Low Flow Sampling
Gives excellent VOC retention, comparable with bladder pump results. When using the Solinst Model 464 Electronic Pump Controller, the Double Valve Pump (DVP) can be adjusted to provide a continuous output of 100 ml/min or less.
Operates effectively at almost any angle and can be placed under landfills, tailings, storage tanks or plumes.
Pneumatic drive pumps may be used for pumping contaminant liquids. High solids content, solvents, hydrocarbons, and other chemicals are easily and economically pumped.
