Hello,

Does anyone know which of these pins are the positive/negative? The pump that I have is masterflex model WZ1R031. It is a DC pump which means I can put voltage on the correct pins for it to turn.

https://www.ebay.com/itm/Cole-Parmer...wAAMXQ-3NRlStV

Thanks!

So, I take it that the BRS doser isn’t going to work for the calcium rector application. They work for 2 years part time at best. Is there a list of acceptable models of doser? And suprise suprise, I’m looking for the cheapest that will work.

correction - i do not have the pitch, and not quite sure that I could get an accurate measurement.

i found this guide but this requires a bit more precision than I was hoping for.
i counted 85 notches, 4" diameter, and imprinted on the belt is 130XL

I have two 7518-60 pump heads that rattle and also have a sulfur-ish or burning grease smell when running, even on low speed. It's odd, because it seems like the smell is between the 77301-21 brushless motor and the head, so I assumed the motor was the cause. But I ran the motor without head, and there is no smell. Upon further inspection, there is brown residue coming out of the bearings onto the rotor. Not sure if this would just need replacing the bearings, or perhaps the entire shaft and rollers/rotor as well to correct the rattling?

Can anyone refer to the correct size and good brand bearings for replacement?

So I made the mistake of looking at EBay again and saw a deal I couldn't pass up. Brand new 7550-50 with 77200-50 Easy load II head for $140 shipped! It's only 1.6-100 rpm which I know is not exactly what everyone is looking for, but my tank is only 50 gallons. Should be plenty of flow with the Ls17 tubing. Only problem I have now is selling the other unit I have. Any interests? Lol.

What unit are you selling and how much? I am on a super tight budget and tapping off the return is working for me at the moment...... at the moment. Also looking for that deal on a carbondoser.

It will be a millipore xx 80 000 00 (rebranded Masterflex as far as I can tell) with a brand new easy load 7516-10 head. Gonna be a bit before I will be able to sell. Gotta get my new one setup and humming first.

eBay seller totally screwed me over. Purchased and asked a question on the item and today I get a cancellation with the reason stating the product was missing or damaged. What a crock!

Managed a 7550-30 w/ 7016-52 Head for $225 shipped. Seller stated he could not fully test it, so marked it as "for parts only" but it powers on, and will move forward and reverse and looks pretty good overall. Excited to get this in!

Now to search through this thread for the correct tubing and adapters for LS/16 to use with this head.

Could you use these to switch from Ls tubing to 1/4" RO tubing?

https://www.bulkreefsupply.com/mur-l...hose-stem.html

You could this and a coupling. Seems easier than the other connectors that have been mentioned.
