundup Ready. They shipped me the Silver series but charged me for the standard blue. I'm not so sure you couldn't shoot roundup in the blue, especially if you flushed it afterwards. I did find a huge spread on prices for these pumps, one really needs to shop for the best deal. Ebay has the Silver very cheap right now. I use Imidan on the apple trees, a wetable powder. That's the main use for this sprayer, 19 apple trees.

Best to you

440# of liquid plus the weight of the barrel, carryall and plumbing looks like a lot of weight out on the back of that CUT. Pretty slick setup though, I like the removabale top barrel, that is a good idea.

Just curious. Some of the suff I put in my sprayer makes a lot of foam. Do you get a lot of foam with your return going into the top like that?

Hi Berniep,

Foam? I get foam like Lucy and Ethyl on a bad day doing laundry. I don't have a problem though since my intake pipe is right on the bottom of the barrel, I cut a chunk out to keep be sure it pulls liquid instead the barrel. it's a about 1/2" up and at a 45 degree angle. When I'm done I pull the tie downs off, pull off the lid and send a huge river of foam down my driveway. It's mostly air and I don't want grass where it goes anyway!

I was wondering about an anti foam agent but since it doesn't create a spray problem I'll just live with it. The foam was with Round Up, have not shot Imidian yet. To me it's a small issue compared with a greater potential problem with poor agitation. My old sprayer was a plastic 33 gal trash can with lid hooked to a 6 hp gas driven power washer. I fed the hose input from the bucket and it worked fine for years. It shoots pretty much just like when hooked to a garden hose. To agitate I used an air caddie stapped to the rig and weighted a hose to the bottom. A slow air leak made bubbles that kept it all mixed well. I had to hope I didn't run out of air. I had also used a 12 volt RV water pump in the past.

This set up is best so far, agitates and allows me to put down more liquid in less time. It was cheap and pretty easy to build. One thing to note, the fittings need to be tight even when testing. You will be surprised how much pressure the pump makes. I wish it would shoot more than 20 feet, maybe a new nozzle at some point will get me more distance.

Best to all of you, I swear if we had more farmers and the like our country would be far better off. One farmer is worth 100 Detroit engineers, the kind of engineers that can't figure out how to reverse a ratchet but design our crappy cars.

Well the onlty problem with that is it can affect the mix, If your chemical is tied up making foam then it's not in the mix. Probably not enough to notice with roundup though.

I think if you put an extension tube on it you would find that you would still have plenty of agitation, I bet it would still look like a jacuzzi in there or even put a "J" on the bottom to direct the flow upward. Most ag sprayers I have seen have the return line going into the bottom to stir the fluid at the bottom where particulates would settle. But as long as it works I say you have a great sprayer.

You should definitely get more than 20 feet out of you wand. I get 30 or more out of my little 2gpm electric pump. What is the pressure when the wand is spraying. You might have an obstruction in there somewhere.

Hi Berniep,

Thanks for the note. I'm not so sure that there would be a higher concentration of chemical in the foam than in the tank itself.

On the exention agitator tube, I've seen designs where they branch off the main output before the gun and relief valve. I didn't know how much I would have to spare so I opted for the over pressure to do the agitation.

On the spray gun, I guess I'm at 20 feet, I didn't measure it. I can get a bit more if I push to 300 PSI but run about 200 to 250 to keep the system under less stress. I have noticed that even when my trigger is fully pulled I still have plenty of pressure and am dumping back into the tank. That tells me I can go with a bigger nozzle....which I might experiment with.

In the end it's a pretty easy and cheap project. I hope some other folks are helped by the photos and make thier own similar spot sprayers.

PS Anyone out there with a better spray gun that give more distance?
