I also read a few other threads on the subject and didn't see much on that. Construction yes, but not much on flow.

Nope. The flow rate is specific to your reactor and tank.
These Masterflex pumps we are using are just replacing whatever cheap feed pump you may have been using before. Same exact flow rate, it's just rock steady with the Masterflex pumps.

Link to Cole Parmer discription of that head. Nope, no LS 17

dennis, I believe I bought the same model you have. I got it brand new for 250 on ebay. Got it in yesterday and turned it on. Very fluid. But it's loud. The pump isn't loud but there's a humming. Is yours like that?

That is not a brushless motor.

Yes, the brushed motors will have a hum that increases in decibel as you increase the speed.

Thanks for the kind words 
. Everyone involved has added to the discussion, it doesn't always go smooth but the community has really come together on this one. I just want to thank you all for being patient and helping others out. The collaboration in this thread is great as well as the communication most of you have. Many people have messaged me and not taken the time to come back to the thread or update it, so for those of you that do :beer: (it's not too late if you haven't 
). Not all has gone smoothly behind the scenes so if you got burned on ebay or I forgot about you I hope you come back to continue progressing the thread with the rest of us.

My AWC and ATO setup.
Awesome!
Ok Here we go . I got the MASTERFLEX L/S COLE-PARMER DIGITAL STANDARD DRIVE 7523-70 PUMP CONTROLLER and then had too purchase a New Cole-Parmer Masterflex Easy-Load II Pump Head Model 77200-62 Cause it didn't come with it..
I Have a MRC Dual Calcium Reactor w/ Blueline 10
Very nice setup! This thing is going to be solid.
Picked this up recently. Will it be OK to use? The head is a little loud though.
Heck yeah it's ok. Made when stuff was built to last!
Is there any way to clean or service it myself without messing up the unit?
Yes, somewhere in here we discuss it but you strip it down, replace the bearings and grease the rollers with a food grade synthetic penetrating grease
Do I have the tubing clamped down right?
Try it with the head off and see if it spins freely. It does look like the tube is stretched too tight. Some of the older drives have a hard time going slow, if the drive runs better at higher speed and you can tolerate the noise you can use a smaller tubing. The reason I recomend the ls17 pharmed bpt tube is at the avg speed for a calcium reactor they are rated at 10,000+ hours. The rep told me a year continuous use. The small tubing would have a shorter but still very acceptable life. I change the tubing quarterly anyways...

:headwally: Let me just say that I am very sorry, it slipped by me, I did in fact recommend Janey buys that stuff... you can toss it in a flat rate and one of us or I will buy it. Most of us use it.
Take the head off and run it. What happens? That doesn't sound healthy but error 3 is usually an obstruction.

Ok Seems like it holding steady I got it running at 15.Also could it be that i didnt have reactor running.. I got it recirculating now and the masterflex is doing its thing..
tkeracer619" Gonna hold on too it. (tubing). If all goes well , Gonna buy another masterflex for my 2nd tank..
I took the head off, which is brand new. Its the Motor where the noise coimg from ..

Is it quiet? These drives have a massive amount of torque. Consider anything with the reactor as a non factor in the peristaltic's operation.
Thin wall tubing is the ls17 (precision). The thicker tubing is performance tubing.

Great to hear. I was checking your calcium reactor thread and didn't see an update so I had been wondering if you got it working. What was the issue with not being able to prime?

Question..
I got home today to find the Masterflex stop and had an error code 3 .
who knows how long its been off . Right now im waiting on the calibration fluid for my PH probe, before i start the CO2 Regulator. Whats happen if this keeps happening with the masterflex stopping , and CO2 running.
Here the sound coming out of the Masterflex . Tell me what you think...

According to the manual, Error 3 means: Triac Angle too large or motor overload. Check all motor connections. Check pump for obstructions. Unit must be turned off to clear error.
This can be caused by any number of things such as:
Gears binding up or dirty
Wrong Tubing
An internal issue with the motor or motor controller.
What tubing are you using? I know we had that discussion. I assume you are using the tubing that came with the pump head and not LS17 tubing? Is your tubing the clear stuff is the beige stuff? Using the wrong tubing would very likely cause this scenario. I don't recall if your head was the one with the adjustment to increase or decrease the roller pressure on the tubing but if its the Adjustable one, it could be that you have the adjustment too tight. If it's not the adjustable head and you are using the tubing that came with the head, the next thing I would do is remove the cover and check the gears.
Take a look at the manual below. While I am not sure it's for your specific model, from an error code standpoint, it is the same. Under mainentance, it will give you insight into the gears and what to look for. The other that it could be is the brushes being worn. While worn brushes would be a long shot, when I got my pump, I ordered a set of brushes and replaced them as soon as I got my pump just to be on the safe side.
First thing I would check is the tubing. Second thing I would do is remove the cover, remove the front plate from the motor and check the gears for wear. The gears are considered a maintenance item. Whether that means you should clean them or simply replace them I am not sure but they do include replacement part numbers. I would definitely inspect them though and clean them. Check the wires going to the motor to make sure they are not loose or burnt looking. Make sure everything else is plugged in well and not loose under the cover.
Another thing you could try as a last ditch thing is changing the flow direction. To do that you would reverse the pump direction and reverse your tubing that goes into and out of the pump. Changing the flow direction is not a fix but it could be a work around for a weak motor.
Here is the manual.

Janey has a brushless drive and iirc the head is non adjustable.
Please run the unit with the pump head removed and see if you get the issue.
Nothing, the ph probe turns off the gas.

Yea, you are correct. I just went back and looked at her original post. 7523-70, is a brushless model and I didn't see the adjuster on the head. Cole Parmer doesn't have the manual listed anymore. The link is no longe valid.

Here is the manual. Error 3 is Overload for this model too. I have a feeling that removing the head will eliminate the issue since there will effectively be no load on the pump. I still wonder about the tubing being used. If it's the correct tubing, then it would have to be something with the head, gears or perhaps a bad motor would be the culprit.
