The Solinst 408 Double Valve Pump (DVP) is a pneumatic-drive pump which consistently delivers high quality samples. It is extremely popular in the field, having proven itself in countless applications, without ever requiring a bladder replacement.
Solinst 408M Micro Double Valve Pumps
The Micro Double Valve Pump (Micro DVP) is designed to be small and flexible making it ideal for use in narrow boreholes when doing low flow sampling. Instead of using a bladder, the Micro DVP uses coaxial PTFE/FEP tubing making it suitable for CMT or wells with diameters less than 10mm.
