Chemistry diaphragm pump MD 12C NT / Vacuubrand

Three-stage chemistry diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet the highest requirements. The three-stage design of the eight-cylinder MD 12C NT pump provides the advantageous combination of high pumping speed and very low ultimate vacuum. All internal parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life. With its gas ballast valve the MD 12C NT is optimally prepared for pumping easily condensable vapors, thanks to the very good ultimate vacuum even with open gas ballast valve also for high boiling solvents. Upgrade kits such as inlet separator (AK) and exhaust vapor condenser (EK) enable a later adaptation to changed process requirements. Eight-cylinder NT pumps features quiet operation with smooth, easy-to-clean surfaces. The high pumping speed of the MD 12C NT reduces the process time and meets the high vacuum requirements, e.g., of parallel processes in vacuum networks. Typical applications are large vacuum ovens and rotary evaporators, for example at pilot plants, mini-plants and kilo laboratories. The MD 12C NT is the particularly powerful base pump for vacuum systems and pumping units with vacuum control. Upgraded with a separator at the inlet the MD 12C NT is well prepared also for rough operating conditions. With a waste vapor emission condenser (available as accessory) at the outlet the pump offers excellent environmental friendliness due to efficient solvent recovery.
Chemistry diaphragm pumps from VACUUBRAND for aggressive gases and vapors are available in the basic version, with two-point or VARIO® control.
Chemistry diaphragm pumps from VACUUBRAND for aggressive gases and vapors are available in the basic version, with two-point or VARIO® control. Their construction with fluoropolymers makes them very resistant to chemical vapors from inlet to exhaust.
