QED Sample Pro
Bladder Pump - 1.5" or 0.75"
Featured Rental
The QED Sample Pro features disposable bladders and can be quickly dissassembled in the field for decontamination allowing a single pump to be used for sampling multiple wells. Bladder pumps provide high quality representative samples since the compressed air that powers the pump never contacts the sample and the pumping action causes minimal disturbance. Our bladder pump rentals come in multiple configurations for various situations and can fit in even the smallest wells. The pumps can be operated using a backpack controller powered from a CO2 tank, a gas powered compressor, or a 12 VDC compressor. When ordered with grab plates, the tubing is simple pushed into the pump creating a tight seal and saving time between wells. Although any flow cell meter can be used with these pumps, we also offer flow cells and water level meters specifically designed for use with this system.
