ABSTRACT:
A peristaltic pump (10) having two side-by-side mounted pump cells (11 and 12). Each pump cell includes a plurality of rollers (16) that contact an array of hoses (19 and 21) to urge fluid substances through said hoses in a peristaltic pumping action. A drive unit (24) causes the operable rotation of the first pump cell (11), and geared interaction between the two cells causes the second pump cell (12) to operably rotate. The gears (13) include nylon bearing surfaces (32) for the rollers (16).
