Official: Masterflex Calcium Reactor Setup Thread

Output per RPM based on the tubing and head used is available readily from the cole parmer data sheets for the pump head. and if you cant find it just email or call them. very helpful folks!
 
Here's a photo of my setup.

CP pump is old and pretty basic, but not noisy at all and has the easy bake oven.

Ok, so my drive is still making that noise, even after new brushes! In fact, the new brushes didn't look any different than the old brushes. But every time i mess with it, the noise temporarily goes away. It seems to be coming from somewhere around that metal fan thing that spins off the back of the motor. I tired spraying some silicone lubricant around the fan's shaft/bearings but it didn't do anything.
Any other ideas? It's kind of annoying. ;)
 
Did I ever mention brushless drives? ;)

I assume the brush kit came with new holders? Try a little lithium grease on the brush holder. Not the contact surface but the slides. See if that helps.

Also, the new brushes will take time to seat. If you can look into the brush port and see the commutator it should look smooth. If it has grooves in it you may need to take it apart and clean that up. Brushes are kind of annoying little devils, they can look find but be totally messed up. I am not sure the compound CP uses, it may be too stiff and causes chatter on older less perfect comms.

Give the lithium grease a try and let it run for a week, let us know what happens.

Back in the day when I raced unlimited electric modified RC cars on an oval track we were running 16 cell batteries. Had to turn the comms and replace brushes after every race :lol:. Those thing would hit over 100mph though.
 
Ok, I'll try the grease and check the comm.

You should see the LiPo batteries now.
You can get a Traxxas car that does 100mph out of the box!
My Slash 4x4 does close to 40 on a 2s LiPo. I'm too scared to try anything more than a 3s. :lol:
 
crazy. I stopped probably about 14 years ago, still have a bunch of stuff laying around. The first nitro powered team associated rc10 touring car included. I built the first one, they copied it and made a kit to sell to the public.

I used to build my own engines and motors, won my fair share of some races vs the pros. I was sponsored... Good times. I've been thinking of getting back into choppers but then I remember how that always ended. I also dabbled in throttle exhaust hydroplanes from time to time.
 
Hey guys, I'm having trouble with my calcium reactor and master flex pump. When I clamp down the lever on the head, for some reason I'm having a hard time pumping CO2 to the calcium reactor. I would have to crank up the PSI high just to get any CO2 into the reactor. But once I raised the lever, CO2 flows into the reactor just fine. I'm running the pump at 90 mill per minute.

I checked the lines and nothing seems clogged. So I can't really figure out what's wrong.

Any ideas? Thx!
 
This is a new one.

Are you pushing into the reactor?

How high do you have to turn the regulator?

That would indicate that there is pressure building in the reactor.

What happens if you slow down to say 45ml/min?

What happens if you pull through instead of push?

I have seen a tiny flake of media get into a tube fitting and nothing looks clogged and when you don't flow effluent through it quickly the effluent moves freely. When you try to force a lot of water through the reactor it pushes the media against the fitting and clogs the reactor.

Can you post some pics, it might help catch something odd.

Has this system ran before or are you just trying to set it up for the first time?

i have the masterflex installed at the output of the calcium reactor.

How high do you have to turn the regulator?

before it was set at 8psi. now i have to set it at 9 psi, even at that pressure, the co2 going into the bubble counter is very small. and once i lift the lever, a large amount of co2 will go into the reactor.

That would indicate that there is pressure building in the reactor.

when i remove the checkvalve that goes inbetween the regulator and line that goes to bubble counter, water just shoots out. luckily i have the checkvalve in place!

What happens if you slow down to say 45ml/min?

same thing at 45ml per min. its currently at 40ml

What happens if you pull through instead of push?

pull through instead of push? do you mean having the masterflex right after the manifold and before the reactor?

I have seen a tiny flake of media get into a tube fitting and nothing looks clogged and when you don't flow effluent through it quickly the effluent moves freely. When you try to force a lot of water through the reactor it pushes the media against the fitting and clogs the reactor.

i will try and change out a few more 1/4 inch lines. and see if that will help.

this masterflex has been running for 6 months. i was gone for 3 months. and noticed that there was an issue after i came back.

Sean2sean you mention using a manifold in your setup you aren't feeding the reactor from a return manifold and using the masterflex pump are you? The masterflex should just be pulling water from the sump or display whichever you choose.
 
In line with what TKeracer recommended, I 'll have 2 pumps and digital drives soon. I'm willing to dump the second at cost. If you need one, I'll send it. I paid around 700 for two so you can the second for 350. I may keep them around as a potential backup. Can you remind me what tubing I need TK? Thanks. Jim
 
Did you purchase the easyload 3 I linked you as well?

If so this would be what I would order. This gives you two extra clamps and an extra fitting plus enough tubing for a couple years of operation.

He has a brushless unit for sale for $350 folks. Good units that others here are using.
 
I did, thanks TK
