Laboratory vacuum pump ME 8C NT +2AK

diaphragmoil-free

Overview

• outstanding chemical resistance and superior vapor tolerance
• exceptionally high pumping speed even at low vacuum
• compact footprint for laboratory and benchtop use
• whisper-quiet operation with very low vibration (45 dBA at 50 Hz)
• long-life PTFE sandwich diaphragms and maintenance-free drive

Product description
The chemistry vacuum system ME 8C NT +2AK is an oil-free, single-stage diaphragm pump system designed for continuous pumping of corrosive gases and condensable vapors. The single-stage design combines a high pumping speed with a low ultimate vacuum down to 70 mbar. All wetted components are made of chemically resistant fluoroplastics (PTFE) to ensure compatibility with aggressive media. The integrated inlet separator protects the pump from particles and liquid droplets, while the outlet separator collects condensate. The NT series provides improved performance data and enhanced vapor tolerance. The unit is delivered completely mounted and ready for use with manual.
