The outlet shape and conditions affect widely the axial pump performance. The space axial distance between the pump impeller and stator plays an important roll in determin-ing the outlet conditions. An experimental investigation has been carried to study the pump performance without stator, and with stator at different distances from the impeller. The results have shown that the best performance is obtained for a stator distance of half the vanes mean chord. The cavitat-ion characteristics have been found to be sensible for the existance of stator, and the risk of cavitation is decreased by using the pump stator.
