when you install a Taco or Grundfos pump you have to have flanges on your pipe ends....
are there any solderless way to add these to your copper pipes that really work or is solder the only good way??

All the flanges I have seen are threaded, which means that you would need a thread-to-solder adapter. I suppose you could use a Sharkbite fitting if the temperature rating goes high enough (I don't know if it does) but the cost would be quite high. I just checked and genuine SharkBite fittings ARE approved to 200[SUP]o[/SUP] F. and for hydronic heating systems.

You'll have to solder if you don't have a male adapter on your copper pipes..
