The chemically-resistant series N840.3FT.40P diaphragm pump is a twin-head 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 is a KNF structured diaphragm. This patented diaphragm was 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.
Technical Features:
- Pure transfer and evacuation
- Highly compatible with vapors and condensation
- Chemically-resistant
- Suitable for highly aggressive or corrosive gases and vapors
- Maintenance-free
- Environmentally friendly
- Gastight, leakage rate approx. 6 x 10-3 mbar x l/s
