• High flow rate even near ultimate vacuum
• Low noise and very low vibration
• Fabric-reinforced FKM double diaphragm with extended service life
• Included VACUU·SELECT vacuum controller with external gauge head

Key product data

• Ultimate vacuum: 70 mbar
• Max. pumping speed (50 Hz): 19 m³/h

Description
Oil-free, one-stage eight-cylinder diaphragm pump designed for evacuation and pumping of non-aggressive gases. Components in contact with the pumped medium are aluminium and selected plastics suitable for a wide range of industrial applications. The fabric-reinforced double diaphragm made of FKM provides extended operating life, which increases further when the motor is speed-controlled. The ME 16 NT VARIO select combines high pumping speed, compact footprint and smooth, easy-to-clean surfaces. The unit is supplied mounted and ready for use, including silencer and manual, and is controlled via the VACUU·SELECT external gauge head.
