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 to depths of 150 m (500 ft).

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.

High Quality Groundwater and Surface Water Monitoring Instrumentation

In 1975, Solinst began as a small reseller of geotechnical instruments. Through the early 1980’s, founder Doug Belshaw reshaped Solinst into a successful manufacturer of high quality groundwater and surface water monitoring equipment. Doug started by producing the Model 101 Water Level Meter, which provided the first, flexible polyethylene tape with an engineering scale (marked in tenths and feet).

Over the next 30 years, the Solinst product line developed into a full range of instruments, sold worldwide. Products include water level meters, interface meters, groundwater samplers, multilevel groundwater monitoring systems, remediation equipment, drive-point piezometers, and dataloggers and telemetry. In 1996, Solinst introduced the Levelogger® water level datalogger – the first combined absolute pressure sensor and datalogger in the industry.

As the Solinst brand grew, the company expanded to its current home in Georgetown, Ontario. With Jim Pianosi now as president, Solinst remains a successful and stable family-owned business in Canada.

HydroTerra has been working with Solinst as their exclusive representative in Australia for over a decade. Clients in Australia benefit greatly from the long-term collaboration between the two companies, and the superior technical and sales support they receive from such an experienced distributor.
