Barnstead D8991 Pump Problem

Date : 7/13/2015
From : Frank

Question

I am reading the pump question posted on 6/15/15 by Stephen I am having the exact same pump problem The power supply bd output to the pump measures 16vdc the pump is labeled 24vdc Is this a normal voltage reading or do I have a bad pump Please email an electronic schematic for this system it would be very helpful I have a model D8991 sn 899981147742 Thank You Frank

Answer

I dont have a wiring schematic for it. I do have this manual :

https://www.apswater.com/manuals/LT899X1_Infinity_UV_UF.pdf.pdf

You have two choices, if you can find a 24 vac supply somewhere, then you can test the pump. If you cant do that you can order a pump and return it as long as it is a good pump. (less freight)

The low voltage makes me think it might be the power supply but I don't have one to test. If you hook up the pump and measure it with the pump running it would be interesting to see if the voltage goes up under load.

Infnitys are old systems that were never very good. There are not a lot of them out there anymore.
