12 Volt DC Purge Pumps

A purge pump is used to remove stagnant water from a monitoring well prior to sampling. The purged water is replaced by fresh groundwater from the aquifer. Purging may need to be repeated three or more times before the water in the well is representative of the surrounding aquifer.

Geotech's purge pumps use sealed electric centrifugal motors that get their power from a 12 Volt DC source, such as the Geotech 12 Volt DC Portable Rechargeable Battery. They are economical enough to be disposable, but can be easily cleaned and decontaminated for re-use. Unlike most submersible pumps they are not heavy and bulky and can easily fit into 5cm (2") wells.

Different configurations and options are available.
