The problem was that the indexes were not rebuild after purging the records (every month there's a process that deletes any record older than 3 months); once rebuilded, all deadlocks disappeared.
About the use of MERGE, I google it and found that in general gives a better performance than just using INSERT/UPDATE instead so, I think I can let it working as it is (just need to be sure that indexes are rebuilded after the monthly purging).
I will try anyway the usage of parallel processing for it, that may help also,
Thanks everyone!
