Rough Pump Rebuilds Q&A

What are the issues caused by poor vacuum?

Poor vacuum caused by an old or worn roughing pump can lead to potential trouble with high vacuum diffusion or turbomolecular pumps on a mass spectrometer. Rebuilt rough pumps can also be used to improve the vacuum for other lab equipment, including vacuum ovens and vacuum chambers.

How can I tell if my rough pump needs repair?

Certain signs of pending vacuum problems include oil leakage or an inlet pressure greater than 10 microns. If you have these issues or others, please contact us to discuss your options.
