KNF LABOPORT N840FTP Chemically Resistant Diaphragm Vacuum Pump, Single-Stage, 34 L/min Flow Rate

The chemically-resistant series N840 and N840.3 diaphragm pumps are single and double-head, oil-free devices used in a wide range of laboratory applications. They transfer and pump down without contamination. The heart of these very compact pumps is a KNF structured diaphragm. This patented diaphragm was stress-optimized using the Finite Elements method. As a result, we were able to make the pumps smaller while increasing the service life of the diaphragm.
