The Solinst Double Valve Pump (DVP) is a pneumatic drive pump that allows consistent, high quality samples. It has been field proven in thousands of applications. It offers excellent performance and reliability. No bladder replacement is required, and the Double Valve Pump provides higher pumping rates than with the Solinst Bladder Pump. There is a selection of sizes and materials, variable flow rates, and it is field serviceable.
Low Flow Sampling
Gives excellent VOC retention, comparable with bladder pump
results. When using the Solinst Model 464 Electronic Pump
Controller, the 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.
