Claims

[Scope of utility model registration request]

A suction cover 3 is superimposed on the lower surface of a pump casing 1 made of rubber or a material equivalent to this, a pump suction port 4 is provided in the center of the suction cover 3, and through holes 10 are provided at key points in the surrounding wall to form the above-mentioned pump. Casing 1
The bottom plate 7 of the annular strainer 6 that fits on the outer peripheral surface of the suction cover 3 is spaced apart from the lower surface of the suction cover 3 by a constant distance S, and is formed on the inner peripheral surface of the peripheral wall of the annular strainer 6. A large number of ribs 9a that approach each other are vertically arranged at key points on the outer peripheral surface of the pump casing 1, and vertical grooves 9b that communicate with the through holes 10 of the annular strainer 6 are recessed between the ribs 9a. A suction path 12 is formed through the lower surface of the pump cover 3 to the pump suction port 4, and a vertical hole 13 is provided at key points around the bottom plate 7 to fit with the lower end of the rib 9a. A strainer stand for a vertical submersible pump, characterized in that a lower end of a rib 9a is led out from a bottom plate 13 to a lower surface of a bottom plate 7 to form a leg seat 14.
