Laboratory vacuum pump ME 4R NT

diaphragmoil-free

Overview

• Contamination-free pumping, evacuation and compression
• High flow rate even near ultimate vacuum
• Adjustable inlet vacuum level and outlet pressure via regulator valves
• Very low vibration and oil-free operation
• Long diaphragm life and maintenance-free drive for low lifetime costs

Product description
This single-stage diaphragm pump operates as both a vacuum generator and a compressor. All parts in contact with the pumped media are aluminium and selected plastics; diaphragms and valves are PTFE. The materials make the ME 4R NT suitable for a wide range of applications with non-corrosive gases. Inlet and outlet are fitted with regulator valves allowing the user to limit or adjust vacuum and compression pressure. Inlet vacuum level and outlet pressure are shown on manometers.
