No I am thinking that the impeller is getting damaged by the damaged stator abraising it.

Les what sometimes happens is that the bits of magnet stick in the well of the stator. When a new impellor is installed the magnet makes the metal fragment "stand up" jaming and damaging the new impeller and stator.
Yes/No Les. Fine fragments of the magnet stick to the side and bottom of the stator. Very difficult to remove because they are magnetic and clinging to the nearby metal attraction. When a new magnet is installed these fragments stand up due to the stronger magnetic field of the new magnet and get cause the damage.
In the early 2000's and later in the mid 2000's some reputable brands had a similar issue with impellors. All are resolved today
@Leslie-I agree to opt for a total pump replacement, also, I think a cooling problem could be present, so far I have not heard anyone complain about the heat fatigue with the armature on the internal Skimz using the same pump.
so it jsut not the the one model of pump is all of them ??

might be a stupid question.. when installing your NEW impeller, did you add the bush to the bottom of the shaft before refitting?
Ask TSR for a price on a Shark 3 Sicce pump. Its a reliable pump and has a 1020 l/h air draw. Those Eden pumps are going to keep on breaking and going to cost more in the end.
Skimz have come back to to me and will be sending me a "new" impeller
