If a pump's lubricant is not compatible with a new installation, what should be changed?

When dealing with compatibility issues in a pump installation, especially concerning lubricants, it's crucial to recognize that seals and packing materials are designed to work with specific types of lubricants. If the lubricant is not compatible, it can lead to deterioration of these components, which may result in leaks or reduced performance.

Changing the seals or packing instead of the entire pump system or motor makes practical sense as it directly addresses the incompatibility issue without unnecessarily increasing costs or efforts associated with replacing other components that may still be functioning properly. This focused approach ensures that the pump can operate effectively with the new lubricant while maintaining its integrity and efficiency.

In contrast, changing the lubricant alone might not resolve the issue if the seals or packing are already compromised. Similarly, replacing the entire pump system or motor would be excessive since those components may not be impacted by the lubricant mismatch. Hence, opting for a change in seals or packing is the most targeted and effective solution.
