Avoid this unique and specific type of cavitation caused by the impeller passing too close to the cutwater(s) on a volute-style pump.
Jim Elsey
The placement of the cutwater, its length, thickness, leading edge profile and flow angle all have roles in the casing efficiency.
The impeller and casing must be matched to each other or the results will be a disaster.
