408 Double Valve Pumps (1.66" and 5/8")

Solinst Canada

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 up to 150m (500ft) for standing water level and the PVC Double Valve Pump can operate to depths of 30m (100ft).

Features & Applications

Easy Decontamination

Everything is easily accessible; replaceable and with inter-changeable 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.

Applications

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 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
