PURPOSE:To readily install a pumping device by obliquely connecting a coupling pipe to a pressure tank. CONSTITUTION:A pressure tank 3 is provided with a connection opening 16 obliquely opening relative to a coupling pipe at a position somewhat upwardly away from a bottom end of a circumferential surface thereof, and bolts 17 are fitted at a circumferential edge of the connection opening in an obliquely downward direction thereof. The pressure tank 3 is disposed on the coupling pipe 2 and is fixed by the bolts 17 inserted through holes formed in a flange 9 at an opening edge of the coupling pipe and threadedly engaged with nuts 18. There is provided a partition plate 14 at a lower side of a position where an oblique opening surface 13 is divided into two ways, thus partitioning the coupling pipe 2 into a pumping passage 4 and a discharge passage 5. A lower flange 6 of the pumping passage 4 is disposed on a discharge port flange 7 of a pump body 1, and both the flanges 6 and 7 are fixed by bolts 8. |
