Abstract
PURPOSE: To reduce a self-priming pump cost by resinifying without impairing a self-priming performance where a check valve chamber is merged with the top of a pump casing and an air-water separation chamber.
CONSTITUTION: A self-priming pump is comprising a pump casing 1, with the top of which a check valve chamber 3a being connected, and a water conveying chamber 3 wherein an air-water separation chamber 3g is merged in one body. A false hole 3m is provided having a diameter approximately equal to a water passage 3d of the water conveying case 3 and a water passage 3d communicated with the air- water separation chamber 3g, besides, an opening port 3n which is extensively opened on the side of the air-water separation chamber 3g in opposition to the false hole 3m being provided permitting the false hole 3m to seal with a seal material 10, closing, further, the opening port 3n with a cover 11 having a water-feed passage 7 by means of a gasket 12 having a water passage at downstream of upper opening port of the water feed passage 7, enabling to resinify by use of a mold of the water conveying case 3.
