<p>PROBLEM TO BE SOLVED: To block mechanical noise and fluid noise generated during operation of a pump from transmitting through a transmission pass, and to effectively reduce radial noise of the pump. SOLUTION: In an enclosure in which a pump body 1 is arranged in a cover 8, opening part 5 in which pipe lines 11, 12 connected to the pump body 1 are inserted, are sealed by elastic members 4 which creates a vibration mode having less acoustic radiation at a frequency of frequency noise generated from the pump body 1, and which have a heat transmissivity larger than that of the cover 8.</p> |
