As a side note, I got a great deal on a Cole Parmer 7523-80. It's a new style 600 RPM digital brushless pump that was barely used. It was a good enough deal that I couldn't pass it up. This thing is deal silent. I will be replacing my other digital Cole Parmer with this new later today and will put my original one up for sale.

Just wondering what the pump is that you put up for sale?

I just got a 7523-90 on ebay for what I think is a good price - could it have been yours?

Did you pick up the one that had the cracked face? If so, I was eyeballing that thing for a while. I haven't put my pump up for sale yet. It's a Cole Parmer Masterflex unit that bares the Manostat Carter brand name which is also a Cole Parmer company.
This is it.

What a nice piece of gem !

I wonder how you can find this nice stuff out there ?

Such a difficult task here in my Country as Cole Palmer has not been widely used and thus can not easily find in used / 2nd hand market.

SCott That5 Pump is NICEEEEEEEEEEEEEEEEEEE.

Ok Update

I rebuilded the motor pump with new bearing and clean out the gears and then applied new grease.. . Started it up and YES,SHE Lives..... I started hearing a click sound and after talking Slief.I placed a rubber tape to the Pin Head and WOW ,I don't hear a thing... VERY Quite.....

Now to start the CO2 . and Get this Gurlll..Going.....: )


Thank you REEF CENTRAL.. Family....

Awesome! Glad to hear it. Could you post the bearings you ended up using?

My pump has been running a few days now. I have it dialed so the AP doser is doing 1 bubble every 6 or 7 seconds and my pump is running at 70 ml. My ph has leveled out around 6.53 and it appears to be working well!

That pump is a 0-600 RPM pump so at our flow rates, you certainly won't be working the motor hard due to it's gearing. It appears to use the same brushed motors as the other brushed pumps so from a motor standpoint, it looks durable. It also looks very clean and should work reliably for a reactor. It won't be as quiet as a brushless unit and won't be as easy to make very precise adjustments as the digital ones. It also will not be easy to calculate flow assuming you want to know how many mL per minute you are flowing. You will essentially have to count the rotates per minute then do some math based on estimated RPM and the flow per RPM based on the tubing size as opposed to seeing the RPM or mL per minute on a display.

I was wondering how difficult to calibrate the ml/ min, I have seen some member here also have this kind of pumps without the digital display and is this needing to count the rotate or rpm per min and using graduated cylinder or beaker with timer to distinguish or set up the right rpm to give the needed ml/min of which in my case at this moment I needed 15 ml / min.

I may have some difficulty during initial calibration may be this unit is just my temporary stepping stone before I purchase a nice digital unit like yours.

With the analog/dial controlled Cole Parmer, there is no calibration. You essentially have to guess or count the RPM looking at the key slot on the front of the pump head and do the match based on the tubing size. There are charts on the Cole Parmer website for the different heads. You can search for your head in the details for that particular head, there is a flow chart that tells you the flow rates in 1 RPM increments for each tubing size supported by that particular head. From there it takes some quick math. On the digital Cole Parmers, you know exactly what RPM you are at which makes it much more precise. In the end, you can't really assume with a calcium reactor that you will need "x" ml/min. It really boils down to the tanks needs are far as calcium/alk uptake combined with Co2 rate and reactor pH. You get your reactor to a target pH or target effluent alk level and adjust the flow rate to meet the tanks needs while maintaining your target pH level inside the reactor.

Digital display or not, i let the effluent flow into a graduated cylinder while running my iPhone's timer to figure out the ml/min.

At what PSI do you guys get your CO2 tank refilled? I'm at about 400psi right now.

The bottle pressure stays relatively consistent until the liquid co2 is gone. Once the liquid is gone the bottle pressure will drop quickly. Within a day or two. The pressure when full depends on the size of the bottle so if it's lower than normal now is probably a good time to refill.

You can also hold the bottle on its side and turn it on the lengthwise axis. You can feel the liquid co2 slosh sides. They also sell level detectors. I just refill my tank once per 6 months regardless of fill so I don't need to worry.

You get your reactor to a target pH or target effluent alk level and adjust the flow rate to meet the tanks needs while maintaining your target pH level inside the reactor.

Presently with my using ball valve in controlling the effluent rate , it needs 15 ml/min that match my reactor ph @ 6.95 as well as the pressure and seconds per bubbles setting in my AP regulator and this give me a sweet spot of maintaining my alk/ ca / mg supplement to my tanks needs.

So I. Case I bought a analog / dial CP unit , it means that I need to rotate the dial knob of the RPM or speed of the rotation that using a graduated cylinder to hit the right speed or rotation that also give me the 15 ml/ min at the same setting of my reactor and AP regulator?

I got your point that in CP website there is a guidance or chart that will let me easily hit the right RPM based on informations I have over the tube size and correspond to the pumps head model ?

Digital display or not, i let the effluent flow into a graduated cylinder while running my iPhone's timer to figure out the ml/min.

Thanks !
This is also the way I am calibrating my effluent rate even with Ball valve so I also thinking of doing it the same in case I bought a Analog CP unit .

Further to my earlier posting, I am also would like to understand how the flow chart of CP will be with various pumps heads. I believed the flow rate should be directly related to the pump heads use rather than the pump itself , so for example if the pumps head will be model number 7518-10 (the pump model : 7520-20) , I check with CP website and flow rate of 7518-10 as follows;

The specs of 7520-20;

With my very minimal (to none) of my understanding on this peristaltic pump , based on the above flow chart of Model 7518-10 and pump specs of 7520-20 , if I need 15 ml/ min effluent rate , with L/S17 , so which speed I have to be more likely dialed in ?

Should I choose L/S 25 tubing Instead of L/S 17 as The flow chart @ 6 to 600 rpm , flow rates in ML/min at various rpm data gives following range;

L/S 25 - 10 to 1000
L/S 17 - 17 to 1700

Or in case I computed it by using the above flow chart with ML / revolution (rev);

L/S 25 @ 1.7 needs me to turn the dial knob to approx. 8.82 marked or around 9 at the speed control

L/S 17 @ 2.8 needs me to turn the dial knob to approx. 5.35 marked or around 5 at the speed control

I wonder if I make things complicated or should I just simply use graduated cylinder with timer and rotate the speed knob or dial knob until specific rpm or speed give me a 15 ml/ min?

I can also see that the speed knob only range from 0 to 10 speed , so I presume the dialing will be more likely roughly as this is not the same as to the digital with LED display panel to shows their speed or ml in numbers.

I supposed in calcium reactor, we don't have to be exactly or accurately hit the exact ml/min needed, a tolerance of 2 - 5 ml +/- should not be affecting much , right ?!

Hope to have your professional guidance .

Cheers,


MD

You are correct. 15ml/min is about 5.3 rpm with LS17 tubing or 8.8 with LS25.

Questions here;

If you will be giving a choices of same Cole Palmer pumps , which model down below you would like to choose and why;

1) 1.6 to 100 rpm / digital with some distinct sign of wear and tear on the cases model number : 7523-30 , 7524-50 , no idea if this is brushed or brushless

2) 6 to 600 rpm / analog with a nice intact cases and cleaned motor inside model number 7520-20 , brushed pump

All with pumps head model number : 7518-10

Cheers,


MD

 

[tkeracer619]

The 7523-30 has the same internals as the one you already have. It is a brushed unit. 7523-60 is the brushless version of that unit.

Help again.
Ok Today I started the CO2 tank..

1.Calibrated a Brand New PH Probe with 4.00 - 7.00.
2. Plug- in the solenoid , Open up the reg. and turn on the gas tank.
3. lowed the psi to about 20. and the bubble count 1 to every 2 seconds . about ..

The PH started 5.58 and kept going up.. Now its at 6.82 seems like its going up ????

my alk is 7.7 and PH is 8.06

How do i lower the PH ?

I have the Ph connects to my reefer keeper lite.

should i connect the solenoid to the RKL Bar too ?? I have it plug in to a Reg socket .
