A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
The pump of the phacoemulsification system can be a peristaltic type or a vacuum transfer type. In peristaltic pumps aspiration flow rate and vacuum are independent. Vacuum is the suction force which holds cataract nuclear fragments against the phaco tip so that they can be emulsified, and draws the emulsion into the tip. [3]
Diaphragm pumps can also be made which discharge at fairly high pressure. Diaphragm metering pumps are commonly hydraulically driven. Peristaltic pumps use motor-driven rollers to roll along flexible tubing, compressing it to push forward a liquid inside. Although peristaltic pumps can be used to meter at lower pressures, the flexible tubing is ...

A minimum flow protection system ensures that the pump is not operated below the minimum flow rate. The system protects the pump even if it is shut-in or dead-headed, that is, if the discharge line is completely closed. [44] The simplest minimum flow system is a pipe running from the pump discharge line back to the suction line.
The company was founded by Jerry Cole and John Parmer in 1955 and took up shop in a 1,200-square-foot (110 m 2) loft on West Illinois Street in downtown Chicago. [2] In the 1960s, Cole-Parmer acquired Masterflex peristaltic pumps, followed shortly by the purchases of Gilmont Instruments and Manostat Pumps.
