Diaphragm pumps
for non-corrosive media
VACUUBRAND diaphragm pumps in aluminum design are powerful and are ideally suited for applications with non-corrosive media.
Thanks to the oil-free operation and the unsurpassed long-term performance, diaphragm pumps are frequently the first choice in the laboratory and in industry. As a backing pump for turbomolecular pumps, diaphragm pumps feature a particularly clean fore vacuum. Oil backflow and oil changes are avoided. In contrast to other dry-running vacuum technologies such as scroll pumps, diaphragm pumps additionally do not have any abrading seals which can generate wear.
The extremely long diaphragm service life is achieved through highly flexible double diaphragms made of the material FKM with fabric reinforcement. In addition, the pumps feature especially smooth operation. They are therefore also ideally suited for installation in equipment, such as in analytics.

Technical highlights
Dry operation, clean processes
Thanks to the dry and completely oil-free operation, diaphragm pumps are ideally suited for clean processes and the production of pure products. They do not generate either contaminated oil or wastewater. Diaphragm pumps are therefore also particularly low-maintenance and environmentally friendly. In addition, they do not have any sliding components in the gas path which can produce abrasion. There is thus no contamination from particles which frequently occurs in the case of scroll pumps.
Unsurpassed long-term performance
VACUUBRAND diaphragm pumps are known for their reliability and long maintenance intervals. The secret to success are the special diaphragm technology and selected materials which make the most heavily stressed components particularly resilient. An extremely long diaphragm service life is achieved through a highly flexible FKM double diaphragm with fabric reinforcement. As the result of multi-year performance tests, we have determined a typical diaphragm service life of 15,000 operating hours for our pumps. Thanks to the maintenance friendly design, diaphragms and valves can be easily changed. VACUUBRAND diaphragm pumps therefore run for many years with high reliability and require only minimal maintenance.
Tip: the efficient VARIO control increases maintenance intervals even further.
Smart vacuum control, efficient processes
Precise, efficient and quiet – VARIO diaphragm pumps control the vacuum according to need via the motor speed. In combination with the VACUU·SELECT controller, they achieve the optimal conditions for reproducible processes. Parameters and process steps can be easily adjusted and saved using the touch display. The corresponding interfaces enable integration in modern laboratory networks.
