PowerDry® Vacuum Pumps for Saturated Vapors LABOPORT® PowerDry® Vacuum Pump for Saturated Vapors LABOPORT® Series N840.3FT.40P Vacuum Pump The chemically-resistant series N840.3FT.40.18 diaphragm pump is a twin-head 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 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. Technical features: ˾ Pure transfer and evacuation ˾ Highly compatible with vapors and condensation ˾ Chemically-resistant ˾ Therefore 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, not tested in serial production. Material in contact with the pumped media Type/Order No. Pump head Technical data: N840.3FT.40P 34 Delivery (l/min)1) The heart of these very compact pumps are KNF structured Ultimate vacuum (Torr) 8 diaphragms (PTFE-coated). These patented diaphragms Operating pressure (psi) 15 were stress-optimized using the Finite Elements method. Connectors for tube (in.)
