NEW Neuberger KNF Laboport N820.3FT.40P (8 Torr) 2 Stage Diaphragm Pump 115VAC, PN N820.3FT.40P

The chemically-resistant series N820.3FT.40P diaphragm pump is a two-stage unit with an integrated PowerDry® self-drying system. There is a wide range of applications for this pump in laboratories, especially whenever clean vacuum is required and moist gases must be pumped down. 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, 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. This is a new pump and set up for 115 Vac 60 Hz. Hose connections are 3/8 inch ID barb style connectors. 3/8 inch ID vacuum grade vinyl hose tubing is available on this website, Part No. P103304.
