VACUUBRAND ME 4 NT Diaphragm Pump Ultimate Vacuum 70 mbar (52 Torr) Maximum Pumping Speed 2.6 CFM a (more)t 60Hz Number of Heads/Stages 2/1 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Whisper quiet - ME 4 NT with low vibration and higher pumping speed - Exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs Diaphragm pumps are an excellent solution for continuous, oil-free evacuation and pumping of gases. All parts in contact with pumped media are made of aluminum and selected plastics, allowing a wide range of applications for non-corrosive gases. The one-stage construction provides the advantageous combination of high pumping speed and an ultimate vacuum down to 70 mbar. The highly flexible fabric-reinforced double diaphragm made of FKM is ideal for extended operating life. The NT-series features further improved performance data. One-stage diaphragm pumps are an excellent choice for continuous, oil-free pumping at modest vacuum requirements. In contrast to water jet pumps, they do not consume water and therefore do not produce any contaminated waste water. Typical applications are vacuum ovens, aqueous filtrations and pumping and evacuation of non-aggressive gases in general. The ME 4 NT offers shorter evacuation times and higher gas throughput.INCLUDED: The VACUUBRAND ME 4 NT Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
