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.

Features
- Environmentally friendly
- Maintenance free
- 100% Oil-free operation
- High level of gas tightness
- Pure transferring and evacuation of gases
- Version for slightly aggressive or corrosive gases and vapours
