Question

What is the purpose of the wear ring in a submersible pump?

• A. To support the impeller
• B. To prevent leakage
• C. To reduce wear between the impeller and casing
• D. To increase the pump's speed

Answer 1

Answer:

C. To reduce wear between the impeller and casing

The wear ring in a submersible pump primarily serves to reduce wear between the impeller and the casing. This component is crucial as it minimizes the friction and wear that occurs during the pump's operation, thereby enhancing the pump's longevity and maintaining its efficiency over time.
