KNF N 920 G diaphragm vacuum pump, 21 L/min, 2 mbar, chemically resistant

The KNF N 920 G is a diaphragm vacuum pump with an ultimate vacuum of 2 mbar (abs.) and a flow rate of up to 21 L/min. It runs oil-free and does not contaminate the medium. It is used where the 6 mbar of the N 820 / N 840 series is no longer sufficient: drying, removal of low-volatility components, vacuum ovens.

Materials: PPS head, PTFE-coated diaphragm, FFPM valves. Chemical version G. Weight 9.5 kg.

Key features:

• Deep vacuum down to 2 mbar (abs.)
• Flow rate up to 21 L/min
• Chemical version G: PPS head, PTFE diaphragm, FFPM valves
• Oil-free, no contamination of the medium

Specifications:

• Max. flow rate: 21 L/min
• Ultimate vacuum: 2 mbar (abs.)
• Max. pressure: 0.5 bar (g)
• Weight: 9.5 kg
• Head: PPS
• Diaphragm: PTFE-coated
• Valves: FFPM

Application: Deep vacuum, drying, distillation of low-volatility media, vacuum ovens.

Before ordering: The achievable vacuum on site depends on the tightness of the line. Before ordering, check the operating pressure and connections in the documentation of the specific article.
