摘要

PROBLEM TO BE SOLVED: To provide a submerged pump, and a method for drainage by and a drainage pump car, the submerged pump capable of not only increasing the drainage amount of the drainage pump car so as to increase a drainage capacity and facilitating an installation work but also reducing a cost required for installation by easily allowing a movement by man-power and eliminating the need of the drainage pump car or a crane car having a lift mounted thereon.;SOLUTION: This submerged pump 1 comprises a pump casing 2, a prime mover frame 3, and water-tight cover 4 formed integrally with each other. A pair of rolling rings 12A and 12B are fixedly fitted onto the outer peripheral surface of a cylindrical pump body 5 with a suction port 2B of the pump casing 2 kept open. A handle 13 is installed on the pump body 5 so that the submerged pump 1 can be moved while rolling the rolling rings 12A and 12B by man-power.;COPYRIGHT: (C)2001,JPO
