PURPOSE:To facilitate assembling of a submersible pump by arranging its rising section around the framing body on the output shaft end side in such a manner as surrounding the body along direction of the axis, forming an outer flange in connection to the rising section, and installing a submersible motor having its water supply hole in the rising section. CONSTITUTION:In the shaft seal case 9, a cylindrical rising section 20, having a diameter equal to the diameter of the motor, is installed, and a flange 21 is connected to the rising section 20 such that it extends from the rising section 20 to the outside. The flange 21 is in contact, through sealants 24, 25, with the upper end faces of a suction cover 22 of the pump and a suction casing 23 which is arranged at some distance on the outer periphery of the motor. The pump can be dismantled to a pump casing 74-2, a sleeve 93, an impeller 46-2, a collar 91 and a suction cover 22. Accordingly, the pump can also be assembled more easily.
