Laboport® PowerDry® Vacuum Pump for Saturated Vapors
Manufacturer: Knf Neuberger, Inc.
Family
Part #: KNF TSI-N8423FT40P
The chemically-resistant series N842.3FT.40P diaphragm pump is a two-stage unit with an integrated KNF self-drying system. There is a wide range of applications for this pump in laboratories, especially whenever clean vacuum is required and saturated gases must be pumped. Examples include vacuum-drying in 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, we were able to make the pumps smaller while increasing the service life of the diaphragm. The KNF PowerDry® system 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.
