Which nozzle is a 25025?

I have a 20" surface cleaner and my machine runs at 3000psi - 4 gpm. Most of the time I'm using 100' of hose, sometimes 150-200' to reach the back yard. A guy recommended I use 25025 nozzle for my 2 - bar swivel.
 
A 25025 is a #025 orifice with a 25° spray pattern. 2 of them will give you the equivalent of a #05, which is as close as you're going to come for a 4 @ 3000.

Which sounds like the 2.5 gallon 25 degree tip. Thanks Russ!

My machine is an Alkota @ 5.5 gpm and 4000 psi. I have a20 inch BE 2 bar surface cleaner. would I be using the same nozzles/tips as above?

If you are running very much hose I would think a 25025 would be appropriate. You could also run a 2503 but your pressure would drop a bit but you might get a tad more flow.

On edit I just noticed you said two bar. So you have 4 nozzles? I don't know how to answer that. It is going to take a real small orifice. Does spraying systems make anything smaller than a 02 ?

So in theory why not 2502 for my setup?

Because your machine is rated 3000 psi not 4000 psi. All nozzle gpm ratings are baselined at 4000 psi. If you have a 4 gpm nozzle and put 4gpm through it, it will develop 4000 psi back pressure if your machine is capable. Even if you have a pump rated 4 gpm at 10000 psi. When you go to lesser psi machines you have to get larger orifices. There are nozzle charts available. Just searc here. Just remember to divide that orifice size by how many nozzles your surface cleaner has.

Steven, do you mean you have 2 spray nozzles or 4, there are lots of ways to talk about spray bars.

If you have 2 nozzles, you would use 2 of the 25025 or 2 of the 25030 nozzles, it could go either way.

If you have 4 nozzles, you would use 4 of the 2501 nozzles which are very small and hard to find but are available, running only 5.5gpm I would not use 4 nozzles on a surface cleaner, only on 8gpm or more.
 
CL, that is a common mistake, confusing the orifice number with gallons. That number ONLY corresponds to gallons per minute at 4,000 psi. Other than that, it's just an arbitrary number for the orifice hole. It doesn't even correspond to an exact size, either US fractional or metric.

Steven, you need a 0225 nozzle, and since there is no such size, your alternative is the 025.

What about a 3 bar or 3 nozzle unit. Is there an orifice size to accommodate that unit using 5.5 GPM's?

Russ can you post a link to these?

Nope, not in the store yet. Call me.

You'll have to settle for 3 - #02 Rance, the equivalent of a 06.

Alright! I got everything I need. I think this new hammerhead comes w 2502's, but I'm going with the 25025's as suggested. Thanks again!

I have the cat 66dx. What is back pressure? Will the 2502's hurt my machine? Looks like the tips have red glue around them.
 
Back pressure is the psi between the pump and the nozzle. Where large orifices drop pressure too small an orifice will cause too much pressure and the unloader will simply bypass some of the flow effectively reducing the gpm flow through the nozzle. You don't want an undersize nozzle because it reduces flow works the unloader harder and works the engine and pump to the max. All while effectively having a smaller pump.
 
I run 5gpm 3000 psi, and I have to keep my pressure low, down here in FL. I use 25035's to get about 2200 psi. Sometimes I run 4's and even 5's. I got to the point that I can tell what pressure I should use for certain driveways, the cream comes off very easy around here. Stronger chems, less pressure, that's my new motto!
