Official: Masterflex Calcium Reactor Setup Thread

Is there an updated list of which model type is best the ones listed at the beginning I can't find and the thread was started in 2014


I haven't been keeping track but will try to give my ColeParmer guy a call and see if he can provide me with a list of all part numbers that fit our criteria.
 
slief, tkeracer619 Thank you for your answers. Excuse me, I use it in a calcium reactor. Now at least I know it's not defective. And yes, by RPM it is the best option although there are others like using the OTHER SIZE settings, or actually using another size of tubing like # 16. But now and as long as the 5 feet I buy from tubing # 17 lasts I'll use the RPM mode. Again, thank you very much for your answers and help.
Regards
 
Will this work for a Calcium reactor? Masterflex L/S Console Drive 7521-40 6-600 RPM w/ 2 heads

Yes, it's not a brushless unit so it can be a little noisy. Not an issue if in a fish room.

The head part numbers are important though, ideally you want ones that are compatible with LS17 tubing.

Edit: The one in the for sale forum? Yes, the drive and pump heads will work

Issues with M/F model 7551-00. Anybody know how to clear out error code 11? Pressing buttons won't do anything but beep. TIA

According to the manual, the input voltage is either too low or the board has an issue. Pressing any key should clear the error if the issue is corrected. My suggestion would be to check the wall power voltage to make sure you are providing 110v to it and not lower. If all else fails, contact Cole Parmer support if you can't resolve it.

Thanks, I'll contact cole parmer since I can't clear it with other outlets.

Since there is going to be some down time on my pump. I was thinking of picking up the Kamoer FX-STP. Would any body know the conversion from LS 17 which I think is 1/4 to 1/8th which is on the FX? I really don't want to pickup something that I would max or can't handle it. I was running it at about 54 mil p/m.

I picked up a master flex 7550-60 so I can tune my reactor better. The 7550 is replacing a 7520-00. The old ones start up when power is applied. Then 7550 requires me to press the start button. I remember reading about an auto start feature for the pump. I just can't find it now. Does anyone know how to turn on the auto start feature so it picks up where it left off and continues to run after the power is cut to it?

The Kamoer can be set in ml/min and maxes out at around 120ml/min so you’d be fine for the time being and have an OK backup pump once you get your Masterflex fixed. I think there is a 3 roller head you can get for it which increases the output but there wouldn’t be any need for that at your flow rate except to reduce the stress on the motor and increase the tubing longevity a bit. I think that head is only available from overseas though. While the Kamoer’s are OK pumps, the Masterflex pumps are far better IMO despite the issue you had. But like I said, have a Kamoer as a backup wouldn't be a bad thing.

There is a manual posted online, I tried to read through it but was pretty distracted by the baby so I may have missed it. I didn't see an auto start function and the insert for the manual (that likely has the pinout for the plug on the back) wasn't in it. I'm sure there is a way to do it, but will take some digging.

Yea. I got a new masterflex because I don't like how it doesn't have the auto start feature. I wonder if I figured out the pin out then hooked it to apex, would it then auto start after power failures? Would I have to program the doseage in apex then?

Also why is it preferred to get a 10-600rpm vs the 0-100 rpm. 100 rpm with ls17 is 283ml/hr. Most of use aren't approaching half of that.

Because the gears on the 600 RPM motor reduce the speed on the motor 6x which means substantially less wear and tear on the motor resulting in increased longevity on the motor itself.

Also even the brushless 100 rpm models can be fairly noisy at realistic operating speeds vs the 600 rpm ones. But yeah, bigger motor ran slower will be more silent and last longer than a smaller motor run faster

That makes sense. One of these days I'm going to get a pair of the right masterflex pumps......

Right now I have 2x 7520-00 a 7550-30 and a 7523-30.

Leaks

Leaks

Every few weeks now my tubing springs a leak. This didn't used to happen.

Anyone know the cause or the fix?

It's LS17 tubing. I am . out of town (of course) and don't have the pump model but it's not the brushless.

It would have to be something wrong with your head or you are using the clear tubing at higher speeds and it’s eating the tubing up in which case, you could try the pharmed stuff. Or if you have adjustable occlusions, maybe they aren’t adjusted properly.
