Submersible Motor Snow Cone!

Who can guess right? On why, this Franklin Motor built up with a thick layer of Calcium


Background: Open flow into a pond

Stuck on and overheat?

I've seen wells where the wire was covered with calcium, but not the pipe so I'm going to venture a guess and say it's somehow related to the current

Basically, motors operate with magnetism - magnets draw calcium deposits - therefore the buildup. However, this is a guess!

The next part that puts all of your guesses together: Page 6 of the Franklin Aid manual http://www.franklinwater.com/more/service/aim-manual/motor-application/all-motors/page-6/

• Pump is set in or below screens or perforations

Now you can say it needed a flow sleeve or it just needed to be set just above the perforations for proper cooling (I have also found that the stainless steel shell on the Franklin Motor, will show discoloration from the heat and not have build up).

I will look up the age of this pump to see how long it lasted.

I have a few customers who tried "magnetic" water treatment systems, they said it was a waste of their money.

Same thing happens in an electric water heater. I guess it could be magnetism, but I always thought it was the heat that caused the calcium buildup.

I agree that it was the heat that caused the calcium buildup on the outside of the motor.

I have tons of customers that don't believe in the "magnetic" water treatment but they also thought it was suppose to take out the calcium in the water. The way I understand how it works is that it's as an "electronic magnetic field", that wraps around the house line so it gives the water an "electronic charge", to keep the calcium from building up on your fixtures.

The Franklin Motor has it on the inside of the motor so it's not a N & S pole wrapped around a pipe that has water flowing through it.

Very few customers have said it actually works.

I found this on the web as well https://en.m.wikipedia.org/wiki/Magnetic_water_treatment

The next time I see the drop pipes covered in a layer of calcium, I will post it on here for everyone to see. I see it from time to time because of the static water level dropping while pumping water, it's exposed to the air when this happens, then the pump shuts off and the static water recovers, do this enough times and you will find a layer of calcium on the drop pipes & wire. I would think that the harder your water is and how much you use it, determines how thick the layer can get.

This is a calcium snow cone, but see how little there is on the pipe? The tank T was plugged off as well.

 

[PumpMd]

Wow, how hard is that water and the TDS? Do you think the static water level stays high in the well and what did the pump/motor look like?

The Well Pump was dated 2011, this picture was from 2015.
