Solinst Double Valve Pump

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 Integra® 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) and the PVC Double Valve Pump can operate to depths of 100 ft (30 m).

Applications:

  • Low Flow Sampling Gives excellent VOC retention, comparable with bladder pump results. When using the Solinst Model 466 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 plumes.
  • Leachate/Product Pumping Pneumatic drive pumps are well suited for pumping contaminant liquids. High solids content, solvents, hydrocarbons, and other chemicals are easily and economically pumped.

Features & Benefits:

  • Low Cost PVC This makes dedication more feasible for projects where budgets are tight. The lower capital cost allows several PVC pumps to be dedicated for the cost of one portable stainless steel pump. Dedicated pumps also save on field decontamination times and costs. A weight may be used to overcome buoyancy. PVC pumps are also useful for applications where stainless steel is unsuitable, such as: metals analysis and sampling highly corrosive liquids
  • Easy Decontamination Everything is easily accessible; replaceable and with interchangeable parts. 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.
