Vacuubrand MZ 2C Diaphragm Vacuum Pump (Refurbished)

The Vacuubrand MZ 2C is a high-performance chemistry diaphragm pump designed for continuous, oil-free pumping of corrosive gases and vapors. With a chemically resistant flow path made entirely of fluoroplastics and PTFE sandwich diaphragms, it delivers excellent long-term durability and superior vapor tolerance.

The two-stage design provides an optimal combination of high pumping speed (2 m³/h) and low ultimate vacuum (7 mbar), making the MZ 2C ideal for rotary evaporation, vacuum drying, concentration, gel dryers, vacuum ovens, and a wide range of chemical and pharmaceutical processes.

The integrated gas ballast valve improves handling of condensable vapors, maintaining consistent vacuum even with high solvent loads. With quiet operation, low vibration, and a maintenance-free drive system, the MZ 2C is one of VACUUBRAND’s most widely used chemistry pumps.
