Improved performance, increased pumping speed (up to 16 m³/h) and better ultimate vacuum (up to 0.3 mbar). Extend applications with non-aggressive gases whether used in the laboratory or for industrial processesVery low leak rate due to enhanced leak-tight tubing connections, resulting in consistent performance characteristics - even after many years of operation. Ideal for analytical applicationsLong diaphragm and valve lifetimes: made of highly flexible FPM, with fabric-reinforced double diaphragms for improved long term stabilityVery quiet and ultra low vibration due to compact drive with patented motor drive system. Ideal as a built-in component for sensitive analytical equipmentEasy to clean due to smooth surfaces. A robust solution for numerous applications in industrial environmentsThe VARIO® design provides vacuum control by precise and continuous adaption of the diaphragm pumps motor speed, and includes the vacuum pump, as well as the VACUU·SELECT controller.Country-specific power cord versions available on request.SpecificationsVacuum inletTubing nozzle DN 8-10 mm:ME 4 NT, ME 4R NT, ME 8 NT, MZ 2 NT, ME 2 NTKF DN 16:MZ 2D NT, MD 4 NT, MV 2 NT, MD 4 VARIO select, MD 2 VARIO selectPressure outletSilencer / G1/4":MZ 2 NT, MZ 2D NT, MD 4 NT, MV 2 NT, ME 2 NT, MD 4 VARIO select, MV 2 VARIO selectTwin silencers / G1/4":ME 8 NT, ME 4 NTTubing nozzle DN 8-10 mm:ME 4R NTKF DN 25:MD 12 NT, MV 10 NT, ME 16 NT, MD 12 NT VARIO select, MV 10 NT VARIO selectSilencer / G1/2":MD 12 NT, MV 10 NT, ME 16 NT, MD 12 NT VARIO select, MV 10 NT VARIO select

ATEX chemistry diaphragm pumps offer all advantages of oil-free chemistry diaphragm pumps. Typical applications are rotary evaporators and drying ovens with potentially explosive atmospheres. The ATEX approval includes the interior of the pump (in contact with pumped gases) as well as the surrounding area of the pump.Outstanding chemical resistance and superior vapor toleranceMainly made of antistatic materialsFlame proof motor with integrated, self-locking overload and excess temperature protection for direct 230V / 50Hz single phase power supplyOverpressure safety relief valves internally and at outletWith separate gas ballast connection part for use of inert gasSafety diaphragm technology with option for inert gas purge and detection of diaphragm breakageATEX compliance:Pump chamber (pumped gases): II 2G IIC T3 XExterior space (pump environment): II 2G IIB T4 X (with inert gas purging) / II 3G IIB T4 X (without inert gas purging)Speed-controlled ATEX VARIO vacuum pumps on request.SpecificationsMZ 2C EXVacuum inlet:Small flange KF DN 16Pressure outlet:Small flange KF DN 16MV 10C EX / MD 4C EXVacuum inlet:Small flange KF DN 25Pressure outlet:Kleinflansch KF DN 16MZ 2C EX+AK+EK / MD 4C EX+AK+EKVacuum inlet:Small flange KF DN 16Pressure outlet:Tubing nozzle DN 8-10 mmCooling water connection:2 x tubing nozzle DN 6-8 mm

The diaphragm pumps ME 1C offer a compact and high performance solution. With their easy-to-use functionality, they are the perfect partner for both single and multiple filtrations.One-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases and vapors for modest vacuum requirements. In contrast to water-jet pumps, they do not consume water and therefore do not produce any contaminated waste water in daily use.Vacuum filtration is frequently used for sample preparation in chemistry, microbiology, waste water control and analysis.In the chemistry diaphragm pumps ("C") all major parts in contact with pumped media are made of chemically resistant fluoroplastics. The ME 1C is also often used for solid phase extraction (SPE).An optional manual regulator valve with dial gauge enables variable fine adjustment of the pumping speed and the ultimate vacuum.Gas ballast for reliable pump performance.Two up to four stage chemistry diaphragm pumps (letters in the product name Z, D or V) are equipped with a manual gas ballast valve as standard. The supply of gas ballast minimizes the risk of condensation inside the pump.Diaphragm pumps ATEX-models available on request. Country-specific power cord versions available on request.
