ABSTRACT:
Peristaltic pump including a housing having a backing plate and an upstanding arcuate wall, a pump shaft mounted in the backing plate, and a rotatable pump head mounted on the shaft and comprising at least one roller means for squeezing a segment of flexible tubing against the arcuate wall to achieve pumping of a liquid through the tubing. The pump head includes a pivotable handle having a recessed portion which cooperates with a ledge in the pump shaft to prevent the pump head from moving upwardly from the shaft when the pump is in operation. Also included are means comprising a roller bearing and clutch assembly for preventing rotation of the pump head in an incorrect or undesired direction during manual operation.
