A peristaltic pump system includes elastomeric pump tubing and a roller pump. The pump tubing has a pumping segment and an inlet segment. The inlet segment has an inlet segment outer diameter. The pumping segment has a pumping segment outer diameter less than the inlet segment outer diameter. The roller pump has a roller assembly and a roller assembly housing. The roller assembly is disposed within the roller assembly housing and engaged with the pumping segment within the roller assembly housing. The roller assembly housing has an inlet gap formed through the roller assembly housing. The inlet gap defines an inlet gap inner diameter smaller than the pumping segment outer diameter. The inlet gap is adapted to frictionally receive the inlet segment for aligning the pump tubing with a roller assembly and mitigate longitudinal movement of the pump tubing into the roller assembly housing. |
