MD 4C NT / 20736403 Overview:
The Vacuubrand MD 4C NT is a three stage new technology chemistry resistant diaphragm pump. MD 4C offers superior solution for continious dry oil free vacuum pumping of corrosive gases and vapors.
The three stage design of MD 4C NT provides the advantageous combination of high pumping speed and very low ultimate vacuum. All parts of the Vacuubrand MD 4C NT in contact with pumped media are made of chemically resistant fluoroplastics.
Superior design of 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 Vacuubrand MD4C NT is also suitable for pumping condensable vapors of high-boiling solvents.
The new MD 4NT diaphragm pump series features improved performance data, user friendly service and excellent vapor tolerance.
MD4CNT Scope of Delivery:
- Pump completely mounted
- Manual
MD4CNT Applications:
- Drying
- Rotary evaporation
- Vacuum concentration
- Filtration
- Local area vacuum networks
- Reactors & synthesis applications
- Fore vacuum generation for turbomolecular pumps
