The shaft should be part of the motor and the impeller spins on the shaft. In this case the impeller seized to the shaft and the heat and friction generated softened/melted the plastic seat. The shaft should have teeth to bite into the plastic. In all likelihood the motor is ruined, it seems the plastic is stripped/melted and there would be no way to reseat the shaft.
That would be tough to cover under warranty. For one, the design you show matches the construction from 2012-2016. Also, this sort of damage would typically fall under neglect as it is due to a lack of servicing, it is not caused by a defect, this would not have happened had the pump been serviced prior to starting to seize and could happen to any of our pumps that was allowed to seize. I would be willing to review it, but I would need to get the date code and see everything in person. Typically repair would be purchasing a new motor block 6105.100.
Ok I just pulled up my reciept from premium aquatics - was purchased 7/18/19-
I didn’t catch it before it seized I guess becuase I didn’t notice it till to late - I’m not sure- I didn’t think a pump would need cleaned or have the possibility to seize up that fast- it has been offline for a month probabky and wasn't started up till feb/March—so less then 3 months of use- should I email you or what best communication?
Please send in the pump with a copy of the receipt. In most cases the pump should be cleaned every 4-6 months, if calcium or buffer is dosed near the pump or Calcium/KH run higher than normal or with low Mg or you have a precipitation reaction, they may need cleaning in half that time.
