Official: Masterflex Calcium Reactor Setup Thread

[SkyReef]

My used Masterflex L/S 7523-60, with an easy-load II pump head arrived today. I bought it on eBay for $595.00. Upon turning the device on, the LED display reads "ER 1," which I take to mean Error Code 1. In another post on this thread, another purchaser also had this same error code, and it was suggested there that such an error was an internal problem. I have contacted the seller. However, in the meantime, does anyone know what "ER 1" means and can I fix this problem, or do I need to return it to the seller?

The manual (available on line BTW) doesn't explicitly list error #1 but has an "All other errors" category which states "internal error". Clear by turning off and back on. It that doesn't work, return unit for repair.

Thank you BillFW. I won't be returning it for repair; I will be returning it for a refund.

I have this same model that will not turn on at all.. Looks to be in great condition physically but just no power whatsoever.. Called Cole parmer and they only have a flat rate to fix units
( $600) so I'm hesitant to spend that kinda $ on it.

Have you had to get inside it yet? Know of anyone who does repairs other than Cp? Swapped the fuse and no dice, everything inside looks good visually..

May be time to sell it to someone who can fix it, I bought it from a seller who stated they could not test it as it was missing the fuse as is.. Gambled and lost lol..

You can ship it to me and I can take a look at it. I'd be interested in it depending on what it needs. I run a computer manufacturing business and also do component level repairs so I could probably fix for you or buy it from you. If you are interested, send me a PM and I will get you my address. Once I get it, I will be able to provide and estimate for repair or purchase. It will take me a day to evaluate.

I am finding various versions of 7520. Do they all work for this?

My 7523-60 run for about 5 weeks and it shows error 3 today. I searched the manual, it says motor overload. I tried run it without load and power cycle, still does same thing. Any recommendations?

Since it's a motor overload error and an older unit, I'd take apart the gear box, clean all the gears and remove any of the old great and re-lube the gears. That would be the biggest source of load between the motor and the head. The only other thing it could be would be the bearings inside the motor but before digging that deep, I'd start with the gears.

I think you are right. Just took it apart and it was running without gear and head. Not familiar with grease, is there a special brand or model I shall use? Thank you so much l.

You should use a thick synthetic gear grease.

Scott I have read through this thing....how does one determine what models are appropriate? Every model line has multiple last two digit versions. Did I miss a post detailing the meaning of each?

[vhuang168]

The models listed in the 1st page are what you should look for. There are a few more. It listed but you basically want a model that has the same parameters as the ones listed. The model numbers must be exact.

Are you looking for a brushed or brushless model?

I only rarely see 7523 in any version, but see many 752x-xx. I do not need brushless. I do not necessarily need digital.

Is any 6-600rpm model suitable?

The RPM's are fine but you need to check the Cole Parmer flow chart for the head and tubing you will be using to see what the flow range in terms of ml/min would be. If that meets your needs than the pump is fine. There are many Cole Parmer flow controllable pumps you can choose from, but the correct head needs to work with the tubing you want to use. Most use L-17

My first thought would be Molykote but I would call Cole Parmer and ask them first to see what they say.

That's weird. I've always gotten somebody on the line when I called there and had questions. Their support has always been pretty good.

So I emailed again and they said to not use any grease or lubrication and to send it for service...

If you pump is the 1-100 RPM pump, this is the gear replacement kit for it. The description says it comes with high temp silicone grease.
http://www.masterflex.com/Product/Se...chTerm=7553-08

Based on that, I would say you should be using a high temp silicone grease such as this:
https://www.amazon.com/Dow-Corning-M.../dp/B001VY1EL8

Or there is this gear set on eBay which should also work.

It might work but that stuff doesn't indicate high temp and I think it's fairly thin. The thinner stuff will run off the gears as a result of heat where as high temp stuff will remain where it's needed.

Got a 7524-40 for $100. Looks well used. But head seems pretty new so if the pump too loud can get brushless without head if need to. Hoping this solves different issue I have with different peristaltic feed pump.
