Abstract
A peristaltic pump for dispensing liquid is described and includes a front housing and a rear housing snap-fitted together to define a chamber having a recessed area and a rotor confined therein, a plurality of rollers mounted in the rotor, and a flexible tube compressed at equally spaced intervals by the plurality of rollers. The rotor undergoes a gradual increase in torque as a benefit of the recessed area, rather than an immediate high-torque load at the start of each pump cycle. Further, 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.
