What is the maximum gpm ?

It's is rated at 3gpm max flow so you'll be good there, I assume the minimum flow to run this machine would be around 2gpm. So if you're running 3.5gpm at the gun with at least 3k psi you'll should be right in the sweet spot for this machine although it may be somewhat large for your machine at 20inches you may want to walk a little slower to mitigate tiger stripes. General rule for surface cleaners is 4 inches per gpm and that would put you around the 15/16inch mark for maximum efficiency for your machine. Hope this helps🤘🏾

Suggested psi for driveways and flatwork is 2,000-2,500 psi that is controlled through the tips. Do the tips with this output that psi?

use mines on a 3000 and a 3600 , works great on both PSI. gets the job done

Does this connect directly to a Simpson 3200?

No, you will have to purchase the connectors.
