Okay so enough about buying the dang thing, lets talk about what I got (since I did at least get one!)
http://www.pumpagents.com/GormanRuppPumps/30600-112.html
This is a Gorman Rupp 30600-112 which operates at 120v and spins at 60RPM through it's dual gorman branded heads. I have not yet had a chance to hook it up, as it does not come wired for an outlet, I will remedy that situation as soon as feasible, test, and report back.

Just thought IDE throw this out there for everyone (not just stenner pump guys) that these weighted strainers (which I'm sure you can get separate if you don't have a stenner) work really well at holding the RO tubes down underwater even in high flow sump areas and mixing bins. Having a tube come out of the water could be disastrous if Unnoticed for sometime. I was also worried that the weight would be some kind heavy metal that could corrode but it's ceramic, no worries there.

Awesome news Chris! I'm glad I won the Stenner pump from FMAS.
Yea man me too!!! Your gonna love it!!!

AquamanE- I don't think we've ever met, maybe at macna really quickly but defiantly never at a poker run lol. As per the little black box it's a stenner flow meter to make sure when the pump is running it's actually pumping salt water and not air. It's a visual safety for me.
Ones on the out from the clean salt water bin b4 it gets to the pump and the other is on the dirty salt water suction from the tank line in the stand
I could have sworn the guy in the white porche introduced himself as Chris something., LOL.
Neat gadget btw, and good idea. Ill consider getting a few.
60 rpm will be perfectly slow for AWC. Assuming it is roughly 1/4" line with an 1/8" inner diameter I'd expect you will get less than 1 gallon per hour probably in the 1/4 to 1/2 gallon range, So easily ran on and calibrated with a lamp timer if nothing else!
I'll be very interested in how much noise it makes, or hopefully doesn't make
I made the poor man's version with a spare jaco fitting, a piece of drilled up PVC some nylon mesh netting (old filter bag), zip ties and a rock, :lolspin: not as pretty but who'll ever see it?
So on the topic of speed control...the day after i fried my relays I received the pwm motor control. Its noticeably slower when hooked up, even at full speed. Is everyone else seeing that too? I think that that setting will quiet it down enough to not be bothersome. Just curious if there was a way to get to real speed with it hooked up. I guess I could use one of my relays to create a bypass
Could just be the motor control you have. Mine runs full speed with the control (tested with water volumes to confirm the settings, and it's pretty linear. Half turn of the knob is half speed and half the water moved.
Probably just a pot that is very wide tolerance (maybe even +/-20% if it's a really cheap one). they mostly use 10kohm pot. So maybe the pot on your motor control only goes to 8 or 9kohm, not letting it go to full duty cycle. No big deal though if you will be turning the speed down to quiet it anyway. I settled on about 1/3 speed for my ametek to make it quiet enough not to hear thru the floor where I have it mounted.
these are the ones I've used, both work to full speed or barely a crawl.

Go for it Red_Ant- Its the best thing ive done to my tank in a long time. Now I have more time to sit back and watch it, move things around, clean other things like pumps anf powerheads, etc..... I monitor my alk and SG weekly, and its steady as a rock.

AquamanE I'm running into issues where the new water is filling quicker then the old one is taking out. I have a hunch it might be a kink in the line but not sure yet. Any ideas please advise

Chris- Havent heard this from anyone else. If you suspect a kinked line check it out ASAP.
I good way to test whats coming right out of the line is to cut 2 pieces of line and attach to the outputs of each head a foot or two of line should suffice. Turn pump on for a while and measure. It should be the same. If its not then the issue is downstream.

Good idea I'll try that
Hey Chris, the tubes might need adjustment. Sometimes when they are installed, the tube set anyways, one could easily get more stretched then the other. My method of "adjusting" the tube set was by pulling the one that was out putting more. This takes away slack on the line.
That's how I did it with the masterflex set up. No matter what anyone says, heads will run the same but the tubes will always need to be adjusted.
