New Neuberger KNF N820.3FT.40P LABOPORT, Self Drying, PowerDry® Vacuum Pump for Saturated Vapors, 20 l/min (0.70 CFM), 29.7 inHg (8 Torr) Two Stage Diaphragm Vacuum Pump 115 VAC. (KNF Part No. 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.
