Wearing rings are installed in a pump to?

Explanation:
Wear rings are sacrificial surfaces placed between the impeller and the pump casing. They take the wear from abrasive fluid, protecting the impeller and the casing from damage. By wearing instead of the impeller, they help preserve the pump’s efficiency and enable easy, inexpensive replacement when worn. They also help maintain the proper clearance to limit leakage. They aren’t used to hold the shaft or keep the impeller seated—those duties come from bearings, keys, and retaining devices.
