Applications of membrane pumps
Pfeiffer Vacuum membrane pumps are suitable for a wide range of industrial applications. Some typical applications are analysis of organic or inorganic samples, coating of surfaces, vacuum filtration in chemistry and biotechnology, vacuum packaging of foodstuffs and vacuum distillation of liquids. Due to its high chemical and condensate compatibility, a diaphragm pump in the corrosive version can also be used when working with corrosive gases.
Areas of application
Suitable as backing pump for many turbopumps
Analytics
Chemistry
Laboratories
Leak detection
Research & Development
Systems and pumping stations
Practical in all areas where a dry, oil-free vacuum and particle-free pumping of gases are required
Using diaphragm pumps
to generate a backing vacuum for turbomolecular pumps
Since HiPace turbopumps have a 24 V DC power supply, Pfeiffer Vacuum diaphragm pumps are the ideal backing pumps. The electronic DC motor allows adjustments to the speed to be adapted to the specific requirements of the individual application. This results in high performance, long maintenance intervals and low noise and vibration levels. In addition, the diaphragm pump achieves particularly high energy efficiency thanks to its stand-by operation. The combination of Pfeiffer Vacuum membrane pumps and HiPace turbopumps represents a very efficient way of generating high vacuum.

Advantages of oil-free diaphragm pumps
Diaphragm pumps operate completely oil-free and do not generate any particles. This makes them suitable for all applications where a clean and dry vacuum is required. Another important advantage of diaphragm pumps is their long service life. In sensitive environments such as clean rooms, diaphragm pumps are not only reliable, but also have low vibration and noise levels. Noise levels are typically less than 50 dB(A).
The contamination-free pumping of gases in the laboratory, in the analysis and in the chemical industry is only one of the fields of application. This vacuum pump is also used in leak detection or research and development. In sensitive areas, the membrane pump is not only reliable, but also low in vibration and noise. This vacuum pump is also the ideal solution as a backing pump for turbopumps.
Reliable and usable worldwide
The long service life of the diaphragms makes this vacuum pump particularly interesting. Further advantages are the mature technology, the oil-free and absolutely dry vacuum generation as well as the high operational reliability of the pump. In addition, the diaphragm pump is easy to maintain. Both diaphragms and valves can be easily replaced. Time-consuming operations such as bearing replacement are usually not required. The pump can be used anywhere in the world thanks to its voltage-switchable motors or DC drives.
Maintenance and servicing of vacuum diaphragm pumps
Vacuum diaphragm pumps require little maintenance. The diaphragms should be cleaned and inspected regularly to ensure they are in good condition. The inlet and outlet valves should also be checked for damage or leaks. If necessary, parts can be replaced quickly and easily. Find information on our service and training portfolio.

Trends and developments in the application of diaphragm pumps
Trends and developments in the application of diaphragm pumps include the use of intelligent sensors that allow more precise control of pumping capacity or discharge pressure, as well as technologies that increase the energy efficiency and performance of the pumps. Our universal control unit OmniControl will help you manage a whole vacuum system with only one device. Other suitable intelligent accessories, such as automatic gas ballast valves, can be used to protect diaphragm pumps from condensable media in the process - significantly increasing process reliability.

Conveying light gases in leak detection technology
Diaphragm pumps are preferred in leak detection technology because they can combine their advantages with a very good pumping speed for light gases, especially helium. It is important here that the required backing vacuum pressure of the turbopumps used in the helium leak detectors is kept stable and that the regeneration capability of the leak detectors is maintained. The quiet and low-vibration operation ensures a comfortable working environment. Due to the very high efficiency, the power consumption is extremely low. Their light weight and compactness make diaphragm pumps ideally suited for integrating into ever-smaller analysis systems and turbo pumping stations, as well as for mobile applications.
Extensive range of accessories for vacuum diaphragm pumps
Pfeiffer Vacuum also offers a comprehensive range of accessories for its diaphragm pumps. This is because special tasks require the use of complementary parts or components. Special power cords are just as much a part of the range as the universal OmniControl operating unit, purge gas nozzles, hose connections or relay boxes.
