Operating Principles

Peristaltic pumps work by running a tube through a series of rollers. These rollers press against the tube, forcing air out of it and creating a vacuum that draws in liquid for sampling or purging. The faster the rollers turn, the greater volume of liquid is pumped out. Peristaltic pumps deliver continuous, trouble-free operation, making them especially useful for purging VOCs and other contaminants.

Pros and Cons of Peristaltic Pumps

The two main advantages of peristaltic pumps are their ability to pump a continuous flow of liquid and their ease of sterilization. A peristaltic pump can effectively be left alone to do its job, requiring little maintenance or upkeep during the pumping process. Peristaltic pumps are especially easy to sterilize as, unlike other devices, the liquid being pumped through only comes in contact with the tubing. Aside from regular maintenance, such as cleaning the pump valves, no additional work beyond changing the tubing is required to prepare a peristaltic pump for deployment. Peristaltic pumps are not for every job, however. They operate most effectively at low pressures, making them unsuitable for deep water well sampling. Additionally, they are not as precise as other pumps and cannot be counted on to deliver a smooth flow, particularly when operating at lower flow rates.
