Abstract To solve the problem of the casing strength of the 1200LW 60 vertical type centrifugal pumps for the BeiGan secondary station of DongLei Ⅱ, the casing thickness designed by the water pump manufacturers is analysed further. On the basis of recommended formula in pump textbooks and handbooks available, it has been concluded that there is something wrong with the value selection by the pump manufacturer and thus the correct value range is obtained for the pump casing thickness after strength analysis. By demonstration, the value range can not only satisfy the needs of casing thickness in strength and rigidity, but also be suited for the conditions of the pumping project along the Yellow River Basin.
