Abstract

A peristaltic pump and its electric motor are mounted in a common cylindrical casing (1) with an end cap (2). A flexible tube (14) is pressed against the internal surface of the housing by four rollers (13, 18). The three rollers are dumb-bell shaped with a central circumferential groove so that they do not deform the flexible tube. The roller is cylindrical but made of a plastic, e.g. Delrin (RTM) which is only slightly flexible. The four rollers are driven by friction from the motor shaft (8) so that they roll over the flexible tube. A section of the tube is compressed by the cylindrical roller and this compresses zone rotates with the roller (13) to create the peristaltic action.
