I now have a brand new Impeller UPGRADE (bought for £173.24 euro's delivered to the UK) and the seals (Part no 10 & 8 in the image) bought separately. I ordered 2 of each seal and the impeller. But my bike has already had the Impeller upgrade, so I do not need to change it now. Silly me, should have stripped it first! So it's for sale as a kit if anyone wants it? Make me an offer.
