I was given a few KP250's that are shot to tinker with and have pulled them apart, to have a look. My aim is to clean one up and keep it in my class so the kids can see how the pumps work.
When I pulled them apart the first one is dead clean and the motor shaft and bearings are smooth and appear fine. The other had clearly been run dry and overheated so I thought people might appreciate a picture of what running dry does to the inside of these pumps, this one was cooked nicely.
A few months ago the ebara in my septic system was taken out and replaced because the seal was no good. Rather than replace the seal the pump was replaced under warranty. This was because the septic system must be online and as such if a pump is taken out another goes in. Anyway, that is where these pumps come from (septic systems) so I am hoping that the clean pump may just need a new bottom/impeller seal.
Problem is the power cords have been cut so I can't test it, will have to buy a new one

i thought these were the people with the smarts ) with no apparent dammage 
next morning the tea temp was cooked and very warm to the touch. Should have realized that an 1100watt motor = approx 1100watt heater in the tank
