Peristaltic Pumps

EPM SeriesPeristaltic Pumps consist of a tube which is squeezed by a set of rollers to move fluid. By constricting the tube and increasing the low-pressure volume, a vacuum is created to pull the liquid into the tube. Once in the pump, the liquid is pushed through by compressing the tube at a number of points in contact with the rollers. The liquid is moved through the tube with each rotating motion. The design of these pumps is either circular or linear. In a peristaltic pump, the flow rate is determined by both the size of the tubing and the pump speed. Larger tubing produces faster flow rates. The compatibility of a peristaltic pump with a certain type of fluid is almost completely dependent on the design of the tubing. This is why, when selecting a peristaltic pump, it is important not to overlook the selection of the pump tubing. There are many factors that should be considered in this selection process such as: chemical compatibility, pressure, temperature, size, life expectancy, and cost. 

Peristaltic pumps are typically classified based on the pressure ratings they obtain. Low pressure peristaltic pumps are laboratory grade pumps designed for low pressure pumping applications such as in IVs and chemical metering. These pumps usually have dry and non-reinforced casings and use rollers to provide the compressed force. High pressure peristaltic pumps are industrial grade pumps designed for high pressure pumping of aggressive sewage and slurries. The casings in these pumps are lined with lubricants to avoid damage from abrasion and friction, as well as to dissipate heat buildup. They use reinforced tubes designed to handle the high pressures.
