    I can’t find any specific info online which just seems weird to me. But from what I gather there ate some capable of pushing 500psi

    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.

    I would love some tips n tricks for adding some pressure switches. Good leads on what kind and best place for putting them? I'm holding off glueing anything till I can get that done.

    I did find them (graph charts) on their website but despite what I thought my reading abilities were I cant seem to distinguish what the operating PSI is, I can see GOM head pressures and such. Maybe I just am that illiterate but something like this is not new to me.

    Im sure you were passing razor blades when you heard that noise. Stemming off the OPs original post, 4 posts with a larger ore filter and a 660 would probably be about right? This is of course if you went the procon route which Im still undecided until I gather more info on the Gould style pumps

    There's several post in the RO forum from a few years ago on what switches and where they go and how to adjust them. I'm currently reading electronics for dummies...again, to try to get up to speed on relays and circuits and what not so I can integrate everything into one box, hopefully. I'm using a 110V Wayne SS pump for a feed pump and my Procon motor is wired 220V so one gets plugged in to one outlet, and has it's own on/off switch, and the other gets plugged in another outlet and I wired a switch on and bolted it on the frame. I know the LP switch goes in between feed pump and filter, and the HP switch should be in between the HP pump and the membranes.
