I have an AR RSV 4G40 pump and it comes with 4GPM at 4000psi from the factory. My nozzles are 04, however I installed a pressure valve with external baypass. When I press the gun trigger, on the pressure valve at 4000psi, water comes out of the baypass at 0.973 GPM. Without the nozzle at the end of the boom, 4GPM comes out. And with the 04 bushings, only 3.17GPM comes out. Should I go to 05 or what could be wrong?
t sounds like the reduced GPM when using the 04 nozzles could be due to an orifice size mismatch. To achieve closer to the full 4 GPM output at 4000 PSI, consider switching to a 05 nozzle size. This may better align with the system's pressure and flow needs while maintaining optimal performance.
If they came with your machine they should be the right size nozzles. Unless, you got a used machine then I recommend checking the nozzle chart to make sure you have the right size. Also, remember that nozzles wear out and should be replaced often
My fan nozzle that came with the water pressure washer is only strong on both edge of the fan. The pressure between the is just like it's coming out of a normal hose. That means when I tried to was my deck with the fan nozzle, there's only about 1/16 inch of both side of the fan are actually pressurized。 Since I am not sure how to tell if a nozzle has even pressure I have not used the pressure washer after 2 uses a couple years ago.
The tips that came with my 3300psi/2.5gpm pressure washer are sized correctly (the code stamped on each tip ends in "26", meaning 2.6 orifice size), but the 25 and 40 degree tips have "sharp edges". By that I mean the fan pattern is needle-like at the top & bottom edges. These needles have a tendency to tear into paint and wood and I can see & feel them even when the pump is off. I can minimize the problem by keeping the tip away from the surface and keeping it moving quickly, but I'd rather the problem not be present at all. Do all spray tips have needle-like edges, or do I need to get better quality tips?
Hi bro, I have a kranzle pressure washer made in germany model K2160 TS, rated flow rate is 11L/min or 2.9 GPM if you convert it to GPM (am I correct?). Max rated pressure is 140 bar or 2000 in psi. should I get 4.0 orifice nozzle? and since my pressure washer has a pressure regulator (or valve unloader) that I can adjust, lets say I would like to adjust max pressure to 1,800 psi for car wash cleaning, what orifice should I get?
Your conversion to 2.9 GPM is correct. A 4.0 orifice nozzle should be suitable for your goal of maintaining 1,800 PSI for car washing. Adjusting the pressure valve on your washer should help fine-tune the output as needed.
How do you know the actual psi your pump is producing? You can measure it with a given nozzle but that changes based on the orifice size. How do you determine what psi to use in the equation?
Every pump is rated for a specific PSI whether that is soft washing or pressure washing. You can usually check the manufacture website to get the PSI rating.
For a 4 GPM pressure washer rated at 4400 PSI, using an 04 nozzle is recommended. This orifice size will ensure you maintain proper pressure and flow without overloading your system or causing damage.
I have a good amount of concrete and flag stone to power wash. I have a gas powered Briggs & Stratton brand 2200 psi/1.9 gpm washer. Would a turbo nozzle work well with this machine? I find it seems to be tedious time wise in using the nozzles that came with it. Thank you for any advice you can give.
A turbo nozzle would be a big help. Just be careful not to damage the stone powerwash.com/shop/accessories/pressure-washer-nozzles/turbo-nozzles/a-turbo-nozzle-4000-repair-kit/
Hello guys. I have a nilfisk Pressure washer with 190bars max pres and 650l/h max flow. The correct nozzle for this is the 3.5 but i already have some 3.0s. Is the 0.5 difference big? Will i overstress the motor? Should i buy the 3.5? Thanks! :D
The nozzle size *OPTIMIZES* the performance of the pressure washer, but cannot exceed its rated power, right? For example, a pressure washer rated 4000 PSI and 10 GPM would have a nozzle size of 10. If I use a size 5 nozzle, I should still only get 4000 PSI but reduced to 5 GPM. If I use a size 20 nozzle, I should be getting 10 GPM, but only 1000 PSI.
Is there a chart for this kind of conversions? What might happen if I increase the GPM and reduce the psi by using a bigger nozzle? Will my washer brake? I have 2300 psi 1.2 GPM

You need to get tips with a larger orifice, you want to be under 1000 PSI for wood.
Great video you guys saved my pump thank you !
Really need some help selecting the proper orifice size. Which size will I need for a 1900 psi 1.2 gpm electric pressure washer??
Here is the nozzle chart on our website. Just match up the columns and you should be good to go!

@@Powerwash thank you! I have found a few of these charts and some suggests as big as a 2.5 while according to your equation I'm getting 1.7.
Glad we could help. This chart should be exactly what you need as this is the same chart our professionals reference when we get calls about nozzles.
I have a new 4200 psi 4 gpm pressure washer. It came with nozzles, however there is a lot of kick back and pressure. What would you recommend? TIA

Hello guys.
I have a nilfisk Pressure washer with 190bars max pres and 650l/h max flow.
The correct nozzle for this is the 3.5 but i already have some 3.0s.
Is the 0.5 difference big? Will i overstress the motor? Should i buy the 3.5?
Thanks! :D
You should be ok. To be off by .5 nozzle size is not uncommon
@@Powerwash Thank you very much for the quick reply!
Is it the same process in choosing a rotary nozzle??? Thanks
Yes
@@Powerwash And may i ask also...can i use a telescopic wand on a 2800psi @ 2.5gpm machine....thanks again
@@anextday yes you can but that's not a lot of cleaning power. I would move up to a minimum of 4000 PSI at 4 GPM
@@Powerwash ok thanks again bro
Hi,
On a 13hp engine with a (5.5 gpm @ 3500 psi) i should be using a 6.0 nozzle? not a 4.0 correct?
Yes a size 6 is the correct size
do you guys sell a size 12 nozzle?Im trying to reduce 2900psi 2.3gpm to 100psi to softwash
Just use a garden hose with a multi-pattern sprayer and use the jet pattern
I have too much pressure on my machine, what can I do?
Have you tried using a larger nozzle to reduce pressure
@@Powerwash yes I have. I use the 25 and 40 degrees nozzle but to each nozzle still the pressure is high and can destroy property
Is turbo nozzle better than zero degree nozzle
@@mdmuhibshaikh9560 yes
@@kingsglobal6219 increase the gpm on the nozzle. If your machine is 2.3gpm try a 3.5gpm nozzles on 40degree and see how that goes.
is a 00100 just a 0010 or is that totally different?
