Laboport<sup>&reg;</sup> Diaphragm Vacuum Pump 6KNN820-3FT / 6KNN820-3FT-40 (20 L/min)
 
The chemically-resistant series N820-3FT diaphragm pumps are Double-Head, oil-free devices used in a wide range of laboratory applications.  They transfer and pump down without contamination.

The core of these compact pumps is a KNF structured diaphragm.  This patented diaphragm was stress-optimized using the Finite Elements method resulting in smaller pump sizes while increasing the service life of the diaphragm.
