PROBLEM TO BE SOLVED: To provide a self priming pump showing high gas water separation effect and providing high water suction head. SOLUTION: A first casing 12 and a second casing 14 partitioned by a partition plate 22 are formed. A pump chamber 30 and a second tank chamber 32 are formed inside of the second casing 14. A first tank chamber 13 is formed inside of the first casing 12. Water flowing-in from an inlet 16 provided on the first casing 12 flows in the first tank chamber 13 through an inlet pipe 18, a pump chamber 30 and the second tank chamber 32. Flowing-in water flows in a direction of an outlet 78 by a straightening plate 106 and is circulated inside of the first tank chamber 13 by a circulation passage 112. COPYRIGHT: (C)2006,JPO&NCIPI
