How often should a centrifugal pump lubricant should be changed?

The frequency of replacement of lubricating oil in centrifugal pumps depends on the type of pump and operating conditions. For new pumps equipped with sliding bearings, it is recommended to change the lubricant 100 hours after the first operation and then every 300-500 hours. If you use less often, it can be replaced every six months. For rolling bearings, it is recommended to replenish lubricating oil after 1200-1500 hours of operation and completely replace it once a year. In addition, if the centrifugal pump works for less than 24 hours after the first use or replacement of the bearing, it is necessary to drain the lubricant and clean the rotor, and then replace it with new lubricant oil. The total replacement cycle is 6 months. These recommendations can help provide long -term efficient and safe operation of centrifugal pumps.
