How A Peristaltic Pump Operates
Peristalsis is one of the oldest pump designs. Early Greeks used the word peristalsis to describe the operation of a wave of automatic contractions, propelling contents along body tubes to transport food and body waste. Simply substitute with thermoplastic tube and rollers for contraction and we have the peristaltic pump. By mechanical simulation, the tube walls are squeezed together to form a seal as the roller moves along the tube. The previously compressed tube regains original form and sucks fluid/gas into the formed vacuum to create a self-priming function.
