Solinst Model 408M Micro Double Valve Pump 5/8" x 1' Geophysical & Survey The Magnehelic ® gage isThe 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
