Electrical Submersible Sampling Pumps

Electrical submersible pumps are the logical choice for monitoring wells when high flow rate purging and low flow sampling is required. They are very reliable and provide continuous sampling rates over extended periods of time, desirable qualities for dedicated monitoring wells.

Geotech offers many submersible pumps made for groundwater sampling. They are constructed from stainless steel and PTFE polymers for easy sample integrity and decontamination.
