Want to build a 12V sprayer

Background: We have 15 and 25 gallon sprayers. My issue is, for spot weed control, only need about 1-2 gallons of spray. Where I spray is hilly so sprayer has to be at least half full for the suction line to be submerged which means too much spray. Have tried blocking up one side and extending the suction line into the "downhill" corner but that's sloppy at best. THe perfect solution would be a five gallon bucket , pump and wand. No problem building it, IF I can find the parts. Haven't been able to find a reasonable source for sprayer parts. Have even considered buying this sprayer from Rural King and cannibalilzing.

https://www.ruralking.com/country-wa...ssn-01-015a-rk

ANswering the obvious, why don't I use a regular pump up garden sprayer? Not as young as I used to be and a lot of walking involved.

Online search for sprayer parts leads you to the big Ag suppliers. Anyone know of a source for small sprayer parts?

Thanks for your time.

Re: Want to build a 12V sprayer

I considered getting a 12V 15 gallon, but I ended up with a two pack of two gallon pump sprayers. I rarely need more than two gallons at a time, let alone 15. But I agree, hand pumping can be a pain, literally.

But I've been curious about using compressed air though something like a tire vale drilled into the sprayer tank. Maybe using one of those portable air tanks?


You wouldn't be sucking/drawing the fluid through a pump. You'd be forcing it through the normal system the same as is done by hand pumping.

You'd just have to be careful not to over pressurize to the point of rupturing the sprayer tank. Air valves and gauges aren't overly expensive.

Re: Want to build a 12V sprayer

Maybe one of those small 12V air compressors used for car tires would work,if it was set up properly so as not to over pressurize the sprayer tank as suggested above..

I know someone who put one on a portable air tank and added a 12V lithium battery from a jump starter to power it,so he could use an air impact gun far from his shop..
It did work well for pumping tires up,but the air gun would only take one or two lug nuts off ,then you had to wait for the tank to pump up again,and the battery didn't last too long..

Re: Want to build a 12V sprayer

Thanks for the responses. I thought about carrying around a pressurized tank or tank and air source, but think you'd need a regulator to get any kind of duration out of just a static pressurized tank. I've got a pretty clear picture of what I want with a five gallon bucket and lid, etc. Maybe I'll find a sprayer at a flea market or something. Amz. has a 1GPM pump for $25, the wands are an issue, can't seem to find any unless they're for power washers, etc. Hmmm, maybe cannibalize one of the pump up sprayers in the barn for wand and pickup tube. Add some plastic tubing.....Hmmm. :-)

I think Northern Tool carries small sprayer parts.

Re: Want to build a 12V sprayer

Tractor Supply Company carries sprayer parts. For large tractors and smaller pull behind sprayers. Also all kinds of garden hose type fittings, brass and nylon.
That is where I bought my wand. Can buy off their web site and ship it if need be.

I came up with a 1.2 GPM 12V pump from some where. Had it here for a few years. And/or I can take the pump off my pull behind sprayer and use it instead if need be. Pretty easy to remove/replace.
Used a 5 gal red gas can as the tank. A cheaper white plastic water can may be better. Took the spout off, drilled a 3/8" hole through the plastic piece that you use to seal the can when the spout is turned inside the can. Put a hard plastic tube 3/8" OD through it as the pick up. (Wanted to put a filter on the end of pickup tube, but never found one.) Connect that to the clear plastic hose, and into the pump. 3/8" ID clear plastic hose fit over the hard plastic pick up tube and I used a hose clamp to keep it tight. Pump uses Garden Hose Thread (GHT) connections, so found a female GHT to 3/8" barb. fitting.

Did not include a return to the tank. Pump shuts off at 50 psi. Pretty much as soon as I turn off the wand.

Output on pump I used a GHT to 3/8" barb. Bought 50 feet of 3/8" ID, clear plastic hose at local hardware store. Made a place to coil up and hang the hose on the back. Also have a pressure gauge between pump and hose. Need correct fittings to do that. Just need to figure out which ones. Mine were 1/2" NP. Then a male GHT on the end to attach sprayer hose. Some pumps can have a pressure gauge out the top. Like my old one in picture.
Wand I bought at TSC had 3/8" barb on it if IRC.
I mounted the pump and a on/off switch to a piece of plywood. Wired with battery clamps, and a fuse, to connect to battery.

I have a carry all basket on the back of the GT I sit the gas can in, and mount the pump. Can could be strapped to top of hood. Or build a simple flat weight carrier off the back to strap it to.

Don't have any pictures. Never thought about taking some. Been using it about 5 years now. Found a couple for reference in my pull behind sprayer folder. One has an old brass fitting I soldered together from a long time ago.

Any fittings you need, use nylon. There are a few online places that sell all the different nylon fittings you may need. Do a search for GHT nylon fittings. Then look for their catalog.

Hope this helps.

Re: Want to build a 12V sprayer

I used to be frugal, now I'm cheap.

When I saw the pressure washer cart set out for trash I had an idea. The 15 gallon sprayer was overkill and needed a 12 volt battery ( corner lot, subdivision ), but the 12 volt pumps are readily available on Amazon or ebay.

With the typical 2 gallon garden sprayer parts as a start, I assembled a plywood base for the battery and cut the bottom 3 inches off a 5 gallon bucket, which holds a 3 or 5 gallon bucket.

More cut and paste from scrap around the shop...toggle switch and such...I have a tow around sprayer.

Pictures to follow breakfast and shower. Retirement slowed my morning.

Re: Want to build a 12V sprayer

I pump out of a 2.5 gallon plastic pesticide jug with a 1.5 gallon per minute ag pimp that shuts of at 50 PSI I use it to drip roundup in a wiping machine rooer to wipe weeds, but it could be used with a wand as well. This is on a ride on machine as the battery, pump and material jug would be too akward and heavy to carry

Re: Want to build a 12V sprayer

Maybe an old 12V water pump from a junked RV might work --that would be a cheap way to get the pump...not sure if one would hold up to the chemicals or not ,but probably would at least for awhile..

Re: Want to build a 12V sprayer

All of this pump and battery stuff doesn't solve the OPs issue of off-level use since you're still dealing with suction.

Tank pressure will still have some of that, but not as bad.

OP, have you considered the backpack type with a hand lever? They pump easier than the conventional plunger type.

Re: Want to build a 12V sprayer

Problem solved. I was talking to my brother about this and he reminded me of a Craftsman tow behind sprayer I'd given him about twenty+ years ago as I wasn't using it. He still has it, pump is shot, but everything else is there. It's a kind of "oval" ten gallon tank which makes it easy to only put a few gallons in as skinny portion of the tank is the bottom. I'll put the suction hose in one corner and make sure that's the downhill side when spraying. There may be a moral here, but not sure I want to become the packrat my brother is. :-)

Thanks for the responses!

Re: Want to build a 12V sprayer

I took refillable stainless steel fire extinguisher ($5 dented at garage sale) added a tire valve. Fill to about 20 pounds. Will spray almost 50 feet. Very pleased with the result.

Re: Want to build a 12V sprayer

Skip the electrics and spray nozzles. Go with a roller. Simple design. Very little to fail. Or maybe build one of your own?
