VACUUBRAND ME 2 NT Diaphragm Pump

Features
One-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases and vapors at low vacuum requirement. In contrast to waterjet pumps they do not consume water and therefore do not produce any contaminated waste water in daily use. Typical applications are vacuum ovens, filtrations and multi-port manifolds for medium throughput, as well as pumping of gases and oil-free evacuation in general. The one-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. Diaphragm vacuum pumps are an excellent choice for applications with non-corrosive gases and vapors. The materials used in these pumps like aluminum and special plastics are opening a wide range of applications. The highly flexible fabric-reinforced double diaphragm made of FKM is ideal for extended operating life.
