ABSTRACT:
An improved peristaltic pumping arrangement is disclosed as comprising a housing assembly that is freely mounted on a pump drive shaft, an occludable tubing, a plurality of compression rollers being rotatable by the shaft and capable of compressing the tubing and rotatably driving the tubing and housing assembly a limited extent until the housing assembly strikes a stop assembly for arresting limited rotational movement of the housing assembly and tubing thereby allowing the imparting of sufficient torque to pump the fluid.
