Laboratory vacuum pump ME 4C NT

diaphragmoil-free

Overview

• Outstanding chemical resistance
• High pumping performance near ultimate vacuum
• Whisper-quiet operation
• Low vibration (ME 4C NT)
• Long diaphragm life; maintenance-free drive

Product description
Chemistry-design diaphragm pumps provide continuous oil-free evacuation of corrosive gases and vapors. The single-stage construction combines a compact footprint with a high pumping speed and an ultimate vacuum down to 70 mbar. All wetted major parts are made from chemically resistant fluoroplastics; PTFE sandwich diaphragms improve reliability and service life. The NT series offers improved performance, higher condensate tolerance and simplified maintenance. The ME 4C NT can be supplied as a chemistry vacuum system ME 4C NT +2AK with an inlet separator to protect the pump from particles and liquid droplets and an outlet separator to collect condensate.
