Applications:

      
  • Mini pumps specially designed to pump small volumes.
  • Minimal size, low power consumption, high precision controllability.
  • Also deliverable with special long life ball bearings, as in the SP 250 EC-DB (“double ball”).
  • Made for portable machines, especially for gas analysis.
  • Gas-tight pump heads allow the unaltered delivery of the media.
  • Specific materials are also suitable for problematic gases.
  • Because of our modular construction system, we can customize the pumps to fit all requirements. Without increasing developing costs.
