VACUUBRAND Oil-free Chemistry Diaphragm Pumps

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.

• Three-stage design provides the advantageous combination of high pumping speed and very low ultimate vacuum
• All parts of the diaphragm vacuum pump in contact with pumped media are made of chemically resistant fluoroplastics
• Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life
• All multistage pumps are equipped with a gas ballast to provide consistent pump performance with condensed vapors
• Due to the gas ballast valve and its very good ultimate vacuum (even with gas ballast), the pump is also suitable for pumping condensable vapors of high-boiling solvents
• Further improved performance data, easy service, and superior vapor tolerance

Performance Features:

• Outstanding chemical resistance and superior vapor tolerance
• Exceptionally high performance even at low vacuum
• Excellent ultimate vacuum even with gas ballast
• Whisper quiet and very low vibration
• Long diaphragm life, maintenance-free drive system

NTRL approved.

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.
