Mobile Van Water Tank...i forgot something

Sooo... a gas pressure washer (say, 6.0HP) doesn't need an electric primer pump to draw water from a tank without the help of gravity? Such as a skid or trailer mounted tank and pw?

Anyone? I've been trying to research this, and can't find a definitive answer. I'm planning to build a very basic mobile wash trailer this year, and have been wondering whether I need to plan for a primer pump. I intend to use a Honda GX160 (5.5hp) as the motor for the pressure washer, with a direct drive pump. The engine will be mounted on the trailer along with the water tank. Will I need an electric pump to feed the motor/pressure pump?

Gas powered PWs don't need a pump only electric ones.
You don't have to elevate your tank either.

For some reason im thinking the Karcher is self priming and doesn't need a pre pump. However, lets just say the pump wants a minimum of 20 psi from the tank, with very little water in it, it would have to be elevated 20 feet above the PW to achieve that kind of pressure..
I think volume will always be more important than the pressure in this case (just use a flex line or something that will not collapse if the pressure washer pulls a vacuum on the tank).

I use a flotek 3gpm 12 volt electric pump. wired to the van battery with a switch.
it puts out almost 3 gpm and runs 50psi.
I do not have a long hose for my pressure washer so i take it out of the van and have a 50 foot garden hose on a spool. i can put water wherever i need it.

Think about sheeting the car when you are done, it cannot be done with a pressure washer and it cannot be done without a lift pump.
Any videos/photos of your setup available?
 
I had a gas powered honda with a CAT pump fed by a 100 gallon tank and I did not need anything other than the pressure washer itself and it worked great.

HUMP
 
I have a troybilt pw ,vertical pump,and with a honda motor . It hooked up to a 100 gallon tank and works fine off of just gravity . Now if I can find away to keep the water from freezing up at night. I would be mych better.

That one should work. There is a lot of info & questions/answers about this topic on northern tool. Just go into their pressure washer section & lookup the pressure washer you are looking at & you will get a lot of info on it.

Thank you for choosing Northern Tool. A representative will be with you shortly.
Hi, my name is Derek. I am a Northern Tool + Equipment Sales Specialist. How may I help you today?
John: is it true all gas pressure washer can pull water from a portable tank?
Derek: Hi John, I would be happy to help you with that. One moment please.
John: ok Derek
Derek: That is not correct, that would depend on the pump that is on the pressure washer. All of our pressure washer needs to have water forced to the pump before it goes through it.
John: tank
Derek: Is there anything else I can help you with today?
John: ok thanks
Derek: Enjoy the rest of your day!

hi what type of filter system is that?
 
this pump is 120v - they do make 12v also . I choose the 120v as I use this out of garage in apartment or use my generator if mobilized . I guess 12v would work too but I did not want to worry about battery usage and charging ..... . the pressure washer I use does not pull standing water . some do - so the pump is need to supply the pressure washer from the tank , or if I don't use the pressure washer it supplies water almost as good as coming out the spigot . the filter is a single cr spotless .
 
Just as a side note here I talked to one of the true experts in the pressure washer industry and he told me that the idea of a "self-priming" is really a myth. Very few non commercial grade extremely high end gas pressure washers can pull from standing water.

If you are needing sufficient water pressure, a pump will be needed out a mobile water source.
