Solinst Model 408M | Bladder Pump System | Water level meters | Water sampling equipment | Water quality testing

The Micro Double Valve Pump (Micro DVP) has a remarkably small and flexible design. It is a pneumatic pump similar to a Bladder Pump, but using coaxial Teflon® tubing, rather than a Teflon bladder to give high quality samples. It is small enough to fit in 1/2" (13 mm) tubing and all channels of the Solinst Model 403 CMT Systems, as its diameter is only 3/8" (10 mm). The unique combination of flexibility and size make the pump easy to transport and install in a variety of applications.

The Micro DVP is ideal for low flow sampling and narrow down-hole applications. Flow rates of 20 to 150 ml/min, are obtained, with very small associated purge volumes from within the narrow applications. The Micro DVP is durable and easy to operate using the pre-sets and fine tubing capabilities built into the Solinst Model 466 Electronic Control Unit.
