• The effect of the inducer tip clearance on the pump suction performance is investigated with an inducer and two main impellers having different eye diameters. The experiment revealed the following : (1) When the eye diameter of the main impeller is nearly equal to the normal inducer tip diameter, the pump suction performance decreases with increasing tip clearance.(2) When the eye diameter is 90% of the normal inducer tip diameter, the pump suction performance scarcely changes with increasing tip clearance, provided that the inducer tip diameter is larger than the eye diameter.(3) When an inducer is followed by a different main impeller, the pump suction performance becomes different.Besides, the reason for the above relationship between the tip clearance and the pump suction performance is studied with the velocity and total head distributions measured at the inducer outlet.
