Abstract
A piston pump propels liquid through a lumen of a flexible tube segment. The pump includes a first tube clamping member, a first set of tube squeezing members, a second tube clamping member, a second set of tube squeezing members and a synchronizing arrangement for activating the members in a sequential order such that fluid in the tube is displaced in a downstream direction.
