LABOPORT® Diaphragm Pumps for Air, Gases and Vapors

KNF N 816.1.2 laboratory pumps are double-headed, dry-running devices used in a wide range of applications. They transfer and pump down without contamination.

The pump diaphragm is stress-optimized by using the finite element method (FEM). This results in a much smaller physical size and a noticeably increase in the service life of the diaphragm.

These pumps are available in various versions differing in the materials which contact the media. Please contact us for more details.
