Solinst Model 408 SS Double Valve Pump 1.66” x 2ft SS (3/8”D & 1/4”S)

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 and now features a simplified, lighter design for increased ease of use in the field. The NEW PVC Double Valve Pump option allows use in even more field conditions.

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. Stainless steel pumps can operate to depths of 150 m (500 ft) and the PVC Double Valve Pump can operate to depths of 30 m (100 ft).

Features

• 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: 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 flow-through cell are easily transported to each site with the DVP. Barbed fittings, quick-connect, and push-fit connections allow simple attachment to well caps or portable reels.
