KNF N 86 diaphragm gas pump, up to 6.5 L/min, up to 2.5 bar, 100 mbar, for OEM

The KNF N 86 is a series of compact diaphragm gas pumps for integration into instruments (OEM). It transfers and compresses gases and vapours and generates vacuum without contaminating the medium. Series maximums: flow rate up to 6.5 L/min, pressure up to 2.5 bar (g), ultimate vacuum 100 mbar (abs.).

PPS head, EPDM or PTFE-coated diaphragm, FPM or FFPM valves. AC, DC and brushless DC motors, with digital adjustment in some versions. The pump is not lubricated and is maintenance-free in normal operation. Performance depends strongly on the motor and material configuration; high-temperature versions (.16) with different data are also available.

Key features:

• Oil-free gas pump for integration into instruments
• Gas transfer, compression and vacuum generation
• AC, DC or brushless DC motors
• Diaphragm and valve materials for the medium: EPDM/PTFE, FPM/FFPM
• Maintenance-free in normal operation

Specifications:

• Max. flow rate: up to 6.5 L/min (version dependent)
• Ultimate vacuum: 100 or 160 mbar (abs.), depending on materials
• Max. pressure: up to 2.5 bar (g), version dependent
• Head: PPS
• Diaphragm: EPDM or PTFE-coated
• Valves: FPM or FFPM
• Drive: AC, DC or brushless DC; digital adjustment in some versions

Application: Medical equipment, analytical instruments, gas analysis, emission monitoring, food industry.

Before ordering: Before ordering, specify the motor type and voltage, diaphragm and valve materials and the required duty point: flow, pressure and vacuum depend on the version.
