Diaphragm Vacuum Pumps for Backing Turbo Pumps: Up to 40,000 hours maintenance-free operation of diaphragm pumps
State-of-the-art turbo pumps with integrated molecular drag stage can be operated with fore-vacuum levels in the single-digit mbar range, permitting oil-free diaphragm vacuum pumps to be used for backing. Because of advances in diaphragm technology and electronic drives for variable speed operation, diaphragm pumps are now even more compact, powerful and reliable. Long term tests indicate diaphragm lifetimes in excess of 40,000 hours and ultimate vacuum within specifications over the entire test period. Variable speed drive systems also extend maintenance intervals for backing pumps to the point at which they are comparable to those of turbo molecular pumps.
