Laboport^® Diaphragm Vacuum Pump for Air, Gases and Vapors 6KNN860-3FT / 6KNN860-3FT-40 (60 L/min) / 6KNN860-1-2FT (110 L/min)

The chemically-resistant series N860-3FT and N860-1-2FT diaphragm pumps are our largest laboratory Twin-Head unit. There is a wide range of applications for this pump in laboratories, especially when clean vacuum is required.

Examples include vacuum-drying of vacuum oven chambers (for drying or heat-treating substances and components) or steam sterilizers for sterilizing instruments, vessels, filters and textiles. Due to its high resistance to aggressive media, this pump can be used universally.

The heart of these very compact pumps are KNF structured diaphragms (PTFE-Coated). These patented diaphragms were stress optimized using the Finite Elements method. As a result, the pumps are more compact while increasing the service life of the diaphragm.

Optional KNF PowerDry^® system (Model no. 6KNN860-3FT-40) allows condensed liquid to be blown out of the pump heads at high speed during evacuation. The vacuum in the vessel is not disturbed. The drying cycle can be adjusted to the requirements of the individual process using three variables. After drying, the pump reaches a better vacuum and is able to evacuate significantly faster compared with pumps without a drying system.
