DPeterson3 I’ve used a shop up in the Pacific Northwest to overhaul Alfa pumps. Complete rework, sometimes with new impellers as well as bearing/seal assemblies were about $105 each.

Gordon Raymond The incased bearing assembly disappeared about a year ago from the "new-old-stock" sources.
I used my last of those about then. I discussed with some other rebuilders what they used, and it develops that Alfa, like Ferrari with other items used a slight variation of a known, durable assembly for the bearing. The source is from an American farm tractor, and the available bearing assembly has a main shaft that's too long and needs to be correctly shortened on a lathe with a cut off wheel. The hardened bearing carrier lacks the hole for original grease install, and the hole is also used to locate the bearing in the pump body with a grub screw.As the housing is hardened, one can grind a notch in the correct location. Finally, the shaft, though hardened, is just slightly undersized for the correct hydraulic press interference fit. This can be addressed with various aerobic stud&bearing mount products from Loctite. Pictures below.
The water stop seal, originally brass bodied is available with a stainless steel body and slightly less robust multi piece carbon seal replacing the one piece original carbon, from Centerline USA and most likely OK parts and engineering in Germany. The sometimes also carry the impeller, thougb originals water stop surface can be re-created with a stainless steel washer but must be cut to impeller original thickness for correct water stop spring pre-load. The lack of the correct bearing carrier and shaft makes pump restoration today more costly and time consuming that a few years ago.

I am looking especially for this part. The bearing can't be removed, the shaft has a groove for the bearing balls.
So if you know, or have something...
I have some NOS spare parts, which include impellers and other water pump parts.
