VacuuBrand's ME series Single Stage Diaphragm Vacuum Pumps operate oil-free, whisper quiet, reliably, and require very little service, making them ideal for laboratory and industrial applications.  Made with long life diaphragms and a drive space which is hermetically sealed from the pumping chamber to protect mechanical parts from corrosion.  These compact vacuum pumps provide very high performance from a high pumping chamber volume relative to the minimal dead space.  These single-stage diaphragm pumps will achieve as much as 70 mbar (absolute) vacuum. 

Applications

• Rotary evaporators :

• Universal chemical resistance for any solvent combination,

• Vacuum filtration 

• Solid phase extraction

Features

• Highly flexible FKM double diaphragms with fabric reinforcement improves long term stability and ensures an extremely long diaphragm lifetime,

• Operate absolutely oil free to eliminate this source of contamination,

• No sliding components in the gas path to operate completely free of abrasion for a long service intervals and elimination of most of the particulate impurities and contamination frequently generated inside of scroll or piston pump, making them ideal for clean applications.

• Most pumps approved for ATEX equipment category 3 in the vapor path, with "EX" versions available for category 2 applications, (Call us for additional information.)

• Sensors ensure a trouble free evaporation without superheating solvents, even low or high boiling ones,

• Top mounted power switch is convenient, quick, and simple to use,

• VARIO® option provides precise and automatic vacuum control to save time and avoid sample loss,

• Whisper quiet and very low vibration for improved working environment and low disturbance of benchtop applications, 

• Compact design requires minimal benchtop space, 

• High reliability from maintenance-free drive system and proven long life diaphragm,

• Innovative connections in the patented NT models ensure very low leak rates for excellent flow rates under vacuum and long-term performance stability, even after thousands of hours of service,

• Chemical "C" type ideal for pumping of aggressive gases and vapors using PTFE and aluminum for all wetted materials:

• PTFE sandwich diaphragms and valves made of perfluoro elastomer or PTFE

• Internal tubing and fittings made of PTFE/ETFE/ECTFE compounds

• Exceptional diaphragm lifetimes with ultra-durable PTFE sandwich design

• Head cover and clamping disc made of fluoro compounds with stability core for unsurpassed long-term performance

• Very long service intervals for low lifetime cost-of-ownership

• New features of "NT" designated models: 

• Patented drive system for extra quiet, ultra-low-vibration operation,

• Patented valve mounting system to simplify service access,

• Smooth surfaces for easy cleaning,

• Sealing system provides reduced leakage rates for improved ultimate vacuum.
