Diaphragm pumps

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.

• Application: Degassing, Gel drying, Rotary evaporation, Distillation
• Flow rate 1.26 m³/h / Ultimate vacuum 2 mbar abs.
• High suction speed, particularly in the low vacuum range
• Integrated rotational speed control enables pumping capacity to be easily adapted manually to process requirements
• PPS pump head combined with PTFE-coated diaphragm are ideal for aggressive/corrosive gases and vapors
• Integrated gas ballast valve

Tip: When combined with the VC 900 vacuum control unit and the connection cable, the rotational speed is controlled in accordance with the requirements of the process.

The two-stage pump is designed for pumping and compressing gases and vapours and generate vacuum e.g. for rotary evaporators, vacuum ovens and gel dryers. Their electrical conductivity prevents electrostatic charging and minimizes the risk of the gas mixture igniting inside the pump.

• For tubes with ID = 8 mm
• Chemically resistant
• Resistant to aggressive solvents and acid vapours
• Elastomer diaphragms with PTFE layer
• Pump and connection heads are carbon fibre reinforced
• Integrated motor protection switch
• Vibration isolating feet

Scope of delivery: 2-head chemical diaphragm pump, external power supply and device connection cable with plug (EU, UK).
