AB  - The aim of the study is to determine the optimal structural parameters for a plastic centrifugal pump inducer within the framework of an orthogonal experimental method. For this purpose, a numerical study of the related flow field is performed using CFX. The shaft power and the head of the pump are taken as the evaluation indicators. Accordingly, the examined variables are the thickness (S), the blade cascade degree (t), the blade rim angle (β1), the blade hub angle (β2) and the hub length (L). The impact of each structural parameter on each evaluation index is examined and special attention is paid to the following combinations: S2 mm, t 2, β1 235°, β2 360° and L 140 mm (corresponding to a maximum head of 98.15 m); S 5 mm, t 1.6, β1 252°, β2 350° and L 140 mm (corresponding to a minimum shaft power of 63.06 KW). Moreover, using least squares and fish swarm algorithms, the pump shaft power and head are further optimized, yielding the following optimal combination: S 5 mm, t 1.9, β1 252°, β2 360° and L 145 mm (corresponding to the maximum head of 91.90 m, and a minimum shaft power of 64.83 KW).
