Solinst 408 Double Valve Pumps
Solinst 408 Double Valve Pumps
The Model 408 Double Valve Pumps are positive displacement, gas drive pumps providing high quality, consistent samples, and excellent VOC (Volatile Organic Compound) sample results. Pumps are available in stainless steel 5/8" diameter, and 1.66" diameter. Portable or dedicated versions are available. They can be fitted with packers to control groundwater flow and limit purge requirements. DVPs are easily disassembled for decontamination in minutes, without any tools.

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, 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.
Applications:
-
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. -
Non-Vertical Applications
Operates effectively at almost any angle and can be placed under landfills, tailings, storage tanks or plumes. -
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.
