High PSI 12v pump?

[Turkish]

Ok, so I got the Remco 120psi pump with the same 2.2gpm flow of my existing 60psi pump. (We don't need to blast a lot more chemical per minute, we needed the same amount cast a further distance.)

By itself, that got me only about 10' more distance to about 30', so I swapped the nozzle on the Valley sprayer to the next higher GPM flow nozzle. That did the trick, taking the spray distance up to right around 45'.

I changed the hose from the 15' one it came with, to a 50' hose and now I can get back into the thick areas a lot more easily without having to stick to spots where I can drive the SxS right to next to the brush/trees. Now, I can effectively hit trees 95' away from the SxS.

I will still need to add a regulator on the line for the boom, as the only nozzles for this particular setup that Teejet seems to make are limited to 60psi. This will be a cheap and easy addition.

Glad it’s working for you. Just so you know, though, you are using more chemical. Your flow rate is a function of pressure drop. With the new pump putting out a higher discharge pressure, you’ve increased the pressure drop across the hose/gun/nozzle. Do you have a pressure gauge on the discharge? If we have the pump curve and the discharge pressure, we can determine the flow rate.

What gun and nozzle are you using? 95’ is a poke!

Also for your boom… depending on the number of nozzles, and their rated flow rate, your pump is not going to actually make its full 120psi discharge pressure. I bet your nozzle are fine. Depending on the number you might find you’re actually below the pressure recommended for them.

I don't have a pressure gauge at the nozzle (well, anywhere in line at the moment!) the gun is the Valley 16“ long range gun, using their 2.0 orifice. The stretch is great now, and a lot of areas that were off limits will be accessible now.

On the boom, I'm using 4x Teejet XR11008VS flat spray tips 110°. The boom width is about 6.5'. The current setup using the boom gets me solid coverage to about 12" past either side of the SxS.

I'll try running the boom tomorrow and see what the droplet size looks like with the higher PSI pump. An issue I previously had with the lower PSI pump was that the pump would constantly cycle unless I restricted flow to the boom using the cut off valve on the line. Had to keep it at about 30% open to have the pump run continuously.

You’ll be less than 15 psi of discharge pressure with 4 of those nozzles using that pump. Probably will still be ok, though maybe a little below what the nozzle mfg recommends.

Might be able to run one size smaller jet on the interior nozzles and get what you need.

A few tricks with boom sprayers. Give it a practice run. See how much water your using in a certain acerage. Have an accurate way of determining vehicle speed. Some vehicles do fine by themselves with the dash, others you may need to use a cell phone gps speedometer app. Run the pattern on a dry driveway. USe your target speed and do one with the jet sitting there for a few seconds. This works good for testing broadcast spreaders too, seed and fertilizer distribution.

PUmp cylcing means your not at the pumps full gpm. No reason why you couldn't use 1 pump for long range shooting and another for plot spraying.

I use a cheapie high 1 gpm 30 or 40 psi pump. The one that comes with the cheap 15 gal sprayers. I had a boom with some 1/2" pvc pipe the jets are about at the end of the rear cargo rack and about a foot back. I used some Tee's and have 2 pieces of PVC pipe that slides under the cargo rack. I use 2 grey 110 deg fan nozzles at cargo rack height. Color coding is pretty close amoung manufacturers. I got whoever tractor supply sells.

I keep my ATV at 5mph and space my ATV tires about 2 feet. So the next set of tracks looks about the same width as between the tires. The fan overlaps around a foot. and spray a littler over 2ft to the sides. I am about 15 gallons an acre with this setup. Trickier to spray plot with more obstacles or turn arounds is more around 20 gallons acre.

MY little pump 100% of the time, which is just fine. IF your not cycling your pump on/off a regulator isn't needed. Just got to know what your actually doing, and be happy with that much water being used. You can also spray the nozzles into buckets, time it and see eah nozzle gpm on actual conditions. Probably 15 gallons / acre is about as small as you want to go.

IF you are dissovling solids into your tank, a strainer is a must. You can get ones for the nozzles, or ones for the whole line. I usethe 50 mesh and its smaller than those grey nozzle holes.
