Will a 950gph mag drive pondmaster pump create enough pressure to run a Hydrologic Stealth RO 100?

Looks like you have about a 13-15 gallon rez. I use a 750 on my 40 gallon rez with a chiller 15 hose feet from the rez and have no problems maintaining 63-65F. How many tubs are you going to run?I had a little giant hooked straight to the system. Gave me around 15psi. Tested the clean "RO" water and it was @ 115 ppm, same ppm with the waste water. Do I need to hit a higher psi for the membrane to seperate particles properly?
I also replaced the lower sediment and carbon filter.
Would the upper membrane cause this from being clogged?View attachment 954097
My well pump cuts out at about 42psi and city water I think is in the 55psi range.How many psi is a typical garden hose? hooked it straight up to that and still nothing. I need to produce 32 gallons of RO water every 10 days. I'm going to slow down the pressure and see if that lowers ppm. I'll report back with results.
I never thought of the power going out...any good links for a backup UPS?

I think you either have a intercoursed up RO system or it's not hooked up right. It should give you low ppm at just about any pressure. My well water pumps thru it fine, just not much water without a pump on it. Is the membrane installed correctly?
I'm 100% investing in one of these. Thanks for the link!These are the ones i use. I have 5 of them for different reasons. Summers are a beating with their "brown-outs".

Good Luck & Happy Growing
I just need.to find the time to set it up again. I have a valve for the little giant to slow down the pressure. I would love to dial in the RO for the general hydro waterfarm. I have a feeling it might be the membraneYou might still give it a shot before you buy a pump. If it does not work then you might only need something like a 250-500gph. Keep in mind, that no matter what pump you buy, the suggested processing output flow for that unit is 12 gallons per hour. If you want to use a high volume pump, make sure you put a valve of some sort in-line so that you can shut the flow down to the recommended input pressure range (check their website for that model). A cheap valve will save the membrane of your expensive high quality RO filter.
Cheers!!
I fully agree, even at a high pressure it should still read psi. Colour coded so it's pretty straight forward. The new pressure gauge is a bigger thred size so that will have to wait.

I may mention I have a different RO system but the principles are the same for any RO system.
Double check your 4way valve plumbing. They are easy to hook up incorrectly.I fully agree, even at a high pressure it should still read psi. Colour coded so it's pretty straight forward. The new pressure gauge is a bigger thred size so that will have to wait. Here's some pics of unit
Not sure why you'd want to slow it down. I have a pump designed for an RO system and the output pressure to the membrane is 85psi.
You beat me to it. And agree that a pond pump won't give give him the pressure he's looking for.GPH and PSI are like horsepower and torque. Flow rate is not indicative of pressure. No way is that submersible pump going to supply enough pressure to feed that system adequately. I believe optimal for the hydrologic is 40-60 PSI. If the problem is low pressure, consider a demand/delivery pump.
