LABOPORT® Diaphragm Vacuum Pumps and Compressors

KNF N 86 series pumps are single-headed, dry-running devices used in a wide range of laboratory applications. They transfer, compress and pump down without contamination.

By using the finite element method (FEM) during the design process, the structured, stress-optimized diaphragm makes it possible to reduce the physical pump size while increasing the service life. These pumps are compact, durable and portable.
