Missing part in Pump?

[AquaJern]

I just bought a used Tunzee wavebox my question is the 6212 pump does it suppose to have a ceramic shaft in the pump because I am use to seeing them on other pumps, but I bought this used ans did nt see it?

No, we use a shaftless design on that pump, it has no shaft at all.
