  Double Valve Pump Range

The Solinst Double Valve Pump (DVP) is a pneumatic drive pump that delivers consistent, high quality samples at low flow rates up to a depth of 150m

Low-flow sampling offers excellent quality samples by reducing turbulence. It also reduces purge volumes, which reduces sampling time and the cost of disposing of contaminated groundwater.

Flow rates are adjusted using an Electronic Pump Control Unit from up to 1.6 l/min to below 0.1 l/min. Use of an in-line flow-through cell (see our WQMP Multiparameter Meter) allows continuous analysis of purge water so that sampling can begin as soon as readings stabilise.

Some key features:
• Higher pumping rates than the Bladder Pump.
• Deep applications: - maximum operational depth of 150m.
• The system is suitable for pumping most types of product and contaminated liquids.
• Easy decontamination and low maintenance.
• Copes well with sediment.
• Excellent performance and reliability - no bladder replacement.
• Can be converted to a bladder pump (standard system only).
