How often should the temperature of centrifugal pump motor bearings be checked?

The correct practice is to check the temperature of centrifugal pump motor bearings on a monthly basis to ensure they are operating within acceptable limits. Regular monitoring of bearing temperatures is essential because overheating can indicate an issue such as inadequate lubrication, misalignment, or excessive load, which can lead to premature bearing failure and costly repairs. A monthly schedule strikes a balance between maintaining equipment reliability and not being overly burdensome in terms of labor and resources. This frequency allows operators to catch potential problems early while providing enough time between checks to identify trends or changes in temperature that might signal developing issues.
