You did not provide any information about the motor so we can't tell you where to find parts. The motor is likely made by someone other than the pump manufacturer. If you can find the motor's manufacturer/brand and a model number you can look online for parts. If you do find motor parts available to that level you should also buy a lottery ticket because it's your lucky day. Most.

I did attach more details regarding the motor, please see the new images.
If this part (the disk from centrifugal start switch) cannot be find, is it any way I can fix that by glue? It looks the disk push the contacts for the start on one side only. Wondering if I can glue some layer on the other side. Thanks for any answer.

I don't think the disc will survive for long if it's glued. The centrifugal force will put a lot of strain on it. Add in the heat and vibration and I wouldn't trust it for long. It probably would work without gluing that piece back but you might have a out of balance vibration.

That's a tracking surface and needs to be 100% smooth.
I don't see a way of fixing it effectively/reliably.

You might be able to get parts from the current manufacturer.... Nidec - US Motors

It's a shame there isn't a dimensioned drawing for that part so you can check the bore size to see if it will fit the shaft of your motor.

I did chat the guys and they did measure for me and it fits well. I agree with you the drawing is a must

@Pilot Dane

Part was shipped and replaced and all working as charm.
As per your suggestion, I did buy a lottery ticket the day I found the part. And I di win $20

@Pilot Dane, do you have any other suggestion?
