Wearing rings are installed in a pump to achieve what?

Explanation:
Wear rings act as sacrificial, replaceable surfaces between the impeller and the pump casing. Their job is to take the wear that occurs during operation, protecting the more expensive components like the impeller and casing. By concentrating wear on these inexpensive rings, you can replace just the rings when wear or leakage becomes a problem, keeping overall pump costs down and making maintenance easier. Other effects like leakage control or efficiency are related, but they’re secondary to the main idea: wear is localized to an economical part that’s easy to replace.
