Diaphragm pump in action

Diaphragm pumps are an excellent solution for continuous, oil-free evacuation and pumping of gases. All parts in these MZ 2 series pumps that are in contact with pumped media are made of aluminum, stainless steel and selected plastics, allowing a wide range of applications for non-corrosive gases. The two-stage construction provides the advantageous combination of high pumping speed and an ultimate vacuum down to 4 mbar. The highly flexible fabric-reinforced double diaphragms made of FKM provide high reliability and extended operating life. The NT-series features further improved performance data and compact design. Two-stage diaphragm pumps are an excellent choice for continuous, oil-free pumping at medium vacuum requirements. In contrast to water jet pumps, they do not consume water and therefore do not produce any contaminated waste water. Typical applications are vacuum ovens and aqueous filtrations. The MZ 2D NT is ideal as backing pump for turbomolecular drag pumps and for pumping down in helium cryostats due to its better ultimate vacuum.
