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.

• Application: Fluid aspiration, Degassing, Gel drying, Rotary evaporation, Centrifugal concentration, Distillation
• Flow rate up to 2.04 m³/h / Ultimate vacuum up to 8 mbar abs.
• High level of vapor and condensate compatibility
• PTFE pump head combined with PTFE-coated diaphragm are ideal for extremely aggressive/corrosive gases and vapors
• N 820.3 FT.18 and N 840.3 FT.18: ATEX-compliant in accordance with ATEX II 2/-G IIB+H2 T3 Gb internal atmosphere only

For Filtration, SPE, Degassing, Fluid aspiration.

• N 938.50 KT.18 ensures exceptionally fast evacuation by the parallel and in series connection of both pump heads
• PTFE-coated diaphragm is ideal for aggressive/corrosive gases and vapors
• Pump head made from PPS (Polyphenylsulfide), valves made from FFPM (Perfluoro rubber)

The diaphragm pumps ME 1 offer a compact and high performance solution. With their easy-to-use functionality, they are a 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.
Typical applications for the ME 1 are aqueous filtrations. The PTFE diaphragm and valves are rugged and provide high chemical resistance. If aluminium has the required specific resistance, solvent-containing samples can also be filtrated.

Heavy-walled and flexible.

Vacuum regulator valve for ME 1, ME 1C and MZ 1C with manual vacuum control using air bleed. The manometer can be mounted and pivoted in several orientations for optimal visibility. High chemical compatibility (especially with the vacuum regulator valve for ME 1C)

Premium module: The premium module comprises the inert gas inlet (only sizes 49/101), extra connectors for thermoshelves, one for VO29, two for VO49/VO101, an additional thermoshelf for model size 49/101.

Vacuum pump module: Without pump with antivibration metal plate at the bottom to accommodate the vacuum pump, including full-sight glass door, socket, signal cable and connecting hose to the vacuum oven.
