Abstract

A scroll pump or pumping system is configured to determine whether tip seals of the scroll pump require maintenance such as replacement. During operation of the scroll pump, pump inlet pressure is measured or calculated over a recent time period to acquire recent pump data. The recent pump data is compared to historical pump data, which is or includes pump inlet pressure measured over a historical time period preceding the recent time period. Based on the comparison, a determination is made as to whether tip seal maintenance for the scroll pump and/or further diagnosis of the scroll pump is required. If so, a user-interpretable output may be produced, indicating that tip seal maintenance and/or further diagnosis is required.
