Diaphragm Gas Pumps and Compressors

KNF Neuberger
Well-Balanced Solutions for Gas Processing

Industrial gas pumps from KNF are designed to minimize power requirements and reduce costs, perform an oil-free operation, run without wear-prone sliding seals, and incorporate precision ball bearings for optimized reliability.

There are 3 head configurations:

  • single-stage: for moderate performance
  • two-stage: for deeper vacuum
  • parallel-head: for higher flow

Various combinations of materials and coatings are also available, please contact us to learn more.
