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.
