Using an intelligent test algorithm, Leybold draws upon its extensive vacuum expertise. "Through our many years of experience, we now know exactly to what extent a pump's operating noise indicates its condition," explained Dr. Sina Forster, the Project Manager heading up the project for Leybold.

While the human ear can't perceive various pump noises above a certain frequency, the app can quickly and objectively detect the condition of the gears and/or bearings. If deviations occur, they're detected immediately by the test algorithm, and the probability of an error is then displayed. "From an acoustic analysis of the vacuum pump, we can come up with specific recommendations and schedules for service and maintenance work, such as belt changes," explained Dr. Forster.

The sound analysis represents a major economic advantage and encourages compliance with suggested service intervals. Based on the test results, customers can contact Leybold Service directly and transmit the sound data for a more detailed analysis. Depending on the condition of the vacuum pump, it can be determined if service is due without the need for a service call. As such, repair and maintenance work, in addition to downtimes for the entire system, can be anticipated and planned.
