How much do larger tips reduce your psi?

I’m not sure what you are saying, these are not quick connect tips so you would have to put the meg nozzle in a fitting (use some tape) then connect it to your wand. Here is a Jrod which can hold four nozzles, people use it for high and low pressure soaps and rinses. I have no idea why it is called that, it is just four connectors welded together. JROD 4 Way Nozzle Holder - Pressure Tek.
You can also buy individual connectors if that is what you desire. The same place has 40 degree nozzles as well in a wide range of sizes, just select the one(s) you want. They also sell quick connect nozzles if that is what you want. I’m not advocating Pressure tek, although I have ordered a lot from them, they are one option available to you among a host of other places. Some members on here have their own personal preferences for suppliers, pick one that works for you. I’m in PA and PT is in Ohio, so shipping is a little quicker and cheaper for me than some other suppliers.

Look, I’m a padawan sprayer, not a jedi, Marinegrunt is telling you what you need to know. I found PT website to be a little difficult to use, but they answer questions rather timely if you have any. If I want to order a (fake number inserted) 40025 I would expect to see it listed that way, but he lists them by selecting the nozzle degree first, then you select the orifice size in the drop down.

Hope this answers your question.

Edit: I forgot to mention that the forum isn’t just a forum, they actually sell PW supplies. ON the top of the page it will say Power washing equipment, so check for nozzles there as well.

I gotta tell you, the easiest way to figure out what nozzle you want is by using this calculator. Enter your gpm and the psi you want, and it’ll give you the closest size. The nozzle size will be the last two digits and the first two digits will be the fan angle.

Order stainless nozzles when you can, and a stainless 1/4 fpt plug for each

Just thought about this as I was organizing some of my Meg tips, do you have to include the pressure loss you encounter with hose lengths when figuring out nozzle sizes for the surface cleaner ?

Example:

You want 2500 psi with your 2 tip bar on the surface cleaner.

You have an 8 gpm 3000 psi machine. (Not me)

Chart says to get two #5 orifice tips. Right ?

But let’s say I have 250’ of 3/8 pressure hose.

hose-friction-loss

Chart says that you will have 750 psi loss from the pump to the end of your hose.

So now I really have 2250 psi at the end of the hose due to friction loss.

How do you achieve that 2500 psi ?

Smaller orifice tips?

Let’s discuss

NP + FL = PDP

NP = Nozzle pressure
FL = Friction loss
PDP = Pump discharge pressure

So two #5 tips at 8gpm would give you approximately 2500psi for your NP

Your FL for 250ft of 3/8 at 8gpm is approximately 750psi

Your PDP would be approximately 3250psi

This is my first post, I am a firefighter certified in pump operations which goes hand in hand with pressure washing. Been reading here for a long time figured I could contribute. Hope that helps

Well, kinda. Unlike a centrifugal pump, Hale or Waterous, on a fire pump, where you aren’t limited by anything but the max rpm off the engine, piston pumps have a set pump discharge. If it’s a 3k psi pump, pretty much regardless of what tip you use, you aren’t going to get much more than that. Best you can do is cut down on friction loss by not using elbows, couplers, ball valves etc.

OK gotcha, kind of what I was getting at that in his scenario he is overworking his pump

So in my scenario, my main question is, does hose length friction loss math matter when configuring tips for your target psi?

Yes…

Put in two 2504 nozzles and don’t over think it

You could be chasing 250 psi till the cows come home. As stated don’t overthink it, you have a tank full of bleach for post treating and a shiny new hot unit, you’ll be fine :ok_hand:

I already have all my Meg nozzles! Just some late night thinking my tired brain decided to do lol. I think it’s a good thing to have discussed on the forum for newer folk

Folks, how do I choose a soap MEG nozzle using this chart for 4 gpm pump?

#40. 0040 and 2540

Max is right. Or just go here. Under 100 for soap tips. First two digits are your fan angle, second two digits are the orifice size. If it’s five digits, then there’s a decimal before the last digit (25 degree 2.5 orifice would read 25025)

Didn’t want to make a new thread for this and couldn’t find much on search. Kleen rite has a variety of 8 gpm turbo nozzles with many different orifice sizes, from 7 to 12. Which one would I need for an 8 gpm at 3000 psi machine?

Damn bud you just gave him the answer on a platter, you must have gotten your 8 hours sleep lol.
