KNF LABOPORT N 820 G chemical vacuum pump, 20 L/min, 6 mbar, PTFE, for rotary evaporators

The KNF LABOPORT N 820 G is a laboratory diaphragm vacuum pump from the chemical series for aggressive gases and solvent vapours. Flow rate up to 20 L/min, ultimate vacuum 6 mbar (abs.). The PTFE/TFM head, PTFE-coated diaphragm and FFPM valves withstand corrosive media.

Speed control and a gas ballast valve are provided. The pump is compatible with vapours and condensate and can be extended with a separator and a condenser. Typical tasks: rotary evaporator, distillation, degassing, drying, gel drying, SPE, vacuum oven. Weight 8.8 kg. ATEX applies to the internal atmosphere of the pump only.

Key features:

• Chemically resistant wetted parts: PTFE/TFM, PTFE, FFPM
• Speed control and gas ballast valve
• Handles vapours and condensate, can be extended with separator and condenser
• ATEX for internal atmosphere: II 2/-G IIB+H2 T3

Specifications:

• Max. flow rate: 20 L/min (1.2 m³/h)
• Ultimate vacuum: 6 mbar (abs.)
• Max. pressure: 0.1 bar (g)
• Weight: 8.8 kg
