- Outstanding vapor tolerance
- Superior chemical resistance
The MD 1C diaphragm pump is a Three Stage chemistry design pump, which is an excellent solution for continuous dry oil free vacuum pumping of harsh and corrosive vapors and gases with high requirements regarding ultimate vacuum pressure.
The separator at the inlet (AK), made of glass with a protective coating, retains particles and liquid droplets. The waste vapor condenser at the outlet (EK) is highly efficient and compact. The condenser enables near-100-percent solvent recovery, efficient recycling and active protection of the environment.
The MD 1C has well-proven PTFE sandwich diaphragms increase reliability and extend operating life. The MD 1C with gas ballast valve is optimally prepared for pumping easily condensable vapors (high boiling solvents).
The MD 1C three-stage construction provides the advantageous combination of high pumping speed and deep ultimate vacuum in a pump with a very small footprint. All parts in contact with pumped media are made of chemically resistant fluoroplastics.
