All units are equipped with casing, impeller, and seal-chamber cover wear rings. When
clearances between the rings become excessive, hydraulic performance decreases substan-
tially.
Wear ring diameter check
Measure all wear ring diameters and then calculate the diametrical wear ring clearances. See
