Hi, does anyone know if it's possible to replace the motor bearings in
this type of pump?

It started tripping the GFCI when I plug it in, so I took it apart and
I got it to at least run now, but it goes slower and vibrates, then
begins to overheat. Do you think it's possible to fix?

You say you "took it apart", and yet the only image you have to offer is
one of a plastic enclosure.

Unfortunately, my x-ray device for scanning internet pictures is not
working at the time, so I am unable to provide you an answer.

I think this is probably OP's pump.

How long in service? Duty cycle?

IMO doesn't like there is going to be mcuh repair opportunity ... worn
out?

Looking at the PDF in your second link, states there is no lubrication
or meaningful maintenance. Basically says to just clean the impeller.
