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. One-stage chemistry diaphragm vacuum pumps are an excellent choice for applications with corrosive gases and vapors which do not require very deep vacuum levels. Typical applications are vacuum ovens, filtrations as well as concentration of solvents with low boiling points. All major parts in contact with pumped media are made of chemically resistant fluoroplastics. The well proven robust PTFE sandwich diaphragm provides outstanding reliability and operating life.
