Dosing pump?

[reefpeeper]

I have had this dosing pump for about 1yr or more and two pumps stopped working. Anybody know if the replacement motors they sell on ebay will work or where to get some?

If the computer has a calibration function, they should. I haven't had to go through this yet though....maybe someone with first hand experience will have more to add.

Pull it apart and make sure it's the motors. Almost all of those units use the same motors which unfortunately are usually the inexpensive Chinese pumps. There are stepper motor pumps that look identical on the outside and even those are pretty inexpensive to replace. But like I said, pull it apart and make sure is the motors and not the board.

One motor power wire came off of it and the other didnt work because board isnt powering enough. Turns but not strong.

Can you check the voltage?
