I'm very interested in the advances in high purity, oil-less systems for use in areas demanding high cleanliness.
~Matt B., Design Engineer, Albuquerque, NM
magnetic bearing system for turbo-molecular pumps
hydro-kinetic fluid drive for mechanical booster pumps
~Engineering, Other, Bucharest, Romania
Controls, variable speed drives and such. The nuts and bolts of the pumps haven't changed significantly.
~Tom S., Engineer, Rockland, MA
Improved reliability
Improved cost of ownership
Improved performance
Predictive maintenance
~Terry R, Marketing/Sales, Rochester, NY
The development of dry pumping systems, especially for the semiconductor processes.

From your perspective, which companies are creating the most innovative mechanical vacuum pumps and systems?
18 answers
Edwards
Oerlikon Leybold Vacuum
Busch Vacuum
~Robert C, Sr. Manager - Marketing and Services, Export, PA
Probably Busch with the dry screw performance, although I believe with a better effort a centrifugal compressor could out perform all in the end using the inlet as the flows are usually better per hp used.
~Rich F, Technical Support, Hammonton, NJ
Edwards, Aeybold and Alcatel Smaller companies such as Won Chang, Korea, offer good quality vacuum pumps at affordable prices.
