Number of Heads/Stages

  • Outstanding chemical resistance and superior vapor tolerance
  • High performance even at low vacuum levels
  • Optimized vacuum even with gas ballast for condensate purge
  • Whisper quiet and low vibration
  • Long diaphragm life, maintenance-free drive system

Chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors. The two-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum. All parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms increase reliability and extend operating life. The pump MZ 2C NT is equipped with a gas ballast valve for continuous condensate purge increasing the pumping capability of condensable vapors. This pump is our most popular chemistry diaphragm pump, and is the heart of a family of VACUUBRAND pumping systems. The NT-series features further improved performance data and superior vapor tolerance. Two-stage chemistry-design diaphragm pumps are an excellent choice for applications with corrosive gases and vapors with medium vacuum requirements. They do not consume water and therefore do not produce any contaminated waste water. The media contacted materials made of chemically resistant fluoroplastics open a wide range of applications in chemistry and pharmaceutics. The robust design provides very good durability and long service intervals even in demanding chemistry applications. Typical usages are vacuum generation for rotary evaporators, vacuum concentrators, gel dryers, vacuum ovens and many other laboratory applications. The MZ 2C NT is the powerful basic pump for a complete family of well established and reliable chemistry vacuum systems and pumping units.

The VACUUBRAND MZ 2C NT Chemistry Diaphragm Pump includes:
  • Power Cord
  • Operator's Manual
  • Manufacturer's Documentation
  • 2 Year Manufacturer's Warranty
