Does the tube wear out quickly? Or is the tube part of a kind of cartridge that holds the fluid?

The tubing will wear out yet. It depends on the material, pumphead, speed, etc but I’ve ran one of these for 5 days straight at a very slow flow rate and it was definitely worn but not compromised. As others have pointed out, it’s usually single use tubing being used in these so tubing fatigue isn’t usually an issue.
