Model 408 Double Valve Pumps
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.
The DVP is suitable for low flow or regular flow sampling. The stainless steel pumps can operate to depths of 500 ft (150 m).
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 conditions.
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.
