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 FEP ® tubing, rather than an FEP bladder to give high-quality samples. It is small enough to fit in 3/4'' (19.05 mm) tubing and all channels of the Solinst Model 403 CMT Systems, as its diameter is only 5/8'' (14.875 mm). The unique combination of flexibility and size makes 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. Applications Groundwater sampling in: CMT and Waterloo Multilevel Systems Direct-Push/Drive-Points Low flow monitoring in narrow diameters Advantages Only 5/8'' (15.875 mm) in diameter Flexible FEP goes almost anywhere Inexpensive and readily dedicated Narrow applications
