Peristaltic Groundwater Sampling Pump

Peristaltic Groundwater Sampling Pump for Shallow Use

Waterra carries Peristaltic Groundwater Sampling Pumps because they are quite easy to use but peristaltic pump lift is more limited than other devices. They work by reducing the pressure in the sample tubing. Water rises 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 (8.2 m) at sea level and this will decrease with increasing elevation.

These pumps offer the advantage of simplicity in the field and the only component which is dedicated to the monitoring well is typically a piece of small diameter tubing which is very inexpensive. Additionally, flow with these pumps can be regulated easily making them quite suitable for low flow sampling.

Since peristaltic pumps apply a negative pressure to the water column, care must be used when collecting samples for VOC analysis since degassing is a possibility.

Let’s get started...

Make sure your water level is not below the lift capabilities of the pump you choose

You will need tubing for down the well AND peristaltic tubing for the pump head itself

Waterra Words of Wisdom

  • Peristaltic pumps use suction lift so are limited to about 27 feet (8.2 m)
  • Charge up your unit after field use so you are ready to go to the field
  • Waterra HDPE and LDPE Tubing can be dedicated to the well
  • Choose peristaltic tubing for your pump type and flow rate
