No contamination. Because the only part of the pump in contact with the fluid being pumped is the interior of the tube, it is easy to sterilize and clean the inside surfaces of the pump.

They are able to handle slurries, viscous, shear-sensitive and aggressive fluids.

Pump design prevents backflow and syphoning without valves.
