VACUUBRAND MZ 2 NT Diaphragm Pump Ultimate Vacuum 7 mbar / 5.2 torr Maximum Pumping Speed 1.4 cfm at (more) 60Hz Number of Heads/Stages 2/2 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Whisper quiet - Very low vibration - Xxceptionally 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 and allow a wide range of applications for non corrosive gases. The two-stage construction provides the advantageous combination of high pumping speed and an ultimate vacuum down to 7 mbar. The highly flexible fabric-reinforced double diaphragm made of FKM is ideal for extended operating life. The new NT-series features further improved performance data. Two-stage diaphragm pumps are an excellent choice for continuous, oil-free pumping at medium 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 and aqueous filtrations. INCLUDED: The VACUUBRAND MV 2 VARIO Select Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
