| Abstract: | Efficiency of a centrifugal pump is known to drop rapidly with a decrease of specific speed n_s in the range of n_s≤100. However, below n_s=60 [m, m^3/min, min^<-1>], the pump efficiency is not yet clear, and the spiral angle of volute casing becomes too small to manufacture. To solve this problem, a circular casing is considered appropriate in the very low n_s range. The present study is aimed to reveal the relation between pump efficiency and a specific speed in the range of n_s≤60, when a circular casing is used. The results show that a circular casing gives higher efficiency than a spiral casing, and that radial thrust is considerably small in both casings compared with that of ordinary specific speed pump. |
