The wear rings have three purposes to serve, 1. To decrease
the discharge fluid leak to the suction area and maintain
the pumps efficiency. 2. It acts as a bearing in a
multistage centrifugal pumping system. 3. It is economical
to replace the wear rings rather than replacing the
expensive impellers in case of any mechanical damage such
as, wear and tear due to abrassion or any other reasons.
