Vacuubrand MD 4C 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.

-15,000 hours of continuous operation…if used 8 hours daily, then mean time between maintenance cycles will be about 5 years…Vacuubrand pumps will last about twice as long as our competitors…

-3-Year Warranty:  2 year standard plus additional year with registration…

-Chemical resistant flow path…The fluoropolymer is molded and reinforced…

-Scalability

-Oil free vacuum levels down to 2 mbar. Well below 50 mbar required for ethanol

-Vacuum control/modulation down to 1X10-3 mbar, good for Short-Path Applications
