Would a CP Masterflex L/S Rigid PTFE-Tubing Pump Head Model# EW-77390-00 with a Masterflex L/S Digital Drive Model#EW-07522-20 work?

It might but not sure why you would want that head. It's max flow rate is .22ml per rotation using 6mm tubing so at full speed on that 600RPM pump, you would be looking at 132ml/min. While 132 is higher than you would need, you would be running that motor much harder than ideal even for normal operating rates.

That is a great pump and I would stick with a standard LS head that supports LS17 tubing. A head like the 7518-00 or 7518-10.
 
I recently switched from a Reef Octopus reactor to an Aquamax3. I use a Cole Parmer 7523-80 with a 7518-00 head and an Aquarium Plants regulator. My flow rate is 90ml/min. What is the drawback to colled rolled steel rollers?

With the Reef Octopus the reactor ph held very steady but with the Aquamax the ph continuous swings. Not much but a variance of .03-.04 (see attached graph).

The other change was from using ARM media to now a combination of Arm and Newborn.

I know the variance is small but I think it is making more difficult to maintain my tank dKH.



For me the arm media were terrible and won't dissolve correctly. I dumped it and use all reborn media and the pH is very constant.

I agree. I am only using the mix of both because I had 1/2 canister of ARM. I had to really get the ph low for it (ARM) to dissolve.
 
Hi All, I'm about to setup masterflex pump. I have a GEO 618 with AquariumPlant regulator on my son tank. I want know what PSI and SPB setting on the regulator. I read earlier in the post that someone says they set it between at 4-5 PSI and have the reactor PH set at 6.5. What effluent rate should I start with per minute? I like to keep the Alk in the tank around 8.
Appreciated for the help.

Every tank is different. My tank uses 3+ dKH /day and I rum my pump at 110ml/min and reactor ph at 6.45 (currently)

Have you been dosing? If so, what and how much? You can use this cacluator to determine settings to replace dosing.
 
I been using the calcium reactor with a feed pump. The effluent rate is a slow stream but it keeps getting clogged.

Measure the flow rate from the feed pump and set the Masterflex to that and leave the regulator settings alone.
 
Let me take a look tomorrow but I think you're head is fine. Some pump drives require what is called a "long shaft" pump head but I don't have any personal experience with them. If it was working fine before something funky is going on.



Hey Mark you refer to the "œlong shaft" pump head which sounds to me may ne necessary for this 7550-60??

Essentially the play in the fly wheel shown in pics allows belt to slide on the shaft creating just enough distance between the male tab end of the pump head to the female-shaft that it skips
And doesn't turn the tubes. So longer tab on end of pump head may keep
Contact?

Otherwise If i could get a bushing on the shaft to force the shaft closer to the pump head and eliminate the play on belt wheel...any ideas for a bushing?

Ive been running my backup mflex while this 7550-60 is down but still want to fix it!

ALSO I continue to have lid leaks on the reactor- very discouraging- is there reallu that much pressure/ suction created in this system that a normal lid would leak? Im letting the now-westmarine 5200 sealed lid cure before powering up the waterblaster for reactor circulation

Thoughts on bullet proof reactor lids?

How to use APEX to remote control the effluent rate of your CaRx with a MasterFlex Cole-Parmer Pump. I am using Model 7523-60 -10-600RPM with easy Load 2 type 17 tubing.

1. -cut the end off an ethernet cord and strip the orange and blue/white wire
2. -insert the blue/white wire into a DB15 breakout connector (amazon) or directly into the hold. Pin 1 is blue/white (+ speed) pin 3 is (GND).
3. -turn off the masterflex
4. plug in the cable to the APEX port 1 of 0-10V control and other end into the DB15 of the masterflex
5. hold mode while you turn on your masterflex, release when see inP
5. press up/down until see 0-20 then press mode
6. press up/down until see 0-10 then press mode
7. pump will now start based on your apex speed, which is very fast at 100%, now we need to tweak it down for max
8. hold mode while press flow
9. now see LOW press down to your lowest desired speed, now press flow
10. now see HI press up to your highest desired max speed (safety), press start.

You should now be able to go into your apex and bump speed up and down on your variable speed channel 1. You will see the flow rate change on your masterflex as you do so. Now you can adjust your effluent remotlely, and if you also use the ph probe to control your CaRx solenoid, then you have two ways to tweak your alkalinity while on vacation... this of course is in preparation for the release of the TRIDENT if using a CaRx.

*Note, as long as you have a remote control option on your masterflex, you can adapt the pins as found in your manual online.

I just read the manual for the 7522-20 and 7523-80 with wiring diagram for the dm25 is pin1 0-10v pin 3 is ground is anyone is thinking of using the apex to control the masterlex.


Thanks for the info [MENTION=44495]zachtos[/MENTION]

The long shaft is much longer than the normal unit. The cog sticking out of the back of the pump head is about an inch long, give or take. So I don't think that would be it.

What page is your previous post on? I forgot about this, sorry!

That said I have no experience working on belt driven units. Everything to date I've worked on was gear driven.

Just to clarify for those that looked at the pictures compared to what is written. The two wires needed from the Ethernet cable as the Orange/White (orange with white stripe) and the White/Blue (white with blue stripe) The original post has the stripe color first and the main color second (or doesn't have the stripe color in the case of the orange).

Hope that makes it more clear for anyone reading the post and then looking at the pictures.

Thanks zachtos for the work and for posting it.
 
I am setting up a Kalk reactor on my reef. I have a Cole Palmer 7520-00 driver and a 7518-00 head. I am looking to drip Kalk 24/7. I would like to drip approximately 1.5 gallons of kalk a day. I did the math and it looks like I need to use L/S 14 equivalent tubing at a rate of 18 RPM to be in the ball park. Is this an appropriate set up. It will be located in the fish room in the basement so noise isn't a concern. What is a good L/s 14 equivalent tubing for my head? Also, where can i get connectors to go to regular air line hose? Thank you for your help with this.

After this project, I'm moving on the a CaRX!

I really have no idea what is going on here. I have no experience with pumps that have a belt drive system... I don't think a new head will help you solve the issue. Maybe you need to find a brass washer to put in it to take up some slack. Otherwise I think it's time to replace the unit...

One of you guys bought a drive a long time ago with one of those crazy multi cartridge pump heads. Any chance you're following this thread, see this post, and still have it? Long shot... but just checking. Please send me a pm if you do.

Had it, did not work well for cont water change and had sold it expensive on eBay
