Brandtech* MD4C Vacuum Pump

MD4C diaphragm pumps are totally oil-free, mechanical 3-stage vacuum pumps. A special geometry of displacement and head space provides a low ultimate vacuum of approx. 2 mbar and a high volume flow rate. Optimized kinetics for minimum work and wear of the diaphragm result in high reliability, long life and low noise level. All parts coming into contact with gases and vapors are made of chemical-resistant fluorinated plastic materials. Typical applications are rotary evaporators, vacuum drying chambers, vacuum concentrators, distillation, gel dryers and transfer of aggressive gases and vapors.
