which pump for DIY

[xoddah]

i am a new construction cleanup (12 years) ((among other things)) guy

i have a sandblaster i use occasionally, clemco 600cfm run by a 671 detroit diesel i have the skills and knowledge to mount a wash pump on the accessory drive of the engine i know all about drive ratios, gear and pulley requirements

my question is,, because i have about 80 horsepower at the drive, which pump and set up would be the best, for ... new concrete wash, masonary clean
and run a large surface cleaner to remove concrete powder after honing with a polisher wet flour consistancy lots of it ... 7000 psi 12 gpm or 4000 4 gpm

also i have a hot box, diesel burner removed from a large steam cleaner
for the moment i don't see a need for this, however as long as it will fit on the truck i may as well use it HUH ? ?
any advise appreciated

I would suggest going with the AR model XW3025, it is rated at
7.92 GPM @ 3600 PSI, it is an excellent pump. I have one in stock
also could ship it to you today. Call me if interested.

The 4 gpm @ 4000 PSI would be slower cleaning, the 12 gpm @ 7000
PSI would be extreme overkill, plus hoses rated at 7000 PSI working
pressure would be very heavy to drag around and the standard surface
cleaners are only rated up to 8 GPM @ 4000 PSI. [hello]
