Advantages
- 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.
- Low maintenance needs. Their lack of valves, seals and glands makes them comparatively inexpensive to maintain.
- They are able to handle slurries, viscous, shear-sensitive and aggressive fluids.
- Pump design prevents backflow and syphoning without valves.

Famous quotes containing the word advantages:
“Men hear gladly of the power of blood or race. Every body likes to know that his advantages cannot be attributed to air, soil, sea, or to local wealth, as mines and quarries, nor to laws and traditions, nor to fortune, but to superior brain, as it makes the praise more personal to him.”
—Ralph Waldo Emerson (1803–1882)
“... is it not clear that to give to such women as desire it and can devote themselves to literary and scientific pursuits all the advantages enjoyed by men of the same class will lessen essentially the number of thoughtless, idle, vain and frivolous women and thus secure the [sic] society the services of those who now hang as dead weight?”
—Sarah M. Grimke (1792–1873)
“When the manipulations of childhood are a little larceny, they may grow and change with the child into qualities useful and admire in the grown-up world. When they are the futile struggle for love and concern and protection, they may become the warped and ruthless machinations of adults who seek in the advantages of power what they could never win as children.”
—Leontine Young (20th century)
