Peristaltic Pumps

Portable Sampling Stations

Peristaltic pumps have long been used for groundwater sampling. These pumps have a number of advantages over other types of devices, but they also have limitations.

Although peristaltic pumps are quite easy to use, their application in the field is more limited than other devices. Peristaltic pumps work by reducing the pressure in the sample tubing. Water must then rise up the tubing to equalize the pressure differential because the bottom end of the tube is open. The maximum theoretical vacuum that a peristaltic pump can create is 1 atmosphere, which at sea level is equal to 14.7 psi and equivalent to a 32 foot water column. In reality, the maximum lift the best peristaltic pumps generate in the field is about 27 feet, and this will decrease with increasing elevation.

Since peristaltic pumps apply a negative pressure to the water column, some people do not consider them suitable for collecting samples for VOC analysis.
