Pump KNF N820.3 FTP
Pump KNF N820.3 FTP

The N series chemically resistant diaphragm pumps 820 and N 820.3 are single head and double devices head and dry running used in a wide variety of applications for laboratories. They transfer and empty without contamination. The heart of these pumps so Compact is a KNF structured diaphragm. This diaphragm patented was highly optimized using the Finite element method. As a result, we could get smaller bombs, but at the same time, with a Diaphragm with longer life.
