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. 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.
