A peristaltic pump comprising an outer casing, an annular cage centrally in said casing, cage mounting means mouting said cage for rotation in said casing, an annular array of rollers carried by said cage for planetary motion rotating with said cage and relative to said cage, said rollers being dimensioned to project both radially inwardly of and outwardly beyond said cage, a rotary drive in said cage in driving engagement with said rollers for rotating the latter in said planetary motion, drive mounting means mounting said drive in said cage, and flexible tubing interposed between said casing and rollers for peristaltic squeezing of said tubing by successive rollers upon said planetary motion, said casing having an internal sector formation for receiving said flexible tubing, said casing having through openings at opposite ends of said formation for passing spaced locations of said tubing through said casing, and said casing having a through slot along said sector formation for lateral insertion and withdrawal of said tube into and out of said formation and openings.
