Vacuubrand MD 4C Diaphragm Vacuum Pump
Up for sale is a MD 4C Diaphragm Vacuum Pump. It's in great used condition, as shown in the pics. It was acquired as surplus from a working lab. It has been tested and holds a strong vacuum.
Outstanding chemical resistance and superior vapor tolerance. Exceptionally high performance even at low vacuum. Excellent ultimate vacuum even with gas ballast. Whisper quiet and very low vibration.
Long diaphragm life, maintenance-free drive system. Three-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet even challenging requirements. The three-stage design provides the advantageous combination of high pumping speed and very low ultimate vacuum. All parts of the MD 4C NT in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life. Due to the gas ballast valve and its very good ultimate vacuum (even with gas ballast) the MD 4C NT is also suitable for pumping condensable vapors of high-boiling solvents. The NT-series features further improved performance data, easy service and superior vapor tolerance. Three-stage chemistry-design diaphragm pumps are an excellent choice for applications with corrosive gases and vapors with high vacuum requirements. Typical applications are parallel and rotary evaporators, concentrators, drying ovens and many other laboratory applications. The MD 4C NT has an outstanding performance for pumping large amounts of vapor, e. Out of drying ovens and gel dryers. This powerful pump is at the heart of a complete family of well-proven and reliable vacuum systems and pumping units for larger lab applications. 1.5 mbar / 1.1 torr.
