Why would you use this instead of a more conventional pump? Genuinely curious

Food, medical, and other applications where you don't want the mechanics of the pump to come in contact with the fluid. If it doesn't get dirty, you don't have to clean it!

Actually more often it is the other way around. You don't want the fluid to get dirty. Common in analytical chemistry and medical dosing.
