Bladder Pumps

Bladders ensure no air/water contact during operation, providing representative groundwater samples and excellent VOC sample results. Bladder Pumps are also EPA approved for low flow groundwater sampling.

Double Valve Pumps

Double Valve Pumps are positive displacement gas drive pumps that provide high and low flow groundwater sampling, without the use of a bladder. Representative groundwater samples are produced, ideal when sampling for PFAS.
