PROBLEM TO BE SOLVED: To provide a pump of priming structure usable as both a pump for a shallow well and a pump for a deep well. SOLUTION: This pump 10 comprises a body side casing 14 having a pump chamber 40 in which an impeller 25 is disposed, a suction side casing 12 forming a tank chamber 13 and a discharge passage 23 continued to the tank chamber 13 and having a suction port 15 and a first discharge port 17 and a second discharge port 16 continued with the discharge passage 23, and a partition plate 22 partitioning the casings 12, 14 from each other. The impeller 25 is rotated to suck water from the suction port 15, and discharge water from the first discharge port 17 and the second discharge port 18. A pressure regulating valve 30 is detachably disposed above the suction side casing 12 on the upstream side of the discharge passage 23. The opening parts of the suction port 15 and the second discharge port are arranged parallel with each other, and the opening part of the second discharge port 18 is openably formed at the lower part of the suction side casing 12.
