Interesting find on those Stenner SVP's! please post your thoughts when you have it installed. US Water Systems has a sale on now, and they are 30-40% off retail.

The stenner pumps seem pretty affordable . Especially the dual head classic. But the question I have is are they as good as the Masterflex? Reliability wise? I've been on the eBay hunt for a Masterflex and came close to winning a few but haven't scored yet =(..
On another note tkeracer619 have you used or heard of anyone using a industrial diaphragm pump for a calcium reactor feed? I have a brand new adjustable prominent brand diaphragm pump for dosing chemicals like ammonia and fluoride in treatment plants in my garage.. It's fully adjustable and really accurate it's just noisy on the pump strokes.. But since it will be remote it may just work in my situation.. Do you think that would be feasible to use? Or should I sell it to fund a Masterflex =) retail on it is 2k+ fwiw. If this derails the thread too much I apologize..

Well, before I took my 7520-25 offline to be replaced with the new pump it started squeaking again. Since I'm intending to sell it here on RC I want to make sure the person receiving it will have it ready to go, without squeaking! Also, this is good hand-on experience for me since I plan on refurbing these pumps as time goes on.
I contacted coleparmer again (Product Applications Specialist Jose Morales) and since I already replaced the brushes and caps our last option is a service kit, which includes gear assembly (nylon gear/ shaft), gear case cover gasket, replacement fuse, and instructions. What I find strange is that it ran flawlessly for about a month before starting to squeak again. I feel like the brushes are far too new to be the problem, right?? Before going ahead with the order I just want to pick your brains here again, thanks for all the help.

What happens if you pull the gearset out and just let the motor run by itself?

So far I do not regret my purchase despite these disappointments. If you want a new pump I don't know of a better option. |

Correction, the Stenner SVP is pulsed below 30% volume. Which in my case is about 2 drops per second. I may be forced to drop into the pulsed range. Or keep the Ph slightly higher.

I wouldn't worry about the pulsing. It shouldn't effect your setup at all. I am definitely interested in your results!
I've been working on something in my super secret laboratory. In due time my friends but for now off the shelf units will have to do.

Aquarium Plants Regulator
An observation I made today is that despite the apparent accuracy of the Aq Plants electronic C02 regulator, it has limitations. If the ambient temp raises the Co2 tank pressure, even though the second stage of the regulator may remain fixed, my bubble rate went nuts. The bubble rate is also highly dependent on reactor pressure (or vacuum). So despite having a dosing pump keeping my effluent feed rate constant, the reactor Ph is not as stable as you might hope. My Apex and Ph probe keep it in range, but the dream of a stable Co2 flow and reactor Ph level remain out of reach. The Aquarium Plants setup is pretty nice, but I find the actual Co2 regulator they sell a bit cheap. The electronic part does add a level of control, but since the bubble size cannot be maintained at a stable condition you still have an uncontrolled variable. I think actually a better quality regulator would do you more good than the electronic valve. Possibly the ultimate is the Aq Plants electronic valve with a different, and better quality regulator.

Again, I think you have a defective regulator because the bubble rate is absolutely not tied to pressure.

Has anyone ran a Masterflex 77410, series pump? its a brushless model that just doesn't have the digital control of the L/S series, actually it is an I/P series and is much larger then the L/S.
I'm asking this as I am totally hooked on my 7523-60 for my calcium reactor and was looking for something that would be similarly silent, but would give me a greater flow in order to power a Lanthanum Chloride reactor. |

I haven't used one like that but I see no reason to believe it is any different other than a 1/3hp vs 1/10hp.
You might want to give CP a call but the drive looks awesome. Keep in mind you can stack multiple heads on these pumps and while not ideal you can easily add flow by doing so. Glad you like the 7523-60. Great pumps!

I am pretty sure I discuss in the very first post on this thread the variances with single stage regulators however if this is setup properly you should have no reason to actively control the regulator with a controller and doing so can effect the overall stability of the system. There is nothing wrong with letting the controller do the ph control. The reactor will still be more stable than without the peristaltic but will not be as stable as one setup as this thread intended. I've been running this setup for years and have set it up on many peoples tanks as well as converted many people here on rc. I wanted to make sure I wasn't just throwing this out there given the costs associated with the setup. Part of the reason I made this thread was to divert some of my 1on1 assistance to the community so that everyone could become more informed. This is mostly what happened. More and more people are switching to this setup and afaik nobody who has gone through with it and taken the time to troubleshoot have had issues. Many have gone from complete non working systems to fully stable systems in less than a handful of adjustments. I probably get double the PMs now and keep them coming! I don't mind but please be patient and if I don't respond immediately it isn't personal, I am likely just trying to keep your pm marked as unread so that when I do have the time to help I will easily be able to find it (I get a lot of PMs). Also, if you have slipped through the cracks and you think I forgot about you, send me another PM! You cannot aggravate me by trying to remind me I am supposed to be helping you!!

Just bought this pump off eBay. Now the question is, what exact tubing and from where should I buy it from? It does not take the LS17. Should I run it with LS15 tubing or return it and buy a pump head that accepts LS17 tubing. Running a geo reactor with AP reg.

LS Performance Tubing
Anything with a 3/32" wall thickness will work in your pump head. The trick is finding one that will last and that is affordable.
Pharmed BPT, A-60-F*, and E-LFL are the long lasting Tygon tubing I would recommend for our application. They are rated for 800-1000 hrs at 600rpm and will not leach anything. AFAIK E-LFL is the only extended life tubing from Tygon that comes with a 3/32 wall thickness and is good for our tanks. If someone knows another source please chime in. The reason I usually recommend the Pharmed BPT first... Quote:

How often do you change your tubing? I am using Pharmed BPT NSF-51, L 17.

The chart shows testing done at 600rpm. Most of us are at about 50rpm +-20. If all things are equal and wear is per revolution that would be something like 492 days at 50rpm. I change mine every 3 or so months and have never had a tube rupture.

they state over 5000 hours for 50 rpm and I think that is where they stopped running the test. http://www.masterflex.com/TechLibraryArticle/773 |
