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.
