Abstract

PURPOSE: To facilitate the molding of the synthetic resin of an air-water separating chamber in synthetic resin, and to improve anticorrosion and producibility while efficiently priming water, in a device provided with the air-water separating chamber at the discharge side of a pump portion.
CONSTITUTION: An air-water separating chamber 8 molded with synthetic resin in a shape that is unified with a check valve chamber 6 is placed on an upper portion of a pump portion 2 through a packing 4. A water supply passage 10, in which water discharged from a pump flows, is vertically mounted to the air-water separating chamber 8 integrally, and a priming port 14 normally closed by means of a plug 12, which can freely be mounted and demounted, is installed just above the water supply passage 10. A cap type shielding body 18, which opens a water-conveyance port 16 to one portion, is disposed to a priming port 14 portion in a mounting-and-demounting-free shape. Thus, the air-water separating chamber 8, to which the water supply passage 10 is vertically installed, and a screw portion 30 of the priming port 14 are integrally molded simultaneously by rapping only in the upper and lower directions while priming can preferably be introduced at the air- water separating chamber 8 side by means of the shielding body 18.
