KNF LABOPORT N 840 G chemical vacuum pump, 34 L/min, 6 mbar, PTFE, for evaporation

The KNF LABOPORT N 840 G is the largest pump of the LABOPORT chemical series: flow rate up to 34 L/min at an ultimate vacuum of 6 mbar (abs.). It is a chemically resistant oil-free diaphragm pump with a PTFE/TFM head, PTFE-coated diaphragm and FFPM valves.

Speed control and a gas ballast valve are part of the design. The pump is used on rotary evaporators with larger flasks, for distillation, gel drying, degassing and as the base unit of a vacuum system with separator and condenser. Weight 11.3 kg. ATEX applies to the internal atmosphere.
