Abstract

PURPOSE: To improve self-priming performance in case of high suction height by installing the deflection plate for preventing air swallowing-up, on a part of a discharge port.
CONSTITUTION: The deflection plate 7 which is formed by utilizing a part of a packing 8 is installed so as to shield a part on the partition plate 6 side of the exit of a passage 12. When a runner 1 is revolved, the air on the upstream side from a check valve is sucked and mixed with the priming water, and air-water mixed fluid is formed, and almost all of the fluid flows into a water separating tank 5 mainly from the passage 12. While, a portion flows crosswise into the vicinity of the inlet of a passage 13 through the deflecting plate 7. While, the fluid which flows into the water separating tank 5 separates air from water in said tank, and the only the water after separation flows backward into the suction side from the passage 13 through a casing water passage.
