Laboratory vacuum pump N842.3FT.40P

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 vac- uum 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.
