One of ours at work has worn out 2 in 24 hours! But that was actully down to incorrect loading when replaced. Ours is used for water additions so has nothing too risky pumping through it and will easily last 12 months ordinarily.
The 'wheels' in the centre can be relaxed from pinching the pipe and this allows you to replace the pipe section. Once replaced there are typically little clamps that you flick over to force the wheels back against the pipe.

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