hi all
buiding new rig.
I'll be using it mostly for power washing cow sheds - dry manure. Sheds are washed once a year, so there is always few bad spots with built up dirt. After farms, will be concrete, tarmac, and general washing. mostly no chemicals - Farmers don't like them here.

max flow is ~10gpm - restricted by water supply in most places. I want get two wands (5gpm each) going most of the time, or one with higher flow for worst places.
I tried few places to hire PW to try out, but 3000 psi 4.2gpm cold water was most i could get here. works ok, but is too slow for contracting i think.
I have diesel engine out of a small van (~50HP), double axel trailor and 250gallon buffer tank.
Picked up few sets i can get (looking at cash limit i have :grin:) and not sure which would be the best for start.

3000psi, 2x 5,5GPM +hot box (AR pumps 2x RK2120 )
3045psi 10,8gpm + hot box (interpump w2141)
3000psi 10,8gpm + hot box (AR pump XWL41,20)
3600psi 9,2GPM cold (interump T2535)

Did anyone had experience with them pumps?.
Also wondering, would be a big difference between 3000psi + hot water and 3600psi cold with the same flow, for cleaning manure.
what do you think about this kind of set up.
 
man sounds like you've got a pretty s***ty job!

dirty work, but rubber waterproof suit does the job. just smell is bad enough.

We started w/ one of these:

We "rented" one from an asphalt company who's fleet we washed. It saved a lot of time and energy! It's easier to clean up while it's dry!

I was thinking about similar tool. It's great for flat surfaces, but difficult enough to use inside cow pins, where is the most of cleaning.
I'm just thinking about surface cleaner like a whirl'a'way with hot water, dirt killers and water brooms.
 
I would say that hot water is a must if you are unable to use chemicals. And if working in tight spots a Dirt Killer nozzle is the way to go as long as the surface can handle it. They are too strong for wood in most cases.
 
I tried dirt killers on timber and rubber mats. Way too strong. I think i will go into 3000psi + hot water, instead of 3600psi cold.
