Abstract
A peristaltic pump for dispensing liquid includes a front casing portion, a rear casing snap-fitted together with the front casing portion, a rotor confined between the front casing portion and the rear casing portion, a plurality of rollers mounted in the rotor, and a flexible tube compressed at equally spaced intervals by the plurality of rollers. The pump is resistant to constant torques and vibrations caused by a machine to which it is attached so that the pump does not become loose and fall apart. In a first embodiment for low torque and low vibration operations, the pump is screwless. In a second embodiment for high torque and high vibration operations, two screws secure a synchronous gear motor to the pump.
