I too have found the Goulds multi-stage pumps online. What I cant figure out is how to get the PSI output info. Even visiting their website I cannot find the specs I am looking for. But you are right, several large commercial units have these style pumps have them so I assume they are capable of achieving high PSI (with a price tag). Let me know if you had better luck finding those numbers

Glad to help out, I'm no expert by any means, but I try really hard to learn a much as possible by both reading and doing.
I blew up my Procon last year the second time I used it. My RO came as a single post with a Honda Gas 5 hp and a piston pump. I put a 1 1/2 hp Leeson and the procon 330, added another vessel and all set right? Well I didn't upgrade the 2 1/2x10" sediment filter. I ran 1200 gallon a sap through it before the element let go and part of it sucked in the pump. I had my hand on the pressure valve, had just finished flushing it, it was back up to about 75 maybe 90 PSI and BAM the second vessel blew the bottom cap off, I was getting showered with concentrate, I got it shut off. I put the lower cap back on, turned it back on and it sounded like gravel in the pump. I went ahead and pumped the last few gallons out of the bulk tank with the feed pump. I was sick to my stomach!! I had just tapped 450 trees and spent another $1k upgrading this RO and it was the 2nd run of the season ( 2 days worth of sap actually). I ordered a new Procon, a new membrane,(turned out when it blew, the permeate tube broke off the bottom), new torque ring for the vessel cap and a 4.5x20 filter housing and 12 filters. Luckily we froze up the next day for about 5 days, so I didn't loose any production. I still need to add HP and LP cut off switches, I don't know if that would have saved it or not, but it' on the list for this year.
I have found the Goulds pump curve graphs several times over the last few years, but haven't had any luck the last few weeks.
If I find em again I'll post a link on here.
