| description | PROBLEM TO BE SOLVED: To provide a vibration attenuation technique capable of improving the degree of freedom of installation regarding a pump device.SOLUTION: A pump device includes: a vertical shaft pump having a first rotation shaft extending in a vertical direction; an electric motor which has a second rotation shaft extending in a vertical direction and is arranged on the upper side than the vertical shaft pump, and in which the lower edge part of the second rotation shaft is connected with the upper edge part of the first rotation shaft; a frame which is installed between the vertical shaft pump and the electric motor and supports the electric motor; and a dynamic vibration absorber which is installed on an inner part of the frame and attenuates vibrations of the electric motor. The dynamic vibration absorber includes an oscillating body having a heavy bob, is suspended while being supported by the frame and can oscillate in the predetermined direction. |
