Claims

[Scope of Claim for Utility Model Registration] A flow path 1 is provided between the motor chamber 2 and the pump swirl chamber 3, and the tip 4 of the motor shaft is introduced into the swirl chamber 3 and the impeller 5 is fitted to the flow path 1. In a submersible pump in which a suction port 6 facing the passage 1 is bored in the suction cover 7 of the pump swirl chamber 3, and a discharge port 8 is opened in the circumferential direction, the mouth edge of the suction port 6 is provided with a rotary blade described later. A fixed blade 10 facing 9a and 9b is formed on the surface of the suction cover 7, and a leading portion 4 of the motor shaft leading from the motor chamber 2 to the pump swirl chamber 3 is formed.
' has a rotary body 9 fitted therein by a reversible mounting structure, and rotary blades 9a are provided on both the front and back surfaces of the rotary body 9. 9b, and when the rotary body 9 is mounted with one surface Ta facing the fixed blade 10, the rotary blade 9a of the mold surface Ta and the fixed blade 10 constitute one mechanism for cutting foreign matter, and
A submersible pump characterized in that when the rotary body 9 is mounted with the other surface Tb facing the fixed blade 10, the rotary blade 9a of the mold surface Tb and the fixed blade 10 can constitute a foreign matter cutting mechanism. Mechanism for cutting off contaminants.
