Solinst’s Model 408M Micro Double Valve Pump (Micro DVP) is a pneumatic pump with a small and flexible design. Similar to a Bladder Pump, the 408M uses coaxial Teflon tubing instead of a Teflon bladder to obtain high quality samples and features stainless steel fittings and a 100 mesh stainless steel filter which is easily cleaned or replaced. The 408M Micro DVP is only 3/8″ in diameter, small enough to fit in 1/2″ (13 mm) tubing along with all channels of the Solinst 403 CMT System. Its pump body and filter measure 6″ x 3/8″ (150 x 10 mm). The 408M pneumatic pump, with its small size and flexible design, allows for easy transportation and installation in a wide range of applications.

Other pnuematic pumps manufactured by Solinst are the Integra bladder pump and the double valve pump.

The 408M Micro DVP is ideal for narrow down-hole applications and low flow sampling. From within narrow applications the Micro DVP obtains small associated purge volumes and flow rates of 20 to 150 mL/minute. It is built to last and easy to operate through the Solinst 466 ECU’s pre-sets and fine tubing capabilities. You can order the Micro DVP with tubing lengths of 90′, 140′, and 240 feet. Replacement filters are available.
