Chemistry diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapours at medium vacuum requirements. The two-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum.

• All major parts in contact with pumped media are made of chemically resistant fluoroplastics.
• Well-proven PTFE-sandwich diaphragms increase reliability and extend operating life.
• The MZ 1C pump is equipped with a gas ballast valve for continuous condensate purge increasing the pumping capability of condensable vapours.
• Slim design for space-saving installation.
• Good vacuum performance.
• A manual vacuum regulator valve with dial gauge for adjustment of pumping speed and ultimate vacuum is available as accessory.
• No water consumption and therefore no production of any contaminated waste water.
• Powerful pump for smaller vacuum apparatus enabling continuous pumping of solvent vapours.
• Compact, stand alone pump with low ultimate vacuum.
• Outstanding chemical resistance and superior vapour tolerance.
• Convenient, quick and simple to use due to the top mounted power switch.
• Optimised vacuum even with gas ballast for continuous purge.
• Whisper quiet and very low vibration.
• Maintenance-free drive system and proven long diaphragm life.
• Items supplied: pump completely mounted, ready for use, with manual.
