Howdy,
I have a Schaefer e-series 20 gpm submersible pump in my home septic system. Hopefully even though this says it's a well forum, someone here can give me some good advice.
This pump has been installed about 4 years, and it recently quit working. I decided to take it apart to see if there was anything wrong that I might be able to fix. Need suggestions on how to diagnose the problem. The problem is the motor end of the assembly... the pump end turns freely.
Here's a picture of what it looked like when I pulled it out... looks like it overheated, but it's been underwater so I don't know what the discoloration is from.
This is a picture of when I had it out for replacing one of the level floats in April... note the discoloration. I assume it has something to do with being in a septic tank...
I killed the breaker, and pulled it, which probably took 20 minutes. It was still warm when I first pulled it out (even though it had been submerged). I was out of town when my wife first reported the problem, and it probably sat 2 days with the power on and just locked up.
When I disassembled it, I didn't find anything noticeably wrong. The rotor had a light coating of rust, so I took some 1200 grade wet or dry sandpaper and smoothed out the slight roughness. When I put it back together, everything spins freely. I apply power and it runs for about 15-20 seconds, then locks up. I'm running it submerged in a bucket of water to keep it cool, but it still feels warm when I take it out. I know a motor gets warm when it's running, so maybe that's just normal.
I tried lubricating it, but that didn't help. I've googled it and cannot find any sort of exploded view diagrams of the pump, or service parts lists. Here's the detailed info:
Appreciate any help you folks might be able to give me.
