Converting PTO sprayer to electric?

[Test_of_time]

I occasionally spray some fields for customer using their 1956 Ferguson Tractor with a 1970's Dorman sprayer. More herbicide comes out of the pump, valve block and high pressure hose than comes out of the nozzles. I'm thinking of converting it to electric power using a delavan 12v pump (11.4 lpm, 60 psi). The sprayer has a total boom width of 5m with 10 nozzles at 550mm spacing. Do people think the pump will be big enough? Your thoughts please.

It might struggle a bit but to give it's best chance use finer nozzles for a lower ( volume )output .

Might have to get used to using lower volume thats all.
Is that the highest flow 12v pump that can be got I wonder.?
Edit.
Only other thing is circulation, which us also necessary for mixing of course , those little throughput pumps struggle to do enough of each .
Mist likely It Will need a new pressure control / flow divider suited to it as well ,

My advice would be to get a rotory vane pump that hangs on the pto. That is what I did with mine and I am happy with it. Did it probably 5 years ago or longer and have used it a fair bit over that time, including the last two days.
Sprayer is similar to yours and I use it on my MF35 or my Same Dorado.

I can get 12v pumps at 14 or 19 LPM. Do I have to use a pressure control? I was hoping to feed the output into a tee piece to feed the 2 booms.

What make/output/price was your pump? The existing pump is rotary vane, PTO. I was looking at electric to save money.

in theory yellow nozzles at 3 bar ( 45psi ) will discharge .8litres per minute, = 8 litrs for ten nozzles, but it will be a very fine spray and you would need to be careful where you are working as the finer the spray the greater the drift.
For a good general purpose nozzle a red nozzle will discharge 1.6 litres a minute requiring a bigger pump.
Remember also that the pump provides agitation to the tank while feeding the nozzles as well so you should have plenty of surplus capacity.
I don't think that a regular electric pump would be man enough.
generic sprayer spares are actually quite cheap and a whole new pump pressure controller and pipework may not be so expensive.

Do you get drift over you also?

Roller vane pump.

They had those as standard as did alot of other sprayers att.
The one in the op has one, the op is asking if it could be converted .

You are right tho a those pumps will pump a much more suitable volume out for the way the sprayer is plumbed. It's a bit easier ( apart from more filling time obviously ) to use higher volumes as well ir , bit more of a safety net with rates etc.

Just an example . Could look in Ebay or somewhere else I guess.

Might need a fitting or 2 but other than that easy to plumb in and everything else can carry on as before...
