Now that someone has mentioned Grundfos, I've got (4) 50 hp (yeah, that's horsepower) multi-stage centrifugal pumps sitting around doing nothing. OK, actually the company has them sitting around doing nothing. We used them to generate ~225 psig @ upwards of 200 gpm. We are looking to sell them if anyone is interested.
Awesome jet-impingement possiblities or great for that touchless carwash system you've been wanting to install in your garage. LOL
