Description

The chemically-resistant series N 840 and N 840.3 diaphragm pumps are single- and double-head, dry-running 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.

Technical Features:

• 100% oil-free transfer
• Pure transferring and evacuation of gases
• Highly compatible with vapors and condensation
• Chemically-resistant
• Suitable for highly aggressive or
corrosive gases and vapors
• Maintenance-free
