Wear rings can be defined as a device used to seal the
pressure leakage of the liquid between the inlet of the
impeller and the pump casing. Wear rings are typically
found on pumps with closed impellers. A similar device that
serves the same function called a wear plate can be found
on some pumps with a semi-open impeller.
The typical reason for using a wear ring is to decrease the
amount of leakage loss around the impeller. Due to more
work available to push the pumped liquid out the discharge
there is a slight improvement in pump efficiency.
