Jebao WP25 replacement impeller end caps

One of my wp20 stopped spinning so I took it apart to clean where the impeller connects to the rubber holder. The ceramic holder wasn't spinning over the impeller so I decided to use a pliers to try to force it off. Seems I used too much pressure and crushed the ceramic piece that the impeller end inserts into. Searched online but I don't really know what the piece is called. I ordered a replacement impeller from fish street a few months back but it didn't come with the end pieces that I broke. Anyone have any ideas of what I might use to replace it or where I can get a new one?
