Most of the macerators are a rubber blade with a cutter housing on one side. If it's fairly old and the rubber blade had a "set" to it, you could have damaged it. Obviously, if it still pumps the same, no damage. Most macerators have a rebuild kit that comes with a new impeller, blade and housing seal.
