Dual-pump Continuous Flow Systems

Teledyne Isco Series D continuous-flow systems couple two pump modules to a single controller, and use an active or passive valve manifold to provide non-stop, continuous feed of almost any fluid. The controller refills one pump while the other is delivering, using special algorithms to equalize pressure and flow of both pumps. This allows virtually pulseless transition at pump switchover while maintaining accurate flow rate.

Three different valve packages are available to accommodate all types of fluids and specific requirements of your experiment or process.

• Air valve continuous flow systems
  Pneumatic valves are constant-volume type for critical mass balance applications
  
• Electric valve continuous flow systems
  Reliable Hastelloy valves require no external compressed air or power supply
  
• Check valve continuous flow systems
  The economical choice for clean, low-viscosity fluids and stable downstream pressure
