Free bump : although I don't know enough about pumps to really answer your question, I do know that you definitely don't want to tie your well water into any water system in your house carrying city water without approval from the city and any other authorities that have jurisdiction over water, and IF they allow it, they will want it professionally installed with protection devices as well as permits and inspections....
However, if you're using it on a complete separate system, you will be fine.
good luck!
