These chemistry vacuum systems can be used in a wide range of applications for evacuating or moving gases and vapours between containers in chemistry and physics laboratories, e.g. as an alternative to water jet pumps and rotary vane pumps. Compact construction, very quiet running, long service life, diaphragm and valves are very easy to replace. Oil-free vacuum.

• Includes chemistry diaphragm pump with high chemical resistance (parts in contact with media are made from PTFE compounds and similar)
• High pump volume capacity even at low pressures
• Standard gas ballast valve for working with condensates
• Solvent recovery almost 100% with exhaust waste vapour condenser
• Simple manual control

Model ME 1C:
The ME 1C diaphragm pump offers a compact, high performance and easy to use solution which is perfect for single filtrations. This development, based on the highly successful technology of the oil-free diaphragm pump MD 1C, provides a well-proven and extraordinarily long diaphragm life time. The functional, space saving and innovative design with easily accessible, top mounted power switch ensures convenient and quick operation for day-to-day lab work. Robust PTFE diaphragms and valves provide optimal chemical resistance. A manual vacuum regulator valve with dial gauge for adjustment of pumping speed and ultimate vacuum is available as an accessory.

Model ME 2C NT:
This one-stage diaphragm pump is an excellent solution for continuous, oil-free pumping of gases and vapours at low vacuum requirement. In contrast to water jet pumps they do not consume water and, therefore, do not produce any contaminated wastewater in daily use. Typical applications are vacuum ovens, filtrations and multi-port manifolds for medium throughput, as well as pumping of gases and oil-free evacuation in general. The one-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar.

Model ME 4C NT:
This chemistry design diaphragm pump is an excellent solution for continuous, oil-free pumping of corrosive gases and vapours. The one-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. 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 NT series features further improved performance data, higher tolerance for condensates and simplified maintenance. The ME 4C NT is also available as chemistry vacuum system ME 4C NT +2AK with inlet separator to protect the pump against particles and liquid droplets, plus outlet separator to collect condensate.

Model ME 8C NT:
This chemistry design diaphragm pump is an excellent solution for continuous, oil-free pumping of corrosive gases and vapours. The one-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. All major parts in contact with pumped media are made of chemically resistant fluoroplastics. Well proven PTFE sandwich diaphragms for increased reliability and extended operating life. These large pumps have an exceptionally high pumping speed. The NT series features further improved performance data and superior vapour tolerance.

Model ME 4C NT +2AK:
The ME 4C NT is also available as a chemistry vacuum system ME 4C NT +2AK with inlet separator to protect the pump from particles and liquid droplets, plus outlet separator to collect condensate.

Model ME 8C NT +2AK:
The ME 8C NT is also available as a chemistry vacuum system ME 8C NT +2AK with inlet separator to protect the pump from particles and liquid droplets, plus outlet separator to collect condensate.
