Claims

[Scope of Claim for Utility Model Registration] 1. In a submersible pump with a vortex impeller attached to the end of the motor shaft, the pump casing is divided into an intermediate casing and a lower casing, and the lower casing flow path has an upper open shape without becoming bag-shaped, A plurality of integrally constructed legs protruding from each other at intervals are provided on the underside of the lower casing, and the legs include:
A strainer is provided so as to extend to the outer circumferential edge of the lower casing, to be inscribed in the outer circumferential edge of the lower casing with a narrow gap, and to surround the outer circumference of the lower casing, and to support the strainer and the lower casing from below, a bottom plate and an intermediate A submersible pump characterized in that a bottom plate, a lower casing, and a strainer are integrally assembled by being held between the casing and tightened with bolts. 2. The submersible pump according to claim 1, wherein the head of a bolt for attaching the intermediate casing to the lower end of the motor projects toward the lower casing, and a recess is provided in the lower casing so that the bolt head fits into a narrow gap. . 3. The submersible pump according to claim 1 or 2, wherein the lower casing is made of a rubber elastic body.
