2.0 - PERISTALTIC PUMP WITH DIGITAL TIMER
2.1 - PERISTALTIC PUMPS OPERATING PRINCIPLES
Peristalsis is a wave of automatic contractions propelling contents along channel or tube, this led to a peristaltic
action. By mechanical simulation of biological peristalsis rollers crush tube walls togheter to form a seal while
roller moves along the tube, then the previously compressed tube regains original form and sucks fluid into the
formed vacuum. The fluid will follow the roller until tube is not compressed any more, then to avoid a flow back
a second roller compress the tube, pushing the fluid out of the pump and repeating the suction action while the
pump continues to operate the rollers which are fitted on a special rotor create suction lift and outlet pressure.
