Abstract
The invention relates to a peristaltic pump system. The pump system comprises both an insert (10) and a motor assembly (30). The insert essentially comprises a wall (16) and a duct (22) of deformable material. The motor assembly comprises a drive shaft (38), a plate (50) on which rotary means (54, 64) are mounted to guide wheels (48) suitable for co-operating with the duct (22). When the shaft (38) is inserted, the wheels (48) are spread outwards and compress the duct (22) between themselves and the wall (16) of the insert.
