The Solinst 408 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, and it is field serviceable.

No bladder replacement is required, and the Double Valve Pump provides higher pumping rates than with the Solinst Bladder Pump.

The Double Valve Pump is suitable for low flow or regular flow sampling. The stainless-steel pumps can operate to depths of 150m.


• Easy Decontamination Everything is easily accessible or replaceable without the need for tools. All components can be cleaned
with mild detergent or non-phosphate soap.
• Survives Dry Pumping, Dirty Air and Sand Pumps are not damaged by operation in sediment laden water, or in dry pumping
• Saves Time and Costs Low flow sampling reduces purge volumes and the time it takes to obtain a sample. There is less need for
repeat sampling, which reduces the time needed for each sampling round.
• Part of Simple System The air compressor or tank, pump controller, and flowthrough cell are easily transported to each site with
the DVP. Compression fittings, quick-connect, and push-fit connections allow simple attachment to well caps or portable reels.


• 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.
• Non-Vertical Applications Operates effectively at almost any angle and can be placed under landfills, tailings, storage tanks or
• Leachate/Product Pumping Pneumatic drive pumps may be used for pumping contaminant liquids. High solids content, solvents,
hydrocarbons, and other chemicals are easily and economically pumped.
