I want to do a small portable unit to move around a lot, see DMW CART AT: TractorByNet.com - Compact Tractor Forum (Re: pressure washer to draw from a tank??
I use a Comet AXD 2520 pump with a 4hp Honda GC engine with no problems ( 2.5 gpm @2000psi). No problems with it drawing the water from the tank. It originally came on a 2 wheel hand cart, but is wasn't practical for my useage. Put it on a small wagon with a 30 gallon tank to make it portable.)

I pretty much want same type of set up 35 gallon tank, but considering use a PREDATOR ENGINE; ( http://www.harborfreight.com/engine...hv-horizontal-shaft-gas-engine-epa-60363.html )
now what would be the right pump (CAT,AR,KARCHER or GENERAL) to use with this engine to pull water through, looking to do 3 vehicles and photos or video will be a big help also looking to have a bypass on pump to recirculate water as to not cause damage to setup
 
I would use a belt drive pump. Belt drives wont give you any problems pulling from a tank. As far as bypassing back to the tank, thats simple. run a line straight off your unloader back to a bulkhead or whatever in the top of the tank. Ive built many of machines. btw id check out a lifan instead of a predator. Home depot carries the lifans as well.

Thanks Ron G any photos or certain model pump to work with Lifans
will I still be able to add engine (Lifan) and Belt driven pump on wagon/cart to a 35 - 65 gallon tank and still be able to do three cars easily?

Yea or you could do a gear box as well. There's a guy here in Louisville ky, Russ Johnson at south side equipment. He can get you the best fit. Gear box would work better for being compact.

Thanks for the info RonG
 
I would consider a used Honda GX over a new predator motor. Just unbolt whatever mounted to motor and atatch pump. Also I would mount a presure washer hose reel to that wagon. Maybe solid rubber tires as the air ones seem to always go flat.

Thanks at STPETEDALE, been thinking hard on a HONDA GX160 just may pull the plug, any suggestions on good cat pump with bypass to hook to the GX160 just bolt pump on fill with gas/oil connect hoses and start working.
 
I like the HONDA engine & COMET pump (self priming) setup used in this video

yea but remember, direct drive may give you problems pulling from a tank. you may have to prime it. Cats are expensive to rebuild. I have one cat that we use and when it craps out we are replacing it. Everything else I have are general pump or udors. We run them hard as well. Theyre all bypassed back to the tanks and have atleast 1 inch feeder lines running to them. They last a while if you do it right.

Is it this simple or more to building, I can get a HONDA ENGINE and A PUMP just bolt it up and it should work?

Russ os GREAT. Southside is one of the best suppliers IMO, and Russ is extremely helpful. I suggest you give him a call and he'll set you right up.

I also recommend the belt drive -- it will not only draw water faster, but it will last 3 times longer, too.

You can get a good 4 GPM beltdrive for around $1000 online.
