If I connect 2 pressure washer pumps to a motor, will I get double the output????? help?
Jan 21
ok here is the situation, I have two 3000PSI pressure washer pumps, and a gas engine, If I took both and connected them to the motor, supplied enough water flow and used a coupler to join the output on both, will I get 6000psi of water pressure or will I end up creating back pressure and possibly damaging the pums, or will I get killed in the process.
I hope someone with an engeniering degree reads this, maybe I can get a valid answer. oh and forgive me for my spelling disaster here….he he he
If you have enough power in your gas engine to run both pumps, you may get almost twice the volume output of one pump at 3000PSI. For your next question, try the ‘Check Spelling’ feature located above the box.

You dont need an engineering degree for this. You cannot do this and this is why. First of all if this could be done, the pump that puts out more psi will take over and supply your pressure hose ( even though there both 3000 psi pumps) also your going to need two unloaders and two flow switches for each pump. even if you put everything together, your still going to have the same problem and eventually one pump will seize up from heat.
What you can do is sell both pumps and get a pump thats at least 5 GPM or more and install that to your engine ( only if your engine can support it.)
I dont know what your using that pressure washer for but 6000psi is NOTHING. Always look at the GPM, thats what does the job. The more water the better the cleaning is. 5 or 6 GPM at 3000 psi is 100 times better than 2 or 3 GPM at 6000 psi.
Good luck

Yes, you will indeed raise the pressure to 6000 PSI, Its going to be P + P= 3000 +3000=6000
DO NOT DO THIS AS YOU WILL EXPLODE THE HOSE ON THE FINAL PUMP AND WILL BLOW OUT THE 2ND PUMP.
You will have zero effect on the first pump and hoses.
Just to show you this is factual and correct what I am telling you here. For example, an ordinary booster pump that supplies sprinklers in the yard takes city water which is about 50PSI and raises it to about 120 PSI. If you take a look at the pump curve for that pump it will only have capability to rasise pressure say to 70 PSI. So it is additive for sure.
And if you took that pump and put it in a pond where you had ZERO intake pressure, and not 50 as the city supplies, it would only raise it to 70 PSI.

It will still be 3000psi. double the flow(provided the output hose is larger too)otherwise you are restricted by that size and the size of the nozzle.
