摘要： PROBLEM TO BE SOLVED: To provide a water feeder manufacturable at low cost, easily assemblable, and deliverable in a short period by using the same shapes and dimensions of pipes and devices irrespective of whether a suction port and a discharge port are positioned on the left side or the right side and reducing the number of manufactured parts.
SOLUTION: This water feeder comprises pumps P1-P3. The water flowing into the suction port 12 is guided to the pumps through the pipes and devices on the suction side and a suction header 17, pressurized by the pumps P1-P3, and fed from the discharge port 20 to a target water feed position through a discharge header 27 and discharge side pipes. At least the pumps P1-P3 and motors M1-M3 driving the pumps P1-P3 are mounted on a frame 11 bilaterally symmetrically with respect to the vertical centerline of the frame 11. Consequently, the suction port 12 and the discharge port 20 can be disposed on either the left side or the right side by merely replacing a part of the pipes and devices on the suction side and the discharge side.
