PROBLEM TO BE SOLVED: To provide a submerged pump device A in which a submerged pump 2 allowing the installation on the bottom of a liquid tank and the pull-up from the inside of the liquid tank is supported with respect to a fixed drain pipe 6 in the liquid tank, wherein various inconveniences of the submerged pump 2 which results from relative displacement with respect to the fixed drain pipe 6. SOLUTION: The device is equipped with a detachable coupling pipe 4 whose tip surface abuts a base end surface of a fixed drain pipe 6 when installing the submerged pump 2 on the bottom of a liquid tank. An elastic coupling part 5 is arranged in an intermediate position in the detachable coupling pipe 4. A connection mechanism part 13 side and submerged pump 2 side in the detachable coupling pipe 4 are elastically coupled with the elastic coupling part 5. COPYRIGHT: (C)2009,JPO&INPIT
