QED Sample Pro 3/4" Portable Micropurge Groundwater Sampling Pump

The QED Sample Pro portable micropurge pump is designed for collecting groundwater samples from small diameter wells and direct-push boreholes. At just 0.75" O.D. by 10.5" long, the 3/4" pump fits in wells as small as 3/4" schedule 40. Plus, the pump is rugged and reliable for easy use in the field, easy to assemble and no tools are needed for assembly or cleaning.

Direct push technology and low flow sampling reduce the costs of well installation, sampling and purge water handling. The 3/4" pump minimizes turbidity and silting caused by well surging for more consistent samples and fewer false positives and resamplings.

The pump is also available with a 1.75" diameter to fit in 2" monitoring wells or larger. Both models can pump from depths as deep as 200 ft.
