What nozzles for delovan 7870 12v system?

[Benny]

Hi friends.

I am building a 12 v dedicated roof pump and I am wondering what size nozzles do I need to order? My electric pump is delovan 7870 7gpm /60psi. I plan on using suttner poly gun and a 1/2 supply hose.

Any help is highly appreciated!

I don’t have a 12v system yet and I’m still very new, but I assume it would follow the same principles like pressure washer nozzles.

So to keep your 60psi at the end of your wand for a 7gpm I would guess something like a 60 orifice size? Maybe up our down a little due to hose length yada yada.

But like I said. I might be way out to lunch. Nozzle charts are still a little confusing

Cmon fellas, at least BS and lie that you’ve attempted to search in the search bar and couldn’t find it. At minimum lol

Nozzle orifice size for roof pump?

This is what I use, thanks to @Racer. 1/2in Barb to thread 1/2 threaded pvc ball valve 18in 1/2in threaded pvc pipe 1/2in pvc female to female 1/2in male to 1/4in female brass reducer 1/4in quick connect for your nozzle [Screenshot_20191219-230541] It can all be found at home Depot. The nozzles I use are 2540 and 0040. I have a 5.5gpm with 200ft hose. The more hose you use the less GPM you get but I wouldn’t roll with less than 200ft

Took me 4 seconds.

So how do I calculate the nozzle for 7gpm 60 psi? All the charts I saw start with 500 psi.

Search again bud, rinse and repeat haha.

Buy four nozzle sizes 20 30 40 and a 50 go play in your driveway geeez. This will cost you 20 bucks then when you decide on one you’ll still have four sizes too play with when you get a new pump or make changes. Then you’ll be able to help yourself next time
